Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration that we expect to receive for those goods or services. To recognize revenue, we (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, we satisfy the performance obligation(s).

Our primary focus is on the rental of natural gas compressors. Our rental contracts typically provide for initial terms of six to 24 months, with our larger horsepower units having contract terms of up to 60 months. After the initial term of our rental contracts, many of our customers have continued to rent our compressors on a month-to-month basis. Rental amounts are billed monthly in advance and include maintenance of our rented compressors. As of March 31, 2022, we had 1,276 natural gas compressors totaling 306,834 horsepower rented to 79 customers compared to 1,265 natural gas compressors totaling 287,914 horsepower rented to 80 customers at March 31, 2021. </span></div><div><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We also fabricate natural gas compressors for sale to our customers, designing compressors to meet unique specifications dictated by well pressures, production characteristics, and particular applications for which compression is sought. Fabrication of compressors involves our purchase of engines, compressors, coolers, and other components, and our assembling of these components on skids for delivery to customer locations. The major components of our compressor packages are acquired through periodic purchase orders placed with third-party suppliers on an &#8220;as needed&#8221; basis, which presently require lead times between three to six months with delivery dates scheduled to coincide with our estimated production schedules. Although we do not have formal continuing supply contracts with any major supplier, we believe we have adequate alternative sources available. Recent inflationary pressures have created price increases in both major and minor components for our compressors as well as longer than normal lead times for such components. To date, we have been able to increase our rental rates and sales prices proportionally; however, if cost increases continue and we are no longer able to increase our rental rates and sales prices such an event could have a material adverse effect on the results of our operations and financial condition.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We also manufacture a proprietary line of compressor frames, cylinders and parts, known as our CiP (Cylinder-in-Plane) product line. We use finished CiP component products in the fabrication of compressor units for sale or rental by us or sell the finished component products to other compressor fabricators. We also design, fabricate, sell, install, and service flare stacks and related ignition and control devices for onshore and offshore incineration of gas compounds such as hydrogen sulfide, carbon dioxide, natural gas and liquefied petroleum gases. To provide customer support for our compressor and flare sales businesses, we stock varying levels of replacement parts at our Midland, Texas facility and at field service locations.

The most critical factor in assessing the outlook for the industry is the worldwide supply and demand for oil and natural gas and the corresponding changes in commodity prices. As demand and prices increase, oil and natural gas producers typically increase their capital expenditures for drilling, development and production activities, although recent equity capital constraints and demands from institutional investors to keep spending within operating cash flow have meaningfully restrained capital expenditure budgets of domestic exploration and production companies.  Generally, increased capital expenditures ultimately result in greater revenues and profits for service and equipment companies.</span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">In general, we expect our overall business activity and revenues to track the level of activity in the oil and natural gas industry, with changes in crude oil and condensate production and consumption levels and prices affecting our business more than changes in domestic natural gas production and consumption levels and prices. In recent years we have increased our rentals and sales in unconventional oil shale plays, which are more dependent on crude oil prices. With this shift towards oil production, the demand for overall compression services and products is driven by two general factors: an increased focus by producers on artificial lift applications, e.g., production enhancement with compression assisted gas lift; and declining reservoir pressure in maturing natural gas producing fields, especially unconventional production. These types of applications have historically been serviced by wellhead size compressors, and continue to be, but there has also been an economic move by our customers towards centralized drilling and production facilities, which have increased the market need for larger horsepower compressor packages. We recognized this need in recent years and have been shifting our cash and fabrication resources towards designing, fabricating and renting gas compressor packages that range from 400 horsepower up to 1,500 horsepower. While this is a response to market conditions and trends, it also provides us with the opportunity to compete as a full-line compression provider.</span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:700;line-height:120%">Industry Update</span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">We typically experience a decline in demand during periods of low crude oil and natural gas prices. During the first quarter of 2020, we saw a substantial decline in the prices for oil and natural gas. Commodity prices stabilized during 2021 with a sharp increase through the first three months of 2022. Historically, activity levels of exploration and production companies have been dependent on commodity prices. However, recent capital market focus on cash returns from exploration and production companies has restricted capital spending below levels that have historically been observed during higher commodity price environments. Generally, though, we feel that production activities (in which we are involved) will fare better than drilling activity. This is reflected in both the stability of our rental revenues, which is driven by production activities, and the volatility of our compressor sales, which tends to fluctuate with capital allocations. As such, we still expect compressor sales to be low for the remainder of 2022, as exploration and production companies have elected to rent compression units rather than allocating capital dollars to purchase new compression.   </span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div id="i0baaa49bcdbf4d41b0dcc6afaceab0d7_67"></div><div

The Company's total unit horsepower decreased to 421,422 horsepower at March 31, 2022 compared to 441,911 horsepower at March 31, 2021, due to the aforementioned unit retirements in the fourth quarter of 2021 partially offset by the addition to the Company's fleet of 27 high horsepower compressors with 10,900 horsepower over the past 12 months. As of March 31, 2022, we had 1,276 natural gas compressors with a total of 306,834 horsepower rented to 79 customers, compared to 1,265 natural gas compressors with a total of 287,914 horsepower rented to 80 customers as of March 31, 2021.  As a result, our total rented horsepower as of March 31, 2022 increased by 6.6% over the last twelve months.

Our total rented horsepower increased by 6.6% contrasted against a 0.9% increase in total rented units.

Under ASC 606, revenue is measured based on a consideration specified in a customer&#8217;s contract, excluding any sale incentives and taxes collected on behalf of third parties (i.e. sales and property taxes). Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration that we expect to receive for those goods or services. To recognize revenue, we (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, we satisfy the performance obligation(s). Shipping and handling costs incurred are accounted for as fulfillment costs and are included in cost of revenues in our condensed consolidated statements of operations. </span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Nature of Goods and Services</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The following is a description of principal activities from which the Company generates its revenue: </span></div><div style="text-align:justify;text-indent:36pt"><span><br/></span></div><div style="text-align:justify;text-indent:36pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Rental Revenue.  </span><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company generates revenue from renting compressors and flare systems to our customers.

<td class="text">Federal Income Tax ReceivableOn March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") was enacted in response to the economic impact caused by the COVID-19 pandemic. The CARES Act allowed NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid federal income taxes.  The Company generated significant NOLs during 2018 and 2019, and has filed amended returns to carryback these losses for five years. Accordingly, during 2020, the Company recorded a federal income tax receivable of $15.0&#160;million and an increase to its deferred income tax liability of $10.1&#160;million on its condensed consolidated balance sheet.  During the third quarter of 2020, the Company received refunds totaling $3.9&#160;million related to its 2018 NOLs, which reduced its federal income tax receivable to $11.5 million on its condensed consolidated balance sheet as of March 31, 2022.<span></span>

Committee issued a long-term incentive award of $1.0 million to an executive officer that vests in equal, annual tranches over 3 years beginning on the anniversary of the grant date. In addition, on March 18, 2021, we issued a $50,000 award to three of our independent members of our Board of Directors as partial payment for their services in 2021. On April 1, 2021, we issued a $50,000 award to a newly appointed independent member of our Board of Directors as partial payment for his services in 2021. These awards vest one year from the date of grant and are payable in cash upon vesting. There were no long-term incentive awards issued to executives of directors during the three months ended March 31, 2022. The Company accounts for these other long-term incentive awards as liabilities under accrued liabilities on our condensed consolidated balance sheet. The vesting of these awards awards is subject to acceleration upon certain events, such as (i) death or disability of the recipient,  (ii) certain circumstances in connection with a change of control of the Company, (iii) for executive officers, termination without cause (as defined in the agreement), and (iv) for executive officers, resignation for good reason (as defined). Total compensation expense related to these other long-term incentive awards was approximately $219,575 and $166,000 for the three months ended March 31, 2022 and 2021, respectively. As of March 31, 2022, there was a total of $1.0 million of unrecognized compensation expense related to these other long-term incentive awards which is expected to be recognized over the next 1.7 years.</span></div><span></span>

Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration that we expect to receive for those goods or services. To recognize revenue, we (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, we satisfy the performance obligation(s).

Under ASC 606, revenue is measured based on a consideration specified in a customer&#x2019;s contract, excluding any sale incentives and taxes collected on behalf of third parties (i.e. sales and property taxes). Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration that we expect to receive for those goods or services. To recognize revenue, we (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, we satisfy the performance obligation(s). Shipping and handling costs incurred are accounted for as fulfillment costs and are included in cost of revenues in our condensed consolidated statements of operations. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Nature of Goods and Services&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The following is a description of principal activities from which the Company generates its revenue: &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Rental Revenue.  &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;The Company generates revenue from renting compressors and flare systems to our customers.  These contracts, which all qualify as operating leases under ASC Topic 842, Leases (ASC 842), may also include a fee for servicing the compressor or flare during the rental contract period. Our rental contracts typically range from &lt;span style="-sec-ix-hidden:id3VybDovL2RvY3MudjEvZG9jOjBiYWFhNDliY2RiZjRkNDFiMGRjYzZhZmFjZWFiMGQ3L3NlYzowYmFhYTQ5YmNkYmY0ZDQxYjBkY2M2YWZhY2VhYjBkN18zNy9mcmFnOjcxMTUwODQzNDVlNzRlNDlhYjczNTk5NDg4ZjNiNDRlL3RleHRyZWdpb246NzExNTA4NDM0NWU3NGU0OWFiNzM1OTk0ODhmM2I0NGVfMzA5OQ_2308d91e-adbd-4bb6-b148-a52ee8210261"&gt;six&lt;/span&gt; to 24 months, with our larger horsepower compressors having contract terms of up to 60 months. Our revenue is recognized over time, with equal monthly payments over the term of the contract. After the terms of the contract have expired, a customer may renew their contract or continue renting on a monthly basis thereafter. In accordance ASC 842, we have applied the practical expedient ASC 842-10-15-42A, which allows the Company to combine lease and non-lease components.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%"&gt;Sales Revenue.  &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt;The Company generates revenue by the sale of custom/fabricated compressors, flare systems and parts, as well as, exchange/rebuilding customer owned compressors and sale of used rental equipment.  &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;Custom/fabricated compressors and flare systems&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; - The Company designs and fabricates compressors and flares based on the customer&#x2019;s specifications outlined in their contract. Though the equipment being built is customized by the customer, control under these contracts does not pass to the customer until the compressor or flare package is complete and shipped, or in accordance with a bill and hold arrangement, the customer accepts title and assumes the risk and rewards of ownership. We request some of our customers to make progressive payments as the product is being built; these payments are recorded as a contract liability on the Deferred Income line on the condensed consolidated balance sheet until control has been transferred. These contracts also may include an assurance warranty clause to guarantee the product is free from defects in material and workmanship for a set duration of time; this is a standard industry practice and is not considered a performance obligation. &lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:72pt;text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt;text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;From time to time we recognize revenue when manufacturing is complete and the equipment is ready for shipment. At the customer&#x2019;s request, we will bill the customer upon completing all performance obligations, but before shipment. The customer will formally request that we ship the equipment per their direction from our manufacturing facility at a later specified date and that we segregate the equipment from our finished goods, such that they are not available to fill other orders. Per the customer&#x2019;s agreement change of control is passed to the customer once the equipment is complete and ready for shipment. We have operated using bill and hold agreements with certain customers for many years, with consistent and satisfactory results for both the customer and us. The credit terms on these agreements are consistent with the credit terms on all other sales. All control is maintained by the customer and there are no exceptions to the customer&#x2019;s commitment to accept and pay for the manufactured equipment. There was no revenue recognized for bill and hold arrangements for the three months ended March 31, 2022 and 2021.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;Parts&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt; - &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Revenue is recognized after the customer obtains control of the parts. Control is passed either by the customer taking physical possession or the parts being shipped. The amount of revenue recognized is not adjusted for expected returns, as our historical part returns have been de minimis. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%;text-decoration:underline"&gt;Exchange or rebuilding customer owned compressors&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt; - Based on the contract, the Company will either exchange a new/rebuilt compressor for the customer&#x2019;s malfunctioning compressor or rebuild the customer&#x2019;s compressor. Revenue is recognized after control of the replacement compressor has transferred to the customer based on the terms of the contract, i.e., by physical delivery, delivery and installment, or shipment of the compressor.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%;text-decoration:underline"&gt;Used compressors or flares&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt; - From time to time, a customer may request to purchase a used compressor or flare out of our rental fleet.

Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  Valuation allowances are established to reduce deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized. To the extent we establish a valuation allowance or increase this allowance in a period, we include an expense in the tax provision in our condensed consolidated statements of operations.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We account for uncertain tax positions in accordance with guidance in ASC 740, which prescribes the minimum recognition threshold a tax position taken or expected to be taken in a tax return is required to meet before being recognized in the condensed consolidated financial statements. Tax benefits are recognized only for tax positions that are more likely than not to be sustained upon examination by tax authorities.  The amount recognized is measured as the largest amount of benefit that is greater than 50% likely to be realized upon settlement.  A liability for unrecognized tax benefits is recorded for any tax benefits claimed in our tax returns that do not meet these recognition and measurement standards.  We have no liabilities for uncertain tax positions as of March 31, 2022.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Our policy regarding income tax interest and penalties is to expense those items as interest expense and other expense, respectively.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:115%"&gt;Recently Issued Accounting Pronouncements&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (ASC Topic 326): Measurement of Credit Losses on Financial Instruments.

Under ASC 606, revenue is measured based on a consideration specified in a customer&#x2019;s contract, excluding any sale incentives and taxes collected on behalf of third parties (i.e. sales and property taxes). Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration that we expect to receive for those goods or services. To recognize revenue, we (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, we satisfy the performance obligation(s).

Our rental contracts typically range from &lt;span style="-sec-ix-hidden:id3VybDovL2RvY3MudjEvZG9jOjBiYWFhNDliY2RiZjRkNDFiMGRjYzZhZmFjZWFiMGQ3L3NlYzowYmFhYTQ5YmNkYmY0ZDQxYjBkY2M2YWZhY2VhYjBkN18zNy9mcmFnOjcxMTUwODQzNDVlNzRlNDlhYjczNTk5NDg4ZjNiNDRlL3RleHRyZWdpb246NzExNTA4NDM0NWU3NGU0OWFiNzM1OTk0ODhmM2I0NGVfMzA5OQ_2308d91e-adbd-4bb6-b148-a52ee8210261"&gt;six&lt;/span&gt; to 24 months, with our larger horsepower compressors having contract terms of up to 60 months. Our revenue is recognized over time, with equal monthly payments over the term of the contract. After the terms of the contract have expired, a customer may renew their contract or continue renting on a monthly basis thereafter. In accordance ASC 842, we have applied the practical expedient ASC 842-10-15-42A, which allows the Company to combine lease and non-lease components.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:115%"&gt;Sales Revenue.  &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt;The Company generates revenue by the sale of custom/fabricated compressors, flare systems and parts, as well as, exchange/rebuilding customer owned compressors and sale of used rental equipment.  &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;Custom/fabricated compressors and flare systems&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt; - The Company designs and fabricates compressors and flares based on the customer&#x2019;s specifications outlined in their contract. Though the equipment being built is customized by the customer, control under these contracts does not pass to the customer until the compressor or flare package is complete and shipped, or in accordance with a bill and hold arrangement, the customer accepts title and assumes the risk and rewards of ownership. We request some of our customers to make progressive payments as the product is being built; these payments are recorded as a contract liability on the Deferred Income line on the condensed consolidated balance sheet until control has been transferred. These contracts also may include an assurance warranty clause to guarantee the product is free from defects in material and workmanship for a set duration of time; this is a standard industry practice and is not considered a performance obligation. &lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:72pt;text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="margin-bottom:10pt;text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;From time to time we recognize revenue when manufacturing is complete and the equipment is ready for shipment. At the customer&#x2019;s request, we will bill the customer upon completing all performance obligations, but before shipment. The customer will formally request that we ship the equipment per their direction from our manufacturing facility at a later specified date and that we segregate the equipment from our finished goods, such that they are not available to fill other orders. Per the customer&#x2019;s agreement change of control is passed to the customer once the equipment is complete and ready for shipment. We have operated using bill and hold agreements with certain customers for many years, with consistent and satisfactory results for both the customer and us. The credit terms on these agreements are consistent with the credit terms on all other sales. All control is maintained by the customer and there are no exceptions to the customer&#x2019;s commitment to accept and pay for the manufactured equipment. There was no revenue recognized for bill and hold arrangements for the three months ended March 31, 2022 and 2021.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%;text-decoration:underline"&gt;Parts&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt; - &lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Revenue is recognized after the customer obtains control of the parts. Control is passed either by the customer taking physical possession or the parts being shipped. The amount of revenue recognized is not adjusted for expected returns, as our historical part returns have been de minimis. &lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%;text-decoration:underline"&gt;Exchange or rebuilding customer owned compressors&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt; - Based on the contract, the Company will either exchange a new/rebuilt compressor for the customer&#x2019;s malfunctioning compressor or rebuild the customer&#x2019;s compressor. Revenue is recognized after control of the replacement compressor has transferred to the customer based on the terms of the contract, i.e., by physical delivery, delivery and installment, or shipment of the compressor.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%;text-decoration:underline"&gt;Used compressors or flares&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt; - From time to time, a customer may request to purchase a used compressor or flare out of our rental fleet. Revenue from the sale of rental equipment is recognized when the control has passed to the customer based on the terms of the contract, i.e., when the customer has taken physical possession or the equipment has been shipped.&lt;/span&gt;&lt;/div&gt;&lt;div style="padding-left:72pt;text-align:justify"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;Service and Maintenance Revenue&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;. The Company provides routine or call-out services on customer owned equipment. Revenue is recognized after services in the contract are rendered. &lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Payment terms for sales revenue and service and maintenance revenue discussed above are generally 30 to 60 days, although terms for specific customers can vary. Also, transaction prices are not subject to variable consideration constraints.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%"&gt;Contract Costs&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;&#160;&#160;&#160;&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:90pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%"&gt;The Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period of the assets that the Company otherwise would have recognized is one year or less. These costs are included in selling, general and administrative expenses on our condensed consolidated statements of operations.&lt;/span&gt;&lt;/div&gt;</us-gaap:RevenueFromContractWithCustomerPolicyTextBlock>

Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  Valuation allowances are established to reduce deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized. To the extent we establish a valuation allowance or increase this allowance in a period, we include an expense in the tax provision in our condensed consolidated statements of operations.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;We account for uncertain tax positions in accordance with guidance in ASC 740, which prescribes the minimum recognition threshold a tax position taken or expected to be taken in a tax return is required to meet before being recognized in the condensed consolidated financial statements. Tax benefits are recognized only for tax positions that are more likely than not to be sustained upon examination by tax authorities.  The amount recognized is measured as the largest amount of benefit that is greater than 50% likely to be realized upon settlement.  A liability for unrecognized tax benefits is recorded for any tax benefits claimed in our tax returns that do not meet these recognition and measurement standards.  We have no liabilities for uncertain tax positions as of March 31, 2022.&lt;/span&gt;&lt;/div&gt;&lt;div&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%"&gt;Our policy regarding income tax interest and penalties is to expense those items as interest expense and other expense, respectively.&lt;/span&gt;&lt;/div&gt;</us-gaap:IncomeTaxPolicyTextBlock>

The CARES Act allowed NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid federal income taxes.  The Company generated significant NOLs during 2018 and 2019, and has filed amended returns to carryback these losses for five years. Accordingly, during 2020, the Company recorded a federal income tax receivable of $15.0&#160;million and an increase to its deferred income tax liability of $10.1&#160;million on its condensed consolidated balance sheet.  During the third quarter of 2020, the Company received refunds totaling $3.9&#160;million related to its 2018 NOLs, which reduced its federal income tax receivable to $11.5 million on its condensed consolidated balance sheet as of March 31, 2022.</us-gaap:IncomeTaxDisclosureTextBlock>

The Previous Credit Agreement had an aggregate commitment of $30 million, subject to collateral availability.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%"&gt;New Credit Agreement&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:103%"&gt;On May 11, 2021, we entered into a five year senior secured revolving credit agreement ("New Credit Agreement") with Texas Capital Bank, National Association (the "Lender") with an initial commitment of $20 million and an accordion feature that would increase the maximum commitment to $30 million, subject to collateral availability. We also have a right to request from the Lender, on an uncommitted basis, an increase of up to $30 million on the aggregate commitment; provided, however, the aggregate commitment amount is not permitted to exceed $50 million. The maturity date of the New Credit Agreement is May 11, 2026. The obligations under the New Credit Agreement are secured by a first priority lien on a variety of our assets, including inventory and accounts receivable as well as a variable number of our leased compressor equipment.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:103%"&gt;Borrowing Base.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:103%"&gt; At any time before the maturity of the New Credit Agreement, we may draw, repay and re-borrow amounts available under the borrowing base up to the maximum aggregate availability discussed above.

The Lender may adjust the borrowing base components if material deviations in the collateral are discovered in future audits of the collateral.

"Base Rate" means, for any day, a rate of interest per annum equal to the highest of (a) the prime rate for such day; (b) the sum of the federal funds rate for such day plus 0.50%; and (c) the Adjusted Eurodollar Rate for such day plus 1.00%. The Applicable Margin is determined based upon the leverage ratio as set forth in the most recent compliance certificate received by the Lender for each fiscal quarter from time to time pursuant to the New Credit Agreement. Depending on the leverage ratio, the Applicable Margin can be 0.25% to 0.75% for Base Rate Loans (as defined in the New Credit Agreement) and 1.25% to 1.75% for Eurodollar Rate Loans and for requested letters of credit. In addition, we are required to pay a monthly commitment fee on the daily average unused amount of the commitment while the New Credit Agreement is in effect at an annual rate equal to 0.25% of the unused commitment amount. Accrued interest is payable monthly on outstanding principal amounts and unused commitment fee, provided that accrued interest on Eurodollar Rate Loans is payable at the end of each interest period, but in no event less frequently than quarterly.&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span&gt;&lt;br/&gt;&lt;/span&gt;&lt;/div&gt;&lt;div style="text-align:justify;text-indent:36pt"&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:103%"&gt;Covenants.&lt;/span&gt;&lt;span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:103%"&gt; The New Credit Agreement contains customary representations and warranties, as well as covenants which, among other things, condition or limit our ability to incur additional indebtedness and liens; enter into transactions with affiliates; make acquisitions in excess of certain amounts; pay dividends; redeem or repurchase capital stock or senior notes; make investments or loans; make negative pledges; consolidate, merge or effect asset sales; or change the nature of our business.

vests in equal, annual tranches over 3 years beginning on the anniversary of the grant date. In addition, on March 18, 2021, we issued a $50,000 award to three of our independent members of our Board of Directors as partial payment for their services in 2021. On April 1, 2021, we issued a $50,000 award to a newly appointed independent member of our Board of Directors as partial payment for his services in 2021. These awards vest one year from the date of grant and are payable in cash upon vesting. There were no long-term incentive awards issued to executives of directors during the three months ended March 31, 2022. The Company accounts for these other long-term incentive awards as liabilities under accrued liabilities on our condensed consolidated balance sheet. The vesting of these awards awards is subject to acceleration upon certain events, such as (i) death or disability of the recipient,  (ii) certain circumstances in connection with a change of control of the Company, (iii) for executive officers, termination without cause (as defined in the agreement), and (iv) for executive officers, resignation for good reason (as defined). Total compensation expense related to these other long-term incentive awards was approximately $219,575 and $166,000 for the three months ended March 31, 2022 and 2021, respectively. As of March 31, 2022, there was a total of $1.0 million of unrecognized compensation expense related to these other long-term incentive awards which is expected to be recognized over the next 1.7 years.&lt;/span&gt;&lt;/div&gt;</us-gaap:DisclosureOfCompensationRelatedCostsShareBasedPaymentsTextBlock>
