preparation of financial statements in conformity with generally accepted accounting principles in the United States (&#8220;GAAP&#8221;)
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, 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. Significant estimates include oil and natural gas reserves that are used in the calculation of depreciation, depletion, amortization
and impairment of the carrying value of evaluated oil and natural gas properties; realizability of unevaluated properties; production
and commodity price estimates used to record accrued oil and natural gas sales receivables; futures prices of commodities used in the
valuation of commodity derivative contracts; valuation of warrant instruments; valuation of real estate assets held for sale; and the
cost of future asset retirement obligations. The Company evaluates its estimates on an on-going basis and bases its estimates on historical
experience and on various other assumptions the Company believes to be reasonable. Due to inherent uncertainties, including the future
prices of oil and natural gas, these estimates could change in the near term and such changes could be material.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">The
Company&#8217;s revenues are primarily derived from its non-operated interest in the sales of oil and natural gas production. The sales
of oil and natural gas are made under contracts that operators of the wells have negotiated with third-party customers. The Company receives
payment from the sale of oil and natural gas production between one to three months after delivery. At the end of each period when the
performance obligation is satisfied, the variable consideration can be reasonably estimated and amounts due from customers are accrued
in oil and natural gas sales receivable in the consolidated balance sheets. Variances between the Company&#8217;s estimated revenue and
actual payments are recorded in the month the payment is received. Accordingly,
the variable consideration is not constrained. As a non-operator of its oil and natural gas properties, the Company records its share
of the revenues and expenses based upon the information provided by the operators within the revenue statements.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">&#160;</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">The
Company&#8217;s oil and natural gas production is typically sold at delivery points to various purchasers under contract terms that are
common in the oil and natural gas industry. Regardless of the contract type, the terms of these contracts compensate the well operators
for the value of the oil and natural gas at specified prices, and then the well operators remit payment to the Company for its share
in the value of the oil and natural gas sold.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">&#160;</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">During
2020, the Company acquired operated oil and gas producing properties (see Note 2- <i>Acquisitions</i>, above). The Company sells its
oil production at the delivery point specified in the contract and collects an agreed-upon index price, net of pricing differentials.
The purchaser takes custody, title and risk of loss of the oil at the delivery point; therefore, control passes at the delivery point.
The Company recognizes revenue at the net price received when control transfers to the purchaser. Natural gas and natural gas liquid
(&#8220;NGL&#8221;) are sold at the lease location, which is generally when control of the natural gas and NGL transfers to the purchaser,
and revenue is recognized as the amount received from the purchaser.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">The
Company does not disclose the values of unsatisfied performance obligations under its contracts with customers as it applies the practical
exemption in accordance with Accounting Standards Codification (ASC) 606. The exemption applies to variable consideration that is recognized
as control of the product is transferred to the customer. Since each unit of product represents a separate performance obligation, future
volumes are wholly unsatisfied, and disclosure of the transaction price allocated to the remaining performance obligations is not required.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">The
Company reports revenue as the gross amount received from the well operators before taking into account production taxes and transportation
costs. Production taxes are reported separately, and transportation costs are included in lease operating expense in the accompanying
unaudited condensed consolidated statements of operations. The revenue and costs in the consolidated statements of operations were reported
gross for the three and six months ended June 30, 2021 and 2020, as the gross amounts were known.</span></p>

In addition, Patrick E. Duke, a former director of the Company, had shared voting and shared investment power over APEG. The litigation
arose as a result of a vote at the February 25, 2019 board of directors meeting to terminate Mr. Veltri for using Company funds outside
of his authority and for other reasons (the &#8220;Texas Litigation&#8221;). In a separate lawsuit, APEG initiated a shareholder derivative
action in Colorado against Mr. Veltri due to his refusal to recognize the Board&#8217;s decision to terminate him (the &#8220;Colorado
Litigation&#8221;). The Company was named as a nominal defendant in the Colorado Litigation. The Colorado litigation was dismissed in
May 2020 and the Texas Litigation was dismissed in August 2020.

Company has asset retirement obligations (&#8220;AROs&#8221;) associated with the future plugging and abandonment of proved properties.
Initially, the fair value of a liability for an ARO is recorded in the period in which the ARO is incurred with a corresponding increase
in the carrying amount of the related asset. The liability is accreted to its present value each period and the capitalized cost is depleted
over the life of the related asset. If the liability is settled for an amount other than the recorded amount, an adjustment to the full-cost
pool is recognized. The Company had no assets that are restricted for the purpose of settling AROs.</span></p>

the fair value calculation for the ARO there are numerous assumptions and judgments, including the ultimate retirement cost, inflation
factors, credit-adjusted risk-free discount rates, timing of retirement and changes in legal, regulatory, environmental, and political
environments. To the extent future revisions to assumptions and judgments impact the present value of the existing ARO, a corresponding
adjustment is made to the oil and natural gas property balance.</span></p>

allowance on a quarterly basis. As part of our review, we consider positive and negative evidence, including cumulative results in recent
years. Consistent with the position at December 31, 2020, the Company maintains a full valuation allowance recorded against all DTAs.
The Company, therefore, had no recorded DTAs as of June 30, 2021. We anticipate that we will continue to record a valuation allowance

net loss per common share is calculated by dividing net loss attributable to common shareholders by the weighted-average number of common
shares outstanding for the respective period. Diluted net loss per common share is calculated by dividing adjusted net loss by the diluted
weighted average number of common shares outstanding, which includes the effect of potentially dilutive securities. Potentially dilutive
securities for this calculation consist of stock options and warrants, which are measured using the treasury stock method, the conversion
feature of the Series A Preferred Stock prior to redemption, and unvested shares of restricted common stock. When the Company recognizes
a net loss, as was the case for the three and six months ended June 30, 2021 and 2020, all potentially dilutive shares are anti-dilutive
and are consequently excluded from the calculation of dilutive net loss per common share.</span></p>

Company&#8217;s fair value measurements are estimated pursuant to a fair value hierarchy that requires us to maximize the use of observable
inputs and minimize the use of unobservable inputs when measuring fair value. The valuation hierarchy is based upon the transparency
of inputs to the valuation of an asset or liability as of the measurement date, giving highest priority to quoted prices in active markets
(Level 1) and the lowest priority to unobservable data (Level 3). In some cases, the inputs used to measure fair value might fall in
different levels of the fair value hierarchy. The lowest level input that is significant to a fair value measurement in its entirety
determines the applicable level in the fair value hierarchy. Assessing the significance of a particular input to the fair value measurement
in its entirety requires judgment, considering factors specific to the asset or liability, and may affect the valuation of the assets
and liabilities and their placement within the hierarchy level. The three levels of inputs that may be used to measure fair value are
defined as:</span></p>

2 - Observable inputs other than Level 1 that are directly or indirectly observable for the asset or liability, including quoted prices

other observable inputs that can be corroborated by observable market data.</span></p>

discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires
significant management judgment or estimation.</span></p>

warrants contain a dilutive issuance and other provisions that cause the warrants to be accounted for as a liability. Such warrant instruments
are initially recorded and valued as a Level 3 liability and are accounted for at fair value with changes in fair value reported in earnings.
There were no changes in the methodology to value the warrants. The Company worked with a third-party valuation expert to estimate the
value of the warrants at December 31, 2020 using a Black Scholes model, with the following observable and unobservable inputs:</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">U.S. Energy Corp. - is a Wyoming corporation organized
in 1966. We are an independent energy company focused on the acquisition and development of oil and natural gas producing properties in
the continental United States. Our business activities are currently focused in South Texas, the Williston Basin in North Dakota, Lea
County in New Mexico and Converse County in Wyoming.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">We have historically explored for and produced oil
and natural gas through a non-operator business model. As a non-operator, we rely on our operating partners to propose, permit, drill,
complete and produce oil and natural gas wells. Before a well is drilled, the operator provides all oil and natural gas interest owners
in the designated well the opportunity to participate in the drilling and completion costs and revenues of the well on a pro-rata basis.
Our operating partners also produce, transport, market and account for all oil and natural gas production. With recent acquisitions in
2020 of New Horizon Resources, certain FieldPoint Petroleum wells and certain wells in Liberty County, Texas we now operate a small portion
of our production.</p>

to seek additional opportunities in the oil and natural gas sector, including but not limited to further acquisition of assets, participation
with current and new industry partners in their exploration and development projects, acquisition of existing companies, and the purchase
of oil producing assets. In addition, we plan to grow production by performing workovers on operated idle wells acquired in 2020 to return
them back to production.</p>

Environment</b></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">In early March 2020, there was an outbreak of a novel
strain of coronavirus, which causes the infectious disease known as COVID-19, which resulted in a drastic decline in global demand of
certain mineral and energy products including crude oil. As a result of the lower demand caused by the COVID-19 pandemic and the oversupply
of crude oil, spot and future prices of crude oil fell to historic lows during the second quarter of 2020, which remained depressed for
the majority of 2020. Operators in North Dakota&#8217;s Williston Basin responded by significantly decreasing drilling and completion
activity and shutting in or curtailing production from a significant number of producing wells, all of which have since come back online. Lower oil and natural gas prices not only decrease our revenues, but an extended decline in oil or gas prices may materially
and adversely affect our future business, financial position, cash flows, results of operations, liquidity, ability to finance planned
capital expenditures and the oil and natural gas reserves that we can economically produce.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">Additionally, the outbreak of COVID-19 and decreases
in commodity prices resulting from oversupply, government-imposed travel restrictions, and other constraints on economic activity caused
a significant decrease in the demand for oil and has created disruptions and volatility in the global marketplace for oil and gas during
the first quarter of 2020, and continuing through most of 2020, which negatively affected our results of operations and cash
flows during 2020. While demand and commodity prices have recently recovered and are back to pre-pandemic levels, our financial
results may continue to be depressed in future quarters. The extent to which the COVID-19 pandemic impacts our business going forward
will depend on numerous evolving factors we cannot reliably predict, including the duration and scope of the pandemic; governmental,
business, and individuals&#8217; actions in response to the pandemic; the availability and efficacy of vaccines and boosters,
and the willingness of individuals to obtain such vaccines; future virus mutations; and the impact on economic activity including
the possibility of recession or financial market instability. These factors may adversely impact the supply and demand for oil and gas
and our ability to produce and transport oil and gas and perform operations at and on our properties. This uncertainty also affects management&#8217;s
accounting estimates and assumptions, which could result in greater variability in a variety of areas that depend on these estimates
and assumptions, including investments, receivables, and forward-looking guidance.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The preparation of our unaudited condensed consolidated
financial statements in conformity with generally accepted accounting principles in the United States (&#8220;GAAP&#8221;) requires us
to make assumptions and estimates that affect the reported amounts of assets, liabilities, revenues and expenses, as well as the disclosure
of contingent assets and liabilities at the date of our financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results may differ from these estimates under different assumptions or conditions. A summary of our significant
accounting policies is detailed in <i>Part II, Item 7 &#8211; Management&#8217;s Discussion and Analysis of Financial Condition and Results
of Operations </i>of our 2020 Annual Report on Form 10-K filed with the SEC on March 26, 2021 (the &#8220;2020 Annual Report&#8221;)

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The Company&#8217;s results of operations and operating
cash flows are affected by changes in market prices for crude oil and natural gas. To manage a portion of our exposure to price volatility
from producing crude oil, we entered into a crude oil derivative swap contract during the six months ended June 30, 2021, to protect against
price declines in future periods. The Company does not designate commodity derivative contracts as a cash flow hedges and therefore the
contract does not qualify for hedge accounting. Changes in fair value of the swap contract are recorded in the condensed consolidated
statement of operations. The fair value of the swap contract is recorded as either an asset or a liability on the condensed consolidated
balance sheet.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The increase in our oil and gas revenue of $1,467
thousand for the three months ended June 30, 2021, as compared to the three months ended June 30, 2020, was due to an increase in oil
production of 106% and an increase in the realized price received for our oil production of 264%. The increase in oil prices is primarily
due to stronger demand for crude oil on a global basis as the world recovered from government mandated lockdowns which began in
mid-March 2020 in order to reduce the spread of the COVID-19 pandemic. The increase in oil production volumes is primarily the result
of the acquisitions of properties we completed during 2020, and our efforts in the first six months of 2021 to return idle wells to production.
During the three months ended June 30, 2021, we produced 9,472 Bbls of oil from properties acquired in the second half of 2020.
In addition, during the three months ended June 30, 2021, we experienced production increases in our legacy non-operated properties,
primarily in North Dakota as the result of workovers in which we participated. In the comparable period of the prior year, production
declined due to operators, principally in North Dakota, temporarily shutting in production as the result of low commodity prices.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For the three months ended June 30, 2021, we produced
32,073 BOE, or an average of 356 BOE per day, as compared to 13,897 BOE or 153 BOE per day during the comparable period in 2020. During
the three months ended June 30, 2021, our BOE production mix was 75% oil and 25% natural gas compared to 84% oil and 16% gas in the comparable
period of 2020. The increase in gas as a percentage of total production increased due to the acquisition of non-operated gas producing
properties in the second half of 2020.</p>

taxes increased by $118 thousand, or 908%, compared to the comparable period in 2020. This increase was attributable to the increase in

$445 thousand during the three-month period ended June 30, 2021, as compared to the prior year period. The increase was primarily attributable
to an increase in professional fees of $331 thousand. Professional fees incurred during the three months ended June 30, 2021
related to accounting and tax work, adding additional engineering and accounting contractors and legal fees related
to the arbitration of an employment claim. <i>See Note 9 Commitments, Contingencies and Related Party Transactions-Arbitration of Employment
Claim</i> in the Notes to the condensed consolidated financial statements included in Part I, Item 1 of this report. Compensation
and benefits, including director fees increased $39 thousand from the comparable period in 2020 due to the hiring in April 2021 of a

contract represented approximately 28% of our oil production for the three months ended June 30, 2021. The loss is related to a
change in the fair value of the fixed-price swap contract due to the increase in the price of crude oil during the period. <i>See

for the three months ended June 30, 2021 was attributable to an increase in the value of our common stock during the period, which was
partially offset by a decrease in the warrant liability due to the exercise of warrants to purchase 50,000 shares of common stock (leaving
warrants to purchase 50,000 shares of common stock outstanding), which occurred in the third fiscal quarter of 2020.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">The increase in our oil and gas revenue of $1,755
thousand for the six months ended June 30, 2021 as compared to the six months ended June 30, 2020 was due primarily to an increase in
oil production of 44% and an increase in the realized price received for our oil production of 74%. The increase in oil prices is primarily
due to stronger demand for crude oil on a global basis as the world recovered from government mandated lockdowns which began in
mid-March 2020, to reduce the spread of COVID-19. The increase in oil production volumes is primarily the result of the acquisitions
of properties we completed during 2020, and our efforts in the first six months of 2021 to return idle wells to production. During the
six months ended June 30, 2021, we produced 16,875 Bbls of oil from properties acquired in the second half of 2020.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For the six months ended June 30, 2021, we produced
57,978 BOE, or an average of 320 BOE per day, as compared to 40,920 BOE or 225 BOE per day during the comparable period in 2020. This
increase was mainly attributable to the acquisition of properties in the last half of 2020 and the return to production of idle wells
during the six months ended June 30, 2021. In addition, during the six months ended June 30, 2020, certain North Dakota operators temporarily
 shut-in production in response to low commodity prices.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">General and administrative expenses increased by
$608 thousand during six-month period ended June 30, 2021 as compared to the six-month period ended June 30, 2020 due to an increase
in professional fees of $378 thousand. The increase was primarily attributable to an increase in legal fees. On March 4, 2021,
we issued 90,846 shares of unregistered common stock valued at $406 thousand to APEG in reimbursement of legal costs they incurred
in the Texas and Colorado Litigation, which was dismissed in 2020. <i>See Note 9-Commitments, Contingencies and Related Party Transactions-APEG
II Litigation </i>in the Notes to the condensed consolidated financial statements included in Part I, Item 1 of this report. Compensation
and benefits increased $230 thousand due to the hiring in April 2021 of a new Vice President of Operations and an increase in the amortization
of stock-based compensation due to awards granted to our officers and directors in January and February 2021.</p>

a $1,054 thousand loss to adjust the carrying amount of the land and building to its estimated fair value of $975 thousand. See <i>Note

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify">For the six months ended June 30, 2021, we
recognized a loss on our fixed-price swap commodity derivative contract of $210 thousand. In March 2021, we entered into the swap
contract to fix the price of 100 barrels of crude oil at $61.90 per barrel through December 31, 2021. The fixed-price swap
contract represented approximately 32% of our oil production for the six months ended June 30, 2021. The loss is related to a
change in the fair value of the fixed-price swap contract due to the increase in the price of crude oil during the period. <i>See

an unrealized gain on marketable equity securities of $73 thousand as compared to an unrealized loss of $121 thousand for the comparable
period of 2020. The unrealized gain represents the increase in value of our investment in Anfield Energy Inc. See <i>Note 15. Fair

a warrant revaluation loss of $24 thousand as compared to a loss of $120 thousand during the six months ended June 30, 2020. The loss
during the three months ended June 30, 2021 was attributable to an increase in the warrant liability, primarily as a result of the increase
in the value of our common stock.</p>

Riverton, Wyoming with a two-story, 30,400 square foot office building and an additional 13-acre parcel of land adjacent to the building.
The building served as our corporate headquarters until 2015 and is currently being leased to government agencies and other non-affiliated
companies. During 2020, we made the decision to sell the land and building and began a process to determine the price at which we would
list the property for sale. The process included obtaining an appraisal, analyzing operating statements for the building, reviewing capitalization
rates and consulting a large national commercial real estate company. We determined the realizable value of the real estate assets was
in the range of $950 thousand to $1.2 million. A special committee of the board of directors was formed to evaluate the sales process
and during 2020, we entered into an agreement with a large national commercial broker and a local broker in Riverton, Wyoming to sell
our real estate assets.</p>

issuing additional shares of our common stock for cash or as consideration for acquisitions, and other alternatives, as we determine
how to best fund our capital programs and meet our financial obligations.</p>

that information required to be disclosed is accumulated and communicated to management, including our Chief Executive Officer and Chief

of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e)

disclosure controls were not effective as of June 30, 2021 to ensure that information required to be disclosed by us in reports that we
file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and

deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility

2021, in connection with our assessment of the effectiveness of our internal control over financial reporting at the end of our last fiscal

principles (&#x201c;GAAP&#x201d;) and have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange
Commission (the &#x201c;SEC&#x201d;) regarding interim financial reporting. Accordingly, certain information and footnote disclosures required
by GAAP for complete financial statements have been condensed or omitted in accordance with such rules and regulations. In the opinion
of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the consolidated
financial statements have been included.&lt;/span&gt;&lt;/p&gt;

further information, refer to the consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K
for the year ended December 31, 2020, as filed with the SEC on March 26, 2021. Our financial condition as of June 30, 2021, and operating
results for the three and six months ended June 30, 2021, are not necessarily indicative of the financial condition and results of operations
that may be expected for any future interim period or for the year ending December 31, 2021.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
preparation of financial statements in conformity with generally accepted accounting principles in the United States (&#x201c;GAAP&#x201d;)
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, 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. Significant estimates include oil and natural gas reserves that are used in the calculation of depreciation, depletion, amortization
and impairment of the carrying value of evaluated oil and natural gas properties; realizability of unevaluated properties; production
and commodity price estimates used to record accrued oil and natural gas sales receivables; futures prices of commodities used in the
valuation of commodity derivative contracts; valuation of warrant instruments; valuation of real estate assets held for sale; and the
cost of future asset retirement obligations. The Company evaluates its estimates on an on-going basis and bases its estimates on historical
experience and on various other assumptions the Company believes to be reasonable. Due to inherent uncertainties, including the future
prices of oil and natural gas, these estimates could change in the near term and such changes could be material.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;The Company does not designate commodity derivative
contracts as cash flow hedges, and therefore the contracts do not qualify for hedge accounting. Changes in fair value of derivative
contracts are recorded in the condensed consolidated statement of operations. The fair value of derivative contracts are
recorded as either an asset or a liability on the condensed consolidated balance sheet.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
preparation of financial statements in conformity with generally accepted accounting principles in the United States (&#x201c;GAAP&#x201d;)
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, 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. Significant estimates include oil and natural gas reserves that are used in the calculation of depreciation, depletion, amortization
and impairment of the carrying value of evaluated oil and natural gas properties; realizability of unevaluated properties; production
and commodity price estimates used to record accrued oil and natural gas sales receivables; futures prices of commodities used in the
valuation of commodity derivative contracts; valuation of warrant instruments; valuation of real estate assets held for sale; and the
cost of future asset retirement obligations. The Company evaluates its estimates on an on-going basis and bases its estimates on historical
experience and on various other assumptions the Company believes to be reasonable. Due to inherent uncertainties, including the future
prices of oil and natural gas, these estimates could change in the near term and such changes could be material.&lt;/span&gt;&lt;/p&gt;

leased to government agencies and other non-affiliated companies. During the year ended December 31, 2020, the Company made the decision
to sell the land and building and began a process to determine the price at which it would list the property for sale. The process included
obtaining an appraisal, analyzing operating statements for the building, reviewing capitalization rates and consulting a large national
commercial real estate company. The Company determined that the realizable value of the building and the building land was in the range
of $&lt;span id="xdx_908_eus-gaap--ReorganizationValue_c20210630__srt--RangeAxis__srt--MinimumMember_pn3n3" title="Realizable value"&gt;700&lt;/span&gt; thousand to $&lt;span id="xdx_90A_eus-gaap--ReorganizationValue_c20210630__srt--RangeAxis__srt--MaximumMember_pn3n3" title="Realizable value"&gt;900&lt;/span&gt; thousand and the realizable value of the additional land was in the range of $&lt;span id="xdx_90B_ecustom--RealizableValueForAdditionalLand_c20210630__srt--RangeAxis__srt--MinimumMember_pn3n3" title="Realizable value for additional land"&gt;250&lt;/span&gt; thousand to $&lt;span id="xdx_90D_ecustom--RealizableValueForAdditionalLand_c20210630__srt--RangeAxis__srt--MaximumMember_pn3n3" title="Realizable value for additional land"&gt;300&lt;/span&gt; thousand.
A special committee of the board of directors was formed to evaluate the sales process. During 2020, the Company entered into an agreement
with a large national commercial broker and a local broker in Riverton, Wyoming to sell the building and the land. During the year ended
December 31, 2020, the Company recognized a loss on the land and building of $&lt;span id="xdx_902_eus-gaap--GainLossOnSaleOfPropertyPlantEquipment_pn3n3_c20200101__20201231_zLjBNBbAHQ84" title="Loss on land and building"&gt;1,054&lt;/span&gt; thousand. The Company has accepted an offer to purchase
the building and the associated land and expects the sale to be completed in 2021. The following are the estimated fair values and the
estimated net proceeds relating to the real estate assets held for sale at June 30, 2021 and December 31, 2020:&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company&#x2019;s revenues are primarily derived from its non-operated interest in the sales of oil and natural gas production. The sales
of oil and natural gas are made under contracts that operators of the wells have negotiated with third-party customers. The Company receives
payment from the sale of oil and natural gas production between one to three months after delivery. At the end of each period when the
performance obligation is satisfied, the variable consideration can be reasonably estimated and amounts due from customers are accrued
in oil and natural gas sales receivable in the consolidated balance sheets. Variances between the Company&#x2019;s estimated revenue and
actual payments are recorded in the month the payment is received. Accordingly,
the variable consideration is not constrained. As a non-operator of its oil and natural gas properties, the Company records its share
of the revenues and expenses based upon the information provided by the operators within the revenue statements.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company&#x2019;s oil and natural gas production is typically sold at delivery points to various purchasers under contract terms that are
common in the oil and natural gas industry. Regardless of the contract type, the terms of these contracts compensate the well operators
for the value of the oil and natural gas at specified prices, and then the well operators remit payment to the Company for its share
in the value of the oil and natural gas sold.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;During
2020, the Company acquired operated oil and gas producing properties (see Note 2- &lt;i&gt;Acquisitions&lt;/i&gt;, above). The Company sells its
oil production at the delivery point specified in the contract and collects an agreed-upon index price, net of pricing differentials.
The purchaser takes custody, title and risk of loss of the oil at the delivery point; therefore, control passes at the delivery point.
The Company recognizes revenue at the net price received when control transfers to the purchaser. Natural gas and natural gas liquid
(&#x201c;NGL&#x201d;) are sold at the lease location, which is generally when control of the natural gas and NGL transfers to the purchaser,
and revenue is recognized as the amount received from the purchaser.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company does not disclose the values of unsatisfied performance obligations under its contracts with customers as it applies the practical
exemption in accordance with Accounting Standards Codification (ASC) 606. The exemption applies to variable consideration that is recognized
as control of the product is transferred to the customer. Since each unit of product represents a separate performance obligation, future
volumes are wholly unsatisfied, and disclosure of the transaction price allocated to the remaining performance obligations is not required.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company reports revenue as the gross amount received from the well operators before taking into account production taxes and transportation
costs. Production taxes are reported separately, and transportation costs are included in lease operating expense in the accompanying
unaudited condensed consolidated statements of operations. The revenue and costs in the consolidated statements of operations were reported
gross for the three and six months ended June 30, 2021 and 2020, as the gross amounts were known.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company&#x2019;s operated revenues are growing. Operated revenues for the three months ended June 30, 2021, and 2020 were &lt;span id="xdx_904_ecustom--OperatingRevenuePercentage_pid_dp_uPercent_c20210401__20210630_znZBlG5Ohya5" title="Operating revenue percentage"&gt;32&lt;/span&gt;% and &lt;span id="xdx_90E_ecustom--OperatingRevenuePercentage_pid_dp_uPercent_c20200401__20200630_zuajfH0gjvG2"&gt;14&lt;/span&gt;%
of total revenues, respectively. The Company&#x2019;s operated revenues for the six months ended June 30, 2021, and 2020 were &lt;span id="xdx_90F_ecustom--OperatingRevenuePercentage_pid_dp_uPercent_c20210101__20210630_z6g8rtpXhF4j"&gt;32&lt;/span&gt;% and

by state. The Company&#x2019;s revenues in North Dakota, Texas, New Mexico and other states for the three and six months ended June

Company recognizes lease expense on a straight-line basis excluding short-term and variable lease payments, which are recognized as incurred.
Short-term lease costs represent payments for our Houston, Texas office lease, prior to February 2021, when the Company entered into
a new &lt;span title="Lease term"&gt;&lt;span id="xdx_904_eus-gaap--LesseeOperatingLeaseTermOfContract_iI_dtM_c20210630_zna9UNy5O2wi" title="Lease term"&gt;25&lt;/span&gt;-month&lt;/span&gt; lease for its Houston office. Beginning in March 2020, the Company subleased its Denver, Colorado office and recognizes
sublease income as a reduction of rent expense. Following are the amounts recognized as components of rental expense for the three and
six months ended June 30, 2021 and 2020:&lt;/span&gt;&lt;/p&gt;

Company&#x2019;s results of operations and cash flows are affected by changes in market prices for crude oil and natural gas. To manage
a portion of its exposure to price volatility from producing crude oil, the Company entered into a fixed-price swap commodity derivative
contract to protect against price declines in future periods on 100 barrels of crude oil per day from March 1 to December 31, 2021, at
$61.90&lt;/span&gt;, based on the calendar month average of West Texas Intermediate Crude Oil (&#x201c;WTI&#x201d;). There are no collateral requirements
for the fixed-price swap derivative contract. The Company does not enter into derivative contracts for speculative purposes. The Company
has not elected to designate the fixed-price swap as a cash flow hedge; therefore, the instrument does not qualify for hedge accounting.
Accordingly, changes in the fair value of the fixed-price swap contract are recoded in the unaudited condensed consolidated statements
of operations and are included in cash flows from operating activities in the condensed consolidated statement of cash flows.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;In
July 2020, the Company received a request for arbitration from its former Chief Executive Officer, David Veltri claiming that the Company
breached his employment agreement. The Company intends to vigorously contest this matter and believes these claims are without merit.
The employment agreement requires that any disputes be submitted to binding arbitration. The Company has insurance for these types of
claims and has reported the request for arbitration to its insurance carrier. Through June 30, 2021, the Company has incurred defense
costs in this matter of $&lt;span id="xdx_909_ecustom--IncurredDefenceCosts_iI_pn3n3_c20210630_zZMJUc8WpUbf" title="Defense costs"&gt;117&lt;/span&gt; thousand and has accrued $&lt;span id="xdx_906_eus-gaap--AccruedLiabilitiesCurrentAndNoncurrent_c20210630_pn3n3" title="Accrued liability"&gt;10&lt;/span&gt; thousand for future defense costs, representing the Company&#x2019;s responsibility

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;From
February 2019 until August 2020, the Company was involved in litigation with its former Chief Executive Officer, David Veltri and at
the time its largest shareholder, APEG II and APEG II&#x2019;s general partner, APEG Energy II, GP (together with APEG II, &#x201c;APEG&#x201d;).
In addition, Patrick E. Duke, a former director of the Company, had shared voting and shared investment power over APEG. The litigation
arose as a result of a vote at the February 25, 2019 board of directors meeting to terminate Mr. Veltri for using Company funds outside
of his authority and for other reasons (the &#x201c;Texas Litigation&#x201d;). In a separate lawsuit, APEG initiated a shareholder derivative
action in Colorado against Mr. Veltri due to his refusal to recognize the Board&#x2019;s decision to terminate him (the &#x201c;Colorado
Litigation&#x201d;). The Company was named as a nominal defendant in the Colorado Litigation. The Colorado litigation was dismissed in
May 2020 and the Texas Litigation was dismissed in August 2020. On March 4, 2021, the Company issued &lt;span id="xdx_906_eus-gaap--StockIssuedDuringPeriodSharesIssuedForServices_c20210303__20210304__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pdd" title="Stock Issued During Period, Shares, Issued for Services"&gt;90,846&lt;/span&gt; shares of unregistered common

and Texas Litigation.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company has asset retirement obligations (&#x201c;AROs&#x201d;) associated with the future plugging and abandonment of proved properties.
Initially, the fair value of a liability for an ARO is recorded in the period in which the ARO is incurred with a corresponding increase
in the carrying amount of the related asset. The liability is accreted to its present value each period and the capitalized cost is depleted
over the life of the related asset. If the liability is settled for an amount other than the recorded amount, an adjustment to the full-cost
pool is recognized. The Company had no assets that are restricted for the purpose of settling AROs.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;In
the fair value calculation for the ARO there are numerous assumptions and judgments, including the ultimate retirement cost, inflation
factors, credit-adjusted risk-free discount rates, timing of retirement and changes in legal, regulatory, environmental, and political
environments. To the extent future revisions to assumptions and judgments impact the present value of the existing ARO, a corresponding
adjustment is made to the oil and natural gas property balance.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

estimate income taxes on a current year-to-date basis is &lt;span id="xdx_904_eus-gaap--EffectiveIncomeTaxRateContinuingOperations_pid_dp_uPercent_c20200101__20200630_zUDYiqc8FsQa" title="Effective income tax rate"&gt;&lt;span id="xdx_908_eus-gaap--EffectiveIncomeTaxRateContinuingOperations_pid_dp_uPercent_c20210101__20210630_zJRMTK8J51Cf"&gt;0&lt;/span&gt;&lt;/span&gt;% for the six months ended June 30, 2021 and 2020.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;




&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

tax assets (&#x201c;DTAs&#x201d;) are recognized for the expected future tax consequences of temporary differences between the financial
reporting and tax basis of assets and liabilities and for operating losses and tax credit carry-forwards. We review our DTAs and valuation
allowance on a quarterly basis. As part of our review, we consider positive and negative evidence, including cumulative results in recent
years. Consistent with the position at December 31, 2020, the Company maintains a full valuation allowance recorded against all DTAs.
The Company, therefore, had no recorded DTAs as of June 30, 2021. We anticipate that we will continue to record a valuation allowance
against our DTAs in all jurisdictions until such time as we are able to determine that it is &#x201c;more-likely-than-not&#x201d; that
those DTAs will be realized.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;At
December 31, 2020, the Company had approximately $&lt;span id="xdx_902_eus-gaap--OperatingLossCarryforwards_iI_pn5n6_c20201231_zkPwo7rw93sh" title="Net operating loss carryovers"&gt;8.9&lt;/span&gt; million in net operating loss carryovers (after limitations). During the six months
ended June 30, 2021 and year ended December 31, 2020, the Company issued approximately &lt;span id="xdx_90F_eus-gaap--StockIssuedDuringPeriodSharesNewIssues_pn5n6_c20210101__20210630_zLRUYq3U8Tj9" title="Number of share issued"&gt;1.3&lt;/span&gt; million and &lt;span id="xdx_909_eus-gaap--StockIssuedDuringPeriodSharesNewIssues_pdn6_c20200101__20201231_zVF7MBPofNs5" title="Number of share issued"&gt;2.0&lt;/span&gt; million additional shares
of common stock, respectively in various transactions. The Company is currently evaluating whether these issuances represented an ownership
change that would have triggered a loss limitation under Internal Revenue Code (&#x201c;I.R.C.&#x201d;) Section 382. However, since the
Company maintains a valuation allowance against these tax assets there is no impact to the condensed consolidated statement of operations
for the three and six months ended June 30, 2021.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company recognizes, measures, and discloses uncertain tax positions whereby tax positions must meet a &#x201c;more-likely-than-not&#x201d;
threshold to be recognized. During the three and six months ended June 30, 2021 and 2020, &lt;span id="xdx_907_eus-gaap--UnrecognizedTaxBenefits_iI_pp0p0_do_c20210630_ziSaPvtIFqWe" title="Uncertain tax positions"&gt;&lt;span id="xdx_903_eus-gaap--UnrecognizedTaxBenefits_iI_pp0p0_do_c20200630_zmkmjtDKouf6" title="Uncertain tax positions"&gt;no&lt;/span&gt;&lt;/span&gt; adjustments were recognized for uncertain
tax positions.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;Basic
net loss per common share is calculated by dividing net loss attributable to common shareholders by the weighted-average number of common
shares outstanding for the respective period. Diluted net loss per common share is calculated by dividing adjusted net loss by the diluted
weighted average number of common shares outstanding, which includes the effect of potentially dilutive securities. Potentially dilutive
securities for this calculation consist of stock options and warrants, which are measured using the treasury stock method, the conversion
feature of the Series A Preferred Stock prior to redemption, and unvested shares of restricted common stock. When the Company recognizes
a net loss, as was the case for the three and six months ended June 30, 2021 and 2020, all potentially dilutive shares are anti-dilutive
and are consequently excluded from the calculation of dilutive net loss per common share.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;span id="xdx_82E_zVra2n4Ur0yl"&gt;FAIR VALUE MEASUREMENTS&lt;/span&gt;&lt;/b&gt;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company&#x2019;s fair value measurements are estimated pursuant to a fair value hierarchy that requires us to maximize the use of observable
inputs and minimize the use of unobservable inputs when measuring fair value. The valuation hierarchy is based upon the transparency
of inputs to the valuation of an asset or liability as of the measurement date, giving highest priority to quoted prices in active markets
(Level 1) and the lowest priority to unobservable data (Level 3). In some cases, the inputs used to measure fair value might fall in
different levels of the fair value hierarchy. The lowest level input that is significant to a fair value measurement in its entirety
determines the applicable level in the fair value hierarchy. Assessing the significance of a particular input to the fair value measurement
in its entirety requires judgment, considering factors specific to the asset or liability, and may affect the valuation of the assets
and liabilities and their placement within the hierarchy level. The three levels of inputs that may be used to measure fair value are
defined as:&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;Level
1 - Quoted prices for identical assets and liabilities traded in active exchange markets.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;Level
2 - Observable inputs other than Level 1 that are directly or indirectly observable for the asset or liability, including quoted prices
for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities inactive markets, or
other observable inputs that can be corroborated by observable market data.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;Level
3 - Unobservable inputs supported by little or no market activity for financial instruments whose value is determined using pricing models,
discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires
significant management judgment or estimation.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
warrants contain a dilutive issuance and other provisions that cause the warrants to be accounted for as a liability. Such warrant instruments
are initially recorded and valued as a Level 3 liability and are accounted for at fair value with changes in fair value reported in earnings.
There were no changes in the methodology to value the warrants. The Company worked with a third-party valuation expert to estimate the
value of the warrants at December 31, 2020 using a Black Scholes model, with the following observable and unobservable inputs:&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;During
the six months ended June 30, 2021, the Company entered into a fixed-price swap derivative contract. The Company measures the fair value
of derivative contracts using an income valuation technique based on the contract price of the underlying positions, crude oil forward
curves, discount rates, and counterparty non-performance risk from a marketplace participant&#x2019;s perspective. The fixed-price swap
derivative contract is included in Level 2.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company measures the fair value of asset retirement obligations as of the date a well is acquired or the date a well begins drilling
using a discounted cash flow method based on unobservable inputs in the market and therefore are designated as Level 3 within the valuation
hierarchy.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company evaluates the fair value on a non-recurring basis of properties acquired in business combinations. The fair value of the oil
and gas properties is determined based upon estimated future discounted cash flow, a Level 3 input, using estimated production which
we reasonably expect, and estimated prices adjusted for differentials. Unobservable inputs include estimated future oil and natural gas
production, prices, operating and development costs, and a discount rate of &lt;span id="xdx_90D_eus-gaap--WarrantsAndRightsOutstandingMeasurementInput_iI_pid_uPercent_c20201231__us-gaap--MeasurementInputTypeAxis__us-gaap--MeasurementInputDiscountRateMember_zgdkqN0fyCW" title="Fair value meaeurement input"&gt;10&lt;/span&gt;%, all Level 3 inputs within the fair value hierarchy.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company evaluates the fair value on a non-recurring basis of its Riverton, Wyoming real estate assets when circumstances indicate that
the value has been impaired. The change in the economic environment due to the COVID-19 pandemic and the property&#x2019;s remote location
has caused a lack of relevant comparable sales to use as a basis for estimating fair value. At June 30, 2021, the Company estimated the
fair value of the real estate based upon offers it had received for the real estate, the expected annual net operating income of the
building, estimated capitalization rates for properties in rural areas and values for vacant land based on comparable sales, all Level
3 inputs within the fair value hierarchy.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
carrying value of financial instruments included in current assets and current liabilities approximate fair value due to the short-term
nature of those instruments.&lt;/span&gt;&lt;/p&gt;

preparation of financial statements in conformity with generally accepted accounting principles in the United States (&#8220;GAAP&#8221;)
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, 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. Significant estimates include oil and natural gas reserves that are used in the calculation of depreciation, depletion, amortization
and impairment of the carrying value of evaluated oil and natural gas properties; realizability of unevaluated properties; production
and commodity price estimates used to record accrued oil and natural gas sales receivables; futures prices of commodities used in the
valuation of commodity derivative contracts; valuation of warrant instruments; valuation of real estate assets held for sale; and the
cost of future asset retirement obligations. The Company evaluates its estimates on an on-going basis and bases its estimates on historical
experience and on various other assumptions the Company believes to be reasonable. Due to inherent uncertainties, including the future
prices of oil and natural gas, these estimates could change in the near term and such changes could be material.</span></p>

of land adjacent to the building. The building served as the Company&#8217;s corporate headquarters until 2015 and is currently being
leased to government agencies and other non-affiliated companies. During the year ended December 31, 2020, the Company made the decision
to sell the land and building and began a process to determine the price at which it would list the property for sale. The process included
obtaining an appraisal, analyzing operating statements for the building, reviewing capitalization rates and consulting a large national
commercial real estate company. The Company determined that the realizable value of the building and the building land was in the range
of $<span id="xdx_908_eus-gaap--ReorganizationValue_c20210630__srt--RangeAxis__srt--MinimumMember_pn3n3" title="Realizable value">700</span> thousand to $<span id="xdx_90A_eus-gaap--ReorganizationValue_c20210630__srt--RangeAxis__srt--MaximumMember_pn3n3" title="Realizable value">900</span> thousand and the realizable value of the additional land was in the range of $<span id="xdx_90B_ecustom--RealizableValueForAdditionalLand_c20210630__srt--RangeAxis__srt--MinimumMember_pn3n3" title="Realizable value for additional land">250</span> thousand to $<span id="xdx_90D_ecustom--RealizableValueForAdditionalLand_c20210630__srt--RangeAxis__srt--MaximumMember_pn3n3" title="Realizable value for additional land">300</span> thousand.
A special committee of the board of directors was formed to evaluate the sales process. During 2020, the Company entered into an agreement
with a large national commercial broker and a local broker in Riverton, Wyoming to sell the building and the land. During the year ended
December 31, 2020, the Company recognized a loss on the land and building of $<span id="xdx_902_eus-gaap--GainLossOnSaleOfPropertyPlantEquipment_pn3n3_c20200101__20201231_zLjBNBbAHQ84" title="Loss on land and building">1,054</span> thousand. The Company has accepted an offer to purchase
the building and the associated land and expects the sale to be completed in 2021. The following are the estimated fair values and the
estimated net proceeds relating to the real estate assets held for sale at June 30, 2021 and December 31, 2020:</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">&#160;</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">The
Company&#8217;s revenues are primarily derived from its non-operated interest in the sales of oil and natural gas production. The sales
of oil and natural gas are made under contracts that operators of the wells have negotiated with third-party customers. The Company receives
payment from the sale of oil and natural gas production between one to three months after delivery. At the end of each period when the
performance obligation is satisfied, the variable consideration can be reasonably estimated and amounts due from customers are accrued
in oil and natural gas sales receivable in the consolidated balance sheets. Variances between the Company&#8217;s estimated revenue and
actual payments are recorded in the month the payment is received. Accordingly,
the variable consideration is not constrained. As a non-operator of its oil and natural gas properties, the Company records its share
of the revenues and expenses based upon the information provided by the operators within the revenue statements.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">&#160;</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">The
Company&#8217;s oil and natural gas production is typically sold at delivery points to various purchasers under contract terms that are
common in the oil and natural gas industry. Regardless of the contract type, the terms of these contracts compensate the well operators
for the value of the oil and natural gas at specified prices, and then the well operators remit payment to the Company for its share
in the value of the oil and natural gas sold.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">&#160;</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">During
2020, the Company acquired operated oil and gas producing properties (see Note 2- <i>Acquisitions</i>, above). The Company sells its
oil production at the delivery point specified in the contract and collects an agreed-upon index price, net of pricing differentials.
The purchaser takes custody, title and risk of loss of the oil at the delivery point; therefore, control passes at the delivery point.
The Company recognizes revenue at the net price received when control transfers to the purchaser. Natural gas and natural gas liquid
(&#8220;NGL&#8221;) are sold at the lease location, which is generally when control of the natural gas and NGL transfers to the purchaser,
and revenue is recognized as the amount received from the purchaser.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">The
Company does not disclose the values of unsatisfied performance obligations under its contracts with customers as it applies the practical
exemption in accordance with Accounting Standards Codification (ASC) 606. The exemption applies to variable consideration that is recognized
as control of the product is transferred to the customer. Since each unit of product represents a separate performance obligation, future
volumes are wholly unsatisfied, and disclosure of the transaction price allocated to the remaining performance obligations is not required.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">&#160;</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">The
Company reports revenue as the gross amount received from the well operators before taking into account production taxes and transportation
costs. Production taxes are reported separately, and transportation costs are included in lease operating expense in the accompanying
unaudited condensed consolidated statements of operations. The revenue and costs in the consolidated statements of operations were reported
gross for the three and six months ended June 30, 2021 and 2020, as the gross amounts were known.</span></p>

Company&#8217;s results of operations and cash flows are affected by changes in market prices for crude oil and natural gas. To manage
a portion of its exposure to price volatility from producing crude oil, the Company entered into a fixed-price swap commodity derivative
contract to protect against price declines in future periods on 100 barrels of crude oil per day from March 1 to December 31, 2021, at
$61.90</span>, based on the calendar month average of West Texas Intermediate Crude Oil (&#8220;WTI&#8221;). There are no collateral requirements
for the fixed-price swap derivative contract. The Company does not enter into derivative contracts for speculative purposes. The Company
has not elected to designate the fixed-price swap as a cash flow hedge; therefore, the instrument does not qualify for hedge accounting.
Accordingly, changes in the fair value of the fixed-price swap contract are recoded in the unaudited condensed consolidated statements
of operations and are included in cash flows from operating activities in the condensed consolidated statement of cash flows.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">In
July 2020, the Company received a request for arbitration from its former Chief Executive Officer, David Veltri claiming that the Company
breached his employment agreement. The Company intends to vigorously contest this matter and believes these claims are without merit.
The employment agreement requires that any disputes be submitted to binding arbitration. The Company has insurance for these types of
claims and has reported the request for arbitration to its insurance carrier. Through June 30, 2021, the Company has incurred defense
costs in this matter of $<span id="xdx_909_ecustom--IncurredDefenceCosts_iI_pn3n3_c20210630_zZMJUc8WpUbf" title="Defense costs">117</span> thousand and has accrued $<span id="xdx_906_eus-gaap--AccruedLiabilitiesCurrentAndNoncurrent_c20210630_pn3n3" title="Accrued liability">10</span> thousand for future defense costs, representing the Company&#8217;s responsibility

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify; background-color: white"><span style="font: 10pt Times New Roman, Times, Serif">From
February 2019 until August 2020, the Company was involved in litigation with its former Chief Executive Officer, David Veltri and at
the time its largest shareholder, APEG II and APEG II&#8217;s general partner, APEG Energy II, GP (together with APEG II, &#8220;APEG&#8221;).
In addition, Patrick E. Duke, a former director of the Company, had shared voting and shared investment power over APEG. The litigation
arose as a result of a vote at the February 25, 2019 board of directors meeting to terminate Mr. Veltri for using Company funds outside
of his authority and for other reasons (the &#8220;Texas Litigation&#8221;). In a separate lawsuit, APEG initiated a shareholder derivative
action in Colorado against Mr. Veltri due to his refusal to recognize the Board&#8217;s decision to terminate him (the &#8220;Colorado
Litigation&#8221;). The Company was named as a nominal defendant in the Colorado Litigation. The Colorado litigation was dismissed in
May 2020 and the Texas Litigation was dismissed in August 2020. On March 4, 2021, the Company issued <span id="xdx_906_eus-gaap--StockIssuedDuringPeriodSharesIssuedForServices_c20210303__20210304__srt--TitleOfIndividualAxis__srt--ChiefExecutiveOfficerMember_pdd" title="Stock Issued During Period, Shares, Issued for Services">90,846</span> shares of unregistered common

Company has asset retirement obligations (&#8220;AROs&#8221;) associated with the future plugging and abandonment of proved properties.
Initially, the fair value of a liability for an ARO is recorded in the period in which the ARO is incurred with a corresponding increase
in the carrying amount of the related asset. The liability is accreted to its present value each period and the capitalized cost is depleted
over the life of the related asset. If the liability is settled for an amount other than the recorded amount, an adjustment to the full-cost
pool is recognized. The Company had no assets that are restricted for the purpose of settling AROs.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">&#160;</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">In
the fair value calculation for the ARO there are numerous assumptions and judgments, including the ultimate retirement cost, inflation
factors, credit-adjusted risk-free discount rates, timing of retirement and changes in legal, regulatory, environmental, and political
environments. To the extent future revisions to assumptions and judgments impact the present value of the existing ARO, a corresponding
adjustment is made to the oil and natural gas property balance.</span></p>

tax assets (&#8220;DTAs&#8221;) are recognized for the expected future tax consequences of temporary differences between the financial
reporting and tax basis of assets and liabilities and for operating losses and tax credit carry-forwards. We review our DTAs and valuation
allowance on a quarterly basis. As part of our review, we consider positive and negative evidence, including cumulative results in recent
years. Consistent with the position at December 31, 2020, the Company maintains a full valuation allowance recorded against all DTAs.
The Company, therefore, had no recorded DTAs as of June 30, 2021. We anticipate that we will continue to record a valuation allowance

those DTAs will be realized.</span></p>

a net loss, as was the case for the three and six months ended June 30, 2021 and 2020, all potentially dilutive shares are anti-dilutive
and are consequently excluded from the calculation of dilutive net loss per common share.</span></p>

Company&#8217;s fair value measurements are estimated pursuant to a fair value hierarchy that requires us to maximize the use of observable
inputs and minimize the use of unobservable inputs when measuring fair value. The valuation hierarchy is based upon the transparency
of inputs to the valuation of an asset or liability as of the measurement date, giving highest priority to quoted prices in active markets
(Level 1) and the lowest priority to unobservable data (Level 3). In some cases, the inputs used to measure fair value might fall in
different levels of the fair value hierarchy. The lowest level input that is significant to a fair value measurement in its entirety
determines the applicable level in the fair value hierarchy. Assessing the significance of a particular input to the fair value measurement
in its entirety requires judgment, considering factors specific to the asset or liability, and may affect the valuation of the assets
and liabilities and their placement within the hierarchy level. The three levels of inputs that may be used to measure fair value are
defined as:</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">Level
2 - Observable inputs other than Level 1 that are directly or indirectly observable for the asset or liability, including quoted prices
for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities inactive markets, or
other observable inputs that can be corroborated by observable market data.</span></p>

3 - Unobservable inputs supported by little or no market activity for financial instruments whose value is determined using pricing models,
discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires
significant management judgment or estimation.</span></p>

warrants contain a dilutive issuance and other provisions that cause the warrants to be accounted for as a liability. Such warrant instruments
are initially recorded and valued as a Level 3 liability and are accounted for at fair value with changes in fair value reported in earnings.
There were no changes in the methodology to value the warrants. The Company worked with a third-party valuation expert to estimate the
value of the warrants at December 31, 2020 using a Black Scholes model, with the following observable and unobservable inputs:</span></p>

assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting
period. Significant estimates include oil and natural gas reserves that are used in the calculation of depreciation, depletion, amortization
and impairment of the carrying value of evaluated oil and natural gas properties; realizability of unevaluated properties; production
and commodity price estimates used to record accrued oil and natural gas sales receivables; futures prices of commodities used in the
valuation of commodity derivative contracts; valuation of warrant instruments; valuation of real estate assets held for sale; and the
cost of future asset retirement obligations. The Company evaluates its estimates on an on-going basis and bases its estimates on historical
experience and on various other assumptions the Company believes to be reasonable. Due to inherent uncertainties, including the future
prices of oil and natural gas, these estimates could change in the near term and such changes could be material.</span></p>
