press releases, and in oral and written statements made by or with the approval of the Company that are not statements of historical fact and constitute forward-looking statements within the meaning of the PSLRA. Such forward-looking statements, in
addition to historical information, which involve risk and uncertainties, are based on the beliefs, assumptions and expectations of management of the Company. Words such as &#147;expects&#148;, &#145;believes&#148;, &#147;should&#148;,

on a number of assumptions that could ultimately prove inaccurate and, therefore, there can be no assurance that they will prove to be accurate.&nbsp;Actual results and outcomes may vary materially from what is expressed or forecast in such
statements due to various risks and uncertainties. These risks and uncertainties include, among other things, the possibility of drilling cost overruns and technical difficulties, volatility of oil and gas prices, competition, risks inherent in the
Company&#146;s oil and gas operations, the inexact nature of interpretation of seismic and other geological and geophysical data, imprecision of reserve estimates, and the Company&#146;s ability to replace and expand oil and gas reserves.
Accordingly, stockholders and potential investors are cautioned that certain events or circumstances could cause actual results to differ materially from those projected. The forward looking statements are made as of the date of this Report and
other than as required by the federal securities laws, the Company assumes no obligation to update the forward-looking statement or to update the reasons why actual results could differ from those projected in the forward-looking statements. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">PrimeEnergy Corporation (the &#147;Company&#148;) was organized in March, 1973, under the laws of the State of Delaware. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We are an independent oil and natural gas company engaged in acquiring, developing and producing oil and natural gas. We presently own
producing and <FONT STYLE="white-space:nowrap">non-producing</FONT> properties located primarily in Texas, Oklahoma and West Virginia. All of our oil and gas properties and interests are located in the United States. Through our subsidiaries Prime
Operating Company, Eastern Oil Well Service Company and EOWS Midland Company, we act as operator and provide well servicing support operations for many of the onshore oil and gas wells in which we have an interest, as well as for third parties. We
are also active in the acquisition of producing oil and gas properties through joint ventures with industry partners. Our subsidiary, PrimeEnergy Management Corporation (&#147;PEMC&#148;), acts as the managing general partner of six oil and gas
limited partnerships (the &#147;Partnerships&#148;), and acts as the managing trustee of two asset and income business trusts (&#147;the Trusts&#148;). </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><U>Exploration, Development and Recent Activities </U></B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company&#146;s activities include development and exploratory drilling. Our strategy is to develop a balanced portfolio of drilling
prospects that includes lower risk wells with a high probability of success and higher risk wells with greater economic potential. Based upon the results of horizontal wells drilled by us and other offsetting operators and historical vertical well
performance, we decided in 2016 to reduce the number of vertical wells in our drilling program and drill primarily horizontal wells. We believe horizontal development of our resource base provides superior returns relative to vertical drilling by
accessing a larger base of reserves in each target pay zone with a lateral wellbore. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Maintaining a strong balance sheet and ample
liquidity are key components of our business strategy. For 2018, we will continue our focus on preserving financial flexibility and ample liquidity as we manage the risks facing our industry. Our 2018 capital budget is reflective of current
commodity prices and has been established based on an expectation of available cash flows, with any cash flow deficiencies expected to be funded by borrowings under our revolving credit facility. As we have done historically to preserve or enhance
liquidity we may adjust our capital program throughout the year, divest <FONT STYLE="white-space:nowrap">non-strategic</FONT> assets, or enter into strategic joint ventures. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In accordance with SEC rules governing the scheduling of the drilling of PUD reserves we have only included in our <FONT
STYLE="white-space:nowrap">year-end</FONT> reserve report the 22 PUD locations for which we have definitive plans to drill. The Company has a working interest in eight of these PUD locations and an overriding royalty interest only in the remaining
fourteen locations. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Since the start of our West Texas horizontal drilling program in 2015 the Company has participated in 56 horizontal
wells in West Texas. In 39 of these wells, the Company owns an average of 22% working interest. All 39 wells are on production. As to 14 wells of the 56 total, the Company participated with less than 1% working interest. Of these 14 wells, seven are

Upton County, Texas, we are developing a contiguous 3,900 acre block with our joint venture partner, Apache Corporation, where the Company holds approximately 48% interest in 2,606 gross acres. Through
<FONT STYLE="white-space:nowrap">year-end</FONT> 2017, <FONT STYLE="white-space:nowrap">twenty-two</FONT> wells have been drilled and completed in this joint venture. Sixteen of these were drilled and completed in 2017 at a gross cost of
$106,267,000. The Company invested a net $43.3 million with an average 34.8% interest. In the first quarter of 2018, an additional three wells have been drilled and are in the process of being completed at an expected gross cost of $25,441,000. We
have a $38.25 million interest in these wells and our expected net cost will be approximate $9,371,000. Apache Corporation has indicated plans to continue to PAD drill the acreage and future phases of the development are expected to result in
approximately 40 additional horizontal wells being drilled at a cost of about $312&nbsp;million. The Company owns various interests ranging from 14% to 49% in the lands to be developed in this project and expect our share of these capital
expenditures to be approximately $80&nbsp;million. The actual number of wells drilled, the cost, and the timing of drilling may vary based upon commodity market conditions. Apache&#146;s drilling plans indicate an additional eight wells will be
drilled later this year at a cost of $50&nbsp;million, of which our share is approximately $24&nbsp;million. These wells meet the definition of proved undeveloped reserves, however, they were not included in our

surface use and restoration of properties on which wells are drilled, and the plugging and abandoning of wells. Our operations are also subject to various conservation laws and regulations. These include the regulation of the size of drilling and
spacing units or proration units, the density of wells that may be drilled in a given field and the unitization or pooling of oil and natural gas properties. Some states allow the forced pooling or integration of tracts to facilitate exploration
while other states rely on voluntary pooling of lands and leases. In addition, state conservation laws establish maximum rates of production from oil and natural gas wells, generally prohibiting the venting or flaring of natural gas and imposing
certain requirements regarding the ratability of production. The effect of these regulations is to limit the amounts of oil and natural gas we can produce from our wells, and to limit the number of wells or the locations where we can drill.

and regulations undergo constant review and often are amended, expanded and reinterpreted, we are unable to predict the future cost or impact of regulatory compliance. The failure to comply with
these rules and regulations can result in substantial penalties. The regulatory burden on the oil and natural gas industry increases the cost of doing business and, consequently, affects profitability. Our competitors in the oil and natural gas
industry are subject to the same regulatory requirements and restrictions affecting operations. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>Regulation of Transportation and Sale of Natural
Gas: </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Historically, the transportation and sale for resale of natural gas in interstate commerce have been regulated pursuant to
the Natural Gas Act of 1938, as amended (&#147;NGA&#148;), the Natural Gas Policy Act of 1978, as amended (&#147;NGPA&#148;), and regulations promulgated thereunder by the Federal Energy Regulatory Commission (&#147;FERC&#148;) and its predecessors.
In the past, the federal government has regulated the prices at which natural gas could be sold. While sales by producers of natural gas can currently be made at uncontrolled market prices, Congress could reenact price controls in the future.
Deregulation of wellhead natural gas sales began with the enactment of the NGPA. In 1989, Congress enacted the Natural Gas Wellhead Decontrol Act, as amended (the &#147;Decontrol Act&#148;). Effective January&nbsp;1, 1993, the Decontrol Act removed
all NGA and NGPA price and <FONT STYLE="white-space:nowrap">non-price</FONT> controls affecting wellhead sales of natural gas and deregulated natural gas prices for all &#147;first sales&#148; of natural gas, which definition covers all sales of our
own production. In addition, as part of the broad industry restructuring initiatives described below, the FERC has granted to all producers such as us a &#147;blanket certificate of public convenience and necessity&#148; authorizing the sale of gas
for resale without further FERC approvals. As a result, all of our produced natural gas may now be sold at market prices, subject to the terms of any private contracts that may be in effect. In addition, under the provisions of the Energy Policy Act
of 2005, as amended (the &#147;2005 Act&#148;), the NGA has been amended to prohibit any forms of market manipulation in connection with the purchase or sale of natural gas. Pursuant to the 2005 Act, the FERC established new regulations that are
intended to increase natural gas pricing transparency through, among other things, requiring market participants to report their gas sales transactions annually to the FERC, and new regulations that require certain
<FONT STYLE="white-space:nowrap">non-interstate</FONT> pipelines to post daily scheduled volume information and design capacity for certain points on their systems. The 2005 Act also significantly increased the penalties for violations of the NGA
and the FERC&#146;s regulations. In 2010, the FERC issued Penalty Guidelines for the determination of civil penalties in an effort to add greater fairness, consistency and transparency to its enforcement program. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our natural gas sales prices continue to be affected by intrastate and interstate gas transportation regulation, because the prices we receive
for our production are affected by the cost of transporting the gas to the consuming market. Through a series of comprehensive rulemakings, beginning with Order No.&nbsp;436 in 1985 and continuing through Order No.&nbsp;636 in 1992 and Order
No.&nbsp;637 in 2000, the FERC has adopted regulatory changes that have significantly altered the transportation and marketing of natural gas. These changes were intended by the FERC to foster competition by, among other things, transforming the
role of interstate pipeline companies from wholesale marketers of gas to the primary role of gas transporters, and by increasing the transparency of pricing for pipeline services. The FERC has also established regulations governing the relationship
of pipelines with their marketing affiliates, which essentially require that designated employees function independently of each other, and that certain information not be shared. The FERC has also implemented standards relating to the use of
electronic data exchange by the pipelines to make transportation information available on a timely basis and to enable transactions to occur on a purely electronic basis. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In light of these statutory and regulatory changes, most pipelines have divested their gas sales functions to marketing affiliates, which
operate separately from the transporter and in direct competition with all other merchants, and most pipelines have also implemented the large-scale divestiture of their gas gathering facilities to affiliated or
<FONT STYLE="white-space:nowrap">non-affiliated</FONT> companies. Interstate pipelines thus now generally provide unbundled, open and nondiscriminatory transportation and transportation-related services to producers, gas marketing companies, local
distribution companies, industrial end users and other customers seeking such services. Sellers and buyers of gas have gained direct access to the particular pipeline services they need, and are better able to conduct business with a larger number
of counterparties. We believe these changes generally have improved our access to markets while, at the same time, substantially increasing competition in the natural gas marketplace. We cannot predict

what new or different regulations the FERC and other regulatory agencies may adopt, or what effect subsequent regulations may have on our activities. Similarly, we cannot predict what proposals,
if any, that affect the oil and natural gas industry might actually be enacted by Congress or the various state legislatures and what effect, if any, such proposals might have on us. Further, we cannot predict whether the recent trend toward federal
deregulation of the natural gas industry will continue or what effect future policies will have on our sale of gas. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In December 2007, the
FERC issued rules (Order No.&nbsp;704) requiring that any market participant that engages in wholesale sales or purchases of natural gas that equal or exceed 2.2&nbsp;million British thermal units (&#147;MMBtu&#148;) during a calendar year must
annually report, starting May&nbsp;1, 2009, such sales and purchases to the FERC. These rules are intended to increase transparency of the wholesale natural gas markets and assist the FERC in monitoring such markets and in detecting market
manipulation. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Additional proposals and proceedings that might affect the natural gas industry are pending before FERC and the courts. The
natural gas industry historically has been very heavily regulated; therefore, there is no assurance that the less stringent regulatory approach recently pursued by FERC will continue. However, we do not believe that any action taken will affect us
in a way that materially differs from the way it affects other natural gas producers, gatherers and marketers. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Intrastate natural gas
transportation is subject to regulation by state regulatory agencies. The basis for intrastate regulation of natural gas transportation and the degree of regulatory oversight and scrutiny given to intrastate natural gas pipeline rates and services
varies from state to state. Insofar as such regulation within a particular state will generally affect all intrastate natural gas shippers within the state on a comparable basis, we believe the regulation of similarly situated intrastate natural gas
transportation in any states in which we operate and ship natural gas on an intrastate basis will not affect our operations in any way that is materially different from the effect of such regulation on competitors. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our sales of crude oil, condensate and natural gas liquids are not currently regulated and are made at negotiated prices. The price received
from the sale of these products is affected by the cost of transporting the products to market. Much of that transportation is through interstate common carrier pipelines, which are regulated by FERC under the Interstate Commerce Act
(&#147;ICA&#148;). FERC requires that pipelines regulated under the ICA file tariffs setting forth the rates and terms and conditions of service, and that such service not be unduly discriminatory or preferential. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Effective January&nbsp;1, 1995, the FERC implemented regulations generally grandfathering all previously approved interstate transportation
rates and establishing an indexing system for those rates by which adjustments are made annually based on the rate of inflation, subject to certain conditions and limitations. These regulations may tend to increase the cost of transporting oil and
natural gas liquids by interstate pipeline, although the annual adjustments may result in decreased rates in a given year. Every five years, the FERC must examine the relationship between the annual change in the applicable index and the actual cost
changes experienced in the oil pipeline industry In December 2015, to implement this required five-year <FONT STYLE="white-space:nowrap">re-determination,</FONT> the FERC established an upward adjustment in the index to track oil pipeline cost
changes and determined that the Producer Price Index for Finished Goods plus 1.23% should be the oil pricing index for the five-year period beginning July&nbsp;1, 2016. The result of indexing is a &#147;ceiling rate&#148; for each rate, which is the
maximum at which the pipeline may set its interstate transportation rates. A pipeline may also file <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">cost-of-service</FONT></FONT> based rates if rate indexing will be insufficient to
allow the pipeline to recover its costs. Rates are subject to challenge by protest when they are filed or changed. For indexed rates, complaints alleging that the rates are unjust and unreasonable may only be pursued if the complainant can show that
a substantial change has occurred since the enactment of the Energy Policy Act of 1992 in either the economic circumstances of the pipeline or in the nature of the services provided, that were a basis for the rate. There is no such limitation on
complaints alleging that the pipeline&#146;s rates or term and conditions of service are unduly discriminatory or preferential. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Another
FERC matter that may impact our transportation costs relates to a policy that allows a pipeline structured as a master limited partnership or similar <FONT STYLE="white-space:nowrap">non-corporate</FONT> entity to include in its rates a tax
allowance </P>

(&#147;RCRA&#148;), provides a framework for the safe disposal of discarded materials and the management of solid and hazardous wastes. The direct disposal of operational wastes into offshore waters is also limited under the authority of the Clean
Water Act. When injected underground, oil and natural gas wastes are regulated by the Underground Injection Control program under the Safe Drinking Water Act. If wastes are classified as hazardous, they must be properly transported, using a uniform
hazardous waste manifest, documented, and disposed at an approved hazardous waste facility. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>Resource Conservation and Recovery
Act.</I></B> The RCRA is the principal federal statute governing the treatment, storage and disposal of hazardous wastes. RCRA imposes stringent operating requirements and liability for failure to meet such requirements on a person who is either a
&#147;generator&#148; or &#147;transporter&#148; of hazardous waste or an &#147;owner&#148; or &#147;operator&#148; of a hazardous waste treatment, storage or disposal facility. At present, RCRA includes a statutory exemption that allows most oil
and natural gas exploration and production waste to be classified as nonhazardous waste. A similar exemption is contained in many of the state counterparts to RCRA. As a result, we are not required to comply with a substantial portion of RCRA&#146;s
requirements because the operations generate minimal quantities of hazardous wastes. At various times in the past, proposals have been made to amend RCRA to rescind the exemption that excludes oil and natural gas exploration and production wastes
from regulation as hazardous waste. Repeal or modification of the exemption by administrative, legislative or judicial process, or modification of similar exemptions in applicable state statutes, would increase the volume of hazardous waste we are

Act.</I></B> Underground injection is the subsurface placement of fluid through a well, such as the reinjection of brine produced and separated from oil and natural gas production. The Safe Drinking Water Act establishes a regulatory framework for
underground injection, with the main goal being the protection of usable aquifers. The primary objective of injection well operating requirements is to ensure the mechanical integrity of the injection apparatus and to prevent migration of fluids
from the injection zone into underground sources of drinking water. Hazardous-waste injection well operations are strictly controlled, and certain wastes, absent an exemption, cannot be injected into underground injection control wells. In Louisiana
and Texas, no underground injection may take place except as authorized by permit or rule. We currently own and operate various underground injection wells. Failure to abide by the permits could subject us to civil and/or criminal enforcement. We

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>Hydraulic Fracturing.</I></B> Many of our exploration and production operations depend on the use of hydraulic fracturing to enhance
production from oil and gas wells. This technology involves the injection of fluids, usually consisting mostly of water but typically including small amounts of several chemical additives, as well as sand into a well under high pressure in order to
create fractures in the rock that allow oil or gas to flow more freely to the wellbore. Most of our wells would not be economical without the use of hydraulic fracturing to stimulate production from the well. Hydraulic fracturing operations have
historically been overseen by state regulators as part of their oil and gas regulatory programs. However, bills have been introduced in Congress that would subject hydraulic fracturing to federal regulation under the Safe Drinking Water Act. If
adopted, these bills could result in additional permitting requirements for hydraulic fracturing operations as well as various restrictions on those operations. These permitting requirements and restrictions could result in delays in operations at
well sites as well as increased costs to make wells productive. Moreover, the bills introduced in Congress would require the public disclosure of certain information regarding the chemical makeup of hydraulic fracturing fluids, many of which are
proprietary to the service companies that perform the hydraulic fracturing operations. Such disclosure could make it easier for third parties to initiate litigation against us in the event of perceived problems with drinking water wells in the
vicinity of an oil or gas well or other alleged environmental problems. In addition to these federal legislative proposals, some states and local governments have adopted, and others are considering adopting, regulations that could restrict
hydraulic fracturing in certain circumstances, including but not limited to requirements regarding chemical disclosure, casing and cementing of wells, withdrawal of water for use in high-volume hydraulic fracturing of horizontal wells, baseline
testing of nearby water wells, and restrictions on the type of additives that may be used in hydraulic fracturing operations. If these types of conditions are adopted, we could be subject to increased costs and possibly limits on the productivity of
certain wells. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>Greenhouse Gas.</I></B> In response to studies suggesting that emissions of carbon dioxide and certain other gases
may be contributing to global climate change, the United States Congress has considered legislation to reduce emissions of greenhouse gases from sources within the United States between 2012 and 2050. In addition, many states have already taken
legal measures to reduce emissions of greenhouse gases, primarily through the planned development of greenhouse gas emission inventories and/or regional greenhouse gas cap and trade programs. The EPA has also begun to regulate carbon dioxide and

of Interior (&#147;DOI&#148;) to evaluate whether certain proposed activities would cause serious harm or damage to the marine, coastal or human environment. Similarly, NEPA requires DOI and other federal agencies to evaluate major agency actions
having the potential to significantly impact the environment. In the course of such evaluations, an agency would have to prepare an environmental assessment and, potentially, an environmental impact statement. CZMA, on the other hand, aids states in
developing a coastal management program to protect the coastal environment from growing demands associated with various uses, including offshore oil and natural gas development. In obtaining various approvals from the DOI, we must certify that we

national, state and local efforts to protect air quality. Operations utilize equipment that emit air pollutants subject to federal and state air pollution control laws. These laws require utilization of air emissions abatement equipment to achieve
prescribed emissions limitations and ambient air quality standards, as well as operating permits for existing equipment and construction permits for new and modified equipment. Air emissions associated with offshore activities are projected using a

applicable to the petroleum industry. For U.S. income tax reporting purposes, intangible drilling and development costs incurred or borne during the year are permitted to be deducted currently, rather than capitalized. As an independent producer, we
are also entitled to a deduction for percentage depletion with respect to the first 1,000 barrels per day of domestic crude oil (and/or equivalent units of domestic natural gas) produced, if such percentage depletion exceeds cost depletion.
Generally, this deduction is computed based upon the lesser of 100% of the net income, or 15% of the gross income from a property, without reference to the basis in the property. The amount of the percentage depletion deduction so computed which may
be deducted in any given year is limited to 65% of taxable income. Any percentage depletion deduction disallowed due to the 65% of taxable income test may be carried forward indefinitely. </P>

business of acquiring producing properties and <FONT STYLE="white-space:nowrap">non-producing</FONT> leases suitable for exploration and development is highly competitive. Our competition, in our efforts to acquire both producing and <FONT

greater than those available to us. Furthermore, domestic producers of oil and gas must not only compete with each other in marketing their output, but must also compete with producers of imported oil and gas and alternative energy sources such as
coal, nuclear power and hydroelectric power. Competition among petroleum companies for favorable oil and gas properties and leases can be expected to increase. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The availability of a ready market for any oil and gas produced by us at acceptable prices per unit of production will depend upon numerous

competitive fuels, fluctuation in demand, governmental regulation of production, refining, transportation and sales, general national and worldwide economic conditions, and use and allocation of oil and gas and their substitute fuels. There is no

ability to borrow funds or obtain additional capital depend substantially on prevailing prices for natural gas and oil. Lower commodity prices may reduce the amount of natural gas and oil that we can produce economically. Natural gas prices, based
on the twelve-month average of the first of the month Henry Hub index price, were $2.98 per MMBTU in 2017 compared to $2.49 per MMBTU in 2016, and have ranged from $3.58 to $2.61 per MMBTU for the first three months of 2018. Oil prices, based on the
NYMEX monthly average price, were $50.99 per barrel in 2017 compared to $43.29 per barrel in 2016, and have increased to $62.93 through March 2018. Any substantial or extended decline in future natural gas or crude oil prices would have, a material
adverse effect on our future business, financial condition, results of operations, cash flows, liquidity or ability to finance planned capital expenditures and commitments. Furthermore, substantial, extended decreases in natural gas and crude oil
prices may cause us to delay or postpone a significant portion of our exploration, development and exploitation projects or may render such projects uneconomic, which may result in significant downward adjustments to our estimated proved reserves
and could negatively impact our ability to borrow and cost of capital and our ability to access capital markets, increase our costs under our revolving credit facility, and limit our ability to execute aspects of our business plans. </P>

constant throughout the life of the properties. Actual future prices and costs may differ materially from those used in the net present value estimate, and future net present value estimates using then current prices and costs may be significantly

future drilling opportunities, including development and infill drilling activities. These drilling locations and prospects represent a significant part of the Company&#146;s future drilling plans. The Company&#146;s ability to drill and develop
these locations depends on a number of factors, including the availability of capital, seasonal conditions, regulatory approvals, negotiation of agreements with third parties, commodity prices, costs, access to and availability of equipment,
services, resources and personnel and drilling results. Changes in the laws or regulations on which the Company relies in planning and executing its drilling programs could adversely impact the Company&#146;s ability to successfully complete those
programs. For example, under current Texas laws and regulations the Company may receive permits to drill, and may drill and complete, certain horizontal wells that traverse one or more units and/or leases; a change in those laws or regulations could
adversely impact the Company&#146;s ability to drill those wells. Because of these uncertainties, the Company cannot give any assurance as to the timing of these activities or that they will ultimately meet the Company&#146;s expectations for

production is, therefore, highly dependent on our level of success in finding or acquiring additional reserves. We may not be able to replace reserves through our exploration, development and exploitation activities or by acquiring properties at
acceptable costs. Low natural gas and oil prices may further limit the kinds of reserves that we can develop economically. Lower prices also decrease our cash flow and may cause us to decrease capital expenditures. </P>

capital markets may be restricted at a time when we desire, or need, to raise capital, which could have an impact on our flexibility to react to changing economic and business conditions. Adverse economic and market conditions could adversely affect
the collectability of our trade receivables and cause our commodity hedging counterparties to be unable to perform their obligations or to seek bankruptcy protection. Future challenges in the economy could also lead to reduced demand for natural gas
which could have a negative impact on our revenues. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our debt agreements also require compliance with covenants to maintain specified

could lead to a default under those ratios. Because the calculations of the financial ratios are made as of certain dates, the financial ratios can fluctuate significantly from period to period. A prolonged period of decreased natural gas and oil
prices or a further decline could further increase the risk of our inability to comply with covenants to maintain specified financial ratios. In order to provide a margin of comfort with regard to these financial covenants, we may seek to reduce our
capital expenditure plan, sell <FONT STYLE="white-space:nowrap">non-strategic</FONT> assets or opportunistically modify or increase our derivative instruments to the extent permitted under our debt agreements. In addition, we may seek to refinance

customers and contractors who provide contractual indemnification protection may not in all cases maintain adequate insurance to support their indemnification obligations. Our insurance or indemnification arrangements may not adequately protect us

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Most of our exploration and production operations depend on the use of hydraulic fracturing to enhance production from oil and gas wells. This
technology involves the injection of fluids&#151;usually consisting mostly of water but typically including small amounts of several chemical additives&#151;as well as sand or other proppants into a well under high pressure in order to create
fractures in the rock that allow oil or gas to flow more freely to the wellbore. Most of our wells would not be economical without the use of hydraulic fracturing to stimulate production from the well. Hydraulic fracturing operations have
historically been overseen by state regulators as part of their oil and gas regulatory programs; however, the EPA has asserted federal regulatory authority over certain hydraulic fracturing activities involving diesel under the Safe Drinking Water
Act and has released permitting guidance for hydraulic fracturing activities that use diesel in fracturing fluids in those states where EPA is the permitting authority, including Pennsylvania. As a result, we may be subject to additional permitting
requirements for hydraulic fracturing operations as well as various restrictions on those operations. These permitting requirements and restrictions could result in delays in operations at well sites as well as increased costs to make wells
productive. In addition, legislation introduced in Congress would provide for federal regulation of hydraulic fracturing under the Safe Drinking Water Act and require the public disclosure of certain information regarding the chemical makeup of
hydraulic fracturing fluids. If adopted, this legislation could establish an additional level of regulation and permitting at the federal, state or local levels, and could make it easier for third parties opposed to the hydraulic fracturing process
to initiate legal proceedings based on allegations that specific chemicals used in the fracturing process could adversely affect the environment, including groundwater, soil or surface water. Moreover, in May 2014, the EPA announced an Advanced

of Proposed Rulemaking under the Toxic Substances Control Act relating to data collection, including the chemical substances and mixtures used in hydraulic fracturing. Further, in March 2015, the
Department of the Interior&#146;s Bureau of Land Management (BLM) issued a final rule to regulate hydraulic fracturing on public and Indian land; however, enforcement of the rule has been delayed pending a decision in a legal challenge in the U.S.
District Court of Wyoming. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On August&nbsp;16, 2012, the EPA published final rules that establish new air emission control requirements
for natural gas and NGL production, processing and transportation activities, including New Source Performance Standards (NSPS) to address emissions of sulfur dioxide and volatile organic compounds, and National Emission Standards for Hazardous Air
Pollutants (NESHAPS) to address hazardous air pollutants frequently associated with gas production and processing activities. Among other things, these final rules require the reduction of volatile organic compound emissions from natural gas wells
through the use of reduced emission completions or &#147;green completions&#148; on all hydraulically fractured wells constructed or refractured after January&nbsp;1, 2015. In addition, gas wells were required to use completion combustion device
equipment (i.e., flaring) if emissions cannot be directed to a gathering line. Further, the final rules under NESHAPS include maximum achievable control technology (MACT) standards for &#147;small&#148; glycol dehydrators that are located at major
sources of hazardous air pollutants and modifications to the leak detection standards for valves. In December 2014, the EPA finalized additional amendments to these rules that, among other things, distinguished between multiple flowback stages
during completion and clarified that storage tanks permanently removed from service are not affected by any requirements. In July 2015, the EPA finalized two updates to the rules addressing the definition of low pressure gas wells and references to
tanks that are connected to one another. In September 2015, the EPA issued a proposed rule that would update and expand the NSPS by setting additional emissions limits for volatile organic compounds and regulating methane emissions for new and
modified sources in the oil and gas industry. The EPA also issued a proposed rule in September 2015 concerning aggregation of sources that would affect source determinations for air permitting in the oil and gas industry. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Compliance with these requirements, especially the imposition of these green completion requirements and potential methane regulation, may
require modifications to certain of our operations, including the installation of new equipment to control emissions at the well site that could result in significant costs, including increased capital expenditures and operating costs, and could
adversely impact our business. Similarly, aggregating our oil and gas facilities for permitting could result in more complex, costly, and time consuming air permitting. Particularly in regard to obtaining
<FONT STYLE="white-space:nowrap">pre-construction</FONT> permits, the proposed aggregation rule could add costs and cause delays in our operations. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In addition to these federal legislative and regulatory proposals, some states in which we operate, such as West Virginia and Texas, and
certain local governments have adopted, and others are considering adopting, regulations that could restrict hydraulic fracturing in certain circumstances, including requirements regarding chemical disclosure, casing and cementing of wells,
withdrawal of water for use in high-volume hydraulic fracturing of horizontal wells, baseline testing of nearby water wells, and restrictions on the type of additives that may be used in hydraulic fracturing operations. For example, the City of
Denton, Texas adopted a moratorium on hydraulic fracturing in November 2014, though it was later lifted in 2015, and New York issued a statewide ban on hydraulic fracturing in June 2015. In addition, Pennsylvania&#146;s Act 13 of 2012 became law on
February&nbsp;14, 2012 and amended the state&#146;s Oil and Gas Act to, among other things, increase civil penalties and strengthen the Pennsylvania Department of Environmental Protection&#146;s (PaDEP) authority over the issuance of drilling
permits. Although the Pennsylvania Supreme Court struck down portions of Act 13 that made statewide rules on oil and gas preempt local zoning rules, this could lead to additional local restrictions on oil and gas activity in the state. Additional
challenges to Act 13 are pending before the Pennsylvania Supreme Court; however, the timing of any decision is uncertain. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We use a

operating costs and cause delays, interruptions or termination of our operations, the extent of which cannot be predicted, all of which could have an adverse effect on our operations and financial condition. For example, in April 2011, PaDEP called
on all Marcellus Shale natural gas drilling operators to voluntarily cease by May&nbsp;19, 2011 delivering wastewater to those centralized treatment facilities that were grandfathered from the application of PaDEP&#146;s Total Dissolved Solids

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">A number of federal agencies are analyzing, or have been requested to review, a variety of environmental issues associated with hydraulic
fracturing practices. The EPA is conducting a study of the potential environmental effects of hydraulic fracturing on drinking water and groundwater. The EPA released a draft report in June 2015. It concluded that activities have not led to
widespread systematic impacts on drinking water resources in the United States, but there are above and below ground mechanisms by which hydraulic fracturing could affect drinking water resources. This study and other studies that may be undertaken
by EPA or other federal agencies could spur initiatives to further regulate hydraulic fracturing under the Safe Drinking Water Act, the Toxic Substances Control Act, or other statutory and/or regulatory mechanisms. </P>

gas (GHG) emissions have the potential to affect our business in many ways, including increasing the costs to provide our products and services, reducing the demand for and consumption of our products and services (due to change in both costs and
weather patterns), and the economic health of the regions in which we operate, all of which can create financial risks. In addition, legislative and regulatory responses related to GHG emissions and climate change may increase our operating costs.
The United States Congress has previously considered legislation related to GHG emissions. There have also been international efforts seeking legally binding reductions in GHG emissions. For example, in November 2014, the Obama Administration
announced an agreement with China to voluntarily reduce GHG emissions by 26% to 28% of 2005 levels by 2025. Further, the United States joined over 190 countries in Lima, Peru in December 2014 and agreed to draft an emissions reduction plan ahead of
further international climate negotiations in Paris, France in 2015. The United States was actively involved in the negotiations in Paris, which led to the creation of the Paris Agreement. The Paris Agreement will be open for signing on
April&nbsp;22, 2016 and will require countries to review and &#147;represent a progression&#148; in their intended nationally determined contributions, which set emissions reduction goals, every five years, beginning in 2020. The Paris Agreement
sets a goal of keeping warming well below 2 degrees Celsius and sets a target limit of 1.5 degrees Celsius. In addition, increased public awareness and concern may result in more state, regional and/or federal requirements to reduce or mitigate GHG
emissions. For example, in June 2013, the Obama Administration announced its Climate Action Plan, which, among other things, directs federal agencies to develop a strategy for the reduction of methane emissions, including emissions from the oil and
gas sector. Pursuant to this plan, the EPA issued a proposed rule updating New Source Performance Standards and setting requirements for methane emissions and volatile organic compounds in the oil and gas sector in September 2015. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In September 2009, the EPA finalized a mandatory GHG reporting rule that requires large sources of GHG emissions to monitor, maintain records

regulations that went into effect on December&nbsp;30, 2010, specifically for oil and natural gas facilities, including onshore and offshore oil and natural gas production facilities that emit 25,000 metric tons or more of CO2e per year. The rule
required reporting of GHG emissions by regulated facilities to the EPA by March 2012 for emissions during 2011 and annually thereafter. We are required to report our GHG emissions to the EPA each year in March under this rule and have submitted our
annual reports in compliance with the deadline. The EPA also issued a final rule that makes certain stationary sources and newer modification projects subject to permitting requirements for GHG emissions, beginning in 2011, under the CAA. However,
in June 2014, the U.S. Supreme Court, in UARG v. EPA, limited the application of the GHG permitting requirements under the Prevention of Significant Deterioration and Title V permitting programs to sources that would otherwise need permits based on
the emission of conventional pollutants. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Federal and state regulatory agencies can impose administrative, civil and/or criminal penalties

could result in increased costs to (i)&nbsp;operate and maintain our facilities, (ii)&nbsp;install new emission controls on our facilities and (iii)&nbsp;administer and manage any GHG emissions program. If we are unable to recover or pass through a
significant level of our costs related to complying with climate change regulatory requirements imposed on us, it could have a material adverse effect on our results of operations and financial condition. To the extent financial markets view climate
change and GHG emissions as a financial risk, this could negatively impact our cost of and access to capital. Legislation or regulations that may be adopted to address climate change could also affect the markets for our products by making our

becoming more sophisticated and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and systems, and other electronic security breaches that could lead to disruptions in critical systems, unauthorized
release of confidential or otherwise protected information, and corruption of data. These events could damage the Company&#146;s reputation and lead to financial losses from remedial actions, loss of business or potential liability. </P>

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">During 2016 five horizontal wells were drilled in West Texas, two in Oklahoma, and one vertical well was drilled onshore Texas Gulf Coast. In
addition, we had an increase in reserves from overriding royalty interest in 14 horizontal wells drilled in Oklahoma by other operators. Included in our December 31, 2016, reserve report was 1,135 MBoe of proved undeveloped reserves attributable to
20 wells, 19 of which were horizontals. All 20 wells were drilled, completed and put on production in 2017 and 100% of their reserves converted to proved developed producing. </P>

vertical well in Oklahoma. The company also increased reserves through overriding royalty interest in nine new wells. In the first quarter of 2018 the Company is actively participating for 38% interest in three horizontal wells in West Texas that
are in the process of being drilled or completed. The estimated 8/8ths cost of these three wells will be approximately $25.5 Million, of which the Company&#146;s share will be about $9.7 Million. The Company is also participating in three wells in
Oklahoma which are in various stages of being completed and placed on line. The estimated 8/8ths cost of these three wells is $24.6&nbsp;million, of which the Company&#146;s share will be about $1.5 Million. Future development plans have been
established based on an expectation of available cash flows from operations and availability of funds under our revolving credit facility. </P>

technologies and economic data being used in the estimation of our proved reserves include, but are not limited to, electrical logs, radioactivity logs, geologic maps, production data and well test data. The estimated reserves of wells with
sufficient production history are estimated using appropriate decline curves. Estimated reserves of producing wells with limited production history and for undeveloped locations are estimated using performance data from analogous wells in the area.
These wells are considered analogous based on production performance from the same formation and with similar completion techniques. </P>

sulfur, and basic sediment and water) as appropriate. Also in accordance with SEC specifications and U.S. generally accepted accounting principles, changes in market prices subsequent to December&nbsp;31 are not considered. </P>

West Texas activities are concentrated in the Permian Basin in Texas and New Mexico. The Spraberry field was discovered in 1949, encompasses eight counties in West Texas and the Company believes it is the largest oil field in the United States. The
field is approximately 150 miles long and 75 miles wide at its widest point. The oil produced is West Texas Intermediate Sweet, and the gas produced is casing-head gas with an average energy content of 1,400 Btu. The oil and gas are produced
primarily from six formations; the upper and lower Spraberry, the Dean, the Wolfcamp, the Strawn and the Atoka, at depths ranging from 6,700 feet to 11,300 feet. This region is managed from our office in Midland, Texas. As of December 31, 2017, we
had 566 wells (515 net) in the West Texas area, of which 363 wells are operated by us. Principal producing intervals are in the Spraberry, Wolfcamp and San Andres formations at depths ranging from 5,500 to 12,500 feet. Average net daily production
in 2017 was 3,072 Boe. At December 31, 2017, we had 7,389 MBoe of proved reserves in the West Texas area, or 69% of our total proved reserves. We maintain an acreage position of over 20,443 gross (13,104 net) acres in the Permian Basin in West
Texas, primarily in Reagan, Upton, Martin and Midland counties and believe this acreage has significant resource potential for horizontal drilling in the Spraberry and Wolfcamp intervals. We operate a field service group in this region utilizing
eight workover rigs, four hot oiler trucks and one kill truck. Services including well service support, site preparation and construction services for drilling and workover operations are provided to third party operators as well as utilized in our
own operated wells and locations. At December 31, 2017 the Company had identified and committed to participate in three Proved Undeveloped horizontal drilling locations. As of March 31, 2018 all three of these wells have been drilled and are either

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We are an independent oil and natural gas company engaged in acquiring, developing and producing oil and natural gas. We presently own
producing and <FONT STYLE="white-space:nowrap">non-producing</FONT> properties located primarily in Texas, Oklahoma and West Virginia. In addition, we own a substantial amount of well servicing equipment. All our oil and gas properties and interests
are located in the United States. Assets in our principal focus areas include mature properties with long-lived reserves and significant development opportunities as well as newer properties with development and exploration potential. We believe our
balanced portfolio of assets and our ongoing hedging program position us well for both the current commodity price environment and future potential upside as we develop our attractive resource opportunities. Our primary sources of liquidity are cash
generated from our operations and our credit facility. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We attempt to assume the position of operator in all acquisitions of producing properties
and will continue to evaluate prospects for leasehold acquisitions and for exploration and development operations in areas in which we own interests. We continue to actively pursue the acquisition of producing properties. To diversify and broaden
our asset base, we will consider acquiring the assets or stock in other entities and companies in the oil and gas business. Our main objective in making any such acquisitions will be to acquire income producing assets to build stockholder value
through consistent growth in our oil and gas reserve base on a cost-efficient basis. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our cash flows depend on many factors, including the
price of oil and gas, the success of our acquisition and drilling activities and the operational performance of our producing properties. We use derivative instruments to manage our commodity price risk. This practice may prevent us from receiving
the full advantage of any increases in oil and gas prices above the maximum fixed amount specified in the derivative agreements and subjects us to the credit risk of the counterparties to such agreements. Since all our derivative contracts are
accounted for under <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">mark-to-market</FONT></FONT> accounting, we expect continued volatility in gains and losses on
<FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">mark-to-market</FONT></FONT> derivative contracts in our consolidated statement of operations as changes occur in the NYMEX price indices. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our financial results depend on many factors, particularly the price of natural gas and crude oil and our ability to market our production on
economically attractive terms. Commodity prices are affected by many factors outside of our control, including changes in market supply and demand, which are impacted by weather conditions, pipeline capacity constraints, inventory storage levels,
basis differentials and other factors. In addition, our realized prices are further impacted by our derivative and hedging activities. As a result, we cannot accurately predict future commodity prices and, therefore, we cannot determine with any
degree of certainty what effect increases or decreases in these prices will have on our capital program, production volumes or revenues. Location differentials have increased in certain regions, such as in the Appalachian region, resulting in
further declines in natural gas prices. We expect natural gas and crude oil prices to remain volatile. In addition to production volumes and commodity prices, finding and developing sufficient amounts of natural gas and crude oil reserves at
economical costs are critical to our long-term success. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><U>Critical Accounting Estimates: </U></B></P>

and gas reserves directly impact financial accounting estimates, including depreciation, depletion and amortization. Proved reserves represent estimated quantities of natural gas, crude oil, condensate, and natural gas liquids that geological and
engineering data demonstrate, with reasonable certainty, to be recoverable in future years from known reservoirs under economic and operating conditions existing at the time the estimates were made. The process of estimating quantities of proved oil
and gas reserves is very complex, requiring significant subjective decisions in the evaluation of all available geological, engineering and economic data for each reservoir. The data for a given reservoir may also change substantially over time as a
result of numerous factors including, but not limited to, additional development activity, evolving production history and continual reassessment of the viability of production under varying economic conditions. Consequently, material revisions
(upward or downward) to existing reserve estimates may occur from time to time. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Depreciation, Depletion and Amortization for Oil and Gas Properties
</B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The quantities of estimated proved oil and gas reserves are a significant component of our calculation of depletion expense and
revisions in such estimates may alter the rate of future expense. Holding all other factors constant, if reserves were revised upward or downward, earnings would increase or decrease respectively. Depreciation, depletion and amortization of the cost
of proved oil and gas properties are calculated using the <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">unit-of-production</FONT></FONT> method. The reserve base used to calculate depletion, depreciation or amortization is the

compared to $11.0&nbsp;million in the prior year.&nbsp;Excluding the effects of significant unforeseen expenses or other income, our cash flow from operations fluctuates primarily because of variations in oil and gas production and prices or changes
in working capital accounts. Our oil and gas production will vary based on actual well performance but may be curtailed due to factors beyond our control. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our realized oil and gas prices vary due to world political events, supply and demand of products, product storage levels, and weather
patterns. We sell the majority of our production at spot market prices. Accordingly, product price volatility will affect our cash flow from operations. To mitigate price volatility, we sometimes lock in prices for some portion of our production
through the use of derivatives. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">If our exploratory drilling results in significant new discoveries, we will have to expend additional
capital to finance the completion, development, and potential additional opportunities generated by our success. We believe that, because of the additional reserves resulting from the successful wells and our record of reserve growth in recent
years, we will be able to access sufficient additional capital through bank financing. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Maintaining a strong balance sheet and ample
liquidity are key components of our business strategy. For 2018, we will continue our focus on preserving financial flexibility and ample liquidity as we manage the risks facing our industry. Our 2018 capital budget is reflective of commodity prices
and has been established based on an expectation of available cash flows, with any cash flow deficiencies expected to be funded by borrowings under our revolving credit facility. As we have done historically to preserve or enhance liquidity we may
adjust our capital program throughout the year, divest assets, or enter into strategic joint ventures. We are actively in discussions with financial partners for funding to develop our asset base and, if required, pay down our revolving credit
facility should our borrowing base become limited due to the deterioration of commodity prices. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company maintains a Credit Agreement
with a maturity date of February&nbsp;15, 2021, providing for a credit facility totaling $300&nbsp;million, with a borrowing base of $85&nbsp;million. As of March&nbsp;31, 2018 the Company has $62.5&nbsp;million in outstanding borrowings and
$22.5&nbsp;million in availability under this facility. The bank reviews the borrowing base semi-annually and, at their discretion, may decrease or propose an increase to the borrowing base relative to a
<FONT STYLE="white-space:nowrap">re-determined</FONT> estimate of proved oil and gas reserves. The next borrowing base review is scheduled for June 2018. Our oil and gas properties are pledged as collateral for the line of credit and we are subject
to certain financial and operational covenants defined in the agreement. We are currently in compliance with these covenants and expect to be in compliance over the next twelve months. If we do not comply with these covenants on a continuing basis,
the lenders have the right to refuse to advance additional funds under the facility and/or declare all principal and interest immediately due and payable. Our borrowing base may decrease as a result of lower natural gas or oil prices, operating
difficulties, declines in reserves, lending requirements or regulations, the issuance of new indebtedness or for other reasons set forth in our revolving credit agreement. In the event of a decrease in our borrowing base due to declines in commodity
prices or otherwise, our ability to borrow under our revolving credit facility may be limited and we could be required to repay any indebtedness in excess of the <FONT STYLE="white-space:nowrap">re-determined</FONT> borrowing base. </P>

balanced portfolio of drilling prospects that includes lower risk wells with a high probability of success and higher risk wells with greater economic potential. Based upon the results of horizontal wells drilled by us and other offsetting operators
and historical vertical well performance, we decided in 2016 to reduce the number of vertical wells in our drilling program and drill primarily horizontal wells. We believe horizontal development of our resource base provides superior returns
relative to vertical drilling by accessing a larger base of reserves in each target pay zone with a lateral wellbore. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In accordance with
SEC rules governing the scheduling of the drilling of PUD reserves we have only included in our <FONT STYLE="white-space:nowrap">year-end</FONT> reserve report the 22 PUD locations for which we have definitive plans to drill. The Company has a
working interest in eight of these PUD locations and an overriding royalty interest only in the remaining fourteen locations. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Since the
start of our West Texas horizontal drilling program in 2015 the Company has participated in 56&nbsp;horizontal wells in West Texas. In 39 of these wells, the Company owns an average of 22% working interest. All 39&nbsp;wells are on production. As to
14 wells of the 56 total, the Company participated with less than 1% working interest. Of these 14 wells, seven are on line, and seven are drilled, fracture stimulated, and are being prepared to be put on production. During 2017, the Company
expended approximately $49.5 million in this program. Development of our West Texas resource has continued in the first quarter of 2018 with the drilling of three horizontal wells. As of March&nbsp;31, 2018, these three wells have been drilled and
are being prepared for hydraulic fracture stimulation. We also anticipate the drilling of an additional 8 wells in 2018, although AFEs and specific plans for drilling have not been finalized. This additional activity brings the anticipated total to
11 horizontal wells drilled in 2018 in our West Texas horizontal drilling program. In addition, the Company is participating for less than 1% interest in seven other horizontal wells that are in the process of being put on production. </P>

were drilled and completed in 2017 at a gross cost of $106,267,000. The Company invested a net $43.3&nbsp;million with an average 34.8% interest. In the first quarter of 2018, an additional three wells have been drilled and are in the process of
being completed at an expected gross cost of $25,441,000. We have a 38.25% interest in these wells and our expected net cost will be approximate $9,371,000. Apache Corporation has indicated plans to continue to PAD drill the acreage and future
phases of the development are expected to result in approximately 40 additional horizontal wells being drilled at a cost of about $312&nbsp;million. The Company owns various interests ranging from 14% to 49% in the lands to be developed in this
project and expect our share of these capital expenditures to be approximately $80&nbsp;million. The actual number of wells drilled, the cost, and the timing of drilling may vary based upon commodity market conditions. Apache&#146;s drilling plans
indicate an additional eight wells will be drilled later this year at a cost of $50&nbsp;million, of which our share is approximately $24&nbsp;million. These wells meet the definition of proved undeveloped reserves, however, they were not included

approximately $27&nbsp;million through <FONT STYLE="white-space:nowrap">year-end</FONT> 2017. Over this same time period the Company chose to retain an overriding royalty interest in 28 other horizontal wells that were drilled. The Company is
currently participating in two horizontal wells operated by Linn Operating Inc. in Grady County, Oklahoma. We are participating for 10% interest in one well and 1% interest in the other. The anticipated cost for these wells is $14,703,000, with our
net share being $828,000. Both wells have been drilled and are waiting on fracture stimulation. In addition, the Company has elected to retain an ORRI in 16 wells that are in the process of being drilled or completed in various Counties of central
Oklahoma. Also, in 2018, the Company anticipates participating in the drilling of as many as five additional horizontal wells in central Oklahoma with <STRIKE></STRIKE>interest of between 6% and <STRIKE></STRIKE>12%. The horizontal activity on
Company acreage in Oklahoma is primarily focused in Canadian, Grady, Kingfisher and Garvin counties where we have approximately 2,231 net acres. We believe our acreage has significant additional resource potential that could support the drilling of
72&nbsp;new horizontal wells based on an estimate of only two wells per section with our share of the capital expenditure being about $42&nbsp;million at an average 10.5% ownership level. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">During March 2018 and effective January&nbsp;1, 2018, PrimeEnergy agreed to sell its right, title and interest in 3,506 gross mineral acres,
16,000 net mineral acres, in Garfield County, Oklahoma, including 20 producing wells, for approximately $1,600,000. The Company will retain an overriding royalty interest in the oil and gas produced from the properties. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In a separate transaction, which closed March 2018, the Company sold 3,884 gross mineral acres,
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; net mineral acres in Yuma County, Colorado, and Cheyenne County, Kansas, for $175,000. This divestiture includes 54 producing wells. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In 2017, in the U.S. Gulf Coast region of Texas, the Company participated in the drilling of one well and the recompletion of two wells
operated by Unit Petroleum in the Segno field of Polk County, Texas. The Company invested $179,000 with a 2.8% working interest and a 3.77% revenue interest in these wells. All three wells were successful. In 2018, the Company plans to participate
for 2.8% working interest in the recompletion of one well by Unit Petroleum, and has an overriding royalty of 3.87% in another well that is currently being drilled. The Company will also have an overriding royalty interest in an additional well
slated to be drilled in the second quarter of 2018. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">During the first quarter of 2018, the Company completed two transactions acquiring
464 net mineral acres, 53 oil and gas wells with working interests ranging from 16.6% to 33.4% and one commercial salt water disposal well operated by the Company, all located in Reagan County, Texas, for $6,080,000. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">To supplement cash flow and finance our drilling program during 2017, the Company also sold or farmed-out leasehold rights through six
separate transactions, receiving gross proceeds of approximately $46 million. In West Texas we sold approximately 2,096 net mineral acres for $37.4 million, primarily located in Martin County, and in Oklahoma we farmed-out approximately 1,554 net
mineral acres primarily in Canadian County for $8.6 million and will retain an over-riding royalty interest and potential reversionary interests. These sales were of non-cash flowing mineral interests. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As of March&nbsp;2018, the Company has $2.3&nbsp;million outstanding on our equipment financing facilities which are secured by substantially
all of our field service equipment. The majority of our capital spending is discretionary, and the ultimate level of expenditures will be dependent on our assessment of the oil and gas business environment, the number and quality of oil and gas
prospects available, the market for oilfield services, and oil and gas business opportunities in general. </P>

$1.50&nbsp;per share for 2016. This increase was due to increases in oil and gas production and sales compared to 2016 combined with gains related to the sale of acreage. The significant components of net income are discussed below. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>Oil and gas sales</I></B> increased $28.6&nbsp;million, or 74.6% to $66.9&nbsp;million for the year ended December&nbsp;31, 2017 from
$38.3&nbsp;million for the year ended December&nbsp;31, 2016. Crude oil and natural gas sales vary due to changes in volumes of production sold and realized commodity prices. Our realized prices at the well head increased an average of $10.06 per
barrel, or 25.3% on crude oil and increased $0.80 per Mcf, or 31.4% on natural gas during 2017 as compared to 2016. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our crude oil

MMcf for the year ended December&nbsp;31, 2016 to 5,008 MMcf for the year ended December&nbsp;31, 2017. The increase in crude oil and natural gas production volumes are a result of the natural decline of existing properties offset by our continued
drilling success in the West Texas and Oklahoma regions as we place new wells into production. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The following table summarizes the primary

the fair market value of commodity contracts held at the end of a reported period, referred to as mark-to-market adjustments, are recognized as unrealized gains and losses in the accompanying consolidated statements of operations. As oil and natural
gas prices remain volatile, mark-to-market accounting treatment creates volatility in our revenues. For the year ended December&nbsp;31, 2017 we recognized unrealized losses of $1.7&nbsp;million associated with crude oil fixed swaps and gains of
$2.3&nbsp;million associated with natural gas fixed swap contracts due to market fluctuations in natural gas and crude oil futures market prices between January 2017 and December&nbsp;2017. For the year ended December&nbsp;31, 2016, we recognized
unrealized losses of $1.7&nbsp;million associated with crude oil fixed swaps and gains of $1.9&nbsp;million associated with natural gas fixed swap contracts due to market fluctuations in natural gas and crude oil futures market prices between

reflecting increased utilization of the pipeline and capacity upgrades added during the past three years. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><B><I>Lease operating

average interest rate paid on outstanding bank borrowings under its revolving credit facility during 2017 and 2016 were 5.21% and 3.93%, respectively. As of December&nbsp;31, 2017 and 2016, the total outstanding borrowings under its revolving credit

control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected.&nbsp;These inherent limitations include the realities that judgments in
decision-making can be faulty, and that breakdowns can occur because of simple error or mistake.&nbsp;The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no

statements&#148;). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December&nbsp;31, 2017 and 2016, and the results of its operations and its cash flows for each of the
two years in the period ended December&nbsp;31, 2017, in conformity with U.S. generally accepted accounting principles. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Basis for Opinion </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">These financial statements are the responsibility of the Company&#146;s management. Our responsibility is to express an opinion on the Company&#146;s financial
statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (&#147;PCAOB&#148;) and are required to be independent with respect to the Company in accordance with the
U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We conducted our audits in
accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The
Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting, but not for
the purpose of expressing an opinion on the effectiveness of the Company&#146;s internal control over financial reporting. Accordingly, we express no such opinion. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used
and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">PrimeEnergy Corporation (&#147;PEC&#148;), a Delaware corporation, was organized in March 1973 and is engaged in the development, acquisition
and production of oil and natural gas properties. PrimeEnergy Corporation and its subsidiaries are herein referred to as the &#147;Company.&#148; The Company owns leasehold, mineral and royalty interests in producing and <FONT
STYLE="white-space:nowrap">non-producing</FONT> oil and gas properties across the United States, primarily in Oklahoma, Texas and West Virginia. The Company operates over approximately 1,500 active wells and owns
<FONT STYLE="white-space:nowrap">non-operating</FONT> interests in approximately 400 additional wells. Additionally, the Company provides well-servicing support operations, site-preparation and construction services for oil and gas drilling and
reworking operations, both in connection with the Company&#146;s activities and providing contract services for third parties. The Company is publicly traded on the NASDAQ under the symbol &#147;PNRG.&#148; PEC owns Eastern Oil Well Service Company
(&#147;EOWSC&#148;) and EOWS Midland Company (&#147;EMID&#148;) which perform oil and gas field servicing. PEC also owns Prime Operating Company (&#147;POC&#148;), which serves as operator for most of the producing oil and gas properties owned by
the Company and affiliated entities. PrimeEnergy Management Corporation (&#147;PEMC&#148;), a wholly-owned subsidiary, acts as the managing general partner, providing administration, accounting and tax preparation services for 6 limited partnerships
and 2 trusts (collectively, the &#147;Partnerships&#148;). The markets for the Company&#146;s products are highly competitive, as oil and gas are commodity products and prices depend upon numerous factors beyond the control of the Company, such as
economic, political and regulatory developments and competition from alternative energy sources. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><B><I>Consolidation and Presentation:
</I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The consolidated financial statements include the accounts of PrimeEnergy Corporation, its subsidiaries and the Partnerships,
using the full consolidation method for those partnerships which are controlled by the Company. The proportionate consolidation method is used to account for those undivided interests in oil and gas properties owned by the Company as well as
interests held in unincorporated legal entities, such as partnerships,&nbsp;engaged in oil and gas production, which are not controlled by the Company. For those entities which are proportionately consolidated, the proportionate share of each
entity&#146;s assets, liabilities, revenue and expenses is included in the appropriate classifications in the consolidated financial statements. Reserve estimates associated with the proportionately consolidated oil and gas interests are calculated
for each property at the Partnership level, and depletion, depreciation and amortization (&#147;DD&amp;A&#148;) rates are determined at the Partnership level. The Company&#146;s reserve estimates are based on the ownership percentage of Partnership
reserve reports. DD&amp;A expense and evaluation of impairment may differ from the Partnership as the Company&#146;s cost basis for the Partnership interests acquired may be different than the cost basis at the Partnership level for properties
acquired by the Partnership. All significant intercompany balances and transactions are eliminated in preparing the consolidated financial statements. </P>

and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Estimates of oil and gas reserves, as determined by independent petroleum engineers,
are continually subject to revision based on price, production history and other factors. Depletion expense, which is computed based on the units of production method, could be significantly impacted by changes in such estimates. Additionally, U.S.
generally accepted accounting principles require that if the expected future undiscounted cash flows from an asset are less than its carrying cost, that asset must be written down to its fair market value. As the fair market value of an oil and gas
property will usually be significantly less than the total undiscounted future net revenues expected from that asset, slight changes in the estimates used to determine future net revenues from an asset could lead to the necessity of recording a
significant impairment of that asset. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><B><I>Property and Equipment: </I></B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company follows the &#147;successful efforts&#148; method of accounting for its oil and gas properties. Under the successful efforts
method, costs of acquiring undeveloped oil and gas leasehold acreage, including lease bonuses, brokers&#146; fees and other related costs are capitalized. Provisions for impairment of undeveloped oil and gas leases are based on periodic evaluations.
Annual lease rentals and exploration expenses, including geological and geophysical expenses and exploratory dry hole costs, are charged against income as incurred. Costs of drilling and equipping productive wells, including development dry holes
and related production facilities, are capitalized. All other property and equipment are carried at cost. Depreciation and depletion of oil and gas production equipment and properties are determined under the <FONT STYLE="white-space:nowrap"><FONT
STYLE="white-space:nowrap">unit-of-production</FONT></FONT> method based on estimated proved developed recoverable oil and gas reserves. Depreciation of all other equipment is determined under the straight-line method using various rates based on
useful lives generally ranging from 5 to 10 years. The cost of assets and related accumulated depreciation is removed from the accounts when such assets are disposed of, and any related gains or losses are reflected in current earnings. </P>

changes in circumstances indicate that the carrying amounts may not be recovered. If the carrying amounts are not expected to be recovered by undiscounted cash flows, the assets are impaired, and an impairment loss is recorded. The amount of
impairment is based on the estimated fair value of the assets determined by discounting anticipated future net cash flows. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><B><I>Fair

liabilities in financial statements that are already required by U.S. generally accepted accounting principles to be measured at fair value. The guidance defines fair value as the price that would be received to sell an asset or paid to transfer a
liability in an orderly transaction between market participants at the measurement date (exit price). The transaction is based on a hypothetical transaction in the principal or most advantageous market considered from the perspective of the market
participant that holds the asset or owes the liability. </P>

independent, knowledgeable and willing and able to transact would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market
corroborated or generally unobservable. The Company attempts to utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The Company is able to classify fair value balances based on the
observability of those inputs. The guidance establishes a formal fair value hierarchy based on the inputs used to measure fair value. The hierarchy gives the highest priority to Level&nbsp;1 inputs, which consist of unadjusted quoted prices for
identical instruments in active markets. Level&nbsp;2 inputs consist of quoted prices for similar instruments. Level&nbsp;3 valuations are derived from inputs that are significant and unobservable; hence, these valuations have the lowest priority.

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The asset retirement obligation primarily represents the estimated present value of the amount the Company will incur to plug, abandon and
remediate producing properties at the end of their productive lives, in accordance with applicable state laws. The Company determined its asset retirement obligation by calculating the present value of estimated cash flows related to the liability.
The asset retirement obligation is recorded as a liability at its estimated present value at its inception, with an offsetting increase to producing properties. Periodic accretion of discount of the estimated liability is recorded as an expense in
the statement of operations. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><B><I>Income Taxes: </I></B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company follows the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are
recorded for the estimated future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured
using the tax rate in effect for the year in which those temporary differences are expected to turn around. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the year of the enacted rate change. A valuation
allowance is established to reduce deferred tax assets if it is more likely than not that the related tax benefits will not be realized. As of December&nbsp;31, 2017, and 2016, we had no valuation allowance. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company is required to make judgments, including estimating reserves for potential adverse outcomes regarding tax positions that the
Company has taken. The Company accounts for uncertainty in income taxes using a recognition and measurement threshold for tax positions taken or expected to be taken in a tax return. The effective tax rate and the tax basis of assets and liabilities
reflect management&#146;s estimates of the ultimate outcome of various tax uncertainties. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"><B><I>General and Administrative Expenses:

accordance with applicable accounting standards for derivative instruments and hedging activities. Such standards require that applicable derivative instruments be measured at fair market value and recognized as assets or liabilities in the balance
sheet. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation is generally established at the inception of a derivative. For derivatives designated as cash flow hedges
and meeting applicable effectiveness guidelines, changes in fair value, to the extent effective,&nbsp;are recognized in other comprehensive income until the hedged item is recognized in earnings. At December&nbsp;31, 2016, the entire other
comprehensive income amount is comprised of the impact of cash flow hedges. Hedge effectiveness is measured at least quarterly based on the relative changes in fair value between the derivative contract and the hedged item over time. Any change in
fair value of a derivative resulting from ineffectiveness or an excluded component of the gain/loss is recognized immediately in the statement of operations. </P>

plugging and abandonment costs, annual inflation of these costs, the productive life of wells and a risk-adjusted interest rate. Changes in any of these assumptions can result in significant revisions to the estimated asset retirement obligation.
Revisions to the asset retirement obligation are recorded with an offsetting change to producing properties, resulting in prospective changes to depreciation, depletion and amortization expense and accretion of discount. Because of the subjectivity
of assumptions and the relatively long life of most of the Company&#146;s wells, the costs to ultimately retire the wells may vary significantly from previous estimates. During 2017 revisions in estimated liabilities for asset retirement obligations
resulted from increased field costs resulting in shorter productive life of marginal wells and the Company&#146;s acceleration of the schedule for plugging various marginal <FONT STYLE="white-space:nowrap">non-core</FONT> properties. </P>

into law the Tax Cuts and Jobs Act (&#147;2017 Tax Act&#148;). For the year ended December&nbsp;31, 2017, the Company recorded a tax benefit of $20.204 million&nbsp;directly related to the effect of the 2017 Tax Act, based on the remeasurement of
deferred tax assets and liabilities at the lower corporate tax rate. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company has $9.918&nbsp;million in alternative minimum tax
(&#147;AMT&#148;) credits at December&nbsp;31, 2017. Under the 2017 Tax Act, the Company may fully offset any regular tax liability in future years.&nbsp;In addition, a portion of the minimum tax credit which exceeds the regular tax liability is
refundable in future years. The refundable portion is 50% of any excess credit in the years 2018 through 2020 and 100% in 2021. The Company will therefore&nbsp;expect to receive&nbsp;credits against regular tax and refunds of previously paid taxes
in the amount of $9.918&nbsp;million over the next four years. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Company is entitled to percentage depletion on certain of its wells,

are $89&nbsp;thousand in the years 2018 through 2026. Any credits not utilized in a given year due to the allowable credit exceeding the tax liability may be carried forward. No credit may be carried forward past 2026. The value of the credit is
calculated net of the federal income tax effect. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In 2016, the Company paid $75&nbsp;thousand in settlement of an audit of its 2014

in the U.S. federal jurisdiction and various state and local jurisdictions. The 2004, 2005, 2006, 2009 and 2014 federal income tax returns have been audited by the Internal Revenue Service. The 2015 through 2017 returns are currently open for
examination by the IRS. Returns for unexamined earlier years may be examined and adjustments made to the amount of percentage depletion and AMT credit carryforwards flowing from those years into an open tax year, although in general no assessment of
income tax may be made for those years on which the statute has closed. State returns for the years&nbsp;2014 through 2017 remain open for examination by the relevant taxing authorities. </P>

estimates of the Company&#146;s proved reserves were determined by an independent petroleum engineer in accordance with U.S. generally accepted accounting principles. The estimates of proved reserves are inherently imprecise and are continually
subject to revision based on production history, results of additional exploration and development and other factors. Estimated future net revenues were computed by reserves, less estimated future development and production costs based on current
costs. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Proved reserve quantity estimates are subject to numerous uncertainties inherent in the estimation of quantities of proved
reserves and in the projection of future rates of production and the timing of development expenditures. The accuracy of such estimates is a function of the quality of available data and of engineering and geological interpretation and judgment.
Results of subsequent drilling, testing and production may cause either upward or downward revision of previous estimates. Further, the volumes considered to be commercially recoverable fluctuate with changes in prices and operating costs. The
Company emphasizes that proved reserve estimates are inherently imprecise and that estimates of new discoveries are more imprecise than those of currently producing oil and gas properties. Accordingly, these estimates are expected to change as
additional information becomes available in the future. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>3. Results of Operations from Oil and Gas Producing Activities </B></P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The 2017 and 2016 extensions and discoveries reflect the successful drilling activity in the Company&#146;s West Texas and
<FONT STYLE="white-space:nowrap">Mid-Continent</FONT> areas. The Company is employing technologies to establish proved reserves that have been demonstrated to provide consistent results capable of repetition. The technologies and economic data being
used in the estimation of its proved reserves include, but are not limited to, electrical logs, radioactivity logs, geologic maps, production data and well test data. The estimated reserves of wells with sufficient production history are estimated
using appropriate decline curves. Estimated reserves of producing wells with limited production history and for undeveloped locations are estimated using performance data from analogous wells in the area. These wells are considered analogous based
on production performance from the same formation and with similar completion techniques. Future development plans are reflective of the current commodity prices and have been established based on an expectation of available cash flows from
operations and availability under our revolving credit facility. </P>

income attributable to certain leasehold and royalty interests of PrimeEnergy Corporation and 100&nbsp;percent of its Partnership Interests (PrimeEnergy) as of December&nbsp;31, 2017. The subject properties are located in the states of Colorado,
Kansas, Louisiana, Mississippi, Montana, New Mexico, North Dakota, Oklahoma, Pennsylvania, Texas, West Virginia and Wyoming. The reserves and income data were estimated based on the definitions and disclosure guidelines of the United States
Securities and Exchange Commission (SEC) contained in Title 17, Code of Federal Regulations, Modernization of Oil and Gas Reporting, Final Rule released January&nbsp;14, 2009 in the Federal Register (SEC regulations). Our third party study,
completed on February&nbsp;12, 2018 and presented herein, was prepared for public disclosure by PrimeEnergy in filings made with the SEC in accordance with the disclosure requirements set forth in the SEC regulations. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The properties evaluated by Ryder Scott represent 100&nbsp;percent of the total net proved liquid hydrocarbon reserves and 100&nbsp;percent of
the total net proved gas reserves of PrimeEnergy as of December&nbsp;31, 2017. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The estimated reserves and future net income amounts
presented in this report, as of December&nbsp;31, 2017 are related to hydrocarbon prices. The hydrocarbon prices used in the preparation of this report are based on the average prices during the <FONT STYLE="white-space:nowrap">12-month</FONT>
period prior to the &#147;as of date&#148; of this report, determined as the unweighted arithmetic averages of the prices in effect on the <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap"><FONT
STYLE="white-space:nowrap">first-day-of-the-month</FONT></FONT></FONT></FONT> for each month within such period, unless prices were defined by contractual arrangements, as required by the SEC regulations. Actual future prices may vary significantly
from the prices required by SEC regulations; therefore, volumes of reserves actually recovered and the amounts of income actually received may differ significantly from the estimated quantities presented in this report. The results of this study are
summarized as follows. </P> <P STYLE="font-size:12pt;margin-top:0pt;margin-bottom:0pt">&nbsp;</P>

broad categories or methods: (1)&nbsp;performance-based methods; (2)&nbsp;volumetric-based methods; and (3)&nbsp;analogy. These methods may be used individually or in combination by the reserve evaluator in the process of estimating the quantities
of reserves. Reserve evaluators must select the method or combination of methods which in their professional judgment is most appropriate given the nature and amount of reliable geoscience and engineering data available at the time of the estimate,
the established or anticipated performance characteristics of the reservoir being evaluated, and the stage of development or producing maturity of the property. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In many cases, the analysis of the available geoscience and engineering data and the subsequent interpretation of this data may indicate a
range of possible outcomes in an estimate, irrespective of the method selected by the evaluator. When a range in the quantity of reserves is identified, the evaluator must determine the uncertainty associated with the incremental quantities of the
reserves. If the reserve quantities are estimated using the deterministic incremental approach, the uncertainty for each discrete incremental quantity of the reserves is addressed by the reserve category assigned by the evaluator. Therefore, it is
the categorization of reserve quantities as proved, probable and/or possible that addresses the inherent uncertainty in the estimated quantities reported. For proved reserves, uncertainty is defined by the SEC as reasonable certainty wherein the
&#147;quantities actually recovered are much more likely than not to be achieved.&#148; The SEC states that &#147;probable reserves are those additional reserves that are less certain to be recovered than proved reserves but which, together with
proved reserves, are as likely as not to be recovered.&#148; The SEC states that &#147;possible reserves are those additional reserves that are less certain to be recovered than probable reserves and the total quantities ultimately recovered from a
project have a low probability of exceeding proved plus probable plus possible reserves.&#148; All quantities of reserves within the same reserve category must meet the SEC definitions as noted above. </P>

proved reserves for the properties included herein were estimated by performance methods, the volumetric method, analogy, or a combination of methods. Essentially all of the proved producing reserves attributable to producing wells and/or reservoirs
were estimated by performance methods. These performance methods include, but may not be limited to, decline curve analysis and material balance which utilized extrapolations of historical production and pressure data available through December 2017
in those cases where such data were considered to be definitive. The data utilized in this analysis were furnished to Ryder Scott by PrimeEnergy and were considered sufficient for the purpose thereof. </P>

production rates. Under the SEC regulations <FONT STYLE="white-space:nowrap">210.4-10(a)(22)(v)</FONT> and (26), proved reserves must be anticipated to be economically producible from a given date forward based on existing economic conditions
including the prices and costs at which economic producibility from a reservoir is to be determined. While it may reasonably be anticipated that the future prices received for the sale of production and the operating costs and other costs relating

 The asset retirement obligation primarily represents the estimated
 present value of the amount the Company will incur to plug, abandon
 and remediate producing properties at the end of their productive
 lives, in accordance with applicable state laws. The Company
 determined its asset retirement obligation by calculating the
 present value of estimated cash flows related to the liability. The
 asset retirement obligation is recorded as a liability at its
 estimated present value at its inception, with an offsetting
 increase to producing properties. Periodic accretion of discount of
 the estimated liability is recorded as an expense in the statement
 of operations.&lt;/p&gt;

 The Company&amp;#x2019;s liability is determined using significant
 assumptions, including current estimates of plugging and
 abandonment costs, annual inflation of these costs, the productive
 life of wells and a risk-adjusted interest rate. Changes in any of
 these assumptions can result in significant revisions to the
 estimated asset retirement obligation. Revisions to the asset
 retirement obligation are recorded with an offsetting change to
 producing properties, resulting in prospective changes to
 depreciation, depletion and amortization expense and accretion of
 discount. Because of the subjectivity of assumptions and the
 relatively long life of most of the Company&amp;#x2019;s wells, the
 costs to ultimately retire the wells may vary significantly from
 previous estimates. During 2017 revisions in estimated liabilities
 for asset retirement obligations resulted from increased field
 costs resulting in shorter productive life of marginal wells and
 the Company&amp;#x2019;s acceleration of the schedule for plugging
 various marginal &lt;font style="WHITE-SPACE: nowrap"&gt;non-core&lt;/font&gt;
 properties.&lt;/p&gt;

 Basic earnings per share are computed by dividing earnings
 available to common stockholders by the weighted average number of
 common shares outstanding during the period. Diluted earnings per

 The Company, as managing general partner of the affiliated
 Partnerships, is responsible for all Partnership activities,
 including the drilling of development wells and the production and
 sale of oil and gas from productive wells. The Company also
 provides the administration, accounting and tax preparation work
 for the Partnerships, and is liable for all debts and liabilities
 of the affiliated Partnerships, to the extent that the assets of a
 given limited Partnership are not sufficient to satisfy its
 obligations.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 The Company is subject to environmental laws and regulations.
 Management believes that future expenses, before recoveries from
 third parties, if any, will not have a material effect on the
 Company&amp;#x2019;s financial condition. This opinion is based on
 expenses incurred to date for remediation and compliance with laws
 and regulations, which have not been material to the
 Company&amp;#x2019;s results of operations.&lt;/p&gt;
 &lt;p style="font-size:1px;margin-top:12px;margin-bottom:0px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 From time to time, the Company is party to certain legal actions
 arising in the ordinary course of business. While the outcome of
 these events cannot be predicted with certainty, management does
 not expect these matters to have a materially adverse effect on the
 financial position or results of operations of the Company.&lt;/p&gt;

 The FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2014-09,&lt;/font&gt; &lt;i&gt;Revenue from Contracts
 with Customers (Topic 606)&lt;/i&gt;. This ASU supersedes the &lt;i&gt;Revenue
 recognition&lt;/i&gt; requirements in Topic 605, Revenue Recognition and
 industry-specific guidance in Subtopic &lt;font style="WHITE-SPACE: nowrap"&gt;932-605.&lt;/font&gt; &lt;i&gt;Extractivies &amp;#x2013; Oil
 and Gas Revenue Recognition.&lt;/i&gt; The new standard removes
 inconsistencies in existing standards, changes the way companies
 recognize revenue from contracts with customers, and increases
 disclosure requirements. The codification was amended through
 additional ASUs and, as amended, requires companies to recognize
 revenue to depict the transfer of goods or services to customers in
 amounts that reflect the consideration to which the company expects
 to be entitled in exchange for those goods or services. The
 guidance is effective for annual and interim periods beginning
 after December&amp;#xA0;15, 2017. The Company adopted the new standard
 on January&amp;#xA0;1, 2018, utilizing the modified retrospective
 approach. Adoption of this ASU did not have a material impact on
 net earnings. Certain items netted in revenue prior to adoption are
 recorded to expense based on the requirements of the new ASU. The
 Company developed an accounting policy, implemented changes to the
 relevant business processes and the control activities within them,
 and continues to evaluate the disclosure requirements as a result
 of the provisions of this ASU.&lt;/p&gt;

 liability, initially measured at the present value of the lease
 payments. It further requires recognition in the income statement
 of a single lease cost, calculated so that the cost of the lease is
 allocated over the lease term on a generally straight-line basis.
 Finally, it requires classification of all cash payments within
 operating activities in the statement of cash flows. It is
 effective for fiscal years commencing after December&amp;#xA0;15, 2018
 and early adoption is permitted. This ASU will not have a material
 impact on the Company&amp;#x2019;s financial statements and related

 In August 2016, the FASB issued Accounting Standards Update (ASU)
 &lt;font style="WHITE-SPACE: nowrap"&gt;2016-15,&lt;/font&gt; Statement of Cash
 Flows (Topic 230). ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-15&lt;/font&gt; seeks to reduce the existing
 diversity in practice in how certain cash receipts and cash
 payments are presented and classified in the statement of cash
 flows. This update is effective for fiscal years beginning after
 December&amp;#xA0;15, 2017, including interim periods within those
 fiscal years, with early adoption permitted. The Company is
 currently evaluating the provisions of ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-15&lt;/font&gt; and assessing the impact, if
 any, it may have on its statement of consolidated cash flows.&lt;/p&gt;

 Method and Joint Venture (Topic 323), which states that registrants
 should consider additional qualitative disclosures if the impact of
 an issued but not yet adopted ASU is unknown or cannot be
 reasonably estimated and to include a description of the effect of
 the accounting policies that the registrant expects to apply, if
 determined. Transition guidance in certain issued but not yet
 adopted ASUs, including Leases and Revenue Recognition, was also
 updated to reflect this amendment. This guidance is effective
 immediately. The adoption of this guidance had no effect on the

 PrimeEnergy Corporation (&amp;#x201C;PEC&amp;#x201D;), a Delaware
 corporation, was organized in March 1973 and is engaged in the
 development, acquisition and production of oil and natural gas
 properties. PrimeEnergy Corporation and its subsidiaries are herein
 referred to as the &amp;#x201C;Company.&amp;#x201D; The Company owns
 leasehold, mineral and royalty interests in producing and
 &lt;font style="WHITE-SPACE: nowrap"&gt;non-producing&lt;/font&gt; oil and gas
 properties across the United States, primarily in Oklahoma, Texas
 and West Virginia. The Company operates over approximately 1,500
 active wells and owns &lt;font style="WHITE-SPACE: nowrap"&gt;non-operating&lt;/font&gt; interests in
 approximately 400 additional wells. Additionally, the Company
 provides well-servicing support operations, site-preparation and
 construction services for oil and gas drilling and reworking
 operations, both in connection with the Company&amp;#x2019;s activities
 and providing contract services for third parties. The Company is
 publicly traded on the NASDAQ under the symbol &amp;#x201C;PNRG.&amp;#x201D;
 PEC owns Eastern Oil Well Service Company (&amp;#x201C;EOWSC&amp;#x201D;) and
 EOWS Midland Company (&amp;#x201C;EMID&amp;#x201D;) which perform oil and gas
 field servicing. PEC also owns Prime Operating Company
 (&amp;#x201C;POC&amp;#x201D;), which serves as operator for most of the
 producing oil and gas properties owned by the Company and
 affiliated entities. PrimeEnergy Management Corporation
 (&amp;#x201C;PEMC&amp;#x201D;), a wholly-owned subsidiary, acts as the
 managing general partner, providing administration, accounting and
 tax preparation services for 6 limited partnerships and 2 trusts
 (collectively, the &amp;#x201C;Partnerships&amp;#x201D;). The markets for the
 Company&amp;#x2019;s products are highly competitive, as oil and gas are
 commodity products and prices depend upon numerous factors beyond
 the control of the Company, such as economic, political and
 regulatory developments and competition from alternative energy
 sources.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Consolidation and Presentation:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The consolidated financial statements include the accounts of
 PrimeEnergy Corporation, its subsidiaries and the Partnerships,
 using the full consolidation method for those partnerships which
 are controlled by the Company. The proportionate consolidation
 method is used to account for those undivided interests in oil and
 gas properties owned by the Company as well as interests held in
 unincorporated legal entities, such as partnerships,&amp;#xA0;engaged
 in oil and gas production, which are not controlled by the Company.
 For those entities which are proportionately consolidated, the
 proportionate share of each entity&amp;#x2019;s assets, liabilities,
 revenue and expenses is included in the appropriate classifications
 in the consolidated financial statements. Reserve estimates
 associated with the proportionately consolidated oil and gas
 interests are calculated for each property at the Partnership
 level, and depletion, depreciation and amortization
 (&amp;#x201C;DD&amp;amp;A&amp;#x201D;) rates are determined at the Partnership
 level. The Company&amp;#x2019;s reserve estimates are based on the
 ownership percentage of Partnership reserve reports. DD&amp;amp;A
 expense and evaluation of impairment may differ from the
 Partnership as the Company&amp;#x2019;s cost basis for the Partnership
 interests acquired may be different than the cost basis at the
 Partnership level for properties acquired by the Partnership. All
 significant intercompany balances and transactions are eliminated
 in preparing the consolidated financial statements.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 Certain reclassifications have been made to prior year statements
 to conform with the current year presentation. These
 reclassifications have no impact on net income and no material
 impact on any other financial statement captions.&lt;/p&gt;

 Subsequent events have been evaluated through the date that the
 consolidated financial statements were issued. During this period,
 there were no material subsequent items requiring disclosure other

 &lt;b&gt;&lt;i&gt;Use of Estimates:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The preparation of financial statements in conformity with U.S.
 generally accepted accounting principles requires management to
 make estimates and assumptions that affect the reported amounts of
 assets and liabilities and disclosure of contingent assets and
 liabilities at the date of the financial statements and the
 reported amounts of revenues and expenses during the reporting
 period. Actual results could differ from those estimates.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Estimates of oil and gas reserves, as determined by independent
 petroleum engineers, are continually subject to revision based on
 price, production history and other factors. Depletion expense,
 which is computed based on the units of production method, could be
 significantly impacted by changes in such estimates. Additionally,
 U.S. generally accepted accounting principles require that if the
 expected future undiscounted cash flows from an asset are less than
 its carrying cost, that asset must be written down to its fair
 market value. As the fair market value of an oil and gas property
 will usually be significantly less than the total undiscounted
 future net revenues expected from that asset, slight changes in the
 estimates used to determine future net revenues from an asset could
 lead to the necessity of recording a significant impairment of that
 asset.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Property and Equipment:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The Company follows the &amp;#x201C;successful efforts&amp;#x201D; method of
 accounting for its oil and gas properties. Under the successful
 efforts method, costs of acquiring undeveloped oil and gas
 leasehold acreage, including lease bonuses, brokers&amp;#x2019; fees and
 other related costs are capitalized. Provisions for impairment of
 undeveloped oil and gas leases are based on periodic evaluations.
 Annual lease rentals and exploration expenses, including geological
 and geophysical expenses and exploratory dry hole costs, are
 charged against income as incurred. Costs of drilling and equipping
 productive wells, including development dry holes and related
 production facilities, are capitalized. All other property and
 equipment are carried at cost. Depreciation and depletion of oil
 and gas production equipment and properties are determined under
 the &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;unit-of-production&lt;/font&gt;&lt;/font&gt; method based
 on estimated proved developed recoverable oil and gas reserves.
 Depreciation of all other equipment is determined under the
 straight-line method using various rates based on useful lives
 generally ranging from 5 to 10 years. The cost of assets and
 related accumulated depreciation is removed from the accounts when
 such assets are disposed of, and any related gains or losses are
 reflected in current earnings.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Capitalization of Interest:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 Interest costs related to financing major oil and gas projects in
 progress are capitalized until the projects are evaluated or until
 the projects are substantially complete and ready for their
 intended use if the projects are evaluated and successful.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Impairment of Long-Lived Assets:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The Company reviews long-lived assets, including oil and gas
 properties, for impairment whenever events or changes in
 circumstances indicate that the carrying amounts may not be
 recovered. If the carrying amounts are not expected to be recovered
 by undiscounted cash flows, the assets are impaired, and an
 impairment loss is recorded. The amount of impairment is based on
 the estimated fair value of the assets determined by discounting
 anticipated future net cash flows.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Fair Value:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The Company follows the authoritative guidance that establishes a
 formal framework for measuring fair values of assets and
 liabilities in financial statements that are already required by
 U.S. generally accepted accounting principles to be measured at
 fair value. The guidance defines fair value as the price that would
 be received to sell an asset or paid to transfer a liability in an
 orderly transaction between market participants at the measurement
 date (exit price). The transaction is based on a hypothetical
 transaction in the principal or most advantageous market considered
 from the perspective of the market participant that holds the asset
 or owes the liability.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%"&gt;
 The Company utilizes market data or assumptions that market
 participants who are independent, knowledgeable and willing and
 able to transact would use in pricing the asset or liability,
 including assumptions about risk and the risks inherent in the
 inputs to the valuation technique. These inputs can be readily
 observable, market corroborated or generally unobservable. The
 Company attempts to utilize valuation techniques that maximize the
 use of observable inputs and minimize the use of unobservable
 inputs. The Company is able to classify fair value balances based
 on the observability of those inputs. The guidance establishes a
 formal fair value hierarchy based on the inputs used to measure
 fair value. The hierarchy gives the highest priority to
 Level&amp;#xA0;1 inputs, which consist of unadjusted quoted prices for
 identical instruments in active markets. Level&amp;#xA0;2 inputs
 consist of quoted prices for similar instruments. Level&amp;#xA0;3
 valuations are derived from inputs that are significant and
 unobservable; hence, these valuations have the lowest priority.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Asset Retirement Obligation:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The asset retirement obligation primarily represents the estimated
 present value of the amount the Company will incur to plug, abandon
 and remediate producing properties at the end of their productive
 lives, in accordance with applicable state laws. The Company
 determined its asset retirement obligation by calculating the
 present value of estimated cash flows related to the liability. The
 asset retirement obligation is recorded as a liability at its
 estimated present value at its inception, with an offsetting
 increase to producing properties. Periodic accretion of discount of
 the estimated liability is recorded as an expense in the statement
 of operations.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Income Taxes:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The Company follows the asset and liability method of accounting
 for income taxes. Under this method, deferred tax assets and
 liabilities are recorded for the estimated future tax consequences
 attributable to the differences between the financial statement
 carrying amounts of existing assets and liabilities and their
 respective tax basis. Deferred tax assets and liabilities are
 measured using the tax rate in effect for the year in which those
 temporary differences are expected to turn around. The effect of a
 change in tax rates on deferred tax assets and liabilities is
 recognized in the year of the enacted rate change. A valuation
 allowance is established to reduce deferred tax assets if it is
 more likely than not that the related tax benefits will not be
 realized. As of December&amp;#xA0;31, 2017, and 2016, we had no
 valuation allowance.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The Company is required to make judgments, including estimating
 reserves for potential adverse outcomes regarding tax positions
 that the Company has taken. The Company accounts for uncertainty in
 income taxes using a recognition and measurement threshold for tax
 positions taken or expected to be taken in a tax return. The
 effective tax rate and the tax basis of assets and liabilities
 reflect management&amp;#x2019;s estimates of the ultimate outcome of
 various tax uncertainties.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;General and Administrative Expenses:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 General and administrative expenses represent cost and expenses
 associated with the operation of the Company.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Earnings Per Common Share:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 Basic earnings per share are computed by dividing earnings
 available to common stockholders by the weighted average number of
 common shares outstanding during the period. Diluted earnings per
 share reflect per share amounts that would have resulted if
 dilutive potential common stock had been converted to common stock
 in gain periods.&lt;/p&gt;

 For purposes of the consolidated statements of cash flows, the
 Company considers short-term, highly liquid investments with
 original maturities of less than ninety days to be cash
 equivalents.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 18px"&gt;

 The Company maintains significant banking relationships with
 financial institutions in the State of Texas. The Company limits
 its risk by periodically evaluating the relative credit standing of
 these financial institutions. The Company&amp;#x2019;s oil and gas
 production purchasers consist primarily of independent marketers
 and major gas pipeline companies.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;&lt;i&gt;Hedging:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The Company periodically enters into oil and gas financial
 instruments to manage its exposure to oil and gas price volatility.
 The oil and gas reference prices upon which the price hedging
 instruments are based reflect various market indices that have a
 high degree of historical correlation with actual prices received
 by the Company.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The financial instruments are accounted for in accordance with
 applicable accounting standards for derivative instruments and
 hedging activities. Such standards require that applicable
 derivative instruments be measured at fair market value and
 recognized as assets or liabilities in the balance sheet. The
 accounting for changes in the fair value of a derivative depends on
 the intended use of the derivative and the resulting designation is
 generally established at the inception of a derivative. For
 derivatives designated as cash flow hedges and meeting applicable
 effectiveness guidelines, changes in fair value, to the extent
 effective,&amp;#xA0;are recognized in other comprehensive income until
 the hedged item is recognized in earnings. At December&amp;#xA0;31,
 2016, the entire other comprehensive income amount is comprised of
 the impact of cash flow hedges. Hedge effectiveness is measured at
 least quarterly based on the relative changes in fair value between
 the derivative contract and the hedged item over time. Any change
 in fair value of a derivative resulting from ineffectiveness or an
 excluded component of the gain/loss is recognized immediately in
 the statement of operations.&lt;/p&gt;

 The FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2014-09,&lt;/font&gt; &lt;i&gt;Revenue from Contracts

 industry-specific guidance in Subtopic &lt;font style="WHITE-SPACE: nowrap"&gt;932-605.&lt;/font&gt; &lt;i&gt;Extractivies &amp;#x2013; Oil
 and Gas Revenue Recognition.&lt;/i&gt; The new standard removes
 inconsistencies in existing standards, changes the way companies
 recognize revenue from contracts with customers, and increases
 disclosure requirements. The codification was amended through
 additional ASUs and, as amended, requires companies to recognize
 revenue to depict the transfer of goods or services to customers in
 amounts that reflect the consideration to which the company expects
 to be entitled in exchange for those goods or services. The
 guidance is effective for annual and interim periods beginning
 after December&amp;#xA0;15, 2017. The Company adopted the new standard
 on January&amp;#xA0;1, 2018, utilizing the modified retrospective
 approach. Adoption of this ASU did not have a material impact on
 net earnings. Certain items netted in revenue prior to adoption are
 recorded to expense based on the requirements of the new ASU. The
 Company developed an accounting policy, implemented changes to the
 relevant business processes and the control activities within them,
 and continues to evaluate the disclosure requirements as a result
 of the provisions of this ASU.&lt;/p&gt;

 The FASB issued ASU &lt;font style="WHITE-SPACE: nowrap"&gt;2016-02,&lt;/font&gt; &lt;i&gt;Leases (Topic 842&lt;/i&gt;).
 This ASU requires lessee recognition on the balance sheet of a
 &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;right-of-use&lt;/font&gt;&lt;/font&gt; asset and a lease
 liability, initially measured at the present value of the lease
 payments. It further requires recognition in the income statement
 of a single lease cost, calculated so that the cost of the lease is
 allocated over the lease term on a generally straight-line basis.
 Finally, it requires classification of all cash payments within
 operating activities in the statement of cash flows. It is
 effective for fiscal years commencing after December&amp;#xA0;15, 2018
 and early adoption is permitted. This ASU will not have a material
 impact on the Company&amp;#x2019;s financial statements and related

 &lt;b&gt;1. Presentation of Reserve Disclosure Information&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 Reserve disclosure information is presented in accordance with U.S.
 generally accepted accounting principles. The Company&amp;#x2019;s
 reserves include amounts attributable to &lt;font style="WHITE-SPACE: nowrap"&gt;non-controlling&lt;/font&gt; interests in the
 Partnerships. These interests represent less than 10% of the
 Company&amp;#x2019;s reserves.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;2. Determination of Proved Reserves&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The estimates of the Company&amp;#x2019;s proved reserves were
 determined by an independent petroleum engineer in accordance with
 U.S. generally accepted accounting principles. The estimates of
 proved reserves are inherently imprecise and are continually
 subject to revision based on production history, results of
 additional exploration and development and other factors. Estimated
 future net revenues were computed by reserves, less estimated
 future development and production costs based on current costs.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Proved reserve quantity estimates are subject to numerous
 uncertainties inherent in the estimation of quantities of proved
 reserves and in the projection of future rates of production and
 the timing of development expenditures. The accuracy of such
 estimates is a function of the quality of available data and of
 engineering and geological interpretation and judgment. Results of
 subsequent drilling, testing and production may cause either upward
 or downward revision of previous estimates. Further, the volumes
 considered to be commercially recoverable fluctuate with changes in
 prices and operating costs. The Company emphasizes that proved
 reserve estimates are inherently imprecise and that estimates of
 new discoveries are more imprecise than those of currently
 producing oil and gas properties. Accordingly, these estimates are
 expected to change as additional information becomes available in
 the future.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;3. Results of Operations from Oil and Gas Producing
 Activities&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The results of operations from oil and gas producing activities
 were prepared in accordance with U.S. generally accepted accounting
 principles. General and administrative expenses, interest costs and
 other unrelated costs are not deducted in computing results of
 operations from oil and gas activities.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;4. Standardized Measure of Discounted Future Net Cash Flows and
 Changes Therein Relating to Proved Oil and Gas Reserves&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The standardized measure of discounted future net cash flows
 relating to proved oil and gas reserves and the changes of
 standardized measure of discounted future net cash flows relating
 to proved oil and gas reserves were prepared in accordance with
 U.S. generally accepted accounting principles.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Future cash inflows are computed as described in Note 2 by applying
 current prices to &lt;font style="WHITE-SPACE: nowrap"&gt;year-end&lt;/font&gt;
 quantities of proved reserves.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Future production and development costs are computed estimating the
 expenditures to be incurred in developing and producing the oil and
 gas reserves at &lt;font style="WHITE-SPACE: nowrap"&gt;year-end,&lt;/font&gt;
 based on &lt;font style="WHITE-SPACE: nowrap"&gt;year-end&lt;/font&gt; costs
 and assuming continuation of existing economic conditions.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Future income tax expenses are calculated by applying the 2018 U.S.
 tax rate to future &lt;font style="WHITE-SPACE: nowrap"&gt;pre-tax&lt;/font&gt;
 cash inflows relating to proved oil and gas reserves, less the tax
 basis of properties involved. Future income tax expenses give
 effect to permanent differences and tax credits and allowances
 relating to the proved oil and gas reserves.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%"&gt;
 Future net cash flows are discounted at a rate of 10% annually
 (pursuant to applicable guidance) to derive the standardized
 measure of discounted future net cash flows. This calculation does
 not necessarily represent an estimate of fair market value or the
 present value of such cash flows since future prices and costs can
 vary substantially from &lt;font style="WHITE-SPACE: nowrap"&gt;year-end&lt;/font&gt; and the use of a 10% discount
 figure is arbitrary.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 18pt"&gt;
 &lt;b&gt;5. Changes in Reserves&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt"&gt;
 The 2017 and 2016 extensions and discoveries reflect the successful
 drilling activity in the Company&amp;#x2019;s West Texas and
 &lt;font style="WHITE-SPACE: nowrap"&gt;Mid-Continent&lt;/font&gt; areas. The
 Company is employing technologies to establish proved reserves that
 have been demonstrated to provide consistent results capable of
 repetition. The technologies and economic data being used in the
 estimation of its proved reserves include, but are not limited to,
 electrical logs, radioactivity logs, geologic maps, production data
 and well test data. The estimated reserves of wells with sufficient
 production history are estimated using appropriate decline curves.
 Estimated reserves of producing wells with limited production
 history and for undeveloped locations are estimated using
 performance data from analogous wells in the area. These wells are
 considered analogous based on production performance from the same
 formation and with similar completion techniques. Future
 development plans are reflective of the current commodity prices
 and have been established based on an expectation of available cash
 flows from operations and availability under our revolving credit
 facility.&lt;/p&gt;

 The consolidated financial statements include the accounts of
 PrimeEnergy Corporation, its subsidiaries and the Partnerships,
 using the full consolidation method for those partnerships which
 are controlled by the Company. The proportionate consolidation
 method is used to account for those undivided interests in oil and
 gas properties owned by the Company as well as interests held in
 unincorporated legal entities, such as partnerships,&amp;#xA0;engaged
 in oil and gas production, which are not controlled by the Company.
 For those entities which are proportionately consolidated, the
 proportionate share of each entity&amp;#x2019;s assets, liabilities,
 revenue and expenses is included in the appropriate classifications
 in the consolidated financial statements. Reserve estimates
 associated with the proportionately consolidated oil and gas
 interests are calculated for each property at the Partnership
 level, and depletion, depreciation and amortization
 (&amp;#x201C;DD&amp;amp;A&amp;#x201D;) rates are determined at the Partnership
 level. The Company&amp;#x2019;s reserve estimates are based on the
 ownership percentage of Partnership reserve reports. DD&amp;amp;A
 expense and evaluation of impairment may differ from the
 Partnership as the Company&amp;#x2019;s cost basis for the Partnership
 interests acquired may be different than the cost basis at the
 Partnership level for properties acquired by the Partnership. All
 significant intercompany balances and transactions are eliminated
 in preparing the consolidated financial statements.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Fair Value:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 The Company follows the authoritative guidance that establishes a
 formal framework for measuring fair values of assets and
 liabilities in financial statements that are already required by
 U.S. generally accepted accounting principles to be measured at
 fair value. The guidance defines fair value as the price that would
 be received to sell an asset or paid to transfer a liability in an
 orderly transaction between market participants at the measurement
 date (exit price). The transaction is based on a hypothetical
 transaction in the principal or most advantageous market considered
 from the perspective of the market participant that holds the asset
 or owes the liability.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%"&gt;
 The Company utilizes market data or assumptions that market
 participants who are independent, knowledgeable and willing and
 able to transact would use in pricing the asset or liability,
 including assumptions about risk and the risks inherent in the
 inputs to the valuation technique. These inputs can be readily
 observable, market corroborated or generally unobservable. The
 Company attempts to utilize valuation techniques that maximize the
 use of observable inputs and minimize the use of unobservable
 inputs. The Company is able to classify fair value balances based
 on the observability of those inputs. The guidance establishes a
 formal fair value hierarchy based on the inputs used to measure
 fair value. The hierarchy gives the highest priority to
 Level&amp;#xA0;1 inputs, which consist of unadjusted quoted prices for
 identical instruments in active markets. Level&amp;#xA0;2 inputs
 consist of quoted prices for similar instruments. Level&amp;#xA0;3
 valuations are derived from inputs that are significant and
 unobservable; hence, these valuations have the lowest priority.&lt;/p&gt;

 Deferred income taxes reflect the impact of temporary differences
 between the amount of assets and liabilities recognized for
 financial reporting purposes and such amounts recognized for tax
 purposes.&lt;/p&gt;

 On December&amp;#xA0;22, 2017, the U.S. enacted into law the Tax Cuts
 and Jobs Act (&amp;#x201C;2017 Tax Act&amp;#x201D;). For the year ended
 December&amp;#xA0;31, 2017, the Company recorded a tax benefit of
 $20.204 million&amp;#xA0;directly related to the effect of the 2017 Tax
 Act, based on the remeasurement of deferred tax assets and
 liabilities at the lower corporate tax rate.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The Company has $9.918&amp;#xA0;million in alternative minimum tax
 (&amp;#x201C;AMT&amp;#x201D;) credits at December&amp;#xA0;31, 2017. Under the
 2017 Tax Act, the Company may fully offset any regular tax
 liability in future years.&amp;#xA0;In addition, a portion of the
 minimum tax credit which exceeds the regular tax liability is
 refundable in future years. The refundable portion is 50% of any
 excess credit in the years 2018 through 2020 and 100% in 2021. The
 Company will therefore&amp;#xA0;expect to receive&amp;#xA0;credits against
 regular tax and refunds of previously paid taxes in the amount of
 $9.918&amp;#xA0;million over the next four years.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The Company is entitled to percentage depletion on certain of its
 wells, which is calculated without reference to the basis of the
 property. To the extent that such depletion exceeds a
 property&amp;#x2019;s basis, it creates a permanent difference, which
 lowers the Company&amp;#x2019;s effective&amp;#xA0;rate.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The Company is allowed a credit against the Texas Franchise Tax
 based on net operating losses incurred in prior periods. The
 credits allowed are $89&amp;#xA0;thousand in the years 2018 through
 2026. Any credits not utilized in a given year due to the allowable
 credit exceeding the tax liability may be carried forward. No
 credit may be carried forward past 2026. The value of the credit is
 calculated net of the federal income tax effect.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 In 2016, the Company paid $75&amp;#xA0;thousand in settlement of an
 audit of its 2014 federal income tax return.&lt;/p&gt;

 The Company has not recorded any provision for uncertain tax
 positions. The Company files income tax returns in the U.S. federal
 jurisdiction and various state and local jurisdictions. The 2004,
 2005, 2006, 2009 and 2014 federal income tax returns have been
 audited by the Internal Revenue Service. The 2015 through 2017
 returns are currently open for examination by the IRS. Returns for
 unexamined earlier years may be examined and adjustments made to
 the amount of percentage depletion and AMT credit carryforwards
 flowing from those years into an open tax year, although in general
 no assessment of income tax may be made for those years on which
 the statute has closed. State returns for the years&amp;#xA0;2014
 through 2017 remain open for examination by the relevant taxing
 authorities.&lt;/p&gt;

 The preparation of financial statements in conformity with U.S.
 generally accepted accounting principles requires management to
 make estimates and assumptions that affect the reported amounts of
 assets and liabilities and disclosure of contingent assets and
 liabilities at the date of the financial statements and the
 reported amounts of revenues and expenses during the reporting
 period. Actual results could differ from those estimates.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Estimates of oil and gas reserves, as determined by independent
 petroleum engineers, are continually subject to revision based on
 price, production history and other factors. Depletion expense,
 which is computed based on the units of production method, could be
 significantly impacted by changes in such estimates. Additionally,
 U.S. generally accepted accounting principles require that if the
 expected future undiscounted cash flows from an asset are less than
 its carrying cost, that asset must be written down to its fair
 market value. As the fair market value of an oil and gas property
 will usually be significantly less than the total undiscounted
 future net revenues expected from that asset, slight changes in the
 estimates used to determine future net revenues from an asset could
 lead to the necessity of recording a significant impairment of that
 asset.&lt;/p&gt;

 The Company periodically enters into oil and gas financial
 instruments to manage its exposure to oil and gas price volatility.
 The oil and gas reference prices upon which the price hedging
 instruments are based reflect various market indices that have a
 high degree of historical correlation with actual prices received
 by the Company.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: 400; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial"&gt;
 The financial instruments are accounted for in accordance with
 applicable accounting standards for derivative instruments and
 hedging activities. Such standards require that applicable
 derivative instruments be measured at fair market value and
 recognized as assets or liabilities in the balance sheet. The
 accounting for changes in the fair value of a derivative depends on
 the intended use of the derivative and the resulting designation is
 generally established at the inception of a derivative. For
 derivatives designated as cash flow hedges and meeting applicable
 effectiveness guidelines, changes in fair value, to the extent
 effective,&amp;#xA0;are recognized in other comprehensive income until
 the hedged item is recognized in earnings. At December&amp;#xA0;31,
 2016, the entire other comprehensive income amount is comprised of
 the impact of cash flow hedges. Hedge effectiveness is measured at
 least quarterly based on the relative changes in fair value between
 the derivative contract and the hedged item over time. Any change
 in fair value of a derivative resulting from ineffectiveness or an
 excluded component of the gain/loss is recognized immediately in
 the statement of operations.&lt;/p&gt;

 Basic earnings per share are computed by dividing earnings
 available to common stockholders by the weighted average number of
 common shares outstanding during the period. Diluted earnings per
 share reflect per share amounts that would have resulted if
 dilutive potential common stock had been converted to common stock
 in gain periods. The following reconciles amounts reported in the
 financial statements:&lt;/p&gt;

 Authoritative guidance on fair value measurements defines fair
 value, establishes a framework for measuring fair value and
 stipulates the related disclosure requirements. The Company follows
 a three-level hierarchy, prioritizing and defining the types of
 inputs used to measure fair value. The fair values of the
 Company&amp;#x2019;s interest rate swaps, natural gas and crude oil
 price collars and swaps are designated as Level&amp;#xA0;3. The
 following fair value hierarchy table presents information about the
 Company&amp;#x2019;s assets and liabilities measured at fair value on a
 recurring basis at December&amp;#xA0;31, 2017 and December&amp;#xA0;31,

 The derivative contracts were measured based on quotes from the
 Company&amp;#x2019;s counterparties. Such quotes have been derived using
 valuation models that consider various inputs including current
 market and contractual prices for the underlying instruments,
 quoted forward prices for natural gas and crude oil, volatility
 factors and interest rates, such as a LIBOR curve for a similar
 length of time as the derivative contract term as applicable. These
 estimates are verified using comparable NYMEX futures contracts or
 are compared to multiple quotes obtained from counterparties for
 reasonableness.&lt;/p&gt;

 The significant unobservable inputs for Level&amp;#xA0;3 derivative
 contracts include basis differentials and volatility factors. An
 increase (decrease) in these unobservable inputs would result in an
 increase (decrease) in fair value, respectively. The Company does
 not have access to the specific assumptions used in its
 counterparties&amp;#x2019; valuation models. Consequently, additional
 disclosures regarding significant Level&amp;#xA0;3 unobservable inputs
 were not provided.&lt;/p&gt;

 The Company is exposed to commodity price and interest rate risk,
 and management considers periodically the Company&amp;#x2019;s exposure
 to cash flow variability resulting from the commodity price changes
 and interest rate fluctuations. Futures, swaps and options are used
 to manage the Company&amp;#x2019;s exposure to commodity price risk
 inherent in the Company&amp;#x2019;s oil and gas production operations.
 The Company does not apply hedge accounting to any of its
 commodity-based derivatives. Both realized and unrealized gains and
 losses associated with commodity derivative instruments are
 recognized in earnings.&lt;/p&gt;

 Interest rate swap derivatives are treated as cash-flow hedges and
 are used to fix our floating interest rates on existing debt.
 Settlements of the swaps, which began in January 2014 and concluded
 in January 2016, was recognized within interest expense. There were
 no remaining interest rate swaps as of December&amp;#xA0;31, 2017 and
 December&amp;#xA0;31, 2016. The value of interest rate swaps if
 applicable, would be recorded in accumulated other comprehensive
 loss, net of tax.&lt;/p&gt;

 The Company reviews long-lived assets, including oil and gas
 properties, for impairment whenever events or changes in
 circumstances indicate that the carrying amounts may not be
 recovered. If the carrying amounts are not expected to be recovered
 by undiscounted cash flows, the assets are impaired, and an
 impairment loss is recorded. The amount of impairment is based on
 the estimated fair value of the assets determined by discounting
 anticipated future net cash flows.&lt;/p&gt;

 The Company follows the asset and liability method of accounting
 for income taxes. Under this method, deferred tax assets and
 liabilities are recorded for the estimated future tax consequences
 attributable to the differences between the financial statement
 carrying amounts of existing assets and liabilities and their
 respective tax basis. Deferred tax assets and liabilities are
 measured using the tax rate in effect for the year in which those
 temporary differences are expected to turn around. The effect of a
 change in tax rates on deferred tax assets and liabilities is
 recognized in the year of the enacted rate change. A valuation
 allowance is established to reduce deferred tax assets if it is
 more likely than not that the related tax benefits will not be
 realized. As of December&amp;#xA0;31, 2017, and 2016, we had no
 valuation allowance.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The Company is required to make judgments, including estimating
 reserves for potential adverse outcomes regarding tax positions
 that the Company has taken. The Company accounts for uncertainty in
 income taxes using a recognition and measurement threshold for tax
 positions taken or expected to be taken in a tax return. The
 effective tax rate and the tax basis of assets and liabilities
 reflect management&amp;#x2019;s estimates of the ultimate outcome of
 various tax uncertainties.&lt;/p&gt;

 Effective July&amp;#xA0;30, 2010 the Company entered into a Second
 Amended and Restated Credit Agreement between Compass Bank as agent
 and a syndicated group of lenders (&amp;#x201C;Credit Agreement&amp;#x201D;).
 The Credit Agreement had a revolving line of credit and letter of
 credit facility of up to $250&amp;#xA0;million with a final maturity
 date of July&amp;#xA0;30, 2017. The credit facility was secured by
 substantially all of the Company&amp;#x2019;s oil and gas properties.
 The credit facility was subject to a borrowing base determined by
 the lenders taking into consideration the estimated value of
 PEC&amp;#x2019;s oil and gas properties in accordance with the
 lenders&amp;#x2019; customary practices for oil and gas loans.&lt;/p&gt;

 2021. The Second Amended and Restated Credit Agreement and
 subsequent amendments were amended and restated by the 2017 Credit
 Agreement. Pursuant to the terms and conditions of the 2017 Credit
 Agreement, the Company has a revolving line of credit and letter of
 credit facility of up to $300&amp;#xA0;million subject to a borrowing
 base that is determined semi-annually by the lenders based upon the
 Company&amp;#x2019;s financial statements and the estimated value of the
 Company&amp;#x2019;s oil and gas properties, in accordance with the
 Lenders&amp;#x2019; customary practices for oil and gas loans. The
 credit facility is secured by substantially all of the
 Company&amp;#x2019;s oil and gas properties. The 2017 Credit Agreement
 includes terms and covenants that require the Company to maintain a
 minimum current ratio, total indebtedness to EBITDAX (earnings
 before depreciation, depletion, amortization, taxes, interest
 expense and exploration costs) ratio and interest coverage ratio,
 as defined, and restrictions are placed on the payment of
 dividends, the amount of treasury stock the Company may purchase,
 commodity hedge agreements, and loans and investments in its
 consolidated subsidiaries and limited partnerships.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 On December&amp;#xA0;22, 2017, the Company and its lenders entered into
 a First Amendment to the Third Amended and Restated Credit
 Agreement. The credit agreement includes the addition of a new
 lender and retains all other aspects of the original credit
 agreement. As of the effective date of this amendment the
 Company&amp;#x2019;s borrowing base was increased to
 $85&amp;#xA0;million.&lt;/p&gt;
 &lt;p style="font-size:1px;margin-top:12px;margin-bottom:0px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 At December&amp;#xA0;31, 2017, the Company had a total of
 $47.7&amp;#xA0;million of borrowings outstanding under its revolving
 credit facility at a weighted-average interest rate of 5.21% and
 $37.3&amp;#xA0;million available for future borrowings. The combined
 weighted average interest rate paid on outstanding bank borrowings
 subject to base rate and LIBO interest was 4.97% for the year ended
 December&amp;#xA0;31, 2017 as compared to 3.93% for year ended
 December&amp;#xA0;31, 2016. The Company&amp;#x2019;s borrowings under this
 credit facility approximates fair value because the interest rates
 are variable and reflective of market rates.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 The Company entered into interest rate hedge agreements to help
 manage interest rate exposure. These contracts include interest
 rate swaps. Interest rate swap transactions generally involve the
 exchange of fixed and floating rate interest payment obligations
 without the exchange of the underlying principal amounts. In July
 2012, the Company entered into interest swap agreements for a
 period of two years, which commenced in January 2014, related to
 $75&amp;#xA0;million of the Company&amp;#x2019;s bank debt resulting in a
 LIBO fixed rate of 0.563% and terminated in January 2016. The
 Company recorded interest expense and paid $7,000 related to the
 settlement of interest rate swaps for the twelve months ended
 December&amp;#xA0;31, 2016.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; margin-left:4%; font-size:10pt; font-family:Times New Roman"&gt;
 &lt;b&gt;&lt;i&gt;Equipment Loans:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 On July&amp;#xA0;31, 2013, the Company entered into a
 $10.0&amp;#xA0;million Loan and Security Agreement with JP Morgan Chase
 Bank (&amp;#x201C;Equipment Loan&amp;#x201D;). The Equipment Loan is secured
 by a portion of the Company&amp;#x2019;s field service equipment,
 carries an interest rate of 3.95%&amp;#xA0;per annum, requires monthly
 payments (principal and interest) of $184,000, and has a final
 maturity date of July&amp;#xA0;31, 2018. As of December&amp;#xA0;31, 2017,
 the Company had a total of $1.267&amp;#xA0;million outstanding on this
 Equipment Loan.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 On July&amp;#xA0;29, 2014, the Company entered into additional
 equipment financing facilities (&amp;#x201C;Additional Equipment
 Loans&amp;#x201D;) totaling $6.0&amp;#xA0;million with JP Morgan Chase Bank.
 In August 2014, the Company drew down $4.8&amp;#xA0;million of this
 facility that is secured by field service equipment, carries an
 interest rate of 3.40%&amp;#xA0;per annum, requires monthly payments
 (principal and interest) of $87,800, and has a final maturity date
 of July&amp;#xA0;31, 2019. The remaining $1.2&amp;#xA0;million under the
 Additional Equipment Loans was available for interim draws to
 finance the acquisition of any future field service equipment. In
 December 2014, the Company made an interim draw of an additional
 $0.5&amp;#xA0;million on this facility that is secured by recently
 purchased field service equipment. Interim draws on this facility
 carried a floating interest rate, payable monthly at the LIBO
 published rate plus 2.50% and on June&amp;#xA0;26, 2015 converted into
 a fixed term loan, with a rate of 3.50% and requiring monthly
 payments (principal and interest) of $8,700 with a final maturity
 date of June&amp;#xA0;26, 2020. As of December&amp;#xA0;31, 2017, the
 Company had a total of $1.870&amp;#xA0;million outstanding on the
 Additional Equipment Loans.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 On January&amp;#xA0;12, 2018, the Company made a principal payment
 towards the third interim loan in the amount of $20,858. Effective
 with the payment due of January&amp;#xA0;26, 2018 the required monthly
 payments (principal and interest) on this loan changed to $7,986
 with a continuing effective rate of 3.50% and a final maturity of
 June&amp;#xA0;26, 2020.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 The Company determined these loans are Level&amp;#xA0;3 liabilities in
 the fair-value hierarchy and estimated their fair value as
 $3,110&amp;#xA0;million and $6,147&amp;#xA0;million at December&amp;#xA0;31,
 2017 and 2016, respectively, using a discounted cash flow
 model.&lt;/p&gt;

 &lt;b&gt;2. Acquisitions and Dispositions&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%"&gt;
 Historically, the Company has repurchased the &lt;font style="WHITE-SPACE: nowrap"&gt;non-controlling&lt;/font&gt; interests of the
 partners and trust unit holders in certain of the Partnerships,
 which consist primarily of oil and gas interests. The Company
 purchased such &lt;font style="WHITE-SPACE: nowrap"&gt;non-controlling&lt;/font&gt; interests in an amount
 totaling $308,000 in 2017 and $224,000 in 2016.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 In May of 2017, we acquired 118 net mineral acres in one and a half
 sections in Upton County, Texas for $596,600 directly offsetting
 Company acreage. This purchase increased Prime&amp;#x2019;s leasehold in
 a core area of expected future development. During the first
 quarter of 2018, the Company acquired 1,640 gross (464 net) mineral
 acres, along with 16.6% to 33.4% working interest ownership in 53
 oil and gas wells and one commercial salt water disposal well
 operated by the Company, all located in Reagan County, Texas, for
 $6,080,000.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 During 2017 the Company also sold or farmed-out leasehold rights
 through six separate transactions, receiving gross proceeds of
 approximately $46 million. In West Texas we sold approximately
 2,096 net mineral acres for $37.4 million, primarily located in
 Martin County, and in Oklahoma we farmed-out approximately 1,554
 net mineral acres primarily in Canadian County for $8.6 million and
 will retain an over-riding royalty interest and potential
 reversionary interests. These sales were of non-cash flowing
 mineral interests.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 The Company has entered into agreements and closed on the sale of
 additional &lt;font style="WHITE-SPACE: nowrap"&gt;non-core&lt;/font&gt;
 acreage and properties for proceeds of approximately
 $1.8&amp;#xA0;million during the first quarter of 2018.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 During 2016, the Company sold or farmed out interests in certain
 non-core undeveloped oil and natural gas properties through a
 number of separate, individually negotiated transactions in
 exchange for cash and a royalty or working interest in both West
 Texas and Oklahoma. Proceeds under these agreements were $34.4
 million.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Property and Equipment:&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;

 The Company follows the &amp;#x201C;successful efforts&amp;#x201D; method of
 accounting for its oil and gas properties. Under the successful
 efforts method, costs of acquiring undeveloped oil and gas
 leasehold acreage, including lease bonuses, brokers&amp;#x2019; fees and
 other related costs are capitalized. Provisions for impairment of
 undeveloped oil and gas leases are based on periodic evaluations.
 Annual lease rentals and exploration expenses, including geological
 and geophysical expenses and exploratory dry hole costs, are
 charged against income as incurred. Costs of drilling and equipping
 productive wells, including development dry holes and related
 production facilities, are capitalized. All other property and
 equipment are carried at cost. Depreciation and depletion of oil
 and gas production equipment and properties are determined under
 the &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;unit-of-production&lt;/font&gt;&lt;/font&gt; method based
 on estimated proved developed recoverable oil and gas reserves.
 Depreciation of all other equipment is determined under the
 straight-line method using various rates based on useful lives
 generally ranging from 5 to 10 years. The cost of assets and
 related accumulated depreciation is removed from the accounts when
 such assets are disposed of, and any related gains or losses are
 reflected in current earnings.&lt;/p&gt;

 &lt;p style="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 The Company, as managing general partner or managing trustee, makes
 an annual offer to repurchase the interests of the partners and
 trust unit holders in certain of the Partnerships or Trusts. The
 Company purchased such interests in an amount totaling $308,000
 during 2017 and $224,000 during 2016.&lt;/p&gt;
 &lt;p style="font-size:1px;margin-top:12px;margin-bottom:0px"&gt;

 &lt;p style="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 Treasury stock purchases in any reported period may include shares
 from a related party, which may include members of the
 Company&amp;#x2019;s Board of Directors. In 2017 and 2016, the Company
 purchased 10,000 shares from a related party.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 Receivables from related parties consist of reimbursable general
 and administrative costs, lease operating expenses and
 reimbursement for property development and related costs. These
 receivables are due from joint venture partners, which may include
 members of the Company&amp;#x2019;s Board of Directors.&lt;/p&gt;
 &lt;p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"&gt;
 Payables owed to related parties primarily represent receipts
 collected by the Company as agent for the joint venture partners,
 which may include members of the Company&amp;#x2019;s Board of
 Directors, for oil and gas sales net of expenses.&lt;/p&gt;

 The estimates of the Company&amp;#x2019;s proved reserves were
 determined by an independent petroleum engineer in accordance with
 U.S. generally accepted accounting principles. The estimates of
 proved reserves are inherently imprecise and are continually
 subject to revision based on production history, results of
 additional exploration and development and other factors. Estimated
 future net revenues were computed by reserves, less estimated
 future development and production costs based on current costs.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%"&gt;
 Proved reserve quantity estimates are subject to numerous
 uncertainties inherent in the estimation of quantities of proved
 reserves and in the projection of future rates of production and
 the timing of development expenditures. The accuracy of such
 estimates is a function of the quality of available data and of
 engineering and geological interpretation and judgment. Results of
 subsequent drilling, testing and production may cause either upward
 or downward revision of previous estimates. Further, the volumes
 considered to be commercially recoverable fluctuate with changes in
 prices and operating costs. The Company emphasizes that proved
 reserve estimates are inherently imprecise and that estimates of
 new discoveries are more imprecise than those of currently
 producing oil and gas properties. Accordingly, these estimates are
 expected to change as additional information becomes available in
 the future.&lt;/p&gt;

 The 2017 and 2016 extensions and discoveries reflect the successful
 drilling activity in the Company&amp;#x2019;s West Texas
 and&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;Mid-Continent&lt;/font&gt;&amp;#xA0;areas.
 The Company is employing technologies to establish proved reserves
 that have been demonstrated to provide consistent results capable
 of repetition. The technologies and economic data being used in the
 estimation of its proved reserves include, but are not limited to,
 electrical logs, radioactivity logs, geologic maps, production data
 and well test data. The estimated reserves of wells with sufficient
 production history are estimated using appropriate decline curves.
 Estimated reserves of producing wells with limited production
 history and for undeveloped locations are estimated using
 performance data from analogous wells in the area. These wells are
 considered analogous based on production performance from the same
 formation and with similar completion techniques. Future
 development plans are reflective of the current commodity prices
 and have been established based on an expectation of available cash
 flows from operations and availability under our revolving credit
 facility.&lt;/p&gt;

 (&amp;#x201C;POC&amp;#x201D;), which serves as operator for most of the
 producing oil and gas properties owned by the Company and
 affiliated entities. PrimeEnergy Management Corporation
 (&amp;#x201C;PEMC&amp;#x201D;), a wholly-owned subsidiary, acts as the
 managing general partner, providing administration, accounting and
 tax preparation services for 6 limited partnerships and 2 trusts
 (collectively, the &amp;#x201C;Partnerships&amp;#x201D;). The markets for the
 Company&amp;#x2019;s products are highly competitive, as oil and gas are
 commodity products and prices depend upon numerous factors beyond
 the control of the Company, such as economic, political and
 regulatory developments and competition from alternative energy
 sources.&lt;/p&gt;

 The standardized measure of discounted future net cash flows
 relating to proved oil and gas reserves and the changes of
 standardized measure of discounted future net cash flows relating
 to proved oil and gas reserves were prepared in accordance with
 U.S. generally accepted accounting principles.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: 400; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial"&gt;
 Future cash inflows are computed as described in Note 2 by applying
 current prices to&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;year-end&lt;/font&gt;&amp;#xA0;quantities
 of proved reserves.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: 400; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial"&gt;
 Future production and development costs are computed estimating the
 expenditures to be incurred in developing and producing the oil and
 gas reserves at&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;year-end,&lt;/font&gt;&amp;#xA0;based
 on&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;year-end&lt;/font&gt;&amp;#xA0;costs and
 assuming continuation of existing economic conditions.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: 400; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial"&gt;
 Future income tax expenses are calculated by applying the 2018 U.S.
 tax rate to future&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;pre-tax&lt;/font&gt;&amp;#xA0;cash inflows
 relating to proved oil and gas reserves, less the tax basis of
 properties involved. Future income tax expenses give effect to
 permanent differences and tax credits and allowances relating to
 the proved oil and gas reserves.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: 400; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 12px; LETTER-SPACING: normal; TEXT-INDENT: 0px; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial"&gt;

 Future net cash flows are discounted at a rate of 10% annually
 (pursuant to applicable guidance) to derive the standardized
 measure of discounted future net cash flows. This calculation does
 not necessarily represent an estimate of fair market value or the
 present value of such cash flows since future prices and costs can
 vary substantially from&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;year-end&lt;/font&gt;&amp;#xA0;and the use
 of a 10% discount figure is arbitrary.&lt;/p&gt;

 PrimeEnergy Corporation (&#x201C;PEC&#x201D;), a Delaware
 corporation, was organized in March 1973 and is engaged in the
 development, acquisition and production of oil and natural gas
 properties. PrimeEnergy Corporation and its subsidiaries are herein
 referred to as the &#x201C;Company.&#x201D; The Company owns
 leasehold, mineral and royalty interests in producing and
 <font style="WHITE-SPACE: nowrap">non-producing</font> oil and gas
 properties across the United States, primarily in Oklahoma, Texas
 and West Virginia. The Company operates over approximately 1,500
 active wells and owns <font style="WHITE-SPACE: nowrap">non-operating</font> interests in
 approximately 400 additional wells. Additionally, the Company
 provides well-servicing support operations, site-preparation and
 construction services for oil and gas drilling and reworking
 operations, both in connection with the Company&#x2019;s activities
 and providing contract services for third parties. The Company is
 publicly traded on the NASDAQ under the symbol &#x201C;PNRG.&#x201D;
 PEC owns Eastern Oil Well Service Company (&#x201C;EOWSC&#x201D;) and
 EOWS Midland Company (&#x201C;EMID&#x201D;) which perform oil and gas
 field servicing. PEC also owns Prime Operating Company
 (&#x201C;POC&#x201D;), which serves as operator for most of the
 producing oil and gas properties owned by the Company and
 affiliated entities. PrimeEnergy Management Corporation
 (&#x201C;PEMC&#x201D;), a wholly-owned subsidiary, acts as the
 managing general partner, providing administration, accounting and
 tax preparation services for 6 limited partnerships and 2 trusts
 (collectively, the &#x201C;Partnerships&#x201D;). The markets for the
 Company&#x2019;s products are highly competitive, as oil and gas are
 commodity products and prices depend upon numerous factors beyond
 the control of the Company, such as economic, political and
 regulatory developments and competition from alternative energy
 sources.</p>

 <b><i>Consolidation and Presentation:</i></b></p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The consolidated financial statements include the accounts of
 PrimeEnergy Corporation, its subsidiaries and the Partnerships,
 using the full consolidation method for those partnerships which
 are controlled by the Company. The proportionate consolidation
 method is used to account for those undivided interests in oil and
 gas properties owned by the Company as well as interests held in
 unincorporated legal entities, such as partnerships,&#xA0;engaged
 in oil and gas production, which are not controlled by the Company.
 For those entities which are proportionately consolidated, the
 proportionate share of each entity&#x2019;s assets, liabilities,
 revenue and expenses is included in the appropriate classifications
 in the consolidated financial statements. Reserve estimates
 associated with the proportionately consolidated oil and gas
 interests are calculated for each property at the Partnership
 level, and depletion, depreciation and amortization
 (&#x201C;DD&amp;A&#x201D;) rates are determined at the Partnership
 level. The Company&#x2019;s reserve estimates are based on the
 ownership percentage of Partnership reserve reports. DD&amp;A
 expense and evaluation of impairment may differ from the
 Partnership as the Company&#x2019;s cost basis for the Partnership
 interests acquired may be different than the cost basis at the
 Partnership level for properties acquired by the Partnership. All
 significant intercompany balances and transactions are eliminated
 in preparing the consolidated financial statements.</p>

 <b><i>Use of Estimates:</i></b></p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The preparation of financial statements in conformity with U.S.
 generally accepted accounting principles requires management to
 make estimates and assumptions that affect the reported amounts of
 assets and liabilities and disclosure of contingent assets and
 liabilities at the date of the financial statements and the
 reported amounts of revenues and expenses during the reporting
 period. Actual results could differ from those estimates.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 Estimates of oil and gas reserves, as determined by independent
 petroleum engineers, are continually subject to revision based on
 price, production history and other factors. Depletion expense,
 which is computed based on the units of production method, could be
 significantly impacted by changes in such estimates. Additionally,
 U.S. generally accepted accounting principles require that if the
 expected future undiscounted cash flows from an asset are less than
 its carrying cost, that asset must be written down to its fair
 market value. As the fair market value of an oil and gas property
 will usually be significantly less than the total undiscounted
 future net revenues expected from that asset, slight changes in the
 estimates used to determine future net revenues from an asset could
 lead to the necessity of recording a significant impairment of that
 asset.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt">
 <b><i>Property and Equipment:</i></b></p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The Company follows the &#x201C;successful efforts&#x201D; method of
 accounting for its oil and gas properties. Under the successful
 efforts method, costs of acquiring undeveloped oil and gas
 leasehold acreage, including lease bonuses, brokers&#x2019; fees and
 other related costs are capitalized. Provisions for impairment of
 undeveloped oil and gas leases are based on periodic evaluations.
 Annual lease rentals and exploration expenses, including geological
 and geophysical expenses and exploratory dry hole costs, are
 charged against income as incurred. Costs of drilling and equipping
 productive wells, including development dry holes and related
 production facilities, are capitalized. All other property and
 equipment are carried at cost. Depreciation and depletion of oil
 and gas production equipment and properties are determined under
 the <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">unit-of-production</font></font> method based
 on estimated proved developed recoverable oil and gas reserves.
 Depreciation of all other equipment is determined under the
 straight-line method using various rates based on useful lives
 generally ranging from 5 to 10 years. The cost of assets and
 related accumulated depreciation is removed from the accounts when
 such assets are disposed of, and any related gains or losses are
 reflected in current earnings.</p>

 <b><i>Capitalization of Interest:</i></b></p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 Interest costs related to financing major oil and gas projects in
 progress are capitalized until the projects are evaluated or until
 the projects are substantially complete and ready for their
 intended use if the projects are evaluated and successful.</p>

 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The Company reviews long-lived assets, including oil and gas
 properties, for impairment whenever events or changes in
 circumstances indicate that the carrying amounts may not be
 recovered. If the carrying amounts are not expected to be recovered
 by undiscounted cash flows, the assets are impaired, and an
 impairment loss is recorded. The amount of impairment is based on
 the estimated fair value of the assets determined by discounting
 anticipated future net cash flows.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt">
 <b><i>Fair Value:</i></b></p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The Company follows the authoritative guidance that establishes a
 formal framework for measuring fair values of assets and
 liabilities in financial statements that are already required by
 U.S. generally accepted accounting principles to be measured at
 fair value. The guidance defines fair value as the price that would
 be received to sell an asset or paid to transfer a liability in an
 orderly transaction between market participants at the measurement
 date (exit price). The transaction is based on a hypothetical
 transaction in the principal or most advantageous market considered
 from the perspective of the market participant that holds the asset
 or owes the liability.</p>
 <p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 12px">
 &#xA0;</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt; TEXT-INDENT: 4%">
 The Company utilizes market data or assumptions that market
 participants who are independent, knowledgeable and willing and
 able to transact would use in pricing the asset or liability,
 including assumptions about risk and the risks inherent in the
 inputs to the valuation technique. These inputs can be readily
 observable, market corroborated or generally unobservable. The
 Company attempts to utilize valuation techniques that maximize the
 use of observable inputs and minimize the use of unobservable
 inputs. The Company is able to classify fair value balances based
 on the observability of those inputs. The guidance establishes a
 formal fair value hierarchy based on the inputs used to measure
 fair value. The hierarchy gives the highest priority to
 Level&#xA0;1 inputs, which consist of unadjusted quoted prices for
 identical instruments in active markets. Level&#xA0;2 inputs
 consist of quoted prices for similar instruments. Level&#xA0;3
 valuations are derived from inputs that are significant and
 unobservable; hence, these valuations have the lowest priority.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt">
 <b><i>Asset Retirement Obligation:</i></b></p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The asset retirement obligation primarily represents the estimated
 present value of the amount the Company will incur to plug, abandon
 and remediate producing properties at the end of their productive
 lives, in accordance with applicable state laws. The Company
 determined its asset retirement obligation by calculating the
 present value of estimated cash flows related to the liability. The
 asset retirement obligation is recorded as a liability at its
 estimated present value at its inception, with an offsetting
 increase to producing properties. Periodic accretion of discount of
 the estimated liability is recorded as an expense in the statement
 of operations.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-LEFT: 4%; MARGIN-TOP: 18pt">
 <b><i>Income Taxes:</i></b></p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt; TEXT-INDENT: 4%">
 The Company follows the asset and liability method of accounting
 for income taxes. Under this method, deferred tax assets and
 liabilities are recorded for the estimated future tax consequences
 attributable to the differences between the financial statement
 carrying amounts of existing assets and liabilities and their
 respective tax basis. Deferred tax assets and liabilities are
 measured using the tax rate in effect for the year in which those
 temporary differences are expected to turn around. The effect of a
 change in tax rates on deferred tax assets and liabilities is
 recognized in the year of the enacted rate change. A valuation
 allowance is established to reduce deferred tax assets if it is
 more likely than not that the related tax benefits will not be

 The Company is required to make judgments, including estimating
 reserves for potential adverse outcomes regarding tax positions
 that the Company has taken. The Company accounts for uncertainty in
 income taxes using a recognition and measurement threshold for tax
 positions taken or expected to be taken in a tax return. The
 effective tax rate and the tax basis of assets and liabilities
 reflect management&#x2019;s estimates of the ultimate outcome of
 various tax uncertainties.</p>

 The Company maintains significant banking relationships with

 The Company periodically enters into oil and gas financial
 instruments to manage its exposure to oil and gas price volatility.
 The oil and gas reference prices upon which the price hedging
 instruments are based reflect various market indices that have a

 by the Company.</p>

 The financial instruments are accounted for in accordance with
 applicable accounting standards for derivative instruments and
 hedging activities. Such standards require that applicable
 derivative instruments be measured at fair market value and
 recognized as assets or liabilities in the balance sheet. The
 accounting for changes in the fair value of a derivative depends on
 the intended use of the derivative and the resulting designation is
 generally established at the inception of a derivative. For
 derivatives designated as cash flow hedges and meeting applicable
 effectiveness guidelines, changes in fair value, to the extent
 effective,&#xA0;are recognized in other comprehensive income until
 the hedged item is recognized in earnings. At December&#xA0;31,
 2016, the entire other comprehensive income amount is comprised of
 the impact of cash flow hedges. Hedge effectiveness is measured at
 least quarterly based on the relative changes in fair value between
 the derivative contract and the hedged item over time. Any change
 in fair value of a derivative resulting from ineffectiveness or an
 excluded component of the gain/loss is recognized immediately in
 the statement of operations.</p>

 The FASB issued ASU <font style="WHITE-SPACE: nowrap">2014-09,</font> <i>Revenue from Contracts
 with Customers (Topic 606)</i>. This ASU supersedes the <i>Revenue
 recognition</i> requirements in Topic 605, Revenue Recognition and
 industry-specific guidance in Subtopic <font style="WHITE-SPACE: nowrap">932-605.</font> <i>Extractivies &#x2013; Oil
 and Gas Revenue Recognition.</i> The new standard removes
 inconsistencies in existing standards, changes the way companies
 recognize revenue from contracts with customers, and increases
 disclosure requirements. The codification was amended through
 additional ASUs and, as amended, requires companies to recognize
 revenue to depict the transfer of goods or services to customers in
 amounts that reflect the consideration to which the company expects
 to be entitled in exchange for those goods or services. The
 guidance is effective for annual and interim periods beginning
 after December&#xA0;15, 2017. The Company adopted the new standard
 on January&#xA0;1, 2018, utilizing the modified retrospective
 approach. Adoption of this ASU did not have a material impact on
 net earnings. Certain items netted in revenue prior to adoption are
 recorded to expense based on the requirements of the new ASU. The
 Company developed an accounting policy, implemented changes to the
 relevant business processes and the control activities within them,
 and continues to evaluate the disclosure requirements as a result
 of the provisions of this ASU.</p>

 The FASB issued ASU <font style="WHITE-SPACE: nowrap">2016-02,</font> <i>Leases (Topic 842</i>).
 This ASU requires lessee recognition on the balance sheet of a
 <font style="WHITE-SPACE: nowrap"><font style="WHITE-SPACE: nowrap">right-of-use</font></font> asset and a lease
 liability, initially measured at the present value of the lease
 payments. It further requires recognition in the income statement
 of a single lease cost, calculated so that the cost of the lease is
 allocated over the lease term on a generally straight-line basis.
 Finally, it requires classification of all cash payments within
 operating activities in the statement of cash flows. It is
 effective for fiscal years commencing after December&#xA0;15, 2018
 and early adoption is permitted. This ASU will not have a material
 impact on the Company&#x2019;s financial statements and related
 disclosures.</p>

 flows. This update is effective for fiscal years beginning after
 December&#xA0;15, 2017, including interim periods within those
 fiscal years, with early adoption permitted. The Company is

 Method and Joint Venture (Topic 323), which states that registrants
 should consider additional qualitative disclosures if the impact of
 an issued but not yet adopted ASU is unknown or cannot be
 reasonably estimated and to include a description of the effect of
 the accounting policies that the registrant expects to apply, if
 determined. Transition guidance in certain issued but not yet
 adopted ASUs, including Leases and Revenue Recognition, was also
 updated to reflect this amendment. This guidance is effective
 immediately. The adoption of this guidance had no effect on the

 Historically, the Company has repurchased the <font style="WHITE-SPACE: nowrap">non-controlling</font> interests of the
 partners and trust unit holders in certain of the Partnerships,
 which consist primarily of oil and gas interests. The Company
 purchased such <font style="WHITE-SPACE: nowrap">non-controlling</font> interests in an amount
 totaling $308,000 in 2017 and $224,000 in 2016.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 In May of 2017, we acquired 118 net mineral acres in one and a half
 sections in Upton County, Texas for $596,600 directly offsetting
 Company acreage. This purchase increased Prime&#x2019;s leasehold in
 a core area of expected future development. During the first
 quarter of 2018, the Company acquired 1,640 gross (464 net) mineral
 acres, along with 16.6% to 33.4% working interest ownership in 53
 oil and gas wells and one commercial salt water disposal well
 operated by the Company, all located in Reagan County, Texas, for
 $6,080,000.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 During 2017 the Company also sold or farmed-out leasehold rights
 through six separate transactions, receiving gross proceeds of
 approximately $46 million. In West Texas we sold approximately
 2,096 net mineral acres for $37.4 million, primarily located in
 Martin County, and in Oklahoma we farmed-out approximately 1,554
 net mineral acres primarily in Canadian County for $8.6 million and
 will retain an over-riding royalty interest and potential
 reversionary interests. These sales were of non-cash flowing
 mineral interests.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 The Company has entered into agreements and closed on the sale of
 additional <font style="WHITE-SPACE: nowrap">non-core</font>

 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 During 2016, the Company sold or farmed out interests in certain
 non-core undeveloped oil and natural gas properties through a
 number of separate, individually negotiated transactions in
 exchange for cash and a royalty or working interest in both West
 Texas and Oklahoma. Proceeds under these agreements were $34.4
 million.</p>

 Effective July&#xA0;30, 2010 the Company entered into a Second
 Amended and Restated Credit Agreement between Compass Bank as agent
 and a syndicated group of lenders (&#x201C;Credit Agreement&#x201D;).
 The Credit Agreement had a revolving line of credit and letter of
 credit facility of up to $250&#xA0;million with a final maturity
 date of July&#xA0;30, 2017. The credit facility was secured by
 substantially all of the Company&#x2019;s oil and gas properties.
 The credit facility was subject to a borrowing base determined by
 the lenders taking into consideration the estimated value of
 PEC&#x2019;s oil and gas properties in accordance with the
 lenders&#x2019; customary practices for oil and gas loans.</p>
 <p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">
 On February&#xA0;15, 2017, the Company and its lenders entered into
 a Third Amended and Restated Credit Agreement (the &#x201C;2017
 Credit Agreement&#x201D;) with a maturity date of February&#xA0;15,
 2021. The Second Amended and Restated Credit Agreement and
 subsequent amendments were amended and restated by the 2017 Credit
 Agreement. Pursuant to the terms and conditions of the 2017 Credit
 Agreement, the Company has a revolving line of credit and letter of
 credit facility of up to $300&#xA0;million subject to a borrowing
 base that is determined semi-annually by the lenders based upon the
 Company&#x2019;s financial statements and the estimated value of the
 Company&#x2019;s oil and gas properties, in accordance with the
 Lenders&#x2019; customary practices for oil and gas loans. The
 credit facility is secured by substantially all of the
 Company&#x2019;s oil and gas properties. The 2017 Credit Agreement
 includes terms and covenants that require the Company to maintain a
 minimum current ratio, total indebtedness to EBITDAX (earnings
 before depreciation, depletion, amortization, taxes, interest
 expense and exploration costs) ratio and interest coverage ratio,
 as defined, and restrictions are placed on the payment of
 dividends, the amount of treasury stock the Company may purchase,
 commodity hedge agreements, and loans and investments in its
 consolidated subsidiaries and limited partnerships.</p>
 <p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">
 On December&#xA0;22, 2017, the Company and its lenders entered into
 a First Amendment to the Third Amended and Restated Credit
 Agreement. The credit agreement includes the addition of a new
 lender and retains all other aspects of the original credit
 agreement. As of the effective date of this amendment the
 Company&#x2019;s borrowing base was increased to
 $85&#xA0;million.</p>
 <p style="font-size:1px;margin-top:12px;margin-bottom:0px">
 &#xA0;</p>
 <p style="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">
 At December&#xA0;31, 2017, the Company had a total of
 $47.7&#xA0;million of borrowings outstanding under its revolving
 credit facility at a weighted-average interest rate of 5.21% and
 $37.3&#xA0;million available for future borrowings. The combined
 weighted average interest rate paid on outstanding bank borrowings
 subject to base rate and LIBO interest was 4.97% for the year ended
 December&#xA0;31, 2017 as compared to 3.93% for year ended
 December&#xA0;31, 2016. The Company&#x2019;s borrowings under this
 credit facility approximates fair value because the interest rates
 are variable and reflective of market rates.</p>
 <p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">
 The Company entered into interest rate hedge agreements to help
 manage interest rate exposure. These contracts include interest
 rate swaps. Interest rate swap transactions generally involve the
 exchange of fixed and floating rate interest payment obligations
 without the exchange of the underlying principal amounts. In July
 2012, the Company entered into interest swap agreements for a
 period of two years, which commenced in January 2014, related to
 $75&#xA0;million of the Company&#x2019;s bank debt resulting in a
 LIBO fixed rate of 0.563% and terminated in January 2016. The
 Company recorded interest expense and paid $7,000 related to the
 settlement of interest rate swaps for the twelve months ended
 December&#xA0;31, 2016.</p>

 <b><i>Equipment Loans:</i></b></p>
 <p style="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">
 On July&#xA0;31, 2013, the Company entered into a
 $10.0&#xA0;million Loan and Security Agreement with JP Morgan Chase
 Bank (&#x201C;Equipment Loan&#x201D;). The Equipment Loan is secured
 by a portion of the Company&#x2019;s field service equipment,
 carries an interest rate of 3.95%&#xA0;per annum, requires monthly
 payments (principal and interest) of $184,000, and has a final
 maturity date of July&#xA0;31, 2018. As of December&#xA0;31, 2017,
 the Company had a total of $1.267&#xA0;million outstanding on this
 Equipment Loan.</p>
 <p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">
 On July&#xA0;29, 2014, the Company entered into additional
 equipment financing facilities (&#x201C;Additional Equipment
 Loans&#x201D;) totaling $6.0&#xA0;million with JP Morgan Chase Bank.
 In August 2014, the Company drew down $4.8&#xA0;million of this
 facility that is secured by field service equipment, carries an
 interest rate of 3.40%&#xA0;per annum, requires monthly payments
 (principal and interest) of $87,800, and has a final maturity date
 of July&#xA0;31, 2019. The remaining $1.2&#xA0;million under the
 Additional Equipment Loans was available for interim draws to
 finance the acquisition of any future field service equipment. In
 December 2014, the Company made an interim draw of an additional
 $0.5&#xA0;million on this facility that is secured by recently
 purchased field service equipment. Interim draws on this facility
 carried a floating interest rate, payable monthly at the LIBO
 published rate plus 2.50% and on June&#xA0;26, 2015 converted into
 a fixed term loan, with a rate of 3.50% and requiring monthly
 payments (principal and interest) of $8,700 with a final maturity
 date of June&#xA0;26, 2020. As of December&#xA0;31, 2017, the
 Company had a total of $1.870&#xA0;million outstanding on the
 Additional Equipment Loans.</p>
 <p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">
 On January&#xA0;12, 2018, the Company made a principal payment
 towards the third interim loan in the amount of $20,858. Effective
 with the payment due of January&#xA0;26, 2018 the required monthly
 payments (principal and interest) on this loan changed to $7,986
 with a continuing effective rate of 3.50% and a final maturity of
 June&#xA0;26, 2020.</p>
 <p style="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">
 The Company determined these loans are Level&#xA0;3 liabilities in
 the fair-value hierarchy and estimated their fair value as
 $3,110&#xA0;million and $6,147&#xA0;million at December&#xA0;31,
 2017 and 2016, respectively, using a discounted cash flow
 model.</p>

 The Company&#x2019;s liability is determined using significant
 assumptions, including current estimates of plugging and
 abandonment costs, annual inflation of these costs, the productive
 life of wells and a risk-adjusted interest rate. Changes in any of
 these assumptions can result in significant revisions to the
 estimated asset retirement obligation. Revisions to the asset
 retirement obligation are recorded with an offsetting change to
 producing properties, resulting in prospective changes to
 depreciation, depletion and amortization expense and accretion of
 discount. Because of the subjectivity of assumptions and the
 relatively long life of most of the Company&#x2019;s wells, the
 costs to ultimately retire the wells may vary significantly from
 previous estimates. During 2017 revisions in estimated liabilities
 for asset retirement obligations resulted from increased field
 costs resulting in shorter productive life of marginal wells and
 the Company&#x2019;s acceleration of the schedule for plugging
 various marginal <font style="WHITE-SPACE: nowrap">non-core</font>
 properties.</p>

 Deferred income taxes reflect the impact of temporary differences
 between the amount of assets and liabilities recognized for
 financial reporting purposes and such amounts recognized for tax
 purposes.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 On December&#xA0;22, 2017, the U.S. enacted into law the Tax Cuts
 and Jobs Act (&#x201C;2017 Tax Act&#x201D;). For the year ended
 December&#xA0;31, 2017, the Company recorded a tax benefit of
 $20.204 million&#xA0;directly related to the effect of the 2017 Tax
 Act, based on the remeasurement of deferred tax assets and
 liabilities at the lower corporate tax rate.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 The Company has $9.918&#xA0;million in alternative minimum tax
 (&#x201C;AMT&#x201D;) credits at December&#xA0;31, 2017. Under the
 2017 Tax Act, the Company may fully offset any regular tax
 liability in future years.&#xA0;In addition, a portion of the
 minimum tax credit which exceeds the regular tax liability is
 refundable in future years. The refundable portion is 50% of any
 excess credit in the years 2018 through 2020 and 100% in 2021. The
 Company will therefore&#xA0;expect to receive&#xA0;credits against
 regular tax and refunds of previously paid taxes in the amount of
 $9.918&#xA0;million over the next four years.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 The Company is entitled to percentage depletion on certain of its
 wells, which is calculated without reference to the basis of the
 property. To the extent that such depletion exceeds a
 property&#x2019;s basis, it creates a permanent difference, which
 lowers the Company&#x2019;s effective&#xA0;rate.</p>

 The Company is allowed a credit against the Texas Franchise Tax
 based on net operating losses incurred in prior periods. The
 credits allowed are $89&#xA0;thousand in the years 2018 through
 2026. Any credits not utilized in a given year due to the allowable
 credit exceeding the tax liability may be carried forward. No
 credit may be carried forward past 2026. The value of the credit is
 calculated net of the federal income tax effect.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 In 2016, the Company paid $75&#xA0;thousand in settlement of an

 The Company has not recorded any provision for uncertain tax
 positions. The Company files income tax returns in the U.S. federal
 jurisdiction and various state and local jurisdictions. The 2004,
 2005, 2006, 2009 and 2014 federal income tax returns have been
 audited by the Internal Revenue Service. The 2015 through 2017
 returns are currently open for examination by the IRS. Returns for
 unexamined earlier years may be examined and adjustments made to
 the amount of percentage depletion and AMT credit carryforwards
 flowing from those years into an open tax year, although in general
 no assessment of income tax may be made for those years on which
 the statute has closed. State returns for the years&#xA0;2014
 through 2017 remain open for examination by the relevant taxing
 authorities.</p>

 Authoritative guidance on fair value measurements defines fair
 value, establishes a framework for measuring fair value and
 stipulates the related disclosure requirements. The Company follows
 a three-level hierarchy, prioritizing and defining the types of
 inputs used to measure fair value. The fair values of the
 Company&#x2019;s interest rate swaps, natural gas and crude oil
 price collars and swaps are designated as Level&#xA0;3. The
 following fair value hierarchy table presents information about the
 Company&#x2019;s assets and liabilities measured at fair value on a
 recurring basis at December&#xA0;31, 2017 and December&#xA0;31,
 2016:</p>

 The derivative contracts were measured based on quotes from the
 Company&#x2019;s counterparties. Such quotes have been derived using
 valuation models that consider various inputs including current
 market and contractual prices for the underlying instruments,
 quoted forward prices for natural gas and crude oil, volatility
 factors and interest rates, such as a LIBOR curve for a similar
 length of time as the derivative contract term as applicable. These
 estimates are verified using comparable NYMEX futures contracts or
 are compared to multiple quotes obtained from counterparties for
 reasonableness.</p>

 The significant unobservable inputs for Level&#xA0;3 derivative
 contracts include basis differentials and volatility factors. An
 increase (decrease) in these unobservable inputs would result in an
 increase (decrease) in fair value, respectively. The Company does

 counterparties&#x2019; valuation models. Consequently, additional
 disclosures regarding significant Level&#xA0;3 unobservable inputs

 The Company is exposed to commodity price and interest rate risk,
 and management considers periodically the Company&#x2019;s exposure
 to cash flow variability resulting from the commodity price changes
 and interest rate fluctuations. Futures, swaps and options are used
 to manage the Company&#x2019;s exposure to commodity price risk
 inherent in the Company&#x2019;s oil and gas production operations.
 The Company does not apply hedge accounting to any of its
 commodity-based derivatives. Both realized and unrealized gains and

 Interest rate swap derivatives are treated as cash-flow hedges and
 are used to fix our floating interest rates on existing debt.

 no remaining interest rate swaps as of December&#xA0;31, 2017 and

 The estimates of the Company&#x2019;s proved reserves were
 determined by an independent petroleum engineer in accordance with
 U.S. generally accepted accounting principles. The estimates of
 proved reserves are inherently imprecise and are continually
 subject to revision based on production history, results of
 additional exploration and development and other factors. Estimated
 future net revenues were computed by reserves, less estimated
 future development and production costs based on current costs.</p>
 <p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt; TEXT-INDENT: 4%">
 Proved reserve quantity estimates are subject to numerous
 uncertainties inherent in the estimation of quantities of proved
 reserves and in the projection of future rates of production and
 the timing of development expenditures. The accuracy of such
 estimates is a function of the quality of available data and of
 engineering and geological interpretation and judgment. Results of
 subsequent drilling, testing and production may cause either upward
 or downward revision of previous estimates. Further, the volumes
 considered to be commercially recoverable fluctuate with changes in
 prices and operating costs. The Company emphasizes that proved
 reserve estimates are inherently imprecise and that estimates of
 new discoveries are more imprecise than those of currently
 producing oil and gas properties. Accordingly, these estimates are
 expected to change as additional information becomes available in
 the future.</p>

 estimation of its proved reserves include, but are not limited to,
 electrical logs, radioactivity logs, geologic maps, production data
 and well test data. The estimated reserves of wells with sufficient
 production history are estimated using appropriate decline curves.
 Estimated reserves of producing wells with limited production
 history and for undeveloped locations are estimated using
 performance data from analogous wells in the area. These wells are
 considered analogous based on production performance from the same
 formation and with similar completion techniques. Future
 development plans are reflective of the current commodity prices

 PrimeEnergy Corporation (&#x201C;PEC&#x201D;), a Delaware
 corporation, was organized in March 1973 and is engaged in the
 development, acquisition and production of oil and natural gas
 properties. PrimeEnergy Corporation and its subsidiaries are herein
 referred to as the &#x201C;Company.&#x201D; The Company owns
 leasehold, mineral and royalty interests in producing and
 <font style="WHITE-SPACE: nowrap">non-producing</font> oil and gas
 properties across the United States, primarily in Oklahoma, Texas
 and West Virginia. The Company operates over approximately 1,500
 active wells and owns <font style="WHITE-SPACE: nowrap">non-operating</font> interests in
 approximately 400 additional wells. Additionally, the Company
 provides well-servicing support operations, site-preparation and
 construction services for oil and gas drilling and reworking
 operations, both in connection with the Company&#x2019;s activities
 and providing contract services for third parties. The Company is
 publicly traded on the NASDAQ under the symbol &#x201C;PNRG.&#x201D;
 PEC owns Eastern Oil Well Service Company (&#x201C;EOWSC&#x201D;) and
 EOWS Midland Company (&#x201C;EMID&#x201D;) which perform oil and gas
 field servicing. PEC also owns Prime Operating Company
 (&#x201C;POC&#x201D;), which serves as operator for most of the
 producing oil and gas properties owned by the Company and
 affiliated entities. PrimeEnergy Management Corporation
 (&#x201C;PEMC&#x201D;), a wholly-owned subsidiary, acts as the
 managing general partner, providing administration, accounting and
 tax preparation services for 6 limited partnerships and 2 trusts
 (collectively, the &#x201C;Partnerships&#x201D;). The markets for the
 Company&#x2019;s products are highly competitive, as oil and gas are
 commodity products and prices depend upon numerous factors beyond
 the control of the Company, such as economic, political and
 regulatory developments and competition from alternative energy
 sources.</p>

 The consolidated financial statements include the accounts of
 PrimeEnergy Corporation, its subsidiaries and the Partnerships,
 using the full consolidation method for those partnerships which
 are controlled by the Company. The proportionate consolidation
 method is used to account for those undivided interests in oil and
 gas properties owned by the Company as well as interests held in
 unincorporated legal entities, such as partnerships,&#xA0;engaged
 in oil and gas production, which are not controlled by the Company.
 For those entities which are proportionately consolidated, the
 proportionate share of each entity&#x2019;s assets, liabilities,
 revenue and expenses is included in the appropriate classifications
 in the consolidated financial statements. Reserve estimates
 associated with the proportionately consolidated oil and gas
 interests are calculated for each property at the Partnership
 level, and depletion, depreciation and amortization
 (&#x201C;DD&amp;A&#x201D;) rates are determined at the Partnership
 level. The Company&#x2019;s reserve estimates are based on the
 ownership percentage of Partnership reserve reports. DD&amp;A
 expense and evaluation of impairment may differ from the
 Partnership as the Company&#x2019;s cost basis for the Partnership
 interests acquired may be different than the cost basis at the
 Partnership level for properties acquired by the Partnership. All
 significant intercompany balances and transactions are eliminated
 in preparing the consolidated financial statements.</p>

 The preparation of financial statements in conformity with U.S.

 assets and liabilities and disclosure of contingent assets and
 liabilities at the date of the financial statements and the
 reported amounts of revenues and expenses during the reporting
 period. Actual results could differ from those estimates.</p>

 Estimates of oil and gas reserves, as determined by independent
 petroleum engineers, are continually subject to revision based on
 price, production history and other factors. Depletion expense,
 which is computed based on the units of production method, could be
 significantly impacted by changes in such estimates. Additionally,
 U.S. generally accepted accounting principles require that if the
 expected future undiscounted cash flows from an asset are less than
 its carrying cost, that asset must be written down to its fair
 market value. As the fair market value of an oil and gas property
 will usually be significantly less than the total undiscounted
 future net revenues expected from that asset, slight changes in the
 estimates used to determine future net revenues from an asset could
 lead to the necessity of recording a significant impairment of that
 asset.</p>

 accounting for its oil and gas properties. Under the successful
 efforts method, costs of acquiring undeveloped oil and gas
 leasehold acreage, including lease bonuses, brokers&#x2019; fees and
 other related costs are capitalized. Provisions for impairment of
 undeveloped oil and gas leases are based on periodic evaluations.
 Annual lease rentals and exploration expenses, including geological
 and geophysical expenses and exploratory dry hole costs, are
 charged against income as incurred. Costs of drilling and equipping
 productive wells, including development dry holes and related
 production facilities, are capitalized. All other property and
 equipment are carried at cost. Depreciation and depletion of oil
 and gas production equipment and properties are determined under

 Depreciation of all other equipment is determined under the
 straight-line method using various rates based on useful lives
 generally ranging from 5 to 10 years. The cost of assets and
 related accumulated depreciation is removed from the accounts when
 such assets are disposed of, and any related gains or losses are
 reflected in current earnings.</p>

 The Company follows the authoritative guidance that establishes a
 formal framework for measuring fair values of assets and
 liabilities in financial statements that are already required by
 U.S. generally accepted accounting principles to be measured at
 fair value. The guidance defines fair value as the price that would
 be received to sell an asset or paid to transfer a liability in an
 orderly transaction between market participants at the measurement
 date (exit price). The transaction is based on a hypothetical
 transaction in the principal or most advantageous market considered
 from the perspective of the market participant that holds the asset

 The Company utilizes market data or assumptions that market
 participants who are independent, knowledgeable and willing and
 able to transact would use in pricing the asset or liability,
 including assumptions about risk and the risks inherent in the
 inputs to the valuation technique. These inputs can be readily
 observable, market corroborated or generally unobservable. The
 Company attempts to utilize valuation techniques that maximize the
 use of observable inputs and minimize the use of unobservable
 inputs. The Company is able to classify fair value balances based
 on the observability of those inputs. The guidance establishes a
 formal fair value hierarchy based on the inputs used to measure
 fair value. The hierarchy gives the highest priority to
 Level&#xA0;1 inputs, which consist of unadjusted quoted prices for
 identical instruments in active markets. Level&#xA0;2 inputs

 The asset retirement obligation primarily represents the estimated
 present value of the amount the Company will incur to plug, abandon
 and remediate producing properties at the end of their productive
 lives, in accordance with applicable state laws. The Company
 determined its asset retirement obligation by calculating the
 present value of estimated cash flows related to the liability. The
 asset retirement obligation is recorded as a liability at its
 estimated present value at its inception, with an offsetting
 increase to producing properties. Periodic accretion of discount of
 the estimated liability is recorded as an expense in the statement

 The Company follows the asset and liability method of accounting
 for income taxes. Under this method, deferred tax assets and
 liabilities are recorded for the estimated future tax consequences
 attributable to the differences between the financial statement
 carrying amounts of existing assets and liabilities and their
 respective tax basis. Deferred tax assets and liabilities are
 measured using the tax rate in effect for the year in which those
 temporary differences are expected to turn around. The effect of a
 change in tax rates on deferred tax assets and liabilities is
 recognized in the year of the enacted rate change. A valuation
 allowance is established to reduce deferred tax assets if it is
 more likely than not that the related tax benefits will not be
 realized. As of December&#xA0;31, 2017, and 2016, we had no
 valuation allowance.</p>

 The Company is required to make judgments, including estimating

 effective tax rate and the tax basis of assets and liabilities
 reflect management&#x2019;s estimates of the ultimate outcome of
 various tax uncertainties.</p>

 The financial instruments are accounted for in accordance with
 applicable accounting standards for derivative instruments and
 hedging activities. Such standards require that applicable
 derivative instruments be measured at fair market value and
 recognized as assets or liabilities in the balance sheet. The
 accounting for changes in the fair value of a derivative depends on
 the intended use of the derivative and the resulting designation is
 generally established at the inception of a derivative. For
 derivatives designated as cash flow hedges and meeting applicable
 effectiveness guidelines, changes in fair value, to the extent
 effective,&#xA0;are recognized in other comprehensive income until
 the hedged item is recognized in earnings. At December&#xA0;31,
 2016, the entire other comprehensive income amount is comprised of
 the impact of cash flow hedges. Hedge effectiveness is measured at
 least quarterly based on the relative changes in fair value between
 the derivative contract and the hedged item over time. Any change
 in fair value of a derivative resulting from ineffectiveness or an
 excluded component of the gain/loss is recognized immediately in
 the statement of operations.</p>

 Proved reserve quantity estimates are subject to numerous
 uncertainties inherent in the estimation of quantities of proved
 reserves and in the projection of future rates of production and
 the timing of development expenditures. The accuracy of such
 estimates is a function of the quality of available data and of
 engineering and geological interpretation and judgment. Results of
 subsequent drilling, testing and production may cause either upward
 or downward revision of previous estimates. Further, the volumes
 considered to be commercially recoverable fluctuate with changes in
 prices and operating costs. The Company emphasizes that proved
 reserve estimates are inherently imprecise and that estimates of
 new discoveries are more imprecise than those of currently
 producing oil and gas properties. Accordingly, these estimates are
 expected to change as additional information becomes available in
 the future.</p>

 estimation of its proved reserves include, but are not limited to,
 electrical logs, radioactivity logs, geologic maps, production data
 and well test data. The estimated reserves of wells with sufficient
 production history are estimated using appropriate decline curves.
 Estimated reserves of producing wells with limited production
 history and for undeveloped locations are estimated using
 performance data from analogous wells in the area. These wells are
 considered analogous based on production performance from the same
 formation and with similar completion techniques. Future
 development plans are reflective of the current commodity prices
 and have been established based on an expectation of available cash
