Formation of the Partnership	Dec. 31, 2019
Notes to Financial Statements [Abstract]
Formation of the Partnership and Description of Business	ORGANIZATION AND OPERATIONS CSI Compressco LP, a Delaware limited partnership, is a provider of compression services and equipment for natural gas and oil production, gathering, artificial lift, transmission, processing, and storage. We also provide aftermarket services and compressor package parts and components manufactured by third-party suppliers. We provide these compression services and equipment to a broad base of natural gas and oil exploration and production, midstream, and transmission companies operating throughout many of the onshore producing regions of the U.S. as well as in a number of international locations, including the countries of Mexico, Canada, and Argentina. Previously, our equipment sales business included our new unit sales business that consisted of the fabrication and sale of new standard and custom-designed, engineered compressor packages fabricated primarily at our facility in Midland, Texas that were used to provide compression services or sold to our customers. In the fourth quarter of 2020, we fully exited the new unit sales business and we have reflected these operations as discontinued operations for all periods presented. See Note 9 - “Discontinued Operations.” Used equipment sales revenue continues to be included in equipment sales revenue. Unless the context requires otherwise, when we refer to “the Partnership,” “we,” “us,” and “our,” we are describing CSI Compressco LP and its wholly owned subsidiaries.

Summary of Significant Accounting Policies	Dec. 31, 2020
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation Our consolidated financial statements include the accounts of our wholly owned subsidiaries. All intercompany balances and transactions have been eliminated. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclose contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues, expenses, and impairments during the reporting period. Actual results could differ from those estimates, and such differences could be material. Reclassifications Certain previously reported financial information has been reclassified to conform to the current year’s presentation. For a discussion of the reclassification of the financial presentation of our new unit sales business as discontinued operations, see Note 9 - “Discontinued Operations.” Unless otherwise noted, amounts and disclosures throughout these Notes to Consolidated Financial Statements relate solely to continuing operations and exclude all discontinued operations. Cash Equivalents We consider all highly liquid cash investments with maturities of three months or less when purchased to be cash equivalents. Financial Instruments Financial instruments that subject us to concentrations of credit risk consist principally of trade accounts receivable, which are primarily due from companies of varying size engaged in oil and gas activities in the United States, Canada, Mexico, and Argentina. Our policy is to review the financial condition of customers before extending credit and periodically update customer credit information. Payment terms are on a short-term basis. The risk of loss from the inability to collect trade receivables is heightened during prolonged periods of low oil and natural gas commodity prices. We have currency exchange rate risk exposure related to transactions denominated in a foreign currency as well as to investments in certain of our international operations. Our risk management activities include the use of foreign currency forward purchase and sale derivative contracts as part of a program designed to mitigate the currency exchange rate risk exposure on selected international operations. We have no balance outstanding under our variable rate revolving credit facility as of December 31, 2020 and face market risk exposure related to changes in applicable interest rates when balances are outstanding. Significant Customers During the years ended December 31, 2020, 2019 and 2018 , one individual customer accounted for 10% or more of our revenues. As of December 31, 2020 and 2019, no receivables from individual customers represented 10% or more of our consolidated trade accounts receivable net of allowance for doubtful accounts. Foreign Currencies We have designated the Canadian dollar as the functional currency for our operations in Canada. We are exposed to fluctuations between the U.S. dollar and certain foreign currencies, including the Canadian dollar, the Mexican peso, and the Argentine peso, as a result of our international operations. Foreign currency exchange gains are included in other (income) expense, net, and totaled $0.5 million, $2.6 million, and $1.4 million during the years ended December 31, 2020, 2019, and 2018, respectively. On June 30, 2018, we determined the economy in Argentina to be highly inflationary. As a result of this determination and in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”), on July 1, 2018, the functional currency of our operations in Argentina was changed from the Argentine peso to the U.S. dollar. The remeasurement did not have a material impact on our consolidated financial position or results of operations. Leases As a lessee, unless the lease meets the criteria of short-term and is excluded per our policy election described below, we initially recognize a lease liability and related right-of-use asset on the commencement date. The right-of-use asset represents our right to use an underlying asset and the lease liability represents our obligation to make lease payments to the lessor over the lease term. All of our long-term leases are operating leases and are included in operating lease right-of-use assets, accrued liabilities and other, and operating lease liabilities in our consolidated balance sheet as of December 31, 2020 and 2019. We determine whether a contract is or contains a lease at inception of the contract. Where we are a lessee in a contract that includes an option to extend or terminate the lease, we include the extension period or exclude the period covered by the termination option in our lease term in determining the right-of-use asset and lease liability, if it is reasonably certain that we would exercise the option. As an accounting policy election, we do not include short-term leases on our balance sheet. Short-term leases include leases with a term of 12 months or less, inclusive of renewal options we are reasonably certain to exercise. The lease payments for short-term leases are included as operating lease costs on a straight-line basis over the lease term in cost of revenues or selling, general, and administrative expense based on the use of the underlying asset. We recognize lease costs for variable lease payments not included in the determination of a lease liability in the period in which an obligation is incurred. As allowed by U.S. GAAP, we do not separate nonlease components from the associated lease component for our compression services contracts and instead account for those components as a single component based on the accounting treatment of the predominant component. In our evaluation of whether Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 842 “Leases” or ASC 606 “Revenue from Contracts with Customers” is applicable to the combined component based on the predominant component, we determined the services nonlease component is predominant, resulting in the ongoing recognition of our compression services contracts following ASC 606. Our operating leases are recognized at the present value of lease payments over the lease term. When the implicit discount rate is not readily determinable, we use our incremental borrowing rate to calculate the discount rate used to determine the present value of lease payments. Consistent with other long-lived assets or asset groups that are held and used, we test for impairment of our right-of-use assets when impairment indicators are present. Allowance for Doubtful Accounts The allowance for doubtful accounts is determined on a specific identification basis when we believe that the collection of specific amounts owed to us is not probable. Changes in the allowance are as follows: Year Ended December 31, 2020 2019 2018 (In Thousands) At beginning of period $ 990 $ 637 $ 822 Activity in the period: Provision for doubtful accounts 1,185 691 412 Account (chargeoffs) recoveries, net (842) (338) (597) At end of period $ 1,333 $ 990 $ 637 Inventories Inventories consist primarily of compressor package parts and supplies and work in process and are stated at the lower of cost or net realizable value. For parts and supplies, cost is determined using the weighted average cost method.The cost of work in progress is determined using the specific identification method. Property, Plant, and Equipment Property, plant, and equipment are stated at cost. Expenditures that increase the useful lives of assets are capitalized. The cost of repairs and maintenance is charged to cost of revenues as incurred. Compressors include compressor packages currently placed in service and available for service. Depreciation is computed using the straight-line method based on the following estimated useful lives: Buildings 15 – 30 years Compressors 12 – 20 years Other equipment 2 – 8 years Vehicles 3 – 5 years Information systems 7 years Leasehold improvements are depreciated over the shorter of the remaining term of the associated building lease or their useful lives. Depreciation expense for the years ended December 31, 2020, 2019, and 2018 was $76.6 million, $72.3 million, and $66.5 million, respectively. Construction in progress as of December 31, 2020 and 2019 consisted primarily of new compressor packages under fabrication and capital expenditures that sustain the capacity of our existing fleet. Intangible Assets Trademarks/trade names, customer relationships, and other intangible assets are amortized on a straight-line basis over their estimated useful lives, ranging from 2 to 15 years. Amortization expense related to intangible assets was $3.0 million for each of the years ended December 31, 2020, 2019, and 2018, and is included in depreciation and amortization. The estimated future annual amortization expense of trademarks/trade names, customer relationships, and other intangible assets is $2.9 million each year for 2021 to 2025. Our intangible assets are tested for recoverability whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. In such an event, we will determine the fair value of the asset using an undiscounted cash flow analysis of the asset at the lowest level for which identifiable cash flows exist. If an impairment has occurred, we will recognize a loss for the difference between the carrying value and the estimated fair value of the intangible asset. Impairments and Other Charges Impairments of long-lived assets, including identified intangible assets, are determined periodically, when indicators of impairment are present. If such indicators are present, the determination of the amount of impairment is based on our judgments as to the future undiscounted operating cash flows to be generated from these assets throughout their remaining estimated useful lives. If these undiscounted cash flows are less than the carrying amount of the related asset, an impairment is recognized for the excess of the carrying value over its fair value. Fair value of intangible assets is generally determined using the discounted present value of future cash flows using discount rates commensurate with the risks inherent with the specific assets. Assets held for disposal are recorded at the lower of carrying value or estimated fair value less estimated selling costs. During 2020, the COVID-19 pandemic and decline in oil and gas prices had a significant impact on our customers and industry, resulting in a decrease in demand in certain of our service lines. We started to see our customers decrease their capital budgets and adjust their operations accordingly, which led to a decline in orders for new compression equipment to be fabricated and sold to third parties. We concluded that these events were indicators of impairment for all our asset groups. We recorded impairments and other charges of approximately $15.4 million associated with non-core used compressor equipment, certain classes of our compression fleet that we re under utilized due to market preferences , and field inventory for compression and related services. Fair value used to determine impairments was estimated based on a market approach. During 2019, we recorded impairments of $2.3 million on certain units of our GasJack (R) fleet, reflecting our decision to dispose of these units upon management’s determination that refurbishing this equipment was not economic given limited current and forecasted demand for such equipment. There were 441 GasJack (R) units impaired, representing 20,286 of total horsepower. A recoverability analysis was performed on the remaining low-horsepower fleet and we concluded that the remaining fleet was recoverable from estimated future cash flows. In addition, a certain compressor package was written off due to being destroyed by fire, resulting in an additional charge of $0.8 million. During 2018, we recorded no impairments of long-lived assets. Accrued Liabilities Accrued liabilities are detailed as follows: December 31, 2020 2019 (In Thousands) Accrued interest $ 13,644 $ 14,666 Operating lease liabilities, current portion 8,099 6,706 Accrued taxes 5,282 9,428 Compensation and employee benefits 2,822 5,746 Accrued capital expenditures 1,379 2,647 Other accrued liabilities 4,575 2,132 Total accrued liabilities and other $ 35,801 $ 41,325 Revenue Recognition Performance Obligations. Revenue is recognized when performance obligations under the terms of a contract with our customer are satisfied. Revenue is generally recognized when we transfer control of our products or services to our customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or providing services to our customers. We receive cash equal to the invoice price for most product sales and services and payment terms typically range from 30 to 60 days from the date we invoice our customer. With the exception of the initial terms of our compression services contracts of our medium- and high-horsepower compressor packages, our customer contracts are generally for terms of one year or less. Since the period between when we deliver products or services and when the customer pays for products or services is not to exceed one year, we have elected not to calculate or disclose a financing component for our customer contracts. Depending on the terms of the arrangement, we may also defer the recognition of revenue for a portion of the consideration received because we have to satisfy a future performance obligation. For example, consideration received from customers during the fabrication of new compressor packages is typically deferred until control of the compressor package is transferred to our customer. For revenue associated with mobilization of service equipment as part of a service contract arrangement, such revenue, if significant, is deferred and amortized over the estimated service period. Compression and related services. For compression services revenues recognized over time, our customer contracts typically provide agreed upon monthly service rates and we recognize service revenue based upon the number of days that services have been performed. The majority of our compression services are provided pursuant to contract terms ranging from one month to twenty-four months. Monthly agreements are generally cancellable with 30 days written notice by the customer. Sales taxes, value added taxes, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. We recognize the cost for freight and shipping costs when control over our products (i.e. delivery) has transferred to the customer as part of cost of product sales. Use of Estimates. Our revenues do not include material amounts of variable consideration, as our revenues typically do not require significant estimates or judgments. The transaction price on a majority of our arrangements are fixed and product returns are immaterial. Additionally, our arrangements typically do not include multiple performance obligations that require estimates of the stand-alone purchase price for each performance obligation. Revenue on certain aftermarket service arrangements that include time as a component of the transaction price is not recognized until the performance obligation is complete. Contract Assets and Liabilities. We consider contract assets to be trade accounts receivable when we have an unconditional right to consideration and only the passage of time is required before payment is due. In certain instances, particularly those requiring customer specific documentation prior to invoicing, our invoicing of the customer is delayed until certain documentation requirements are met. In those cases, we recognize a contract asset rather than a billed trade accounts receivable until we are able to invoice the customer. Contract assets, along with billed trade accounts receivable, are included in trade accounts receivable in our consolidated balance sheets. We classify contract liabilities as unearned income in our consolidated balance sheets. Such unearned income typically results from advance payments received on orders for new compressor equipment prior to the time such equipment is completed and transferred to the customer in accordance with the customer contract. New equipment sales orders generally take less than twelve months to build and deliver. Equity-Based Compensation We have an equity incentive compensation plan which provides for the granting of phantom units and performance phantom units to the executive officers, key employees, non-executive officers, and directors of our general partner. Total equity-based compensation expense for the years ended December 31, 2020, 2019, and 2018, was $1.4 million, $1.1 million, and $0.6 million, respectively. For further discussion of equity-based compensation, see Note 11 - “Equity-Based Compensation.” Income Taxes Our operations are not subject to U.S. federal income tax other than the operations that are conducted through taxable subsidiaries. We incur state and local income taxes in certain areas of the U.S. in which we conduct business. We incur income taxes and are subject to withholding requirements related to certain of our operations in Latin America, Canada, and other foreign countries in which we operate. Furthermore, we also incur Texas Margin Tax, which, in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 740, is classified as an income tax for reporting purposes. A portion of the carrying value of certain deferred tax assets is subject to a valuation allowance. See Note 13 - “Income Taxes” for further discussion. In January 2018, the FASB released guidance on the accounting for tax on the global intangible low-taxed income (“GILTI”) provisions of the Tax Reform Act. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The guidance indicates that either accounting for deferred taxes related to GILTI inclusions or to treat any taxes on GILTI inclusions as period costs are both acceptable methods subject to an accounting policy election. As of December 31, 2018, we elected to account for GILTI as a period cost in the year the tax is incurred. Accumulated Other Comprehensive Income (Loss) Certain of our international operations maintain their accounting records in the local currencies that are their functional currencies. For these operations, the functional currency financial statements are converted to U.S. dollar equivalents, with the effect of the foreign currency translation adjustment reflected as a component of accumulated other comprehensive income (loss). Accumulated other comprehensive income (loss) is included in partners’ capital in the accompanying audited consolidated balance sheets and consists of the cumulative currency translation adjustments associated with such international operations. Activity within our accumulated other comprehensive income (loss) is not subject to reclassifications to net income. Allocation of Net Income Our net income (loss) is allocated to partners’ capital accounts in accordance with the provisions of the Partnership Agreement. Fair Value Measurements We utilize fair value measurements to account for certain items and account balances within our consolidated financial statements. Fair value measurements were utilized in the determination of the carrying value of our Series A Preferred Units (a Level 3 fair value measurement). We also utilize fair value measurements on a recurring basis in the accounting for our foreign currency forward purchase and sale derivative contracts. For these fair value measurements, we utilize the quoted value (a Level 2 fair value measurement). Refer to Note 12 - “Fair Value Measurements” for further discussion. Fair value measurements are also utilized on a nonrecurring basis, such as in the allocation of purchase consideration for acquisition transactions to the assets and liabilities acquired, including intangible assets (a Level 3 fair value measurement) and for the impairment of long-lived assets (a Level 3 fair value measurement). Distributions On January 20, 2020, April 20, 2020, July 20, 2020 and October 19, 2020, our General Partner declared a cash distribution attributable to the respective quarter end of $0.01 per common unit. These distributions each equate to a distribution of $0.04 per outstanding common unit on an annualized basis. These distributions were paid on February 14, 2020, May 15, 2020, August 14, 2020 and November 13, 2020, respectively, to the holders of common units of record as of the close of business on February 1, 2020, May 1, 2020, August 1, 2020 and November 1, 2020, respectively. Series A Preferred Units The fair value of the Series A Preferred Units were classified as a long-term liability on our consolidated balance sheets in accordance with ASC 480 “Distinguishing Liabilities and Equity” with changes in the fair value resulting in credits or charges to earnings in the accompanying consolidated statements of operations. Unless otherwise redeemed for cash, a ratable portion of the Preferred Units were converted into common units on the eighth day of each month over a period of thirty months that began in March 2017. In January 2019, we began redeeming Preferred Units for cash, resulting in 2,660,569 Preferred Units being redeemed during the year ended December 31, 2019 for $31.9 million, which includes approximately $1.5 million of redemption premium that was paid and charged to other (income) expense, net in the accompanying consolidated statements of operation. The last redemption of all remaining Preferred Units occurred on August 8, 2019. New Accounting Pronouncements Standards adopted In August 2018, the FASB issued Accounting Standards Update (“ASU”) 2018-15, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” ASU 2018-15 clarifies the accounting for implementation costs in cloud computing arrangements. On January 1, 2020, we adopted ASU 2018-15. The adoption of this standard did not have a material impact on our consolidated financial statements. Standards not yet adopted In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the more timely recognition of losses on financial instruments not accounted for at fair value through net income. The provisions require credit impairments to be measured over the contractual life of an asset and developed with consideration for past events, current conditions, and forecasts of future economic information. Credit impairments will be accounted for as an allowance for credit losses deducted from the amortized cost basis at each reporting date. Updates at each reporting date after initial adoption will be recorded through selling, general, and administrative expense. ASU 2016-13 is effective for us the first quarter of fiscal 2023. We continue to assess the potential effects of these changes to our consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” ASU 2019-12 simplifies the accounting for income taxes by eliminating certain exceptions related to intraperiod tax allocation, interim period income tax calculation methodology, and the recognition of deferred tax liabilities for outside basis differences. It also simplifies certain aspects of accounting for franchise taxes and clarifies the accounting for transactions that results in a step-up in the tax basis of goodwill. ASU 2019-12 is effective for us the first quarter of fiscal 2021. We continue to assess the potential effects of these changes to our consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848)”, which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) or by another reference rate expected to be discontinued. The amendments were effective for all entities as of March 12, 2020 through December 31, 2022. Entities may elect to apply the amendments for contract modifications as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020. As of December 31, 2020, we have not modified our credit agreements to remove references to LIBOR. We are currently evaluating the impact of the provisions of ASU 2020-04 on our consolidated financial statements.

Leases [Abstract]
Leases	LEASES We have operating leases for some of our office space, warehouse space, operating locations, and machinery and equipment. Our leases have remaining lease terms ranging from 1 to 10 years. Some of our leases have options to extend for various periods, while some have termination options with prior notice of generally 30 days or six months. Our leases generally require us to pay all maintenance and insurance costs. During the fourth quarter of 2019, we entered into a lease agreement commitment for 14 compressor packages. The leases have an initial term of seven years and commenced upon the completion of the fabrication of the compressor packages. During 2020, we took delivery of all 14 of the compressor packages. We have no other leases that have not yet commenced that create significant rights and obligations. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. In November 2019, we entered into a sale and leaseback transaction with a third-party lessor whereby we received $9.8 million of proceeds from the sale of compression equipment in service and entered into an associated lease of the same equipment with an initial lease term of seven years. Lease costs are included in either cost of revenues or selling, general, and administrative expense depending on the use of the underlying asset. Total lease expense (inclusive of lease expense for leases not included on our consolidated balance sheet based on our accounting policy election to exclude leases with a term of 12 months or less), was $13.5 million for the year ended December 31, 2020, of which, $3.2 million related to short-term leases. Total lease expense was $8.2 million ,of which, $2.8 million related to short-term leases, for the year ended December 31, 2019.

Credit Facility On June 11, 2020, the Partnership amended the Loan and Security Agreement dated June 29, 2018 (as amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “Credit Agreement”). The Credit Agreement provides for maximum revolving credit commitments of $35.0 million and includes a $5.0 million reserve, which results in reduced borrowing availability. The Credit Agreement includes a $25.0 million sublimit for letters of credit. As of December 31, 2020, and subject to compliance with the covenants, borrowing base, and other provisions of the agreements that may limit borrowings under the Credit Agreement, we had availability of $14.2 million. The maturity date of the Credit Agreement is June 29, 2023. As of December 31, 2020, we had no outstanding balance and had $3.5 million in letters of credit against our Credit Agreement. Because there was no outstanding balance on our variable rate revolving credit facility, associated deferred financing costs of $0.6 million were classified as other long-term assets on the accompanying consolidated balance sheet.

Related Party Transactions	Dec. 31, 2020
Related Party Transactions [Abstract]
Related Party Transactions	RELATED PARTY TRANSACTIONS Omnibus Agreement On June 20, 2014, the Partnership, CSI Compressco GP Inc. (the “General Partner”), and TETRA Technologies, Inc. (“TETRA”) entered into a First Amendment to Omnibus Agreement (the “First Amendment”). The First Amendment amended the Omnibus Agreement previously entered into on June 20, 2011 (as amended, the “Omnibus Agreement”) to extend the term thereof. The Omnibus Agreement terminated upon the closing of the GP Sale (as defined below). Under the terms of the Omnibus Agreement, our General Partner provides all personnel and services reasonably necessary to manage our operations and conduct our business (other than in Mexico, Canada, and Argentina), and certain of TETRA’s Latin American-based subsidiaries provide personnel and services necessary for the conduct of certain of our Latin American-based businesses. In addition, under the Omnibus Agreement, TETRA provides certain corporate and general and administrative services as requested by our General Partner, including, without limitation, legal, accounting and financial reporting, treasury, insurance administration, claims processing and risk management, health, safety and environmental, information technology, human resources, credit, payroll, internal audit, and tax services. Pursuant to the Omnibus Agreement, we reimburse our General Partner and TETRA for services they provide to us. For the years ended December 31, 2020, 2019, and 2018, we were charged by TETRA $32.6 million , $36.3.million, and $34.8 million, respectively, for expenses incurred on our behalf as described below. Amounts charged under the Omnibus Agreement and outstanding as of December 31, 2020 and 2019 are included in amounts payable to affiliates in the accompanying consolidated balance sheets. Under the terms of the Omnibus Agreement, we or TETRA could, but neither was under any obligation to, perform for the other such production enhancement or other oilfield services on a subcontract basis as were needed or desired by the other, for such periods of time and in such amounts as may be mutually agreed upon by TETRA and our General Partner. In addition, we or TETRA could, but were under no obligation to, sell, lease or exchange on a like-kind basis to the other such production enhancement or other oilfield services equipment as was needed or desired to meet either of our production enhancement or other oilfield services obligations, in such amounts, upon such conditions and for such periods of time, if applicable, as may have been mutually agreed upon by TETRA and our General Partner. Any such services, sales, leases, or like-kind exchanges were required to be performed on terms that were (i) approved by the conflicts committee of our General Partner’s board of directors, (ii) no less favorable to us than those generally being provided to or available from non-affiliated third parties, as determined by our General Partner, or (iii) fair and reasonable to us, taking into account the totality of the relationships between TETRA and us (including other transactions that may be particularly favorable or advantageous to us), as determined by our General Partner. Unless otherwise approved by the conflicts committee of our General Partner’s board of directors, TETRA could purchase from us previously fabricated equipment for a price that was not less than the sum of the net book value of such equipment plus a fixed margin percentage thereof. This description is not a complete discussion of this agreement and is qualified in its entirety by reference to the full text of the complete agreement, which is filed, along with other agreements, as exhibits to our filings with the SEC. In addition to the Omnibus Agreement, we have entered into other agreements with TETRA in the course of our operations. TETRA and General Partner Ownership TETRA’s ownership interest in us as of both December 31, 2020 and 2019 was approximately 35%, with the common units held by the public representing an approximate 65% interest in us. As of December 31, 2020, TETRA’s ownership was through various wholly owned subsidiaries and consisted of approximately 34.2% of the limited partner interests plus the approximate 1.4% general partner interest, through which it held incentive distribution rights. As a result of its ownership of common units and its general partner interest in us, TETRA received distributions of $0.7 million, $0.7 million, and $12.1 million during the years ended December 31, 2020, 2019, and 2018, respectively. See Note 18 - “Subsequent Events” for further discussion. Indemnification Agreement Each of our directors and officers entered into an indemnification agreement with regard to their services as a director or officer, in order to enhance the indemnification rights provided under Delaware law and our Partnership Agreement. The individual indemnification agreements provide each such director or officer with the right to receive his or her costs of defense if he or she is made a party or witness to any proceeding other than a proceeding brought by or in the right of us, provided that such director or officer has not acted in bad faith or engaged in fraud with respect to the action that gave rise to his or her participation in the proceeding. Other Sources of Financing In February 2019, we entered into a transaction with TETRA whereby TETRA agreed to fund the construction of and purchase from us up to $15.0 million of new compressor services equipment and to subsequently lease the equipment back to us in exchange for a monthly rental fee. As of November 30, 2020, pursuant to this arrangement, $14.8 million had been funded by TETRA for the construction of new compressor services equipment and all compression units were completed and deployed under this agreement. For accounting purposes, the inclusion of a repurchase option that allowed us to repurchase the equipment at a fixed price during certain periods of the agreement caused the transaction to be accounted for as a financing transaction, as opposed to a sale-leaseback, resulting in the funded amount being recorded as a financing obligation. Accordingly, the compressor services equipment is included in property, plant, and equipment and corresponding financing obligations are included in amounts payable to affiliates and long-term affiliate payable in our consolidated balance sheet as of December 31, 2019. In December 2020, TETRA sold these compressors and assigned the corresponding leases to Spartan Energy Partners LP (“Spartan”). In January 2021, TETRA sold the General Partner, IDRs and a majority of its common units in the Partnership to Spartan; see Note 18 - “Subsequent Events”. As of December 31, 2020, the financing obligation owed to Spartan was $14.7 million and is included in accrued liabilities and other and other long-term liabilities in our consolidated balance sheet as of December 31, 2020. Imputed interest expense recognized for the year ended December 31, 2020 was $3.4 million. The following table summarizes future financing obligation payments owed to Spartan by year as of December 31, 2020: Year Financing Obligation Payments (In Thousands) 2021 $ 3,015 2022 3,015 2023 3,015 2024 2,312 2025 — Total financing obligation payments $ 11,357

Discontinued Operations and Disposal Groups [Abstract]
Sale of Assets	SALE OF ASSETS In April 2020, we entered into a purchase and sale agreement for the sale of our Midland manufacturing facility. The Midland facility was used to design, fabricate and assemble new standard and customized compressor packages for our new unit sales business. On July 2, 2020, we completed the previously announced sale of our Midland manufacturing facility for a total sale price of $17.0 million. The sale of the Midland facility resulted in a gain of $0.3 million during the year ended December 31, 2020. Additionally, during the year ended December 31, 2020, we sold the remaining inventory and equipment related to the fabrication of new compressors for a gain of $0.5 million. These gains are reflected in income (loss) from discontinued operations, net of taxes in our statement of operations. Additionally, during the year ended December 31, 2020, we recorded an impairment of $3.1 million to reduce the Midland facility to its approximate fair market value based on a market approach and expected net proceeds. We also recorded an impairment of $2.3 million to reduce the carrying value of the new unit sales inventory to its approximate fair market value based on a market approach during the year ended December 31, 2020. These impairment charges are reflected in income (loss) from discontinued operations, net of taxes in our statement of operations. During the year ended December 31, 2020, we completed the sale of 58 low-horsepower units to one of our customers for $2.6 million and recorded an impairment of $3.7 million to reduce these assets to their approximate fair market value based on a market approach and expected net proceeds. The impairment charges are reflected in impairment and other charges in our statement of operations.

Discontinued Operations	DISCONTINUED OPERATIONSAs discussed in Note 8 - “Sale of Assets”, we completed the previously announced sale of our Midland manufacturing facility on July 2, 2020. The Midland facility was used to design, fabricate and assemble new standard and customized compressor packages for our new unit sales business. In connection with the Midland manufacturing facility sale, we entered into an agreement with the buyer to continue to operate a portion of the facility, which allowed us to close out the remaining backlog for the new unit sale business and to continue to operate our aftermarket services business at that location for an interim period. Following completion of the last unit in October 2020, we are no longer fabricating new compressor packages for sales to third parties or for our own service fleet. The operations associated with the new unit sales business was previously reported in equipment sales revenues and are now reflected as discontinued operations in our financial statements for all periods presented. Used equipment sales revenue continues to be included in equipment sales revenue. A summary of financial information related to our discontinued operations for the new unit sales business is as follows: Reconciliation of the Line Items Constituting Pretax Loss from Discontinued Operations to the After-Tax Income (Loss) from Discontinued Operations (in thousands) Year Ended December 31, 2020 2019 2018 Revenue $ 36,815 $ 136,488 $ 124,643 Cost of revenues 38,503 122,315 112,894 Depreciation, amortization, and accretion 526 1,034 1,017 Impairments of long-lived assets 5,474 — — General and administrative expense 3,904 6,471 5,344 Other (income) expense, net (773) (25) (1) Total pretax income (loss) from discontinued operations (10,819) 6,693 5,389 Income tax provision 67 406 250 Total income (loss) from discontinued operations $ (10,886) $ 6,287 $ 5,139 Reconciliation of Major Classes of Assets and Liabilities of the Discontinued Operations to Amounts Presented Separately in the Statement of Financial Position (in thousands) December 31, 2020 December 31, 2019 Carrying amounts of major classes of assets included as part of discontinued operations Trade receivables — 3,925 Inventories 32 19,521 Other Current Assets 7 111 Current assets of discontinued operations $ 39 $ 23,557 Property, plant, and equipment — 38,029 Other assets — — Long-term assets of discontinued operations — 38,029 Total assets of discontinued operations $ 39 $ 61,586 Carrying amounts of major classes of liabilities included as part of discontinued operations Trade payables $ — $ 26,496 Accrued liabilities 345 10,478 Current liabilities of discontinued operations $ 345 $ 36,974 Long-term liabilities of discontinued operations — — Total liabilities of discontinued operations $ 345 $ 36,974

Equity-Based Compensation	Dec. 31, 2019
Share-based Payment Arrangement [Abstract]
Equity-Based Compensation	EQUITY-BASED COMPENSATION 2011 Long Term Incentive Plan We have granted phantom unit and performance phantom unit awards to certain employees, officers, and directors of our General Partner pursuant to the CSI Compressco LP Second Amended and Restated 2011 Long Term Incentive Plan. Awards of phantom units generally vest over a three year period. Awards of performance phantom units cliff vest at the end of a performance period and are settled based on achievement of related performance measures over the performance period. Each of the phantom unit and performance phantom unit awards includes distribution equivalent rights that enable the recipient to receive additional units equal in value to the accumulated cash distributions made on the units subject to the award from the date of grant. Accumulated distributions associated with each underlying unit are payable upon settlement of the related phantom unit award (and are forfeited if the related award is forfeited). Phantom units are notional units that entitle the grantee to receive a common unit upon the vesting of the award. During the year ended December 31, 2020, we granted to certain officers and employees an aggregate of 1,329,830 phantom unit and performance phantom unit awards, having an average market value (equal to the closing price of the common units on the dates of grant) of $2.08 per unit, or an aggregate market value of $2.8 million. During the year ended December 31, 2019, we granted to certain officers and employees 1,001,071 phantom unit and performance phantom unit awards, having an average market value (equal to the closing price of the common units on the dates of grant) of $2.71 per unit, or an aggregate market value of $2.7 million. During the year ended December 31, 2018, we granted to certain officers and employees 330,395 phantom unit and performance unit awards, having an average market value (equal to the closing price of the common units on the dates of grant) of $7.33 per unit, or an aggregate market value of $2.4 million. The fair value of awards vesting during 2020 , 2019, and 2018 was approximately $1.1 million, $1.2 million, and $1.5 million, respectively. The fair value of awards is amortized straight-line over the vesting period. Adjustments to the amortized expense related to performance phantom units may be recognized prior to vesting depending on the expected achievement of the performance target. The following is a summary of unit activity for the year ended December 31, 2020: Units Weighted Average (In Thousands) Nonvested units outstanding at December 31, 2019 817 $ 3.59 Units granted (1) 1,329 2.08 Cancelled/forfeited (290) 3.33 Exercised/released (302) 3.76 Nonvested units outstanding at December 31, 2020 (2) 1,554 $ 2.31 (1) This number excludes 206,037 performance-based phantom units, which represents the maximum number of common units that would be issued if the maximum level of performance under the awards is achieved. (2) This number excludes an additional 128,705 performance-based phantom units, which, when combined with the 206,037 granted, (net of 2020 forfeitures), represents the maximum number of common units that would be issued if the maximum level of performance under the awards is achieved. The number of units actually issued under the awards may range from zero to 669,484 . Total estimated unrecognized equity-based compensation expense from unvested units as of December 31, 2020 , was approximately $2.2 million and is expected to be recognized over a weighted average period of approximately 1.9 years. The amount recognized in 2020, 2019, and 2018 was approximately $1.4 million, $1.1 million, and $0.6 million, respectively, and is included in selling, general, and administrative expense in our consolidated statements of operations.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Fair Value Disclosures	FAIR VALUE MEASUREMENTSFair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date” within an entity’s principal market, if any. The principal market is the market in which the reporting entity would sell the asset or transfer the liability with the greatest volume and level of activity, regardless of whether it is the market in which the entity will ultimately transact for a particular asset or liability or if a different market is potentially more advantageous. Accordingly, this exit price concept may result in a fair value that may differ from the transaction price or market price of the asset or liability. Under U.S. GAAP, the fair value hierarchy prioritizes inputs to valuation techniques used to measure fair value. Fair value measurements should maximize the use of observable inputs and minimize the use of unobservable inputs, where possible. Observable inputs are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs may be needed to measure fair value in situations where there is little or no market activity for the asset or liability at the measurement date and are developed based on the best information available in the circumstances, which could include the reporting entity’s own judgments about the assumptions market participants would utilize in pricing the asset or liability. Financial Instruments Series A Preferred Units All remaining outstanding Preferred Units were redeemed for cash on August 8, 2019. Prior to that, the Preferred Units were valued using a lattice modeling technique that, among a number of lattice structures, included significant unobservable items (a level 3 fair value measurement). These unobservable items included (i) the volatility of the trading price of our common units compared to a volatility analysis of equity prices of comparable peer companies, (ii) a yield analysis that utilized market information related to the debt yields of comparable peer companies, and (iii) a future conversion price analysis. Increases (or decreases) in the fair value of our Preferred Units increased (decreased) the associated liability and resulted in adjustments to earnings for the associated valuation losses (gains). Derivative Contracts We have currency exchange rate risk exposure related to transactions denominated in a foreign currency as well as to investments in certain of our international operations. We enter into 30-day foreign currency forward derivative contracts as part of a program designed to mitigate the currency exchange rate risk exposure on selected transactions of certain foreign subsidiaries. As of December 31, 2020 and 2019, we had the following foreign currency derivative contracts outstanding relating to a portion of our foreign operations: December 31, 2020 US Dollar Notional Amount Traded Exchange Rate Settlement Date (In Thousands) Forward sale Mexican peso $ 6,002 $ 19.11 1/4/2021 December 31, 2019 US Dollar Notional Amount Traded Exchange Rate Settlement Date (In Thousands) Forward sale Mexican peso $ 8,656 $ 19.06 1/17/2020 Under a program designed to mitigate the currency exchange rate risk exposure on selected transactions of certain foreign subsidiaries, we may enter into similar derivative contracts from time to time. Although contracts pursuant to this program will serve as economic hedges of the cash flow of our currency exchange risk exposure, they will not be formally designated as hedge contracts or qualify for hedge accounting treatment. Accordingly, any change in the fair value of these derivative instruments during a period will be included in the determination of earnings for that period. The fair values of our foreign currency derivative contracts are based on quoted market values (a Level 2 fair value measurement). None of the foreign currency derivative contracts contains credit risk related contingent features that would require us to post assets or collateral for contracts that are classified as liabilities. During the year ended December 31, 2020, 2019, and 2018, we recognized approximately $(0.2) million, $0.8 million, and $0.05 million of net (gains) and losses, respectively, associated with our foreign currency derivative program, and such amount is included in other (income) expense, net in the accompanying consolidated statement of operations. Fair Value of Debt The fair value of our debt has been estimated in accordance with the accounting standard regarding fair value. The fair value of our fixed rate long-term debt is estimated based on recent trades for these notes.

During the year ended December 31, 2019, we recorded impairments primarily related to $2.3 million on certain units of our GasJack (R) fleet, reflecting our decision to dispose of these units upon management's determination that refurbishing this equipment was not economic given limited current and forecasted demand for such equipment, as well as a $0.8 million impairment for a compressor package damaged by fire. During the year ended December 31, 2018, we recorded no impairments of long-lived assets. The fair values used in the 2020 impairment calculations were estimated based on discounted estimated future cash flows, including projected future cash flows and/or estimated replacement costs, or a fair value in-exchange assumption, which are based on significant unobservable inputs (Level 3) in accordance with the fair value hierarchy.

Income Taxes	Dec. 31, 2020
Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES As a partnership, we are generally not subject to income taxes at the entity level because our income is included in the tax returns of our partners. We are treated as a partnership for federal tax purposes with each partner being separately taxed on its share of our taxable income. However, a portion of our business is conducted through taxable U.S. corporate subsidiaries. Accordingly, a U.S. federal and state income tax provision has been reflected in the accompanying statements of operations. We have a tax sharing agreement with TETRA with respect to the Texas franchise tax liability. The resulting state tax expense is included in the provision for income taxes. Certain of our operations are located outside of the U.S. and we, through our foreign subsidiaries, are responsible for income taxes in these countries. The income tax provision (benefit) attributable to our operations for the years ended December 31, 2020, 2019, and 2018 consists of the following: Year Ended December 31, 2020 2019 2018 (In Thousands) Current Federal $ — $ — $ — State 663 1,049 855 Foreign 2,186 1,769 1,688 2,849 2,818 2,543 Deferred Federal — — 72 State 15 (11) (4) Foreign 280 140 (246) 295 129 (178) Total tax provision $ 3,144 $ 2,947 $ 2,365 A reconciliation of the provision for income taxes computed by applying the federal statutory rate to income (loss) before income taxes and the reported income taxes is as follows: Year Ended December 31, 2020 2019 2018 (In Thousands) Income (loss) tax provision computed at statutory federal income tax rates $ (12,560) $ (5,106) $ (8,348) Partnership (earnings) losses 12,560 5,106 8,348 Corporate subsidiary earnings (loss) subject to federal tax (1,800) (998) (387) Valuation allowances 2,133 1,300 (645) Income tax expense attributable to foreign earnings 1,934 1,047 1,992 State income taxes (net of federal benefit) 764 1,504 1,328 Other 113 94 77 Total tax provision $ 3,144 $ 2,947 $ 2,365 Income (loss) before income tax provision includes the following components: Year Ended December 31, 2020 2019 2018 (In Thousands) United States $ (67,992) $ (33,241) $ (42,692) International 8,182 8,928 2,940 Total $ (59,810) $ (24,313) $ (39,752) We file U.S. federal, state, and foreign income tax returns on behalf of all of our consolidated subsidiaries. With few exceptions, we are not subject to U.S. federal, state, local, or non-U.S. income tax examinations by tax authorities for years prior to 2013. We file tax returns in the U.S. and in various state, local and non-U.S. jurisdictions. The following table summarizes the earliest tax years that remain subject to examination by taxing authorities in any major jurisdiction in which we operate: Jurisdiction Earliest Open Tax Period United States – Federal 2014 United States – State and Local 2014 Non-U.S. jurisdictions 2013 We use the liability method for reporting income taxes, under which current and deferred tax assets and liabilities are recorded in accordance with enacted tax laws and rates. Under this method, at the end of each period, the amounts of deferred tax assets and liabilities are determined using the tax rate expected to be in effect when the taxes are actually paid or recovered. We establish a valuation allowance to reduce the deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized. While we consider taxable income in prior carryback years, future reversals of existing taxable temporary differences, future taxable income, and tax planning strategies in assessing the need for the valuation allowance, there can be no guarantee that we will be able to realize all of our deferred tax assets. Significant components of our deferred tax assets and liabilities are as follows: December 31, 2020 December 31, 2019 Deferred Tax Assets (In Thousands) Amortization for book in excess of tax expense 19,939 22,396 Accruals 3,542 3,318 Net operating losses 22,816 18,164 Other 3,302 2,729 Total deferred tax assets 49,599 46,607 Valuation allowance (41,830) (37,649) Net deferred tax assets $ 7,769 $ 8,958 December 31, 2020 December 31, 2019 Deferred Tax Liabilities (In Thousands) Accruals $ 1,938 $ 2,350 Depreciation for tax in excess of book expense 3,734 4,677 Right-of-use Asset 3,330 2,892 All other 235 226 Total deferred tax liability 9,237 10,145 Net deferred tax liability $ 1,468 $ 1,187 At December 31, 2020, we have federal, state, and foreign net operating loss carryforwards/carrybacks equal to approximately $19.8 million, $1.6 million, and $1.4 million, respectively. In those foreign jurisdictions and states in which net operating losses are subject to an expiration period, our loss carryforwards, if not utilized, will expire from 2021 to 2039. Utilization of the net operating loss and credit carryforwards may be subject to a significant annual limitation due to ownership changes that have occurred previously or could occur in the future provided by Section 382 of the Internal Revenue Code of 1986, as amended. The valuation allowance increased $4.2 million during the year ended December 31, 2020 primarily due to the increase in deferred tax assets as a result of losses generated by our U.S. corporate subsidiaries. The valuation allowance during the year ended December 31, 2019 remained constant. The valuation allowance decreased $1.7 million during the year ended December 31, 2018 primarily due to the reduction of the deferred tax assets as a result of income generated by our U.S. corporate subsidiaries. We believe that it is more likely than not we will not realize all the tax benefits of the deferred tax assets within the allowable carryforward period. Therefore, an appropriate valuation allowance has been provided. ASC 740, “Income Taxes” provides guidance on measurement and recognition in accounting for income tax uncertainties and provides related guidance on derecognition, classification, disclosure, interest, and penalties. As of December 31, 2020 and 2019, the Partnership had no material unrecognized tax benefits (as defined in ASC 740-10). We do not expect to incur interest charges or penalties related to our tax positions, but if such charges or penalties are incurred, our policy is to account for interest charges as interest expense and penalties as tax expense in the consolidated statements of operations.

Earnings Per Common and Subordinated Unit	Dec. 31, 2020
Earnings Per Share [Abstract]
Earnings Per Common and Subordinated Unit	EARNINGS PER COMMON UNIT The computations of earnings per common unit are based on the weighted average number of common units outstanding during the applicable full-year period. Basic earnings per common unit is determined by dividing net income (loss) allocated to the common units after deducting the amount allocated to our General Partner (including distributions to our General Partner on its incentive distribution rights) by the weighted average number of outstanding common units during the period. When computing earnings per common unit under the two-class method in periods when distributions are greater than earnings, the amount of the distributions is deducted from net income (loss) and the excess of distributions over earnings is allocated between the General Partner and common units based on how our partnership agreement allocates net losses. When earnings are greater than distributions, we determine cash distributions based on available cash and determine the actual incentive distributions allocable to our General Partner based on actual distributions. When computing earnings per common unit, the amount of the assumed incentive distribution rights, if any, is deducted from net income and allocated to our General Partner for the period to which the calculation relates. The remaining amount of net income, after deducting the assumed incentive distribution rights, is allocated between the General Partner and common units based on how our partnership agreement allocates net earnings. The following is the number of the weighted average basic and diluted common units outstanding: Year Ended December 31, 2020 2019 2018 Weighted average basic and diluted common units outstanding 47,301,804 47,006,543 41,552,804 Diluted earnings per unit are computed using the treasury stock method which considers the potential future issuance of limited partner common units. Unvested phantom units are not included in basic earnings per common unit, as they are not considered to be participating securities, but are included in the calculation of diluted earnings per common unit. As of December 31, 2020 there were no units excluded from the dilution calculation. As of December 31, 2019 and 2018 approximately 131,576, and 29,276 incremental units, respectively, were excluded from the calculation of diluted units because the impact was anti-dilutive. Following the issuance of the Preferred Units, diluted earnings per common unit was computed using the “if converted” method, whereby the amount of net income (loss) and the number of common units issuable are each adjusted as if the Preferred Units had been converted as of the date of issuance or as of the beginning of the period. The number of common units that may be issued upon future conversion of the Preferred Units was excluded from the calculation of diluted common units as the impact would be antidilutive due to the net loss recorded during the years ended December 31, 2019, and 2018. All remaining outstanding Preferred Units were redeemed for cash on August 8, 2019.

Segment Reporting [Abstract]
Segments	SEGMENTS ASC 280, “Segment Reporting”, defines the characteristics of an operating segment as (i) being engaged in business activity from which it may earn revenues and incur expenses, (ii) being reviewed by the company’s chief operating decision maker (“CODM”) to make decisions about resources to be allocated and to assess its performance, and (iii) having discrete financial information. Although management of our General Partner reviews our products and services to analyze the nature of our revenue, other financial information, such as certain costs and expenses, and net income are not captured or analyzed by these items. Therefore, discrete financial information is not available by product line and our CODM does not make resource allocation decisions or assess the performance of the business based on these items, but rather in the aggregate. Based on this, our General Partner believes that we operate in one business segment.

Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS The Partnership has evaluated subsequent events through the filing of this Annual Report on Form 10-K, and determined that there have been no events that have occurred that would require adjustments to our disclosures in the consolidated financial statements except for the transactions described below. On January 19, 2021, the board of directors of our General Partner declared a cash distribution attributable to the quarter ended December 31, 2020 of $0.01 per common unit. This distribution equates to a distribution of $0.04 per outstanding common unit on an annualized basis. This distribution was paid on February 12, 2021 , to the holders of common units of record as of the close of business January 29, 2021. On January 29, 2021, Spartan acquired from TETRA the Partnership’s General Partner, IDRs and 10.95 million common units in the Partnership (the “GP Sale”). The Partnership did not issue any common units or incur any debt as a result of the transaction. TETRA will continue to own 5.2 million common units of the Partnership. TETRA will also continue to provide back office support to the Partnership under a Transition Services Agreement for a period of time until the Partnership has completed a full separation from TETRA’s back-office support functions. Upon the closing of the GP Sale, the Omnibus Agreement terminated in accordance with its terms. Additionally, on January 29, 2021, the Partnership amended the Credit Agreement to temporarily increase the size of the reserve to $10.0 million and also requires that Spartan backstop all of our outstanding letters of credit. These temporary restrictions will expire on April 30, 2021 if there has not been a “Change of Control” under the Partnership’s secured senior notes indentures.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Dec. 31, 2020	Dec. 31, 2019
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Lessee, Leases [Policy Text Block]	Leases As a lessee, unless the lease meets the criteria of short-term and is excluded per our policy election described below, we initially recognize a lease liability and related right-of-use asset on the commencement date. The right-of-use asset represents our right to use an underlying asset and the lease liability represents our obligation to make lease payments to the lessor over the lease term. All of our long-term leases are operating leases and are included in operating lease right-of-use assets, accrued liabilities and other, and operating lease liabilities in our consolidated balance sheet as of December 31, 2020 and 2019. We determine whether a contract is or contains a lease at inception of the contract. Where we are a lessee in a contract that includes an option to extend or terminate the lease, we include the extension period or exclude the period covered by the termination option in our lease term in determining the right-of-use asset and lease liability, if it is reasonably certain that we would exercise the option. As an accounting policy election, we do not include short-term leases on our balance sheet. Short-term leases include leases with a term of 12 months or less, inclusive of renewal options we are reasonably certain to exercise. The lease payments for short-term leases are included as operating lease costs on a straight-line basis over the lease term in cost of revenues or selling, general, and administrative expense based on the use of the underlying asset. We recognize lease costs for variable lease payments not included in the determination of a lease liability in the period in which an obligation is incurred. As allowed by U.S. GAAP, we do not separate nonlease components from the associated lease component for our compression services contracts and instead account for those components as a single component based on the accounting treatment of the predominant component. In our evaluation of whether Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 842 “Leases” or ASC 606 “Revenue from Contracts with Customers” is applicable to the combined component based on the predominant component, we determined the services nonlease component is predominant, resulting in the ongoing recognition of our compression services contracts following ASC 606. Our operating leases are recognized at the present value of lease payments over the lease term. When the implicit discount rate is not readily determinable, we use our incremental borrowing rate to calculate the discount rate used to determine the present value of lease payments. Consistent with other long-lived assets or asset groups that are held and used, we test for impairment of our right-of-use assets when impairment indicators are present.
Consolidation policy	Our consolidated financial statements include the accounts of our wholly owned subsidiaries. All intercompany balances and transactions have been eliminated.
Use of estimates policy	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclose contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues, expenses, and impairments during the reporting period. Actual results could differ from those estimates, and such differences could be material.
Reclassifications policy	Reclassifications Certain previously reported financial information has been reclassified to conform to the current year’s presentation. For a discussion of the reclassification of the financial presentation of our new unit sales business as discontinued operations, see Note 9 - “Discontinued Operations.” Unless otherwise noted, amounts and disclosures throughout these Notes to Consolidated Financial Statements relate solely to continuing operations and exclude all discontinued operations.
Cash equivalents policy	Cash Equivalents We consider all highly liquid cash investments with maturities of three months or less when purchased to be cash equivalents.
Financial instruments policy	Financial Instruments Financial instruments that subject us to concentrations of credit risk consist principally of trade accounts receivable, which are primarily due from companies of varying size engaged in oil and gas activities in the United States, Canada, Mexico, and Argentina. Our policy is to review the financial condition of customers before extending credit and periodically update customer credit information. Payment terms are on a short-term basis. The risk of loss from the inability to collect trade receivables is heightened during prolonged periods of low oil and natural gas commodity prices. We have currency exchange rate risk exposure related to transactions denominated in a foreign currency as well as to investments in certain of our international operations. Our risk management activities include the use of foreign currency forward purchase and sale derivative contracts as part of a program designed to mitigate the currency exchange rate risk exposure on selected international operations. We have no balance outstanding under our variable rate revolving credit facility as of December 31, 2020 and face market risk exposure related to changes in applicable interest rates when balances are outstanding. Significant Customers During the years ended December 31, 2020, 2019 and 2018 , one individual customer accounted for 10% or more of our revenues. As of December 31, 2020 and 2019, no receivables from individual customers represented 10% or more of our consolidated trade accounts receivable net of allowance for doubtful accounts.
Foreign currencies policy	Foreign Currencies We have designated the Canadian dollar as the functional currency for our operations in Canada. We are exposed to fluctuations between the U.S. dollar and certain foreign currencies, including the Canadian dollar, the Mexican peso, and the Argentine peso, as a result of our international operations. Foreign currency exchange gains are included in other (income) expense, net, and totaled $0.5 million, $2.6 million, and $1.4 million during the years ended December 31, 2020, 2019, and 2018, respectively.
Allowances for doubtful accounts policy	Allowance for Doubtful Accounts The allowance for doubtful accounts is determined on a specific identification basis when we believe that the collection of specific amounts owed to us is not probable. Changes in the allowance are as follows: Year Ended December 31, 2020 2019 2018 (In Thousands) At beginning of period $ 990 $ 637 $ 822 Activity in the period: Provision for doubtful accounts 1,185 691 412 Account (chargeoffs) recoveries, net (842) (338) (597) At end of period $ 1,333 $ 990 $ 637
Inventories policy	Inventories Inventories consist primarily of compressor package parts and supplies and work in process and are stated at the lower of cost or net realizable value. For parts and supplies, cost is determined using the weighted average cost
Property, plant, and equipment policy		Property, Plant, and Equipment Property, plant, and equipment are stated at cost. Expenditures that increase the useful lives of assets are capitalized. The cost of repairs and maintenance is charged to cost of revenues as incurred. Compressors include compressor packages currently placed in service and available for service. Depreciation is computed using the straight-line method based on the following estimated useful lives: Buildings 15 – 30 years Compressors 12 – 20 years Other equipment 2 – 8 years Vehicles 3 – 5 years Information systems 7 years Leasehold improvements are depreciated over the shorter of the remaining term of the associated building lease or their useful lives. Depreciation expense for the years ended December 31, 2020, 2019, and 2018 was $76.6 million, $72.3 million, and $66.5 million, respectively. Construction in progress as of December 31, 2020 and 2019 consisted primarily of new compressor packages under fabrication and capital expenditures that sustain the capacity of our existing fleet.
Intangible assets other than goodwill policy	Intangible Assets Trademarks/trade names, customer relationships, and other intangible assets are amortized on a straight-line basis over their estimated useful lives, ranging from 2 to 15 years. Amortization expense related to intangible assets was $3.0 million for each of the years ended December 31, 2020, 2019, and 2018, and is included in depreciation and amortization. The estimated future annual amortization expense of trademarks/trade names, customer relationships, and other intangible assets is $2.9 million each year for 2021 to 2025.
Impairment of long-lived assets policy	Impairments and Other Charges Impairments of long-lived assets, including identified intangible assets, are determined periodically, when indicators of impairment are present. If such indicators are present, the determination of the amount of impairment is based on our judgments as to the future undiscounted operating cash flows to be generated from these assets throughout their remaining estimated useful lives. If these undiscounted cash flows are less than the carrying amount of the related asset, an impairment is recognized for the excess of the carrying value over its fair value. Fair value of intangible assets is generally determined using the discounted present value of future cash flows using discount rates commensurate with the risks inherent with the specific assets. Assets held for disposal are recorded at the lower of carrying value or estimated fair value less estimated selling costs. During 2020, the COVID-19 pandemic and decline in oil and gas prices had a significant impact on our customers and industry, resulting in a decrease in demand in certain of our service lines. We started to see our customers decrease their capital budgets and adjust their operations accordingly, which led to a decline in orders for new compression equipment to be fabricated and sold to third parties. We concluded that these events were indicators of impairment for all our asset groups. We recorded impairments and other charges of approximately $15.4 million associated with non-core used compressor equipment, certain classes of our compression fleet that we re under utilized due to market preferences , and field inventory for compression and related services. Fair value used to determine impairments was estimated based on a market approach. During 2019, we recorded impairments of $2.3 million on certain units of our GasJack (R) fleet, reflecting our decision to dispose of these units upon management’s determination that refurbishing this equipment was not economic given limited current and forecasted demand for such equipment. There were 441 GasJack (R) units impaired, representing 20,286 of total horsepower. A recoverability analysis was performed on the remaining low-horsepower fleet and we concluded that the remaining fleet was recoverable from estimated future cash flows. In addition, a certain compressor package was written off due to being destroyed by fire, resulting in an additional charge of $0.8 million. During 2018, we recorded no impairments of long-lived assets.
Revenue recognition policy	Revenue Recognition Performance Obligations. Revenue is recognized when performance obligations under the terms of a contract with our customer are satisfied. Revenue is generally recognized when we transfer control of our products or services to our customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or providing services to our customers. We receive cash equal to the invoice price for most product sales and services and payment terms typically range from 30 to 60 days from the date we invoice our customer. With the exception of the initial terms of our compression services contracts of our medium- and high-horsepower compressor packages, our customer contracts are generally for terms of one year or less. Since the period between when we deliver products or services and when the customer pays for products or services is not to exceed one year, we have elected not to calculate or disclose a financing component for our customer contracts. Depending on the terms of the arrangement, we may also defer the recognition of revenue for a portion of the consideration received because we have to satisfy a future performance obligation. For example, consideration received from customers during the fabrication of new compressor packages is typically deferred until control of the compressor package is transferred to our customer. For revenue associated with mobilization of service equipment as part of a service contract arrangement, such revenue, if significant, is deferred and amortized over the estimated service period. Compression and related services. For compression services revenues recognized over time, our customer contracts typically provide agreed upon monthly service rates and we recognize service revenue based upon the number of days that services have been performed. The majority of our compression services are provided pursuant to contract terms ranging from one month to twenty-four months. Monthly agreements are generally cancellable with 30 days written notice by the customer. Sales taxes, value added taxes, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. We recognize the cost for freight and shipping costs when control over our products (i.e. delivery) has transferred to the customer as part of cost of product sales. Use of Estimates. Our revenues do not include material amounts of variable consideration, as our revenues typically do not require significant estimates or judgments. The transaction price on a majority of our arrangements are fixed and product returns are immaterial. Additionally, our arrangements typically do not include multiple performance obligations that require estimates of the stand-alone purchase price for each performance obligation. Revenue on certain aftermarket service arrangements that include time as a component of the transaction price is not recognized until the performance obligation is complete. Contract Assets and Liabilities. We consider contract assets to be trade accounts receivable when we have an unconditional right to consideration and only the passage of time is required before payment is due. In certain instances, particularly those requiring customer specific documentation prior to invoicing, our invoicing of the customer is delayed until certain documentation requirements are met. In those cases, we recognize a contract asset rather than a billed trade accounts receivable until we are able to invoice the customer. Contract assets, along with billed trade accounts receivable, are included in trade accounts receivable in our consolidated balance sheets. We classify contract liabilities as unearned income in our consolidated balance sheets. Such unearned income typically results from advance payments received on orders for new compressor equipment prior to the time such equipment is completed and transferred to the customer in accordance with the customer contract. New equipment sales orders generally take less than twelve months to build and deliver.
Income tax policy	Income Taxes Our operations are not subject to U.S. federal income tax other than the operations that are conducted through taxable subsidiaries. We incur state and local income taxes in certain areas of the U.S. in which we conduct business. We incur income taxes and are subject to withholding requirements related to certain of our operations in Latin America, Canada, and other foreign countries in which we operate. Furthermore, we also incur Texas Margin Tax, which, in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 740, is classified as an income tax for reporting purposes. A portion of the carrying value of certain deferred tax assets is subject to a valuation allowance. See Note 13 - “Income Taxes” for further discussion. In January 2018, the FASB released guidance on the accounting for tax on the global intangible low-taxed income (“GILTI”) provisions of the Tax Reform Act. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The guidance indicates that either accounting for
Accumulated other comprehensive income policy	Accumulated Other Comprehensive Income (Loss) Certain of our international operations maintain their accounting records in the local currencies that are their functional currencies. For these operations, the functional currency financial statements are converted to U.S. dollar equivalents, with the effect of the foreign currency translation adjustment reflected as a component of accumulated other comprehensive income (loss). Accumulated other comprehensive income (loss) is included in partners’ capital in the accompanying audited consolidated balance sheets and consists of the cumulative currency translation adjustments associated with such international operations. Activity within our accumulated other comprehensive income (loss) is not subject to reclassifications to net income.
Allocation of net income policy	Allocation of Net Income Our net income (loss) is allocated to partners’ capital accounts in accordance with the provisions of the Partnership Agreement.
Fair value measurements policy	Fair Value Measurements We utilize fair value measurements to account for certain items and account balances within our consolidated financial statements. Fair value measurements were utilized in the determination of the carrying value of our Series A Preferred Units (a Level 3 fair value measurement). We also utilize fair value measurements on a recurring basis in the accounting for our foreign currency forward purchase and sale derivative contracts. For these fair value measurements, we utilize the quoted value (a Level 2 fair value measurement). Refer to Note 12 - “Fair Value Measurements” for further discussion. Fair value measurements are also utilized on a nonrecurring basis, such as in the allocation of purchase consideration for acquisition transactions to the assets and liabilities acquired, including intangible assets (a Level 3 fair value measurement) and for the impairment of long-lived assets (a Level 3 fair value measurement). Distributions On January 20, 2020, April 20, 2020, July 20, 2020 and October 19, 2020, our General Partner declared a cash distribution attributable to the respective quarter end of $0.01 per common unit. These distributions each equate to a distribution of $0.04 per outstanding common unit on an annualized basis. These distributions were paid on February 14, 2020, May 15, 2020, August 14, 2020 and November 13, 2020, respectively, to the holders of common units of record as of the close of business on February 1, 2020, May 1, 2020, August 1, 2020 and November 1, 2020, respectively. Series A Preferred Units The fair value of the Series A Preferred Units were classified as a long-term liability on our consolidated balance sheets in accordance with ASC 480 “Distinguishing Liabilities and Equity” with changes in the fair value resulting in credits or charges to earnings in the accompanying consolidated statements of operations. Unless otherwise redeemed for cash, a ratable portion of the Preferred Units were converted into common units on the eighth day of each month over a period of thirty months that began in March 2017. In January 2019, we began redeeming Preferred Units for cash, resulting in 2,660,569 Preferred Units being redeemed during the year ended December 31, 2019 for
Recently issued accounting pronouncements policy	New Accounting Pronouncements Standards adopted In August 2018, the FASB issued Accounting Standards Update (“ASU”) 2018-15, “Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” ASU 2018-15 clarifies the accounting for implementation costs in cloud computing arrangements. On January 1, 2020, we adopted ASU 2018-15. The adoption of this standard did not have a material impact on our consolidated financial statements. Standards not yet adopted In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the more timely recognition of losses on financial instruments not accounted for at fair value through net income. The provisions require credit impairments to be measured over the contractual life of an asset and developed with consideration for past events, current conditions, and forecasts of future economic information. Credit impairments will be accounted for as an allowance for credit losses deducted from the amortized cost basis at each reporting date. Updates at each reporting date after initial adoption will be recorded through selling, general, and administrative expense. ASU 2016-13 is effective for us the first quarter of fiscal 2023. We continue to assess the potential effects of these changes to our consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” ASU 2019-12 simplifies the accounting for income taxes by eliminating certain exceptions related to intraperiod tax allocation, interim period income tax calculation methodology, and the recognition of deferred tax liabilities for outside basis differences. It also simplifies certain aspects of accounting for franchise taxes and clarifies the accounting for transactions that results in a step-up in the tax basis of goodwill. ASU 2019-12 is effective for us the first quarter of fiscal 2021. We continue to assess the potential effects of these changes to our consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848)”, which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) or by another reference rate expected to be discontinued. The amendments were effective for all entities as of March 12, 2020 through December 31, 2022. Entities may elect to apply the amendments for contract modifications as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020. As of December 31, 2020, we have not modified our credit agreements to remove references to LIBOR. We are currently evaluating the impact of the provisions of ASU 2020-04 on our consolidated financial statements.
