Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation Our accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP and pursuant to the rules and regulations of the SEC. In the opinion of our management, such financial information reflects all normal recurring adjustments necessary for a fair presentation of these interim unaudited condensed consolidated financial statements in accordance with GAAP. Operating results for the three and nine months ended September 30, 2020 are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements contained in our annual report on Form 10-K for the year ended December 31, 2019 filed on February 18, 2020 (our “2019 Annual Report”). Use of Estimates Our unaudited condensed consolidated financial statements have been prepared in conformity with GAAP, which includes the use of estimates and assumptions by management that affect the reported amounts of assets, liabilities, revenues, expenses and disclosure of contingent assets and liabilities that existed at the date of the unaudited condensed consolidated financial statements. Although these estimates were based on management’s available knowledge of current and expected future events, actual results could differ from these estimates. Significant Accounting Policies Cash and Cash Equivalents Cash and cash equivalents consist of all cash balances. We consider investments in highly liquid financial instruments purchased with an original maturity of 90 days or less to be cash equivalents. Trade Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Allowance for Credit Losses In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (“Topic 326”): Measurement of Credit Losses on Financial Instruments . On January 1, 2020, we adopted Topic 326 using the modified retrospective approach, which was effective for interim and annual reporting periods beginning on or after December 15, 2019. Topic 326 requires immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. To adopt Topic 326, we evaluated our allowance for credit losses related to our two financial assets measured at amortized cost: (i) trade accounts receivable and (ii) net investment in lease related to our sales-type lease discussed further in Note 7. Due to the short-term nature of our trade accounts receivable, we consider the amortized cost to be the same as the carrying amount of the receivable, excluding the allowance for credit losses. There was no cumulative effect adjustment to partners’ capital upon adoption. Our determination of the allowance for credit losses requires us to make estimates and judgments regarding our customers’ ability to pay amounts due and is the same process for both of our financial assets as they have similar risk characteristics. We continuously evaluate the financial strength of our customers based on collection experience, the overall business climate in which our customers operate and specific identification of customer credit losses and make adjustments to the allowance as necessary. Our evaluation of our customers’ financial strength is based on the aging of their respective receivables balance, customer correspondence, financial information and third-party credit ratings. Our evaluation of the business climate in which our customers operate is based on a review of various publicly available materials regarding our customers’ industries, including the solvency of various companies in the industry. Inventories Inventories consist of serialized and non-serialized parts used primarily on compression units. All inventories are stated at the lower of cost or net realizable value. Serialized parts inventories are determined using the specific identification cost method, while non-serialized parts inventories are determined using the weighted average cost method. Purchases of inventories are considered operating activities on the unaudited condensed consolidated statements of cash flows. Property and Equipment Property and equipment are carried at cost except for (i) certain acquired assets which are recorded at fair value on their respective acquisition dates and (ii) impaired assets which are recorded at fair value on the last impairment evaluation date for which an adjustment was required. Overhauls and major improvements that increase the value or extend the life of compression equipment are capitalized and depreciated over three When property and equipment is retired or sold, its carrying value and the related accumulated depreciation are removed from our accounts and any associated gains or losses are recorded on our statements of operations in the period of sale or disposition. Capitalized interest is calculated by multiplying the Partnership’s monthly effective interest rate on outstanding debt by the amount of qualifying costs, which include upfront payments to acquire certain compression units. Capitalized interest was $6,000 and $0.2 million for the three and nine months ended September 30, 2020, respectively, and $0.1 million and $0.5 million for the three and nine months ended September 30, 2019 , respectively. Impairment of Long-Lived Assets Long-lived assets with recorded values that are not expected to be recovered through future cash flows are written-down to estimated fair value. We test long-lived assets for impairment when events or circumstances indicate that the assets’ carrying value may not be recoverable or will no longer be utilized in the operating fleet. The most common circumstance requiring compression units to be evaluated for impairment is when idle units do not meet the desired performance characteristics of our active revenue generating horsepower. The carrying value of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying value of the long-lived asset exceeds the sum of the undiscounted cash flows associated with the asset, an impairment loss equal to the amount of the carrying value exceeding the fair value of the asset is recognized. The fair value of the asset is measured using quoted market prices or, in the absence of quoted market prices, based on an estimate of discounted cash flows, the expected net sale proceeds compared to the other similarly configured fleet units we recently sold or a review of other units recently offered for sale by third parties, or the estimated component value of the equipment we plan to use. Refer to Note 5 for more detailed information about impairment charges during the three and nine months ended September 30, 2020 and 2019. Identifiable Intangible Assets Identifiable intangible assets are recorded at cost and amortized using the straight-line method over their estimated useful lives, which is the period over which the assets are expected to contribute directly or indirectly to our future cash flows. The estimated useful lives of our intangible assets range from 15 to 25 years. Goodwill Goodwill represents consideration paid in excess of the fair value of the identifiable net assets acquired in a business combination. Goodwill is not amortized, but is reviewed for impairment annually based on the carrying values as of October 1, or more frequently if impairment indicators arise that suggest the carrying value of goodwill may not be recovered. Refer to Note 5 for more detailed information about goodwill impairment charges during the nine months ended September 30, 2020. Revenue Recognition Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally this occurs with the transfer of our services or goods. Revenue is measured at the amount of consideration we expect to receive in exchange for providing services or transferring goods. Incidental items, if any, that are immaterial in the context of the contract are recognized as expenses. Income Taxes We are organized as a partnership for U.S. federal and state income tax purposes. As a result, our partners are responsible for U.S. federal and state income taxes based upon their distributive share of our items of income, gain, loss or deduction. Texas imposes an entity-level income tax on partnerships that is based on Texas sourced taxable margin (the “Texas Margin Tax”). We have included in the unaudited condensed consolidated financial statements a provision for the Texas Margin Tax. Pass Through Taxes Sales taxes incurred on behalf of, and passed through to, customers are accounted for on a net basis. Fair Value Measurements Accounting standards on fair value measurements establish a framework for measuring fair value and stipulate disclosures about fair value measurements. The standards apply to recurring and non-recurring financial and non-financial assets and liabilities that require or permit fair value measurements. Among the required disclosures is the fair value hierarchy of inputs we use to value an asset or a liability. The three levels of the fair value hierarchy are described as follows: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access at the measurement date. Level 2 inputs are those other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. As of September 30, 2020, our financial instruments consisted primarily of cash and cash equivalents, trade accounts receivable, trade accounts payable and long-term debt. The book values of cash and cash equivalents, trade accounts receivable and trade accounts payable are representative of fair value due to their short-term maturities. The carrying amount of our revolving credit facility approximates fair value due to the floating interest rates associated with the debt. The fair value of our Senior Notes 2026 and Senior Notes 2027 were estimated using quoted prices in inactive markets and are considered Level 2 measurements. The following table summarizes the aggregate principal amount and fair value of our Senior Notes 2026 and Senior Notes 2027 (in thousands): ​ September 30, December 31, Senior Notes 2026, aggregate principal $ 725,000 $ 725,000 Fair value of Senior Notes 2026 725,000 764,875 Senior Notes 2027, aggregate principal $ 750,000 $ 750,000 Fair value of Senior Notes 2027 746,250 785,625 Operating Segment We operate in a single business segment, the compression services business.

Trade Accounts Receivable	Trade Accounts Receivable The allowance for credit losses, which was $5.2 million and $2.5 million as of September 30, 2020 and December 31, 2019, respectively, is our best estimate of the amount of probable credit losses included in our existing accounts receivable. The following summarizes activity within our trade accounts receivable allowance for credit losses balance (in thousands): Allowance for Credit Losses Balance as of December 31, 2019 $ 2,479 Current-period provision for expected credit losses (1) 3,700 Writeoffs charged against the allowance (975) Balance as of September 30, 2020 $ 5,204 ______________________ (1) There was no provision for expected credit losses recognized during the three months ended September 30, 2020. Low crude oil prices, driven by decreased demand for and global oversupply of crude oil as a result of the COVID-19 pandemic, is the primary factor contributing to the increase to the allowance for credit losses for the nine months ended September 30, 2020. We cannot predict the duration of these conditions or the severity of their impact on our customers and the collectability of their accounts receivable.

On a quarterly basis, we evaluate the future deployment of our idle fleet under current market conditions. For the three and nine months ended September 30, 2020, we determined to retire 16 and 27 compressor units, respectively, for a total of approximately 3,900 and 9,000 horsepower, respectively, that were previously used to provide compression services in our business. As a result, we recorded impairments of compression equipment of $1.7 million and $5.6 million for the three and nine months ended September 30, 2020, respectively. For the nine months ended September 30, 2019, we determined to retire 14 compressor units, for a total of approximately 4,700 horsepower, that were previously used to provide compression services in our business. As a result, we recorded an impairment of compression equipment of $3.2 million for the nine months ended September 30, 2019. The primary causes for these impairments were: (i) units were not considered marketable in the foreseeable future, (ii) units were subject to excessive maintenance costs or (iii) units were unlikely to be accepted by customers due to certain performance characteristics of the unit, such as the inability to meet current quoting criteria without excessive retrofitting costs. These compression units were written down to their respective estimated salvage values, if any. No impairment was recorded for the three months ended September 30, 2019. Identifiable Intangible Assets Identifiable intangible assets, net consisted of the following (in thousands): ​ Customer Relationships Trade Names Total Net balance as of December 31, 2019 $ 329,057 $ 34,114 $ 363,171 Amortization expense (19,578) (2,457) (22,035) Net balance as of September 30, 2020 $ 309,479 $ 31,657 $ 341,136 Accumulated amortization of intangible assets was $209.5 million and $187.5 million as of September 30, 2020 and December 31, 2019, respectively. The expected amortization of the intangible assets for each of the five succeeding years is $29.4 million. Goodwill During the first quarter of 2020 certain potential impairment indicators were identified, specifically (i) the decline in the market price of our common units, (ii) the decline in global commodity prices and (iii) the COVID-19 pandemic; which together indicated the fair value of the reporting unit was less than its carrying amount as of March 31, 2020. We performed a quantitative goodwill impairment test as of March 31, 2020 and determined fair value using a weighted combination of the income approach and the market approach. Determining fair value of a reporting unit requires judgment and use of significant estimates and assumptions. Such estimates and assumptions include revenue growth rates, EBITDA margins, weighted average costs of capital and future market conditions, among others. We believe the estimates and assumptions used were reasonable and based on available market information, but variations in any of the assumptions could have resulted in materially different calculations of fair value and determinations of whether or not an impairment is indicated. Under the income approach, we determined fair value based on estimated future cash flows, including estimates for capital expenditures, discounted to present value using the risk-adjusted industry rate, which reflects the overall level of inherent risk of the Partnership. Cash flow projections were derived from four-year operating forecasts plus an estimate of later period cash flows, all of which were developed by management. Subsequent period cash flows were developed using growth rates that management believed were reasonably likely to occur. Under the market approach, we determined fair value by applying valuation multiples of comparable publicly-traded companies to the projected EBITDA of the Partnership and then averaging that estimate with similar historical calculations using a three-year average. In addition, we estimated a reasonable control premium representing the incremental value that would accrue to us if we were to be acquired. Based on the quantitative goodwill impairment test described above, our carrying amount exceeded fair value and as a result, we recognized a goodwill impairment of $619.4 million for the three months ended March 31, 2020.

Leases [Abstract]
Lease Accounting	Lease Accounting Lessee Accounting We maintain both finance leases and operating leases, primarily related to office space, warehouse facilities and certain corporate equipment. Our leases have remaining lease terms of up to ten years, some of which include options that permit renewals for additional periods. We determine if an arrangement is a lease at inception. Operating leases are included in lease right-of-use assets, accrued liabilities and operating lease liabilities in our unaudited condensed consolidated balance sheets. Finance leases are included in property and equipment, accrued liabilities and other liabilities in our unaudited condensed consolidated balance sheets. Right-of-use (“ROU”) lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU lease assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available on the commencement date in determining the present value of lease payments. ROU lease assets also include any lease payments made and exclude lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Variable costs such as our proportionate share of actual costs for utilities, common area maintenance, property taxes and insurance are not included in the lease liability and are recognized in the period in which they are incurred. For short-term leases (leases that have terms of twelve months or less upon commencement), lease payments are recognized on a straight line basis and no ROU assets are recorded. For certain equipment leases, such as office equipment, we account for the lease and non-lease components as a single lease component.

Lessor Accounting​ We granted a bargain purchase option to a customer with respect to certain compressor packages leased to the customer. The bargain purchase option provides the customer with an option to acquire the equipment at a value significantly less than the fair market value at the end of the lease term in 2021. We accounted for this option as a sales-type lease resulting in a current installment receivable included in other accounts receivable of $4.0 million and $4.0 million, and a long-term installment receivable included in other assets of $0 and $2.9 million as of September 30, 2020 and December 31, 2019, respectively. As of September 30, 2020, there is no allowance for credit losses on our net investment in the sales-type lease based on our collections experience with the customer.

The Credit Agreement has an aggregate commitment of $1.6 billion (subject to availability under our borrowing base), with a further potential increase of $400 million, and has a maturity date of April 2, 2023, which we expect to maintain for the term. As of September 30, 2020, we had outstanding borrowings under the Credit Agreement of $496.9 million, $1.1 billion of borrowing base availability and, subject to compliance with the applicable financial covenants, available borrowing capacity of $411.8 million. Our weighted average interest rate in effect for all borrowings under the Credit Agreement as of September 30, 2020 was 3.03%, with a weighted average interest rate of 3.36% for the nine months ended September 30, 2020. There were no letters of credit issued as of September 30, 2020. We pay a commitment fee of 0.375% on the unused portion of the Credit Agreement. The Credit Agreement was amended on August 3, 2020 (the “Amendment Effective Date”) and amends, among other things, the requirements of certain covenants and the date on which certain covenants in the Credit Agreement must be met from the Amendment Effective Date until the last day of the fiscal quarter ending December 31, 2021 (the “Covenant Relief Period”). The Credit Agreement permits us to make distributions of available cash to unitholders so long as (i) no default under the facility has occurred, is continuing or would result from the distribution, (ii) immediately prior to and after giving effect to such distribution, we are in compliance with the facility’s financial covenants and (iii) immediately after giving effect to such distribution, we have availability under the Credit Agreement of at least $250 million (reverting back to $100 million after the Covenant Relief Period). The Credit Agreement also contains various financial covenants, including covenants requiring us to maintain: • a minimum EBITDA to interest coverage ratio of 2.5 to 1.0, determined as of the last day of each fiscal quarter, for the annualized trailing three months; and • a maximum funded debt to EBITDA ratio, determined as of the last day of each fiscal quarter, for the annualized trailing three months of (i) 5.75 to 1.00 for the fiscal quarters ending September 30, 2020 and December 31, 2020, (ii) 5.50 to 1.00 for the fiscal quarters ending March 31, 2021 and June 30, 2021 and (iii) 5.25 to 1.00 for the fiscal quarters ending September 30, 2021 and December 31, 2021 (reverting back to 5.00 to 1.00 after the Covenant Relief Period). In addition, the amendment provides that the 0.5 increase in maximum funded debt to EBITDA ratio applicable to certain future acquisitions (for the six In addition, during the Covenant Relief Period, the applicable margin for Eurodollar borrowings is increased from a range of 2.00% – 2.75% to a range of 2.25% – 3.00%. The amendment further provides that the Partnership becomes guarantor of the obligations of all other guarantors under the Credit Agreement. In connection with the Credit Agreement amendment, we incurred arrangement fees, consent fees and other fees in the amount of $3.4 million, which were capitalized to loan costs and are amortized over the remaining term of the Credit Agreement. The Credit Agreement is a “revolving credit facility” that includes a lock box arrangement, whereby remittances from customers are forwarded to a bank account controlled by the administrative agent and are applied to reduce borrowings under the facility. Senior Notes 2026​ On March 23, 2018, the Partnership and its wholly owned finance subsidiary, USA Compression Finance Corp. (“Finance Corp”), co-issued the Senior Notes 2026. The Senior Notes 2026 accrue interest at the rate of 6.875% per year. Interest on the Senior Notes 2026 is payable semi-annually in arrears on each of April 1 and October 1. The indenture governing the Senior Notes 2026 (the “2026 Indenture”) contains certain financial ratios that we must comply with in order to make certain restricted payments as described in the 2026 Indenture. As of September 30, 2020, we were in compliance with such financial covenants under the 2026 Indenture.

The Senior Notes 2026 and the 2026 Guarantees are general unsecured obligations and rank equally in right of payment with all of the Guarantors’ and our existing and future senior indebtedness and senior to the Guarantors’ and our future subordinated indebtedness, if any. The Senior Notes 2026 and the 2026 Guarantees are effectively subordinated in right of payment to all of the Guarantors’ and our existing and future secured debt, including debt under the Credit Agreement and guarantees thereof, to the extent of the value of the assets securing such debt, and are structurally subordinated to all indebtedness of any of our subsidiaries that do not guarantee the Senior Notes 2026. Senior Notes 2027 On March 7, 2019, the Partnership and Finance Corp co-issued the Senior Notes 2027. The Senior Notes 2027 accrue interest from March 7, 2019 at the rate of 6.875% per year. Interest on the Senior Notes 2027 is payable semi-annually in arrears on each of March 1 and September 1. The indenture governing the Senior Notes 2027 (the “2027 Indenture”) contains certain financial ratios that we must comply with in order to make certain restricted payments as described in the 2027 Indenture. As of September 30, 2020, we were in compliance with such financial covenants under the 2027 Indenture. The Senior Notes 2027 are fully and unconditionally guaranteed (the “2027 Guarantees”), jointly and severally, on a senior unsecured basis by the Guarantors. The Senior Notes 2027 and the 2027 Guarantees are general unsecured obligations and rank equally in right of payment with all of the Guarantors’ and our existing and future senior indebtedness and senior to the Guarantors’ and our future subordinated indebtedness, if any. The Senior Notes 2027 and the 2027 Guarantees are effectively subordinated in right of payment to all of the Guarantors’ and our existing and future secured debt, including debt under the Credit Agreement and guarantees thereof, to the extent of the value of the assets securing such debt, and are structurally subordinated to all indebtedness of any of our subsidiaries that do not guarantee the Senior Notes 2027. We have no assets or operations independent of our subsidiaries, and there are no significant restrictions upon our ability to obtain funds from our subsidiaries by dividend or loan. Each of the Guarantors is 100% owned by us. None of the assets of our subsidiaries represent restricted net assets pursuant to Rule 4-08(e)(3) of Regulation S-X under the Securities Act.

Class B Unit Conversion On July 30, 2019, 6,397,965 Class B Units automatically converted into common units on a one-for-one basis, resulting in the issuance of 6,397,965 common units to ETO. Following the conversion, there are no longer Class B Units outstanding. Cash Distributions We have declared and paid quarterly distributions per unit to our limited partner unitholders of record, including holders of our common units and phantom units, as follows (dollars in millions, except distribution per unit): Payment Date Distribution per Limited Partner Unit Amount Paid to Common Unitholders Amount Paid to Phantom Unitholders Total Distribution February 8, 2019 $ 0.525 $ 47.2 $ 0.7 $ 47.9 May 10, 2019 0.525 47.3 0.6 47.9 August 9, 2019 0.525 47.4 0.6 48.0 November 8, 2019 0.525 50.7 0.6 51.3 2019 total distributions $ 2.10 $ 192.6 $ 2.5 $ 195.1 February 7, 2020 $ 0.525 $ 50.7 $ 0.9 $ 51.6 May 8, 2020 0.525 50.8 0.9 51.7 August 10, 2020 0.525 50.9 0.8 51.7 2020 total distributions $ 1.575 $ 152.4 $ 2.6 $ 155.0 Announced Quarterly Distribution On October 15, 2020, we announced a cash distribution of $0.525 per unit on our common units. The distribution will be paid on November 6, 2020 to common unitholders of record as of the close of business on October 26, 2020. DRIP During the nine months ended September 30, 2020, distributions of $1.4 million were reinvested under the DRIP resulting in the issuance of 140,318 common units. Warrants As of September 30, 2020 and December 31, 2019, we had two tranches of warrants outstanding, which includes warrants to purchase (i) 5,000,000 common units with a strike price of $17.03 per common unit and (ii) 10,000,000 common units with a strike price of $19.59 per common unit (collectively, the “Warrants”). The Warrants may be exercised by the holders at any time before April 2, 2028. Earnings (Loss) per Unit The computation of earnings (loss) per unit is based on the weighted average number of participating securities outstanding during the applicable period. Basic earnings (loss) per unit is determined by dividing net income (loss) allocated to participating securities after deducting the distributions on Preferred Units, by the weighted average number of participating securities outstanding during the period. Net income (loss) attributable to unitholders is allocated to participating securities based on their respective shares of the distributed and undistributed earnings for the period. To the extent cash distributions exceed net income (loss) attributable to unitholders for the period, the excess distributions are allocated to all participating securities outstanding based on their respective ownership percentages. Diluted earnings (loss) per unit are computed using the treasury stock method, which considers the potential issuance of limited partner units associated with our long-term incentive plan and Warrants. The classes of participating securities include common units, Class B Units prior to July 30, 2019, and certain equity-based compensation awards. Unvested phantom units and unexercised Warrants are not included in basic earnings per unit, as they are not considered to be participating securities, but are included in the calculation of diluted earnings per unit to the extent they are dilutive, and in the case of Warrants to the extent they are considered “in the money.” For the three and nine months ended September 30, 2020, approximately 584,000 and 542,000 incremental unvested phantom units, respectively, were excluded from the calculation of diluted earnings per common unit because the impact was anti-dilutive and our outstanding Warrants are not included in the computation as they are not considered “in the money” for either period. For the three and nine months ended September 30, 2019, approximately 221,000 and 169,000 incremental unvested phantom units, respectively, represented the difference between our basic and diluted weighted average common units

Commitments and Contingencies	Commitments and Contingencies​ (a) Major Customers​ We did not have revenue from any single customer representing 10% or more of total revenue for the three and nine months ended September 30, 2020 or 2019. (b) Litigation​ From time to time, we and our subsidiaries may be involved in various claims and litigation arising in the ordinary course of business. In management’s opinion, the resolution of such matters is not expected to have a material adverse effect on our consolidated financial position, results of operations or cash flows. (c) Equipment Purchase Commitments​ Our future capital commitments are comprised of binding commitments under purchase orders for new compression units and serialized parts ordered but not received. Those commitments as of September 30, 2020 were $6.3 million, which we expect to settle in 2020. (d) Sales Tax Contingencies Our compliance with state and local sales tax regulations is subject to audit by various taxing authorities. The Office of the Texas Comptroller of Public Accounts (“Comptroller”) has claimed that specific operational processes, which we and others in our industry regularly conduct, result in transactions that are subject to state sales taxes. We and other companies in our industry have disputed these claims based on existing tax statutes which provide for manufacturing exemptions on the transactions in question. The manufacturing exemptions are based on the fact that our natural gas compression equipment is used in the process of preparing natural gas for ultimate use and sale. As of September 30, 2020, we have recorded a $44.9 million accrued liability and $44.9 million related party receivable from ETO related to open audits with the Comptroller. During January 2020, we entered into a compromise and settlement agreement with the Comptroller for the audit of the USA Compression Predecessor for the period from August 2006 to December 2007 for $4.0 million, which was paid by the USA Compression Predecessor’s former owner in February 2020.

Basis of Presentation and Sum_2

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2020
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates Our unaudited condensed consolidated financial statements have been prepared in conformity with GAAP, which includes the use of estimates and assumptions by management that affect the reported amounts of assets, liabilities, revenues, expenses and disclosure of contingent assets and liabilities that existed at the date of the unaudited condensed consolidated financial statements. Although these estimates were based on management’s available knowledge of current and expected future events, actual results could differ from these estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of all cash balances. We consider investments in highly liquid financial instruments purchased with an original maturity of 90 days or less to be cash equivalents.
Trade Accounts Receivable	Trade Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest.
Allowance for Credit Losses	Allowance for Credit Losses In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (“Topic 326”): Measurement of Credit Losses on Financial Instruments . On January 1, 2020, we adopted Topic 326 using the modified retrospective approach, which was effective for interim and annual reporting periods beginning on or after December 15, 2019. Topic 326 requires immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. To adopt Topic 326, we evaluated our allowance for credit losses related to our two financial assets measured at amortized cost: (i) trade accounts receivable and (ii) net investment in lease related to our sales-type lease discussed further in Note 7. Due to the short-term nature of our trade accounts receivable, we consider the amortized cost to be the same as the carrying amount of the receivable, excluding the allowance for credit losses. There was no cumulative effect adjustment to partners’ capital upon adoption. Our determination of the allowance for credit losses requires us to make estimates and judgments regarding our customers’ ability to pay amounts due and is the same process for both of our financial assets as they have similar risk characteristics. We continuously evaluate the financial strength of our customers based on collection experience, the overall business climate in which our customers operate and specific identification of customer credit losses and make adjustments to the allowance as necessary. Our evaluation of our customers’ financial strength is based on the aging of their respective receivables balance, customer correspondence, financial information and third-party credit ratings. Our evaluation of the business climate in which our customers operate is based on a review of various publicly available materials regarding our customers’ industries, including the solvency of various companies in the industry.
Inventories	Inventories Inventories consist of serialized and non-serialized parts used primarily on compression units. All inventories are stated at the lower of cost or net realizable value. Serialized parts inventories are determined using the specific identification cost method, while non-serialized parts inventories are determined using the weighted average cost method. Purchases of inventories are considered operating activities on the unaudited condensed consolidated statements of cash flows.
Property and Equipment	Property and Equipment Property and equipment are carried at cost except for (i) certain acquired assets which are recorded at fair value on their respective acquisition dates and (ii) impaired assets which are recorded at fair value on the last impairment evaluation date for which an adjustment was required. Overhauls and major improvements that increase the value or extend the life of compression equipment are capitalized and depreciated over three When property and equipment is retired or sold, its carrying value and the related accumulated depreciation are removed from our accounts and any associated gains or losses are recorded on our statements of operations in the period of sale or disposition. Capitalized interest is calculated by multiplying the Partnership’s monthly effective interest rate on outstanding debt by the amount of qualifying costs, which include upfront payments to acquire certain compression units. Capitalized interest was $6,000 and $0.2 million for the three and nine months ended September 30, 2020, respectively, and $0.1 million and $0.5 million for the three and nine months ended September 30, 2019 , respectively.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Long-lived assets with recorded values that are not expected to be recovered through future cash flows are written-down to estimated fair value. We test long-lived assets for impairment when events or circumstances indicate that the assets’ carrying value may not be recoverable or will no longer be utilized in the operating fleet. The most common circumstance requiring compression units to be evaluated for impairment is when idle units do not meet the desired performance characteristics of our active revenue generating horsepower. The carrying value of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying value of the long-lived asset exceeds the sum of the undiscounted cash flows associated with the asset, an impairment loss equal to the amount of the carrying value exceeding the fair value of the asset is recognized. The fair value of the asset is measured using quoted market prices or, in the absence of quoted market prices, based on an estimate of discounted cash flows, the expected net sale proceeds compared to the other similarly configured fleet units we recently sold or a review of other units recently offered for sale by third parties, or the estimated component value of the equipment we plan to use. Refer to Note 5 for more detailed information about impairment charges during the three and nine months ended September 30, 2020 and 2019.
Identifiable Intangible Assets	Identifiable Intangible Assets Identifiable intangible assets are recorded at cost and amortized using the straight-line method over their estimated useful lives, which is the period over which the assets are expected to contribute directly or indirectly to our future cash flows. The estimated useful lives of our intangible assets range from 15 to 25 years.
Goodwill	Goodwill Goodwill represents consideration paid in excess of the fair value of the identifiable net assets acquired in a business combination. Goodwill is not amortized, but is reviewed for impairment annually based on the carrying values as of October 1, or more frequently if impairment indicators arise that suggest the carrying value of goodwill may not be recovered. Refer to Note 5 for more detailed information about goodwill impairment charges during the nine months ended September 30, 2020.
Revenue Recognition	Revenue Recognition Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally this occurs with the transfer of our services or goods. Revenue is measured at the amount of consideration we expect to receive in exchange for providing services or transferring goods. Incidental items, if any, that are immaterial in the context of the contract are recognized as expenses.
Income Taxes	Income Taxes We are organized as a partnership for U.S. federal and state income tax purposes. As a result, our partners are responsible for U.S. federal and state income taxes based upon their distributive share of our items of income, gain, loss or deduction. Texas imposes an entity-level income tax on partnerships that is based on Texas sourced taxable margin (the “Texas Margin Tax”). We have included in the unaudited condensed consolidated financial statements a provision for the Texas Margin Tax.
Pass Through Taxes	Pass Through Taxes Sales taxes incurred on behalf of, and passed through to, customers are accounted for on a net basis.
Fair Value Measurements	Fair Value Measurements Accounting standards on fair value measurements establish a framework for measuring fair value and stipulate disclosures about fair value measurements. The standards apply to recurring and non-recurring financial and non-financial assets and liabilities that require or permit fair value measurements. Among the required disclosures is the fair value hierarchy of inputs we use to value an asset or a liability. The three levels of the fair value hierarchy are described as follows: Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access at the measurement date. Level 2 inputs are those other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. As of September 30, 2020, our financial instruments consisted primarily of cash and cash equivalents, trade accounts receivable, trade accounts payable and long-term debt. The book values of cash and cash equivalents, trade accounts receivable and trade accounts payable are representative of fair value due to their short-term maturities. The carrying amount of our revolving credit facility approximates fair value due to the floating interest rates associated with the debt. The fair value of our Senior Notes 2026 and Senior Notes 2027 were estimated using quoted prices in inactive markets and are considered Level 2 measurements.
Operating Segment	Operating Segment We operate in a single business segment, the compression services business.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2019, FASB issued ASU 2020-04, Reference Rate Reform (“Topic 848”): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendment to Topic 848 provides relief from certain contract modification accounting requirements for the transition away from LIBOR and certain other reference rates. Adoption of the amendments in this update are optional, effective upon issuance and may be adopted during any interim or annual period through December 31, 2022. We are currently evaluating the impact, if any, of the amendments to Topic 848 on our consolidated financial statements.
