Accounting Policies [Abstract]
Organization, Basis of Presentation, Business Description and Accounting Policies	ORGANIZATION, BASIS OF PRESENTATION, AND SIGNIFICANT ACCOUNTING POLICIES Organization 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 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 United States 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 2 – “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. Presentation Our unaudited consolidated financial statements include the accounts of our wholly owned subsidiaries. All intercompany balances and transactions have been eliminated. In the opinion of our management, our unaudited consolidated financial statements as of March 31, 2021, and for the three-month periods ended March 31, 2021 and 2020, include all normal recurring adjustments that are necessary to provide a fair statement of our results for these interim periods. Operating results for the three-month period ended March 31, 2021 are not necessarily indicative of results that may be expected for the twelve months ended December 31, 2021. The accompanying unaudited consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the U.S. Securities and Exchange Commission (“SEC”) and do not include all information and footnotes required by U.S. generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. These financial statements should be read in conjunction with the financial statements for the year ended December 31, 2020 and notes thereto included in our Annual Report on Form 10-K , which we filed with the SEC on March 4, 2021. Segments Our General Partner has concluded that we operate in one business segment. Significant Accounting Policies Our significant accounting policies are described in the notes to our consolidated financial statements for the year ended December 31, 2020 included in our Annual Report on Form 10-K . There have been no significant changes in our accounting policies or the application thereof during the three months ended March 31, 2021. 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 present our new unit sales business as discontinued operations. See Note 2 – “Discontinued Operations” for further information. In addition, certain previously reported financial information has been reclassified to conform to the current year’s presentation. Other than the discontinued operations presentation, the impact of reclassifications was not significant to the prior year's overall presentation. 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. Foreign Currencies Accumulated other comprehensive income (loss) is included in partners’ capital in the accompanying consolidated balance sheets and consists of the cumulative currency translation adjustments associated with our international operations. Foreign currency exchange (gains) and losses are included in other (income) expense, net and totaled $0.4 million and $1.7 million during the three-month periods ended March 31, 2021 and March 31, 2020 , respectively. 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. 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 the relevant 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. There were no impairments attributed to continuing operations recorded during the three-month periods ended March 31, 2021 or March 31, 2020. 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. Earnings Per Common Unit Our computations of earnings per common unit are based on the weighted average number of common units outstanding during the applicable period. Basic earnings per common unit are determined by dividing net income (loss) allocated to the common units after deducting the amount allocated to our General Partner (including any 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 distribution 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. Diluted earnings per common 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. For the three-month periods ended March 31, 2021 and March 31, 2020, all unvested phantom units were excluded from the calculation of diluted common units because the impact was anti-dilutive. 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 8 – “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 19, 2021, our General Partner declared a cash distribution attributable to the quarter ended December 31, 2020 of $0.01 per outstanding 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 each of the holders of common units of record as of the close of business on January 29, 2021. New Accounting Pronouncements Standards adopted in 2021 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. On January 1, 2021, we adopted ASU 2019-12. 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 will be effective for us in the first quarter of 2023. 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

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	DISCONTINUED OPERATIONS On July 2, 2020, we completed 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. 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 sales 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 ceased fabricating new compressor packages for sales to third parties or for our own service fleet. The operations associated with the new unit sales business were 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) Three Months Ended 2021 2020 Revenue $ — $ 4,844 Cost of revenues 22 4,817 Depreciation, amortization, and accretion — 238 Impairments of long-lived assets — 5,371 General and administrative expense 40 1,166 Total pretax income (loss) from discontinued operations (62) (6,748) Income tax provision — 16 Total income (loss) from discontinued operations $ (62) $ (6,764) Reconciliation of Major Classes of Assets and Liabilities of the Discontinued Operations to Amounts Presented Separately in the Statement of Financial Position (in thousands) March 31, 2021 December 31, 2020 Carrying amounts of major classes of assets included as part of discontinued operations Inventories $ 32 $ 32 Other Current Assets — 7 Current assets of discontinued operations $ 32 $ 39 Carrying amounts of major classes of liabilities included as part of discontinued operations Accrued liabilities $ 279 $ 345 Current liabilities of discontinued operations $ 279 $ 345

Leases (Notes)	3 Months Ended

Leases [Abstract]
Lessee, Operating 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 up to ten 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. On February 12, 2021, we entered into a build-to-suit agreement for a facility to serve as support for our aftermarket services. The lease on the facility has a ten-year term with initial base rent of $0.5 million per year, and is expected to commence during the second quarter of 2021. 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. Lease costs are included in either cost of revenues or selling, general, and administrative expense depending on the use of the underlying asset.

Lessee, Finance Leases [Text Block]	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 up to ten 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. On February 12, 2021, we entered into a build-to-suit agreement for a facility to serve as support for our aftermarket services. The lease on the facility has a ten-year term with initial base rent of $0.5 million per year, and is expected to commence during the second quarter of 2021. 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. 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 $4.2 million and $4.0 million for the three months ended March 31, 2021 and March 31, 2020, respectively, of which, $1.6 million and $1.8 million respectively, related to short-term leases.

Our Credit Agreement and Senior Note agreements contain certain affirmative and negative covenants, including covenants that restrict the ability to pay dividends or other restricted payments. We are in compliance with all covenants of our credit and senior note agreements as of March 31, 2021. See Note 7 – “Related Party Transactions,” for a discussion of our amounts payable to affiliates and long-term affiliate payable to Spartan Energy Partners LP (“Spartan”). Credit Agreement In June 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. Additionally, on January 29, 2021, the Partnership further amended the Credit Agreement to temporarily increase the size of the reserve to $10.0 million and also required that Spartan backstop all of the Partnership’s outstanding letters of credit. These temporary restrictions expired on April 30, 2021. As of March 31, 2021, we had no balance outstanding under the Credit Agreement and $1.8 million of letters of credit against our Credit Agreement. 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 $13.8 million as of March 31, 2021. See Note 11 – “Subsequent Events” for further information regarding our Credit Agreement. Borrowings under the credit facility are subject to the applicable margin related to (i) LIBOR Rate Loans (as defined in the Credit Agreement) between 3.00% and 3.50% and (ii) Base Rate Loans (as defined in the Credit Agreement) between 2.00% and 2.50%. The commitment fee in respect of the unutilized commitments under the Credit Agreement is 0.50%. 7.25% Senior Notes due 2022 As of March 31, 2021, our 7.25% Senior Notes due 2022 (the “Senior Notes”) had $80.1 million outstanding net of unamortized discounts and unamortized deferred financing costs. Interest on these notes is payable on February 15 and August 15 of each year. The Senior Notes are unsecured obligations, and are guaranteed on a unsecured basis by the Partnership’s subsidiaries that guarantee the Credit Agreement. Our Senior Notes are jointly and severally, and fully and unconditionally, guaranteed by each of the Partnership’s domestic restricted subsidiaries (other than CSI Compressco Finance Inc.) that guarantee the Partnership’s other indebtedness (collectively, the "Guarantor Subsidiaries”). The Senior Notes indenture includes customary provisions for the release of the guarantees by the Guarantor Subsidiaries upon the occurrence of certain allowed events including the release of a guarantor under our revolving credit facility. 7.50% First Lien Notes due 2025 As of March 31, 2021, our First Lien Notes had $399.6 million outstanding net of unamortized discounts, unamortized deferred financing costs and deferred restructuring gains. Interest on these notes is payable on April 1 and October 1 of each year. The First Lien Notes are secured by a first-priority security interest in substantially all of the Partnership’s and its subsidiaries assets, subject to certain permitted encumbrances and exceptions, and are guaranteed on a senior secured basis by each of the Partnership’s U.S. restricted subsidiaries (other than Finance Corp, certain immaterial subsidiaries and certain other excluded U.S. subsidiaries). 10.000%/10.750% Second Lien Notes due 2026 As of March 31, 2021, our Second Lien Notes had $158.9 million outstanding, net of unamortized discounts, unamortized deferred financing costs and deferred restructuring gains. Interest on the Second Lien Notes is payable on April 1 and October 1 of each year. The Second Lien Notes are secured by a second-priority security interest in substantially all of the Partnership’s and its subsidiaries assets, subject to certain permitted encumbrances and exceptions, and are guaranteed on a senior secured basis by each of the Partnership’s U.S. restricted subsidiaries (other than Finance Corp and certain other excluded U.S. subsidiaries). In connection with the payment of PIK Interest (as defined below), if any, in respect of the Second Lien Notes, the issuers will be entitled, to increase the outstanding aggregate principal amount of the Second Lien Notes or issue additional notes (“PIK notes”) under the Second Lien Notes indenture on the same terms and conditions as the already outstanding Second Lien Notes. Interest will accrue at (1) the annual rate of 7.250% payable in cash, plus (2) at the election of the Issuers (made by delivering a notice to the Second Lien Trustee not less than five business days prior to the record date), the annual rate of (i) 2.750% payable in cash (together with the annual rate set forth in clause (1), the “Cash Interest Rate”) or (ii) 3.500% payable by increasing the principal amount of the outstanding Second Lien Notes or by issuing additional PIK notes, in each case rounding up to the nearest $1.00 (such increased principal amount or additional PIK notes, the “PIK Interest”). The indentures governing our First Lien Notes and Second Lien Notes contain customary covenants restricting our ability and the ability of our restricted subsidiaries to: (i) pay distributions on, purchase, or redeem our common units, make certain investments and other restricted payments, or purchase or redeem any subordinated debt; (ii) incur or guarantee additional indebtedness or issue certain kinds of preferred equity securities; (iii) create or incur certain liens securing indebtedness; (iv) sell assets, including dispositions of the collateral securing our First Lien Notes and Second Lien Notes; (v) consolidate, merge, or transfer all or substantially all of our assets; (vi) enter into transactions with affiliates; and (vii) enter into agreements that restrict distributions or other payments from our restricted subsidiaries to us. Our Second Lien Notes indenture further restricts our ability to make distributions in respect of our common units in any amount exceeding $0.04 per common unit per year, unless such increased distribution is funded by proceeds from an equity offering. These covenants are subject to a number of important limitations and exceptions, including certain provisions permitting us, subject to the satisfaction of certain conditions, to transfer assets to certain of our unrestricted subsidiaries. The indentures also contain customary events of default and acceleration provisions relating to events of default, which provide that upon an event of default under the indentures, the Trustee or the holders of at least 25% in aggregate principal amount of the then outstanding First Lien Notes and Second Lien Notes may declare all of the First Lien Notes and Second Lien Notes to be due and payable immediately. During the fourth quarter of 2020, the Partnership elected to increase the principal amount outstanding by $1.6 million through the issuance of PIK notes. This amount is included in the balance outstanding as of March 31, 2021. See Note 11 – “Subsequent Events” for further information regarding our Second Lien Notes.

Related Party Transactions [Abstract]
Related Party Transactions	RELATED PARTY TRANSACTIONS 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 retained 5.2 million common units of the Partnership. Omnibus Agreement Under the terms of the Omnibus Agreement, our General Partner provided 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 provided personnel and services necessary for the conduct of certain of our Latin American-based businesses. In addition, under the Omnibus Agreement, TETRA provided 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 reimbursed our General Partner and TETRA for services they provide to us. Upon the closing of the GP Sale, the Omnibus Agreement terminated in accordance with its terms. Beginning in February 2021, we will reimburse our General Partner under the terms of our partnership agreement for any expenses and expenditures incurred or payments made on our behalf, including, operating expenses related to our operations and for the provision of various general and administrative services for our benefit. Transition Services Agreement TETRA will 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. Spartan and General Partner Ownership As of March 31, 2021, Spartan’s ownership interest in us was approximately 23%, with the common units held by the public representing an approximate 65% interest in us. 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 of up to $15.0 million of new compression 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. In December 2020, TETRA sold these compressors and assigned the corresponding leases to Spartan. As of March 31, 2021, the financing obligation owed to Spartan was $11.3 million and is included in accounts payable to affiliate and other and other long-term liabilities in our consolidated balance sheet as of March 31, 2021. The balances were included in accrued liabilities and other long-term liabilities in our consolidated balance sheet as of December 31,2020. Imputed interest expense recognized for the three-month period ended March 31, 2021 was $0.6 million. Mexico Payroll Affiliate In January 2021, the Partnership entered into an agreement to purchase a TETRA-owned entity, which administers payroll in Mexico, for consideration of approximately $0.4 million. The difference between the fair value of the affiliate and TETRA’s historic carrying value of the affiliates’ net assets was recorded as a capital distribution. The associated liability is included in accounts payable on the consolidated balance sheet as of March 31, 2021 and was paid in April 2021.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Fair value is defined by ASC Topic 820 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 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 March 31, 2021, we had the following foreign currency derivative contract outstanding relating to a portion of our foreign operations: Derivative contracts US Dollar Notional Amount Traded Exchange Rate Settlement Date (In Thousands) Forward sale Mexican peso $ 5,763 20.74 April 5, 2021 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 our foreign currency derivative instruments contains credit risk related contingent features that would require us to post assets or collateral for contracts that are classified as liabilities. During the three-month periods ended March 31, 2021 and March 31, 2020, we recognized $(0.1) million and $(1.4) million, respectively, of net (gains) losses associated with our foreign currency derivatives program. These amounts are 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. The carrying and fair value of our debt, excluding unamortized debt issuance costs, are as follows (in thousands): March 31, 2021 December 31, 2020 Carrying Value Fair Value Carrying Value Fair Value (In Thousands) 7.25% Senior Notes $ 80,722 $ 76,686 $ 80,722 $ 67,274 7.50% First Lien Notes 400,000 408,000 400,000 369,680 10.000%/10.750% Second Lien Notes 157,162 138,303 157,162 114,728 $ 637,884 $ 622,989 $ 637,884 $ 551,682

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. Our operations are treated as a partnership for federal tax purposes with each partner being separately taxed on its share of 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. Certain of our operations are located outside of the U.S., and the Partnership, through its foreign subsidiaries, is responsible for income taxes in these countries. Our effective tax rate for the three-month period ended March 31, 2021, was negative (11.7)% primarily attributable to taxes in certain foreign jurisdictions and Texas gross margin taxes combined with losses generated in entities for which no related tax benefit has been recorded. Included in our deferred tax assets are net operating loss carryforwards and tax credits that are available to offset future income tax liabilities in the U.S. as well as in certain foreign jurisdictions.

Accounting Policies [Abstract]
Nature of Operations [Text Block]	Organization 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 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 United States 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 2 – “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.
Inventory, Policy [Policy Text Block]	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
Impairment or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [Policy Text Block]	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 the relevant 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. There were no impairments attributed to continuing operations recorded during the three-month periods ended March 31, 2021 or March 31, 2020.
Consolidation policy	Presentation Our unaudited consolidated financial statements include the accounts of our wholly owned subsidiaries. All intercompany balances and transactions have been eliminated. In the opinion of our management, our unaudited consolidated financial statements as of March 31, 2021, and for the three-month periods ended March 31, 2021 and 2020, include all normal recurring adjustments that are necessary to provide a fair statement of our results for these interim periods. Operating results for the three-month period ended March 31, 2021 are not necessarily indicative of results that may be expected for the twelve months ended December 31, 2021. The accompanying unaudited consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the U.S. Securities and Exchange Commission (“SEC”) and do not include all information and footnotes required by U.S. generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. These financial statements should be read in conjunction with the financial statements for the year ended December 31, 2020 and notes thereto included in our Annual Report on Form 10-K , which we filed with the SEC on March 4, 2021.
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.
Foreign currencies policy	Foreign Currencies Accumulated other comprehensive income (loss) is included in partners’ capital in the accompanying consolidated balance sheets and consists of the cumulative currency translation adjustments associated with our international operations. Foreign currency exchange (gains) and losses are included in other (income) expense, net and totaled $0.4 million and $1.7 million during the three-month periods ended March 31, 2021 and March 31, 2020 , respectively.
Earnings per common unit policy	Earnings Per Common Unit Our computations of earnings per common unit are based on the weighted average number of common units outstanding during the applicable period. Basic earnings per common unit are determined by dividing net income (loss) allocated to the common units after deducting the amount allocated to our General Partner (including any 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 distribution 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. Diluted earnings per common 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. For the three-month periods ended March 31, 2021 and March 31, 2020, all unvested phantom units were excluded from the calculation of diluted common units because the impact was anti-dilutive.
Revenue [Policy Text Block]
Fair Value of Financial Instruments, Policy [Policy Text Block]	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 8 – “Fair Value Measurements” for further discussion.
Distributions policy	Distributions On January 19, 2021, our General Partner declared a cash distribution attributable to the quarter ended December 31, 2020 of $0.01 per outstanding 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 each of the holders of common units of record as of the close of business on January 29, 2021.
New accounting pronouncements policy	New Accounting Pronouncements Standards adopted in 2021 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. On January 1, 2021, we adopted ASU 2019-12. 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.
