Accounting Policies [Abstract]
Basis of Presentation and Significant 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, transportation, processing, and storage. We sell standard and custom-designed compressor packages and 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 United States as well as in a number of foreign countries, including Mexico, Canada, and Argentina. We design and fabricate a majority of the compressor packages that we use to provide compression services or that we sell to customers. 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 June 30, 2019 , and for the three and six month periods ended June 30, 2019 and 2018 , 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 and six month periods ended June 30, 2019 are not necessarily indicative of results that may be expected for the twelve months ended December 31, 2019 . 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, 2018 and notes thereto included in our 2018 Annual Report on Form 10-K, which we filed with the SEC on March 4, 2019. Segments Our General Partner has concluded that we operate in one business segment. Significant Accounting Policies We have added policies for the recording of leases in conjunction with the adoption of the new lease standard discussed in our "Leases" and "New Accounting Pronouncements" sections below. Other than the additional lease policies described herein, there have been no significant changes in our accounting policies or the application of these policies. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of 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. Impairments and Other Charges During the three month period ending June 30, 2019, we recorded impairments of $2.3 million on certain units of our low-horsepower compression 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. 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. 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 $(0.04) million and $(1.0) million during the three and six month periods ended June 30, 2019 , respectively, and $0.5 million and $(0.6) million during the three and six month periods ended June 30, 2018 , respectively. 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 June 30, 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, 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. 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 and six month periods ended June 30, 2019 and June 30, 2018 , all unvested phantom units were excluded from the calculation of diluted common units because the impact was anti-dilutive. Diluted earnings per common unit are 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, discussed in Note D - "Series A Convertible Preferred Units", had been converted as of the beginning of the period presented. The number of common units that may be issued upon future conversion of the Preferred Units is excluded from the calculation of diluted common units for the three and six month periods ended June 30, 2019 and 2018 as the impact would be anti-dilutive. Distributions On January 22, 2019 , our General Partner declared a cash distribution attributable to the quarter ended December 31, 2018 of $0.01 per common unit. This distribution equates to a distribution of $0.04 per outstanding common unit on an annualized basis. Also on January 22, 2019 , our General Partner approved the paid in kind distribution of 85,565 Preferred Units attributable to the quarter ended December 31, 2018 in accordance with the provisions of our partnership agreement, as amended. These distributions were paid on February 14, 2019 , to each of the holders of common units and the holders of the Preferred Units in the aggregate, respectively, of record as of the close of business on February 1, 2019 . On April 18, 2019 , our General Partner declared a cash distribution attributable to the quarter ended March 31, 2019 of $0.01 per common unit. This distribution equates to a distribution of $0.04 per outstanding common unit on an annualized basis. Also on April 18, 2019 , our General Partner approved the paid in kind distribution of 59,953 Preferred Units attributable to the quarter ended March 31, 2019 in accordance with the provisions of our partnership agreement, as amended. These distributions were paid on May 15, 2019 , to each of the holders of common units and the holders of the Preferred Units in the aggregate, respectively, of record as of the close of business on May 1, 2019 . New Accounting Pronouncements Standards adopted in 2019 In February 2016, the FASB issued Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)" to increase comparability and transparency among different organizations. Organizations are required to recognize right-of-use lease assets and lease liabilities in the balance sheet related to the right to use the underlying asset for the lease term. In addition, through improved disclosure requirements, ASC 842 will enable users of financial statements to further understand the amount, timing, and uncertainty of cash flows arising from leases. We adopted the standard effective January 1, 2019. The standard had a material impact on our consolidated balance sheet, specifically, the reporting of our operating leases. We chose to transition using a modified retrospective approach which allows for the recognition of a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption rather than the earliest period presented. Comparative information is reported under the accounting standards that were in effect for those periods. In addition, upon transition, we elected the package of practical expedients, which allows us to continue to apply historical lease classifications to existing contracts. Upon adoption, we recognized $8.3 million in operating right-of-use assets, $3.5 million in accrued liabilities, and $4.8 million in operating lease liabilities. Refer to Note J - “Leases” for further information on our leases. In February 2018, the FASB issued ASU 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220)" that gives entities the option to reclassify the income tax effects of the Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. This was effective for us on January 1, 2019, however, as we do not have associated tax effects in accumulated other comprehensive income, there was no impact. In June 2018, the FASB issued ASU 2018-07, “Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting” to align the measurement and classification guidance for share-based payments to nonemployees with the guidance currently applied to employees, with certain exceptions. We adopted this ASU during the three months ended March 31, 2019, with no material impact to 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. ASU 2016-13 has an effective date of the first quarter of fiscal 2020. We are currently assessing the potential effects of these changes to our consolidated financial statements. In August 2018, the FASB issued 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. ASU 2018-15 is effective for interim and annual reporting periods beginning after December 15, 2019, and early adoption is permitted. We are currently assessing the potential effects of these changes to our consolidated financial statements.

Series A Preferred Units [Abstract]
Series A Convertible Preferred Units	SERIES A CONVERTIBLE PREFERRED UNITS During 2016, we issued an aggregate of 6,999,126 Preferred Units for a cash purchase price of $11.43 per Preferred Unit (the “Issue Price”). One of the purchasers was TETRA, which purchased 874,891 of the Preferred Units at the aggregate Issue Price of $10.0 million . Unless otherwise redeemed for cash, a ratable portion of the Preferred Units has been, and may be, converted into common units on the eighth day of each month over a period of thirty months that began in March 2017 and will end in August 2019 (each, a “Conversion Date”). Based on the number of Preferred Units outstanding as of June 30, 2019 , the maximum aggregate number of common units that could be required to be issued pursuant to the conversion provisions of the Preferred Units is approximately 4.3 million common units; however, the Partnership may, at its option, pay cash, or a combination of cash and common units, to the holders of Preferred Units instead of issuing common units on any Conversion Date, subject to certain restrictions as described in the Second Amended and Restated Partnership Agreement and the Credit Agreement. Beginning with the January 2019 Conversion Date, we have elected to redeem the remaining Preferred Units for cash, resulting in 1,870,681 Preferred Units being redeemed during the six months ended June 30, 2019 for $22.5 million , which includes approximately $1.1 million of redemption premium that was paid and charged to other (income) expense, net in the accompanying consolidated statements of operations. The total number of Preferred Units outstanding as of June 30, 2019 was 751,736 . The last redemption of the remaining 375,868 Preferred Units, along with a final cash payment made in lieu of paid in kind units for the quarter ended June 30, 2019 , for an aggregate cash payment of $5.0 million , is scheduled to occur on August 8, 2019. The fair value of the Preferred Units is classified as a long-term liability on our consolidated balance sheets. The fair value of the Preferred Units as of June 30, 2019 was $9.0 million . Based on the conversion provisions of the Preferred Units, and using the Conversion Price calculated as of June 30, 2019 , the theoretical number of common units that would be issued if all of the outstanding Preferred Units were converted on June 30, 2019 on the same basis as the monthly conversions would be approximately 2.7 million common units, with an aggregate market value of $9.7 million . A $1 decrease in the Conversion Price would result in the issuance of approximately 1.3 million additional common units pursuant to these conversion provisions.

Fair Value Disclosures [Abstract]
Market Risks and Derivative Contracts	FAIR VALUE MEASUREMENTS Financial Instruments Preferred Units The Preferred Units are valued using a lattice modeling technique that, among a number of lattice structures, includes significant unobservable items (a Level 3 fair value measurement). These unobservable items include (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 utilizes market information related to the debt yields of comparable peer companies, and (iii) a future conversion price analysis. Derivative Contracts As of June 30, 2019 , 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 $ 7,858 19.09 7/19/2019 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 instruments are based on quoted market values (a Level 2 fair value measurement). The fair values of our foreign currency derivative instruments as of June 30, 2019 and December 31, 2018 , are as follows: Foreign currency derivative instruments Balance Sheet Fair Value at Location June 30, 2019 December 31, 2018 (In Thousands) Forward sale contracts Current assets $ 64 $ — Forward sale contracts Current liabilities — (98 ) Net asset (liability) $ 64 $ (98 ) None of our 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 three and six month periods ended June 30, 2019 we recognized $0.2 million and $0.3 million , respectively, of net (gains) losses associated with our foreign currency derivative program, and such amounts are included in other (income) expense, net, in the accompanying consolidated statement of operations. During the three and six month periods ended June 30, 2018 , we recognized $0.7 million and $0.2 million , respectively, of net (gains) losses associated with our foreign currency derivative program, and such amounts are included in other (income) expense, net, in the accompanying consolidated statement of operations. A summary of these recurring fair value measurements by valuation hierarchy as of June 30, 2019 and December 31, 2018 is as follows: Fair Value Measurements Using Description Total as of Quoted Prices Significant Significant (In Thousands) Series A Preferred Units $ (9,000 ) $ — $ — $ (9,000 ) Asset for foreign currency derivative contracts 64 — 64 — $ (8,936 ) Fair Value Measurements Using Quoted Prices Significant Significant Description Total as of (In Thousands) Series A Preferred Units $ (30,900 ) $ — $ — $ (30,900 ) Liability for foreign currency derivative contracts (98 ) — (98 ) — $ (30,998 ) The fair values of cash, accounts receivable, accounts payable, accrued liabilities, short-term borrowings, and variable-rate long-term debt pursuant to our Credit Agreement approximate their carrying amounts. The fair values of our publicly traded long-term 7.25% Senior Notes at June 30, 2019 and December 31, 2018 were approximately $267.1 million and $266.3 million , respectively. Those fair values compare to aggregate principal amounts of such notes at June 30, 2019 and December 31, 2018 of $295.9 million . The fair values of our long-term 7.50% Senior Secured Notes at June 30, 2019 and December 31, 2018 were approximately $344.8 million and $332.5 million , respectively. These fair values compare to an aggregate principal amount of such notes at June 30, 2019 and December 31, 2018 of $350.0 million . We based the fair values of our 7.25% Senior Notes and our 7.50% Senior Secured Notes as of June 30, 2019 on recent trades for these notes.

Related Party Transactions	RELATED PARTY TRANSACTIONS Omnibus Agreement 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. TETRA and General Partner Ownership As of June 30, 2019 , TETRA's ownership interest in us was approximately 34% of the outstanding common units, 12.6% of the outstanding Preferred Units, and an approximately 1.4% general partner interest, through which it holds incentive distribution rights. Other Sources of Financing In February 2019, we entered into a transaction with TETRA whereby TETRA has agreed to fund the construction of and purchase up to $15.0 million of new compressor services equipment and lease it to us in exchange for a monthly rental fee. As of June 30, 2019 , pursuant to this arrangement, $11.1 million has been funded by TETRA for the construction of new compressor equipment and is included in long-term affiliate payable in our consolidated balance sheet.

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 six month period ended June 30, 2019 , was negative 31.3% 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. In addition, the application of ASC 740-270 "Income Taxes - Interim Reporting," resulted in an accrual of current income taxes for the six month period ended June 30, 2019 equal to approximately the full year estimate. 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.

While the outcome of any lawsuits or other proceedings against us cannot be predicted with certainty, management does not consider it reasonably possible that a loss resulting from such lawsuits or proceedings in excess of any amounts accrued has been incurred that is expected to have a material adverse effect on our financial condition, results of operations, or cash flows.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	REVENUE FROM CONTRACTS WITH CUSTOMERS Performance Obligations. 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. 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. 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 such products or services is not expected 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. As of June 30, 2019 , we had $45.3 million of remaining performance obligations related to our compression service contracts. As a practical expedient, thi s amount does not reflect revenue for compression service contracts whose original expected duration is less than 12 months an d does not consider the effects of the time value of money . The remaining performance obligations, and associated revenues, will be recognized through 2023 as follows: 2019 2020 2021 2022 2023 Total (In Thousands) Compression service contracts remaining performance obligations $ 19,830 $ 19,279 $ 6,108 $ 101 $ — $ 45,318 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. Equipment Sales & Aftermarket Services. Equipment sales and most aftermarket service revenues are recognized at a point in time when we transfer control of our products and complete the delivery of services to our customers. 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. Our contract asset balances, primarily associated with these documentation requirements, were $8.0 million and $5.9 million as of June 30, 2019 and December 31, 2018 , respectively. 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. The following table reflects changes in our contract liabilities for the periods indicated: Six Months Ended 2019 2018 (In Thousands) Unearned income, beginning of period $ 24,898 $ 15,526 Additional unearned income 83,640 57,509 Revenue recognized (77,708 ) (44,594 ) Unearned income, end of period $ 30,830 $ 28,441 During the six months ended June 30, 2019 , we recognized in product sales revenue $18.7 million from unearned income that was deferred as of December 31, 2018. During the six months ended June 30, 2018, we recognized in product sales revenue of $13.8 million from unearned income that was deferred as of our adoption of ASC 606 on January 1, 2018. Contract Costs. As of June 30, 2019 , contract costs are immaterial. Disaggregation of Revenue. We disaggregate revenue from contracts with customers by geography based on the following table.

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. We do not have leases that have not yet commenced that create significant rights and obligations.

Accounting Policies [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 June 30, 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, 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	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 June 30, 2019 , and for the three and six month periods ended June 30, 2019 and 2018 , 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 and six month periods ended June 30, 2019 are not necessarily indicative of results that may be expected for the twelve months ended December 31, 2019 . 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, 2018 and notes thereto included in our 2018 Annual Report on Form 10-K, which we filed with the SEC on March 4, 2019.
Use of estimates policy	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of 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 $(0.04) million and $(1.0) million during the three and six month periods ended June 30, 2019 , respectively, and $0.5 million and $(0.6) million during the three and six month periods ended June 30, 2018 , 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 and six month periods ended June 30, 2019 and June 30, 2018 , all unvested phantom units were excluded from the calculation of diluted common units because the impact was anti-dilutive. Diluted earnings per common unit are 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, discussed in Note D - "Series A Convertible Preferred Units", had been converted as of the beginning of the period presented. The number of common units that may be issued upon future conversion of the Preferred Units is excluded from the calculation of diluted common units for the three and six month periods ended June 30, 2019 and 2018 as the impact would be anti-dilutive.
Distributions policy	Distributions On January 22, 2019 , our General Partner declared a cash distribution attributable to the quarter ended December 31, 2018 of $0.01 per common unit. This distribution equates to a distribution of $0.04 per outstanding common unit on an annualized basis. Also on January 22, 2019 , our General Partner approved the paid in kind distribution of 85,565 Preferred Units attributable to the quarter ended December 31, 2018 in accordance with the provisions of our partnership agreement, as amended. These distributions were paid on February 14, 2019 , to each of the holders of common units and the holders of the Preferred Units in the aggregate, respectively, of record as of the close of business on February 1, 2019 . On April 18, 2019 , our General Partner declared a cash distribution attributable to the quarter ended March 31, 2019 of $0.01 per common unit. This distribution equates to a distribution of $0.04 per outstanding common unit on an annualized basis. Also on April 18, 2019 , our General Partner approved the paid in kind distribution of 59,953 Preferred Units attributable to the quarter ended March 31, 2019 in accordance with the provisions of our partnership agreement, as amended. These distributions were paid on May 15, 2019 , to each of the holders of common units and the holders of the Preferred Units in the aggregate, respectively, of record as of the close of business on May 1, 2019 .
New accounting pronouncements policy	New Accounting Pronouncements Standards adopted in 2019 In February 2016, the FASB issued Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)" to increase comparability and transparency among different organizations. Organizations are required to recognize right-of-use lease assets and lease liabilities in the balance sheet related to the right to use the underlying asset for the lease term. In addition, through improved disclosure requirements, ASC 842 will enable users of financial statements to further understand the amount, timing, and uncertainty of cash flows arising from leases. We adopted the standard effective January 1, 2019. The standard had a material impact on our consolidated balance sheet, specifically, the reporting of our operating leases. We chose to transition using a modified retrospective approach which allows for the recognition of a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption rather than the earliest period presented. Comparative information is reported under the accounting standards that were in effect for those periods. In addition, upon transition, we elected the package of practical expedients, which allows us to continue to apply historical lease classifications to existing contracts. Upon adoption, we recognized $8.3 million in operating right-of-use assets, $3.5 million in accrued liabilities, and $4.8 million in operating lease liabilities. Refer to Note J - “Leases” for further information on our leases. In February 2018, the FASB issued ASU 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220)" that gives entities the option to reclassify the income tax effects of the Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. This was effective for us on January 1, 2019, however, as we do not have associated tax effects in accumulated other comprehensive income, there was no impact. In June 2018, the FASB issued ASU 2018-07, “Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting” to align the measurement and classification guidance for share-based payments to nonemployees with the guidance currently applied to employees, with certain exceptions. We adopted this ASU during the three months ended March 31, 2019, with no material impact to 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. ASU 2016-13 has an effective date of the first quarter of fiscal 2020. We are currently assessing the potential effects of these changes to our consolidated financial statements. In August 2018, the FASB issued 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. ASU 2018-15 is effective for interim and annual reporting periods beginning after December 15, 2019, and early adoption is permitted. We are currently assessing the potential effects of these changes to our consolidated financial statements.

Lessee, Operating 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 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. We do not have 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. Components of 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), were $1.9 million and $3.7 million for the three and six month periods ended June 30, 2019 , respectively, of which, $0.5 million and $1.0 million respectively, related to short-term leases.
