Notes to Financial Statements [Abstract]
Formation of the Partnership and Description of Business	ORGANIZATION AND OPERATIONS CSI Compressco LP (formerly known as Compressco Partners, L.P.), 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 oilfield fluid pump systems, 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 and that we sell to customers. 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. In April 2017, our General Partner announced a reduction of approximately 50% in the level of cash distributions on our common units beginning with the quarter ended March 31, 2017. In May 2017, we entered into an amendment of the agreement governing our bank revolving credit facility (as amended, the "Credit Agreement") by, among other things, favorably amending certain covenants. (See Note D - Long-Term Debt and Other Borrowings.) We have reviewed our financial forecasts as of March 1, 2018 for the subsequent twelve month period, which consider the amended covenants and the current distribution levels to our common unitholders. Based on these financial forecasts, which are based on the current market conditions as of March 1, 2018 , we believe that we will have adequate liquidity, earnings, and operating cash flows to fund our operations and debt obligations and maintain compliance with our debt covenants through March 1, 2019.

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 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. The impact of such reclassifications was not significant to the prior year's overall presentation. Cash Equivalents We consider all highly liquid cash investments with maturities of three months or less when purchased to be cash equivalents. Financial Instruments The fair values of our financial instruments, which may include cash, accounts receivable, amounts outstanding under our variable rate bank credit facility, accounts payable and accrued liabilities, approximate their carrying amounts. 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. As a result of the outstanding balances under our variable rate revolving credit facility, we face market risk exposure related to changes in applicable interest rates. Although we have no interest rate swap contracts outstanding to hedge this potential risk exposure, we have entered into certain fixed interest rate notes, which are scheduled to mature in 2022 and which mitigate this risk on our total outstanding borrowings. Significant Customers During 2017 and 2016, ConocoPhillips accounted for approximately 11.0% of our revenues. During 2015 , no individual customer accounted for 10% or more of our revenues. Foreign Currencies We have designated the Canadian dollar and Argentine peso as the functional currencies for our operations in Canada and Argentina, respectively. 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 and (losses) are included in other expense and totaled $48,000 , $(1.6) million , and $(2.0) million during the years ended December 31, 2017 , 2016 , and 2015 , respectively. Allowances for Doubtful Accounts Allowances for doubtful accounts are determined on a specific identification basis when we believe that the collection of specific amounts owed to us is not probable. The changes in allowances for doubtful accounts are as follows: Year Ended December 31, 2017 2016 2015 (In Thousands) At beginning of period $ 2,253 $ 1,973 $ 1,496 Activity in the period: Provision for doubtful accounts 968 1,704 508 Account (chargeoffs) recoveries, net (2,399 ) (1,424 ) (31 ) At end of period $ 822 $ 2,253 $ 1,973 Inventories Inventories consist primarily of compressor package parts and supplies and work in process and are stated at the lower of cost or market 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. Work in progress inventories consist primarily of new compressor packages located at our fabrication facility in Midland, Texas. We write down the value of inventory by an amount equal to the difference between its cost and its estimated market value. Components of inventories as of December 31, 2017 , and December 31, 2016 , are as follows: December 31, 2017 December 31, 2016 (In Thousands) Parts and supplies $ 31,703 $ 25,932 Work in progress 10,580 5,510 Total inventories $ 42,283 $ 31,442 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, 2017 , 2016 , and 2015 was $66.0 million , $68.8 million , and $71.7 million , respectively. Construction in progress as of December 31, 2017 consists primarily of new compressor packages under fabrication and capital expenditures that sustain the capacity of our existing fleet. Construction in progress as of December 31, 2016 consists primarily of capitalized system software development costs incurred during 2016. Interest capitalized for the years ended December 31, 2017 , 2016 , and 2015 was $0.6 million , $0.2 million , and $0.0 million , respectively. Intangible Assets other than Goodwill Trademarks/trade names, customer relationships, and other intangible assets are recorded on the basis of cost and 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 $3.2 million , $3.4 million , and $6.8 million for the years ended December 31, 2017 , 2016 , and 2015 , respectively, 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 for 2018 , $2.9 million for 2019 , $2.9 million for 2020 , $2.9 million for 2021 , and $2.9 million for 2022 . 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. See "Impairments of Long-Lived Assets" section below. Goodwill Goodwill represents the excess of cost over the fair value of the net assets of businesses acquired in purchase transactions. Prior to the impairment of remaining goodwill as of March 31, 2016, we performed a goodwill impairment test on an annual basis or whenever indicators of impairment were present. We performed the annual test of goodwill impairment following the fourth quarter of each year. The assessment for goodwill impairment begins with a qualitative assessment of whether it is “more likely than not” that the fair value of our business is less than its carrying value. This qualitative assessment requires the evaluation, based on the weight of evidence, of the significance of all identified events and circumstances. During 2015, and continuing into 2016, global oil and natural gas commodity prices, particularly crude oil, were significantly reduced. These low commodity prices had a negative impact on industry drilling and capital expenditure activity, which affected the demand for a portion of our products and services. The accompanying decrease in the price of our common units during the last half of 2015 and early 2016 also resulted in an overall reduction in our market capitalization. Based on this qualitative assessment, we determined that, due to the decline in the price of our common units that resulted in our market capitalization being less than the book value of our consolidated partners' capital balance as of December 31, 2015 and March 31, 2016, it was “more likely than not” that the fair value of our business was less than its carrying value as of these dates. When the qualitative analysis indicates that it is “more likely than not” that our business’ fair value is less than its carrying value, the resulting goodwill impairment test consists of a two-step accounting test being performed. The first step of the impairment test is to compare the estimated fair value with the recorded net book value (including goodwill) of our business. If the estimated fair value is higher than the recorded net book value, no impairment is deemed to exist and no further testing is required. If, however, the estimated fair value is below the recorded net book value, an impairment loss is calculated by comparing the recorded net book value of goodwill to our estimated implied fair value of that goodwill. Our estimates of our fair value, when required, are based on a combination of an income and market approach. These estimates are imprecise and are subject to our estimates of our future cash flows and our judgment as to how these estimated cash flows translate into our estimated fair value. These estimates and judgments are affected by numerous factors, including the general economic environment at the time of our assessment, which affects our overall market capitalization. Our management must apply judgment in determining the estimated fair value for purposes of performing the goodwill impairment test. Management uses all available information to make these fair value determinations, including the present value of expected future cash flows using discount rates commensurate with the risks involved in the assets. The resultant fair values calculated are then compared to observable metrics for other companies in our industry or on mergers and acquisitions in our industry, to determine whether those valuations, in our judgment, appear reasonable. The accounting principles regarding goodwill acknowledge that the observed market prices of individual trades of a company’s stock (and thus its computed market capitalization) may not be representative of the fair value of the company as a whole. Substantial value may arise from the ability to take advantage of synergies and other benefits that flow from control over another entity. Consequently, measuring the fair value of a collection of assets and liabilities that operate together in a controlled entity is different from measuring the fair value of a single share of that entity’s common stock. Therefore, once the fair value of the reporting units was determined, we also added a control premium to the calculations. This control premium is judgmental and is based on observed mergers and acquisitions in our industry. As part of our internal annual business outlook that we performed during 2015 and 2016, we considered changes in the global economic environment that affected our common unit price and market capitalization. As a result of the annual goodwill impairment test process described above, we recorded impairments of goodwill of $92.3 million as of December 31, 2015 and $92.4 million as of March 31, 2016 . As of December 31, 2015, as a result of decreased demand for our products and services due to decreased oil and natural gas commodity prices, and due to decrease in the price of our common units, we determined that it was "more likely than not" that our fair value was less than our net book value as of December 31, 2015. With regard to the 2016 impairment, due to the decrease in the price of our common units during the first three months of 2016, our market capitalizations as of March 31, 2016, was again below our recorded net book value, including remaining goodwill. In addition, the continuing low oil and natural gas commodity price environment resulted in a further negative impact on demand for the products and services for each of our reporting units. As a result of these factors, we determined that it was “more likely than not” that our fair value was less than our net book value as of March 31, 2016. As of December 31, 2017 , the carrying amount of goodwill is $0.0 million , after giving effect to the $233.5 million of accumulated impairment losses. The changes in the carrying amount of goodwill are as follows: Year Ended December 31, 2017 2016 2015 (In Thousands) Balance, beginning of year $ — $ 92,402 $ 233,548 Goodwill acquired during the year — — — Goodwill adjustments — (92,402 ) (141,146 ) Balance, end of year $ — $ — $ 92,402 Impairments of Long-Lived Assets 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 the first quarter of 2016, as a result of continuing decreased demand as a result of current market conditions, we recorded impairments of approximately $7.9 million associated with certain identified intangible assets. During the fourth quarter of 2016, as a result of fire damage to compressor packages, we recorded impairments of approximately $2.4 million associated with certain identified compressor units. This amount was charged to Long-Lived Asset Impairment expense in the accompanying consolidated statement of operations. Revenue Recognition We recognize revenue using the following criteria: (a) persuasive evidence of an exchange arrangement exists; (b) delivery has occurred or services have been rendered; (c) the buyer’s price is fixed or determinable; and (d) collectability is reasonably assured. 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. Collections associated with progressive billings to customers for the construction of compression equipment is included in unearned income in the consolidated balance sheets. Compression and Related Services Revenues and Costs Our compression and related services revenues include revenues from our U.S. corporate subsidiaries' operating lease agreements with customers. For the three years in the period ended December 31, 2017 , the following operating lease revenues and associated costs were included in compression and related service revenues and cost of compression and related services, respectively, in the accompanying consolidated statements of operations. As a result of our customers entering into compression service contracts, our revenues from rental contracts have decreased during the year ended December 31, 2017 compared to the prior years. Year Ended December 31, 2017 2016 2015 (In Thousands) Rental revenue $ 38,720 $ 42,644 $ 117,540 Rental expenses $ 17,560 $ 25,039 $ 66,040 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, nonexecutive officers, consultants, and directors of our general partner. Total equity-based compensation expense for the three years ended December 31, 2017 , 2016 , and 2015 , was $1.2 million , $3.0 million , and $2.2 million , respectively. For further discussion of equity-based compensation, see Note I - 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 of the United States 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. Beginning in 2015, a portion of the carrying value of certain deferred tax assets is subjected to a valuation allowance. See Note G - Income Taxes for further discussion. 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 United States 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 accumulated other comprehensive income (loss) during the three years ended December 31, 2017 , December 31, 2016 , and December 31, 2015 is as follows: Year Ended December 31, 2017 2016 2015 (In Thousands) Balance, beginning of year $ (10,411 ) $ (8,393 ) $ (3,336 ) Foreign currency translation adjustment, net of tax of $0 in 2017, 2016, and 2015 (1,078 ) (2,018 ) (5,057 ) Balance, end of year $ (11,489 ) $ (10,411 ) $ (8,393 ) Activity within accumulated other comprehensive income includes no reclassifications to net income. Allocation of Net Income Our net income is allocated to partners’ capital accounts in accordance with the provisions of the Partnership Agreement. Fair Value Measurements Fair 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. generally accepted accounting principles ("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. We utilize fair value measurements to account for certain items and account balances within our consolidated financial statements. Fair value measurements are utilized in the determination of the carrying value of our Preferred Units (a Level 3 fair value measurement), which were issued in August and September 2016. 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 as determined by our counterparty financial institution (a level 2 fair value measurement). 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 and goodwill (a Level 3 fair value measurement), and for the impairment of long-lived assets, including goodwill (a level 3 fair value measurement). The fair value of certain of our financial instruments, which may include cash, accounts receivable, short-term borrowings, and variable-rate long-term debt pursuant to our bank credit agreement, approximate their carrying amounts. The fair values of our publicly traded long-term 7.25% Senior Notes at December 31, 2017 and December 31, 2016 , were approximately $279.7 million and $278.2 million (a level 2 fair value measurement). Those fair values compared to an aggregate principal amount of such notes at December 31, 2017 and 2016 of $295.9 million . 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. The fair valuation of our Preferred Units liability is increased by, among other factors, projected increases in our common unit price, and by increases in the volatility and decreases in the debt yields of comparable peer companies. Increases (or decreases) in the fair value of our Preferred Units will increase (decrease) the associated liability and result in future adjustments to earnings for the associated valuation losses (gains). A summary of these recurring fair value measurements as of December 31, 2017 and 2016 , is as follows: Fair Value Measurements Using Description Total as of December 31, 2017 Quoted Prices Significant Significant (In Thousands) Series A Preferred Units $ (70,260 ) $ — $ — $ (70,260 ) Asset for foreign currency derivative contracts 130 — 130 — Liability for foreign currency derivative contracts (10 ) — (10 ) — $ (70,140 ) Fair Value Measurements Using Description Total as of December 31, 2016 Quoted Prices Significant Significant (In Thousands) Series A Preferred Units $ (88,130 ) $ — $ — $ (88,130 ) Asset for foreign currency derivative contracts $ 57 $ — $ 57 $ — $ (88,073 ) During 2016, we recorded total impairment charges of $102.6 million , reflecting the decreased fair value for certain assets. Assets that were partially impaired included certain of our intangible assets. The fair values used in these impairment calculations were estimated based on discounted estimated future cash flows, which is based on significant unobservable inputs (Level 3) in accordance with the fair value hierarchy. A summary of these nonrecurring fair value measurements during the year ended December 31, 2016 , using the fair value hierarchy is as follows: Fair Value Measurements Using Quoted Prices Significant Significant Year-to-Date Description Total Fair Value (In Thousands) Tangible compressor assets $ — $ — $ — $ — $ 2,357 Identified intangible assets 20,600 (1) — — 20,600 7,866 Goodwill — — — — 92,402 Total $ 20,600 $ — $ — $ 20,600 $ 102,625 (1) Fair value as of March 31, 2016 date of impairment. Recently Issued Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09, "Revenue from Contracts with Customers." ASU 2014-09 supersedes the revenue recognition requirements in ASC 605, Revenue Recognition, and most industry-specific guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those years, under either full or modified retrospective adoption. During 2016, in preparation for the adoption of ASU No. 2014-09, we began a review of the various types of customer contract arrangements for our compression services, aftermarket services, and equipment sales operations. These reviews include 1) accumulating all customer contractual arrangements; 2) identifying individual performance obligations pursuant to each arrangement; 3) quantifying consideration under each arrangement; 4) allocating consideration among the identified performance obligations; and 5) determining the timing of revenue recognition pursuant to each arrangement. During 2017, we completed these contract reviews and have implemented revised accounting system processes in order to capture information required to be disclosed under ASU 2014-09. We will adopt this new guidance using the modified retrospective method on January 1, 2018. We have substantially completed our analysis of the new guidance and have not identified any material changes to the timing or amount of revenue to be recognized in future periods. The disclosures related to revenue recognition will be significantly expanded under ASU 2014-09, specifically around the quantitative and qualitative information about performance obligations, changes in contract assets and liabilities, and disaggregation of revenue. We continue to evaluate these requirements. In March 2016, the FASB issued ASU 2016-08,"Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)" to clarify the guidance on principal versus agent considerations. This ASU does not change the effective date or adoption method under ASU 2014-09 which is noted above. In April 2016, the FASB issued ASU 2016-10,"Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing" to clarify the guidance on identifying performance obligations and the licensing implementation guidance. This ASU does not change the effective date or adoption method under ASU 2014-09, which is noted above. Additionally, in May 2016, the FASB issued ASU 2016-12,"Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients". This ASU addresses and amends several aspects of ASU 2014-09, but does not change the core principle of the guidance. This ASU does not change the effective date or adoption method under ASU 2014-09 which is noted above. In July 2015, the FASB issued ASU No. 2015-11, “Simplifying the Measurement of Inventory”, which simplifies the subsequent measurement of inventory by requiring entities to measure inventory at the lower of cost or net realizable value, except for inventory measured using the last-in, first-out (LIFO) or the retail inventory methods. The ASU requires entities to compare the cost of inventory to one measure - net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The ASU is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, and is to be applied prospectively with early adoption permitted. As a result of the adoption of this standard during the first quarter of 2017, there was no material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" to increase comparability and transparency among different organizations. Organizations are required to recognize lease assets and lease liabilities in the balance sheet and disclose key information about the leasing arrangements and cash flows. The ASU is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods, with early adoption permitted, under a modified retrospective adoption. We are currently assessing the potential effects of these changes to our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" as part of a simplification initiative. The update addresses and simplifies several aspects of accounting for share-based payment transactions. The ASU is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted, and is to be applied using either modified retrospective, retrospective, or prospective transition method based on which amendment is being applied. Upon adoption of ASU 2016-09, we elected to change our accounting policy to account for forfeitures as they occur, using a modified retrospective method and determined that a cumulative-effect adjustment to retained earnings would be immaterial at transition during the first quarter of 2017. As a result of the adoption of this ASU, there was no impact on our consolidated financial statements. 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, which has an effective date of the first quarter of fiscal 2022, also applies to employee benefit plan accounting. We are currently assessing the potential effects of these changes to our consolidated financial statements and employee benefit plan accounting. In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments" to reduce diversity in practice in classification of certain transactions in the statement of cash flows. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted, under a retrospective transition adoption. We are currently assessing the potential effects of these changes to our consolidated financial statements. In November 2016, the FASB issued ASU 2016-16, "Intra-Entity Transfers of Assets Other Than Inventory" which requires companies to account for the income tax effects of intercompany transfers of assets other than inventory when the transfer occurs. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted, under a modified retrospective transition adoption. We are currently assessing the potential effects of these changes to our consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting" to clarify when to account for a change to the terms or conditions of a share-based payment award as a modification. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted. We do not expect the adoption of this standard to have a material impact on our

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 will terminate on the earlier of (i) a change of control of the General Partner or TETRA, or (ii) upon any party providing at least 180 days' prior written notice of termination. 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, 2017 , 2016 , and 2015 , we were charged by TETRA $37.2 million , $41.5 million , and $113.9 million , respectively, for expenses incurred on our behalf as described below. Amounts charged under the Omnibus Agreement and outstanding as of December 31, 2017 and 2016 are included in Amounts Payable to Affiliates in the accompanying consolidated balance sheets. In January 2017, our General Partner and TETRA agreed that $1.6 million of Amounts Payable to Affiliates as of December 31, 2016 that were charged to us by TETRA under the Omnibus Agreement would be paid with common units in lieu of cash, with the number of common units calculated based on the average trading price of our common units over a defined period. This amount represents certain corporate and general and administrative services for the fourth quarter of 2016. Pursuant to this agreement, 159,192 units were issued to TETRA in January 2017. In May 2017, our General Partner and TETRA entered into an agreement (the "First Quarter 2017 Omnibus Reimbursement Agreement") pursuant to which $1.7 million of Amounts Payable to Affiliates as of March 31, 2017 that were owed by us to TETRA under the Omnibus Agreement would be satisfied by newly issued common units instead of cash, with the number of common units calculated based on the average trading price of our common units, subject to limitations, over a defined period that began on May 12, 2017. This amount owed by us represented certain corporate and general and administrative services provided in the first quarter of 2017. Pursuant to the First Quarter 2017 Omnibus Reimbursement Agreement, 280,257 common units were issued to TETRA in June 2017. Under the terms of the Omnibus Agreement, we or TETRA may, but neither are under any obligation to, perform for the other such production enhancement or other oilfield services on a subcontract basis as are 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. Any such services are required to be performed on terms that are (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. Under the terms of the Omnibus Agreement, we or TETRA may, but are 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 is 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 be mutually agreed upon by TETRA and our General Partner. Any such sales, leases, or like-kind exchanges are required to be on terms that are (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. In addition, unless otherwise approved by the conflicts committee of our General Partner’s board of directors, TETRA may purchase newly fabricated equipment from us at a negotiated price, provided that such price may not be less than the sum of the total costs (other than any allocations of general and administrative expenses) incurred by us in fabricating such equipment plus a fixed margin percentage thereof, and TETRA may purchase from us previously fabricated equipment for a price that is 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 December 31, 2017 and 2016 is approximately 41% and 44% , respectively, with the common units held by the public representing an approximate 59% and 56% interest in us, respectively. As of December 31, 2017 , TETRA's ownership is through various wholly owned subsidiaries and consists of approximately 39% of the limited partner interests plus the approximately 2% general partner interest, through which it holds incentive distribution rights. As a result of its ownership of common units and its general partner interest in us, TETRA received distributions of $14.2 million , $22.3 million , and $30.5 million during the years ended December 31, 2017 , 2016 , and 2015 , respectively. In August 2016 and September 2016, we issued and sold 6,999,126 of the Preferred Units in a private placement. One of the purchasers in the Initial Private Placement was TETRA, which purchased 874,891 of the Preferred Units at the aggregate Issue Price of $10.0 million and representing 12.5% ownership of the Preferred Units. For further discussion, see Note E - Series A Convertible Preferred Units. 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.

The following discussion is not a complete description our long-term debt agreements or amendments and is qualified in its entirety by reference to the full text of the complete agreement and amendment, which are filed as an exhibit to our filings with the SEC. Bank Credit Facilities Under our credit agreement, as amended (the "Credit Agreement"), with a syndicate of banks including Bank of America, N.A. as administrative agent, we have an asset-based revolving credit facility with a borrowing capacity of up to $315 million , subject to certain requirements, which matures August 4, 2019. The Credit Agreement is available to provide our working capital needs, letters of credit, and for general partnership purposes, including capital expenditures and potential future expansions or acquisitions. The Credit Agreement provides that we can make distributions to holders of our common units, but only if there is no default or event of default under the facility and we maintain excess availability of $30.0 million under the Credit Agreement. Borrowings under the Credit Agreement bear interest at a rate per annum equal to, at our option, either (a) LIBOR (adjusted to reflect any required bank reserves) for an interest period equal to one, two, three, or six months (as selected by us), plus a leverage-based margin or (b) a base rate plus a leverage-based margin; such base rate shall be determined by reference to the highest of (1) the prime rate of interest per annum announced from time to time by Bank of America, N.A., (2) the Federal Funds rate plus 0.50% per annum, and (3) LIBOR (adjusted to reflect any required bank reserves) for a one month interest period on such day plus 1.00% per annum. In addition to paying interest on outstanding principal under the Credit Agreement, we are required to pay a commitment fee in respect of the unutilized commitments. We are also required to pay a customary letter of credit fee equal to the applicable margin on revolving credit LIBOR loans, fronting fees, and other fees, agreed to with the administrative agent and lenders. As of December 31, 2017 , we had a balance outstanding of $228.0 million , had approximately $7.2 million letters of credit, and had availability under the Credit Agreement of approximately $79.8 million . Under our Credit Agreement, we and our subsidiary CSI Compressco Sub Inc. are named as the borrowers, and all obligations under the Credit Agreement are guaranteed by all of our existing and future, direct and indirect, domestic restricted subsidiaries (other than domestic subsidiaries that are wholly owned by foreign subsidiaries). The Credit Agreement includes customary covenants that, among other things, limit our ability to incur additional debt, incur, or permit certain liens to exist, or make certain loans, investments, acquisitions, or other restricted payments. Our Credit Agreement includes a maximum credit commitment and included within the maximum amount is availability for letters of credit (with a sublimit of $20.0 million) and swingline loans (with a sublimit of $60.0 million). The amount of outstanding borrowings under the Credit Agreement is subject to certain limitations, including a borrowing-base calculation as described below and borrowing limitations as a result of financial covenants. On May 25, 2016, we entered into an amendment (the "Third Amendment") to our Credit Agreement that, among other things, modified certain financial covenants in the Credit Agreement. As discussed below, these financial covenants were further amended in November 2016. In addition, the Third Amendment provided for other changes related to the Credit Agreement including, among other amendments (i) reducing the maximum aggregate lender commitments from $400.0 million to $340.0 million, (ii) increasing the applicable margin by 0.25% with a range between 2.00% and 3.00% per annum for LIBOR-based loans and 1.00% to 2.00% per annum for base-rate loans, based on the applicable consolidated total leverage ratio, and (iii) imposing a requirement that we use designated consolidated cash and cash equivalent balances in excess of $35.0 million to prepay the loans as well as other provisions and restrictions. As a result of the reduction of the maximum lender commitment pursuant to the Third Amendment, unamortized deferred finance costs of $0.7 million were charged to interest expense during the year ended December 31, 2016. Pursuant to the Third Amendment, bank fees of $0.7 million were incurred during the year ended December 31, 2016 and were deferred, netting against the carrying value of the amount outstanding under our Credit Agreement. On November 3, 2016 , we entered into an additional amendment (the "Fourth Amendment") to our Credit Agreement that, among other changes, further modified certain financial covenants in the Credit Agreement. The Fourth Amendment converted the Credit Agreement from a secured revolving credit facility into an asset-based revolving credit facility ("ABL Facility"). Borrowings under the Credit Agreement, as amended, may not exceed a borrowing base equal to the sum of (i) 80% of the aggregate net amount of our eligible accounts receivable, plus (ii) 20% of the aggregate value of any eligible parts inventory, in the event we elect to include eligible parts inventory pursuant to a notice to the administrative agent, plus (iii) 80% of the net in-place eligible compressor equipment, decreased each month by the amount of associated depreciation expense, plus (iv) 80% of the cost of new eligible compressor equipment, and minus (v) the amount of any reserves established by the administrative agent in its discretion. In addition, the Fourth Amendment imposed other requirements, including requirements related to borrowing base reporting on a monthly basis and provisions to permit periodic appraisal and inspection of collateral assets. Pursuant to the Fourth Amendment, certain additional restrictive provisions ("cash dominion provisions") are imposed if an event of default has occurred and is continuing or excess availability under the ABL Facility falls below $30.0 million. In addition, the Fourth Amendment reduced the maximum aggregate lender commitments from $340.0 million to $315.0 million. As a result of the further reduction of the aggregate lender commitments pursuant to the Fourth Amendment, unamortized deferred finance costs of $0.3 million were charged to interest expense during the year ended December 31, 2016. Pursuant to the Fourth Amendment, associated fees of $0.8 million were incurred during the year ended December 31, 2016 and were deferred, netting against the carrying value of the amount outstanding under the Credit Agreement. On May 5, 2017, we entered into an amendment (the "Fifth Amendment") to our Credit Agreement that modified certain financial covenants in the Credit Agreement, providing that (i) the consolidated total leverage ratio may not exceed (a) 5.95 to 1 as of March 31, 2017; (b) 6.75 to 1 as of June 30, 2017 and September 30, 2017; (c) 6.50 to 1 as of December 31, 2017 and March 31, 2018; (d) 6.25 to 1 as of June 30, 2018 and September 30, 2018; (e) 6.00 to 1 as of December 31, 2018; and (e) 5.75 to 1 as of March 31, 2019 and thereafter; and (ii) the consolidated secured leverage ratio may not exceed 3.25 to 1 as of the end of any fiscal quarter. The consolidated interest coverage ratio was not amended by the Fifth Amendment. In addition, the Fifth Amendment (i) increased the applicable margin by 0.25% in the event the consolidated total leverage ratio exceeds 6.00 to 1, resulting in a range for the applicable margin between 2.00% and 3.50% per annum for LIBOR-based loans and 1.00 to 2.50% per annum for base-rate loans, according to the consolidated total leverage ratio, and (ii) modified the appraisal delivery requirement from an annual requirement to a semi-annual requirement. In connection with the Fifth Amendment, the board of directors of our General Partner adopted resolutions limiting the cash distributions payable on our common units to no more than $0.1875 per common unit for the quarterly period ended June 30, 2017. The Fifth Amendment also included additional revisions that provide flexibility for the issuance of preferred securities. The weighted average interest rate on borrowings outstanding under the Credit Agreement as of December 31, 2017 was 5.0% per annum. At December 31, 2017 , our consolidated total leverage ratio was 6.48 to 1 (compared to 6.50 to 1 maximum as required under the Credit Agreement), our consolidated secured leverage ratio was 2.89 to 1 (compared to 3.25 to 1 maximum as required under the Credit Agreement) and our consolidated interest coverage ratio was 2.55 to 1 (compared to a 2.25 to 1 minimum as required under the Credit Agreement). The consolidated total leverage ratio and the consolidated secured leverage ratio, as both are calculated under the Credit Agreement, exclude the long-term liability for the Preferred Units in the determination of total indebtedness. We are in compliance with all covenants of the Credit Agreement as of December 31, 2017 . We have reviewed our financial forecasts as of March 1, 2018 for the subsequent twelve month period, which considers the current level of distributions to be paid on our common units. We believe that we will have adequate liquidity, earnings, and operating cash flows to fund our operations and debt obligations and maintain compliance with the covenants under our debt agreements through March 1, 2019. 7.25% Senior Notes The obligations under the 7.25% Senior Notes due 2022 (the "7.25% Senior Notes") are jointly and severally, and fully and unconditionally, guaranteed on a senior unsecured basis by each of our domestic restricted subsidiaries (other than CSI Compressco Finance) that guarantee our other indebtedness (the "Guarantors" and together with the Issuers, the "Obligors"). The 7.25% Senior Notes and the subsidiary guarantees thereof (together, the "Securities") were issued pursuant to an indenture described below. As of December 31, 2017 , 295.9 million in aggregate principal amount of the 7.25% Senior Notes are outstanding. The Obligors issued the Securities pursuant to the Indenture dated as of August 4, 2014 (the "Indenture") by and among the Obligors and U.S. Bank National Association, as trustee (the "Trustee"). The 7.25% Senior Notes accrue interest at a rate of 7.25% per annum. Interest on the 7.25% Senior Notes is payable semi-annually in arrears on February 15 and August 15 of each year. The 7.25% Senior Notes are scheduled to mature on August 15, 2022. The Indenture contains customary covenants restricting our ability and the ability of our restricted subsidiaries to: (i) pay dividends and make certain distributions, investments and other restricted payments; (ii) incur additional indebtedness or issue certain preferred shares; (iii) create certain liens; (iv) sell assets; (v) merge, consolidate, sell or otherwise dispose of all or substantially all of our assets; (vi) enter into transactions with affiliates; and (vii) designate our subsidiaries as unrestricted subsidiaries under the Indenture. The Indenture also contains customary events of default and acceleration provisions relating to such events of default, which provide that upon an event of default under the Indenture, the Trustee or the holders of at least 25% in aggregate principal amount of the 7.25% Senior Notes then outstanding may declare all amounts owing under the 7.25% Senior Notes to be due and payable. During September 2016 and October 2016, we repurchased on the open market and retired $54.1 million aggregate principal amount of 7.25% Senior Notes for a purchase price of $50.9 million , at an average repurchase price of 94% of the principal amount of the 7.25% Senior Notes, plus accrued interest, utilizing a portion of the net proceeds of the sale of the Preferred Units. Following the repurchase of these 7.25% Senior Notes, $295.9 million aggregate principal amount of 7.25% Senior Notes remain outstanding. In connection with the repurchase of these 7.25% Senior Notes, $1.4 million of early extinguishment net gain was credited to other expense during the year ended December 31, 2016, representing the difference between the repurchase price and the $54.1 million aggregate principal amount of the 7.25% Senior Notes repurchased, and $1.8 million of remaining unamortized deferred finance costs and discounts associated with the repurchased 7.25% Senior Notes.

Series A Preferred Units [Abstract] [Abstract]
Series A Convertible Preferred Units	SERIES A CONVERTIBLE PREFERRED UNITS On August 8, 2016 and September 20, 2016 , we entered into Series A Preferred Unit Purchase Agreements (the “Unit Purchase Agreements”) with certain purchasers to issue and sell in private placements (the "Initial Private Placement" and "Subsequent Private Placement," respectively) an aggregate of 6,999,126 Preferred Units for a cash purchase price of $11.43 per Preferred Unit (the “Issue Price”), resulting in total 2016 net proceeds, after deducting certain offering expenses, of approximately $77.3 million . One of the purchasers in the Initial Private Placement was TETRA, which purchased 874,891 of the Preferred Units at the aggregate Issue Price of $10.0 million . The holders of Preferred Units (each, a “Preferred Unitholder”) receive quarterly distributions, which are paid in kind in additional Preferred Units, equal to an annual rate of 11.00% of the Issue Price (or $1.2573 per Preferred Unit annualized), subject to certain adjustments. The rights of the Preferred Units include certain anti-dilution adjustments, including adjustments for economic dilution resulting from the issuance of common units in the future below a set price. A ratable portion of the Preferred Units have been, and will continue to be converted into common units on the eighth day of each month over a period of thirty months that began in March 2017 (each, a “Conversion Date”), subject to certain provisions of the Amended and Restated Partnership Agreement that may delay or accelerate all or a portion of such monthly conversions. On each Conversion Date, a portion of the Preferred Units will convert into common units representing limited partner interests in the Partnership in an amount equal to, with respect to each Preferred Unitholder, the number of Preferred Units held by such Preferred Unitholder divided by the number of Conversion Dates remaining, subject to adjustment described in the Amended and Restated Partnership Agreement, with the conversion price (the "Conversion Price") determined by the trading prices of the common units over the prior month, among other factors, and as otherwise impacted by the existence of certain conditions related to the common units. On June 7, 2017, as permitted under the Amended and Restated Partnership Agreement, we elected to defer the monthly conversion of Preferred Units for each of the Conversion Dates during the three month period beginning July 2017. As a result, no Preferred Units were converted into common units during the three month period ended September 30, 2017, and future monthly conversions were increased beginning in October 2017. Based on the number of Preferred Units outstanding as of December 31, 2017 , 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 34.1 million common units; however, the Partnership may, at its option, pay cash, or a combination of cash and common units, to the Preferred Unitholders instead of issuing common units on any Conversion Date, subject to certain restrictions as described in the Amended and Restated Partnership Agreement and the Credit Agreement. The total number of Preferred Units outstanding as of December 31, 2017 was 5,975,200 . Because the Preferred Units may be settled using a variable number of common units, the fair value of the Preferred Units is classified as a long-term liability on our consolidated balance sheet in accordance with ASC 480 "Distinguishing Liabilities and Equity." The fair value of the Preferred Units as of December 31, 2017 was $70.3 million . Changes in the fair value during each quarterly period, including the $(3.4) million and $5.0 million net (decrease) increase in fair value during the years ended 2017 and 2016 , respectively, are charged or credited to earnings in the accompanying consolidated statements of operations. Based on the conversion provisions of the Preferred Units, and using the Conversion Price calculated as of December 31, 2017 , the theoretical number of common units that would be issued if all of the outstanding Preferred Units were converted on December 31, 2017 on the same basis as the monthly conversions would be approximately 14.6 million common units, with an aggregate market value of $79.9 million . A $1 decrease in the Conversion Price would result in the issuance of approximately 3.8 million additional common units pursuant to these conversion provisions.

Leases	LEASES We lease some of our office space, warehouse space, operating locations, and machinery and equipment. The office, warehouse, and operating location leases, which vary from one to five year terms that expire at various dates through 2021 and are renewable for three and five year periods on similar terms, are classified as operating leases and generally require us to pay all maintenance and insurance costs. Future minimum lease payments by year and in the aggregate, under leases with terms of one year or more, consist of the following at December 31, 2017 : Operating Leases (In Thousands) 2018 $ 2,567 2019 1,450 2020 1,169 2021 821 2022 18 After 2020 — Total minimum lease payments $ 6,025 Rental expense for all operating leases was $5.6 million , $7.2 million , and $9.2 million in 2017 , 2016 , and 2015 , respectively.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES On December 22, 2017, the United States enacted significant changes to the U.S. tax law following the passage and signing of H.R.1, “An Act to Provide the Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018” (the “Act”) (previously known as “The Tax Cuts and Jobs Act”). Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. We have calculated our best estimate of the impact of the Act in our year-end income tax provision in accordance with our understanding of the Act and guidance available as of the date of this filing and as result have recorded income tax expense of $21.9 million in the fourth quarter of 2017, the period in which the legislation was enacted. This income tax expense was fully offset by a decrease in the valuation allowance previously recorded on our net deferred tax assets. As such, the Act resulted in no net tax expense. The provisional amount related to the remeasurement of certain deferred tax assets and liabilities, based on the rates at which they are expected to reverse in the future was $21.9 million , offset by a corresponding decrease in our valuation allowance. The provisional amount related to the one-time transition tax was zero . On December 22, 2017, Staff Accounting Bulletin 118 (“SAB 118”) was issued to address the application of US GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Act. We have made reasonable estimates of the effects and recorded provisional amounts in our financial statement as of December 31, 2017. However, we are still analyzing certain aspects of the Act and refining our calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. We have not yet completed our calculation of the total post-1986 E&P for these foreign subsidiaries. Further, the transition tax is based in part on the amount of those earnings held in cash and other specified assets. This amount may change when we finalize the calculation of post-1986 foreign E&P previously deferred from US federal taxation and finalize the amounts held in cash or other specified assets. In January 2018, the FASB released guidance on the accounting for tax on the global intangible low-taxed income ("GILTI") provisions of the 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 cost are both acceptable methods subject to an accounting policy election. A provisional estimate could not be made as we have not yet completed our assessment or elected an accounting policy to either recognize deferred taxes for basis differences expected to reverse as GILTI or to record GILTI as period costs if and when incurred. 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. 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 the Partnership is responsible for income taxes in these countries. The income tax provision (benefit) attributable to our operations for the years ended December 31, 2017 , 2016 , and 2015 consists of the following: Year Ended December 31, 2017 2016 2015 (In Thousands) Current Federal $ (47 ) $ — $ (1,632 ) State 688 836 1,330 Foreign 1,386 999 806 2,027 1,835 504 Deferred Federal — — (847 ) State 19 (8 ) (354 ) Foreign 738 38 596 757 30 (605 ) Total tax provision (benefit) $ 2,784 $ 1,865 $ (101 ) A reconciliation of the provision (benefit) for income taxes, computed by applying the federal statutory rate to income before income taxes and the reported income taxes, is as follows: Year Ended December 31, 2017 2016 2015 (In Thousands) Income (loss) tax provision computed at statutory federal income tax rates $ (12,809 ) $ (46,332 ) $ (49,888 ) Partnership (earnings) losses 12,809 46,332 49,888 Corporate subsidiary earnings (loss) subject to federal tax 5,805 (33,791 ) (36,712 ) Impact of goodwill impairments — 2,134 3,341 Impact of U.S. tax law change 21,928 — — Valuation allowances (28,236 ) 33,056 33,682 Income tax expense attributable to foreign earnings 2,565 1,297 92 State income taxes (net of federal benefit) 734 (849 ) (619 ) Nondeductible expenses 36 23 79 Other (48 ) (5 ) 36 Total tax provision (benefit) $ 2,784 $ 1,865 $ (101 ) Corporate subsidiary earnings (loss) subject to federal tax for 2017 includes $11.1 million related to a cumulative correcting cost allocation adjustment between U.S. subsidiary entities from prior years, the net impact from which is considered immaterial. Income (loss) before income tax provision includes the following components: Year Ended December 31, 2017 2016 2015 (In Thousands) Domestic $ (40,649 ) $ (146,007 ) $ (150,814 ) International 2,974 9,734 4,083 Total $ (37,675 ) $ (136,273 ) $ (146,731 ) 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 2010. 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 2012 Non-U.S. jurisdictions 2011 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: Deferred Tax Assets December 31, 2017 2016 (In Thousands) Inventory reserve $ 270 $ 690 Amortization for book in excess of tax expense 27,721 46,487 Accruals 264 452 Net operating losses 17,809 33,300 Bad debt reserve 144 472 Other 42 84 Total deferred tax assets 46,250 81,485 Valuation allowance (39,367 ) (69,176 ) Net deferred tax assets $ 6,883 $ 12,309 Deferred Tax Liabilities December 31, 2017 2016 (In Thousands) Accruals $ 1,076 $ 269 Depreciation for tax in excess of book expense 7,011 11,892 All other 190 838 Total deferred tax liability 8,277 12,999 Net deferred tax liability $ 1,394 $ 690 At December 31, 2017 , we have federal, state, and foreign net operating loss carryforwards/carrybacks equal to approximately $15.4 million , $1.5 million , and $0.9 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 2019 to 2036. 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 decrease in the valuation allowance during the year ended December 31, 2017 was $29.8 million . The change in the valuation allowance during 2017 primarily relates to the decrease in the federal statutory income tax rate from 35% to 21% . The increases in the valuation allowance during the years ended December 31, 2016 and 2015 were $33.0 million and $34.1 million , respectively. The change in the valuation allowance during 2016 primarily relates to deferred tax assets associated with losses generated in our U.S. corporate subsidiaries and certain foreign jurisdictions. 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 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, 2017 and 2016 , 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.

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 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, 2017 , we granted to certain officers and employees an aggregate of 290,190 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 $8.40 per unit, or an aggregate market value of $2.4 million . During the year ended December 31, 2016 , we granted to certain officers and employees 396,692 phantom 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 $8.38 per unit, or an aggregate market value of $3.3 million . During the year ended December 31, 2015 , we granted to certain officers and employees 180,136 restricted common unit awards, having an average market value (equal to the closing price of the common units on the dates of grant) of $20.35 per unit, or an aggregate market value of $3.9 million . The fair value of awards vesting during 2017 , 2016 , and 2015 was approximately $2.8 million , $1.5 million , and $1.1 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, 2017 : Units Weighted Average Grant Date Fair Value Per Unit (In Thousands) Nonvested units outstanding at December 31, 2016 (1) 609 $ 13.41 Units granted 290 8.40 Exercised/released (173 ) 16.11 Cancelled/forfeited (257 ) 13.17 Nonvested units outstanding at December 31, 2017 (2) 469 $ 9.31 (1) This number excludes 289,830 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 176,159 performance-based phantom units, which, when combined with the 18,226 granted, (net of 2017 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 352,318 . Total estimated unrecognized equity-based compensation expense from unvested units as of December 31, 2017 , was approximately $2.2 million and is expected to be recognized over a weighted average period of approximately 1.7 years. The amount recognized in 2017 , 2016 , and 2015 was approximately $1.2 million , $3.0 million , and $2.2 million , respectively, and included in selling, general, and administrative expense.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Market Risks and Derivative Contracts	MARKET RISKS AND DERIVATIVE CONTRACTS We are exposed to financial and market risks that affect our businesses. 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. As a result of our variable rate bank credit facility, we face market risk exposure related to changes in applicable interest rates. We have concentrations of credit risk as a result of trade receivables owed to us by companies in the energy industry. Our financial risk management activities may at times involve, among other measures, the use of derivative financial instruments, such as swap and collar agreements, to hedge the impact of market price risk exposures. Foreign Currency Derivative Contracts 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, 2017 and 2016 , we had the following foreign currency derivative contracts outstanding relating to a portion of our foreign operations: December 31, 2017 US Dollar Notional Amount Traded Exchange Rate Settlement Date (In Thousands) Forward sale Mexican peso $ 6,067 19.28 1/18/2018 December 31, 2016 US Dollar Notional Amount Traded Exchange Rate Settlement Date (In Thousands) Forward sale Mexican peso $ 2,483 20.18 1/18/2017 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 as reported to us by our counterparty (a Level 2 fair value measurement). The fair value of our foreign currency derivative instruments as of December 31, 2017 and 2016 , are as follows: Balance Sheet Fair Value at Fair Value at Foreign currency derivative instruments Location December 31, 2017 December 31, 2016 (In Thousands) Forward sale contracts Current assets $ 130 57 Forward sale contracts Current liabilities (10 ) — Total $ 120 57 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, 2017 , 2016 , and 2015 , we recognized approximately $(38,000) , $378,000 , and $514,000 of net gains (losses), respectively, associated with our foreign currency derivative program, and such amount is included in other expense, net in the accompanying consolidated statement of operations.

Earnings Per Common and Subordi

Earnings Per Common and Subordinated Unit	12 Months Ended

Earnings Per Share [Abstract]
Earnings Per Common and Subordinated Unit	EARNINGS PER COMMON AND SUBORDINATED UNIT The computations of earnings per common are based on the weighted average number of common outstanding during the applicable full-year period. Basic earnings per common 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 during the period. When computing earnings per common under the two-class method in periods when distributions are greater than earnings, the amount of the distributions is deducted from net income 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 a reconciliation of the weighted average number of common units outstanding to the number of common units used in the computations of net income per common unit. Year Ended December 31, 2017 2016 2015 Common Units Common Units Common Number of weighted average units outstanding 35,035,428 33,262,376 33,169,413 Unit awards outstanding — — — Average diluted units outstanding 35,035,428 33,262,376 33,169,413 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, 2017 , 2016 , and 2015 approximately 90,594 , 9,707 , and 29,372 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 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 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 is 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, 2017 and 2016.

Segments [Abstract]
Segments	SEGMENTS ASC 280-10-50, “Operating Segments”, 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, net income, and EBITDA are not captured or analyzed by these items. 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.

Summary of Significant Accoun26

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017	Dec. 31, 2016
Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 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. The impact of such reclassifications was not significant to the prior year's overall presentation.
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 The fair values of our financial instruments, which may include cash, accounts receivable, amounts outstanding under our variable rate bank credit facility, accounts payable and accrued liabilities, approximate their carrying amounts. 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. As a result of the outstanding balances under our variable rate revolving credit facility, we face market risk exposure related to changes in applicable interest rates. Although we have no interest rate swap contracts outstanding to hedge this potential risk exposure, we have entered into certain fixed interest rate notes, which are scheduled to mature in 2022 and which mitigate this risk on our total outstanding borrowings. Significant Customers During 2017 and 2016, ConocoPhillips accounted for approximately 11.0% of our revenues. During 2015 , no individual customer accounted for 10% or more of our revenues.
Foreign currencies policy	Foreign Currencies We have designated the Canadian dollar and Argentine peso as the functional currencies for our operations in Canada and Argentina, respectively. 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 and (losses) are included in other expense and totaled $48,000 , $(1.6) million , and $(2.0) million during the years ended December 31, 2017 , 2016 , and 2015 , respectively.
Allowances for doubtful accounts policy	Allowances for Doubtful Accounts Allowances for doubtful accounts are determined on a specific identification basis when we believe that the collection of specific amounts owed to us is not probable. The changes in allowances for doubtful accounts are as follows: Year Ended December 31, 2017 2016 2015 (In Thousands) At beginning of period $ 2,253 $ 1,973 $ 1,496 Activity in the period: Provision for doubtful accounts 968 1,704 508 Account (chargeoffs) recoveries, net (2,399 ) (1,424 ) (31 ) At end of period $ 822 $ 2,253 $ 1,973
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 market 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. Work in progress inventories consist primarily of new compressor packages located at our fabrication facility in Midland, Texas. We write down the value of inventory by an amount equal to the difference between its cost and its estimated market value. Components of inventories as of December 31, 2017 , and December 31, 2016 , are as follows: December 31, 2017 December 31, 2016 (In Thousands) Parts and supplies $ 31,703 $ 25,932 Work in progress 10,580 5,510 Total inventories $ 42,283 $ 31,442
Compression and related services revenues and costs policy	Compression and Related Services Revenues and Costs Our compression and related services revenues include revenues from our U.S. corporate subsidiaries' operating lease agreements with customers. For the three years in the period ended December 31, 2017 , the following operating lease revenues and associated costs were included in compression and related service revenues and cost of compression and related services, respectively, in the accompanying consolidated statements of operations. As a result of our customers entering into compression service contracts, our revenues from rental contracts have decreased during the year ended December 31, 2017 compared to the prior years. Year Ended December 31, 2017 2016 2015 (In Thousands) Rental revenue $ 38,720 $ 42,644 $ 117,540 Rental expenses $ 17,560 $ 25,039 $ 66,040
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, 2017 , 2016 , and 2015 was $66.0 million , $68.8 million , and $71.7 million , respectively.
Intangible assets other than goodwill policy	Intangible Assets other than Goodwill Trademarks/trade names, customer relationships, and other intangible assets are recorded on the basis of cost and 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 $3.2 million , $3.4 million , and $6.8 million for the years ended December 31, 2017 , 2016 , and 2015 , respectively, 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 for 2018 , $2.9 million for 2019 , $2.9 million for 2020 , $2.9 million for 2021 , and $2.9 million for 2022 . 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. See "Impairments of Long-Lived Assets" section below.
Goodwill policy	Goodwill Goodwill represents the excess of cost over the fair value of the net assets of businesses acquired in purchase transactions. Prior to the impairment of remaining goodwill as of March 31, 2016, we performed a goodwill impairment test on an annual basis or whenever indicators of impairment were present. We performed the annual test of goodwill impairment following the fourth quarter of each year. The assessment for goodwill impairment begins with a qualitative assessment of whether it is “more likely than not” that the fair value of our business is less than its carrying value. This qualitative assessment requires the evaluation, based on the weight of evidence, of the significance of all identified events and circumstances. During 2015, and continuing into 2016, global oil and natural gas commodity prices, particularly crude oil, were significantly reduced. These low commodity prices had a negative impact on industry drilling and capital expenditure activity, which affected the demand for a portion of our products and services. The accompanying decrease in the price of our common units during the last half of 2015 and early 2016 also resulted in an overall reduction in our market capitalization. Based on this qualitative assessment, we determined that, due to the decline in the price of our common units that resulted in our market capitalization being less than the book value of our consolidated partners' capital balance as of December 31, 2015 and March 31, 2016, it was “more likely than not” that the fair value of our business was less than its carrying value as of these dates. When the qualitative analysis indicates that it is “more likely than not” that our business’ fair value is less than its carrying value, the resulting goodwill impairment test consists of a two-step accounting test being performed. The first step of the impairment test is to compare the estimated fair value with the recorded net book value (including goodwill) of our business. If the estimated fair value is higher than the recorded net book value, no impairment is deemed to exist and no further testing is required. If, however, the estimated fair value is below the recorded net book value, an impairment loss is calculated by comparing the recorded net book value of goodwill to our estimated implied fair value of that goodwill. Our estimates of our fair value, when required, are based on a combination of an income and market approach. These estimates are imprecise and are subject to our estimates of our future cash flows and our judgment as to how these estimated cash flows translate into our estimated fair value. These estimates and judgments are affected by numerous factors, including the general economic environment at the time of our assessment, which affects our overall market capitalization. Our management must apply judgment in determining the estimated fair value for purposes of performing the goodwill impairment test. Management uses all available information to make these fair value determinations, including the present value of expected future cash flows using discount rates commensurate with the risks involved in the assets. The resultant fair values calculated are then compared to observable metrics for other companies in our industry or on mergers and acquisitions in our industry, to determine whether those valuations, in our judgment, appear reasonable. The accounting principles regarding goodwill acknowledge that the observed market prices of individual trades of a company’s stock (and thus its computed market capitalization) may not be representative of the fair value of the company as a whole. Substantial value may arise from the ability to take advantage of synergies and other benefits that flow from control over another entity. Consequently, measuring the fair value of a collection of assets and liabilities that operate together in a controlled entity is different from measuring the fair value of a single share of that entity’s common stock. Therefore, once the fair value of the reporting units was determined, we also added a control premium to the calculations. This control premium is judgmental and is based on observed mergers and acquisitions in our industry. As part of our internal annual business outlook that we performed during 2015 and 2016, we considered changes in the global economic environment that affected our common unit price and market capitalization. As a result of the annual goodwill impairment test process described above, we recorded impairments of goodwill of $92.3 million as of December 31, 2015 and $92.4 million as of March 31, 2016 . As of December 31, 2015, as a result of decreased demand for our products and services due to decreased oil and natural gas commodity prices, and due to decrease in the price of our common units, we determined that it was "more likely than not" that our fair value was less than our net book value as of December 31, 2015. With regard to the 2016 impairment, due to the decrease in the price of our common units during the first three months of 2016, our market capitalizations as of March 31, 2016, was again below our recorded net book value, including remaining goodwill. In addition, the continuing low oil and natural gas commodity price environment resulted in a further negative impact on demand for the products and services for each of our reporting units. As a result of these factors, we determined that it was “more likely than not” that our fair value was less than our net book value as of March 31, 2016. As of December 31, 2017 , the carrying amount of goodwill is $0.0 million , after giving effect to the $233.5 million of accumulated impairment losses. The changes in the carrying amount of goodwill are as follows: Year Ended December 31, 2017 2016 2015 (In Thousands) Balance, beginning of year $ — $ 92,402 $ 233,548 Goodwill acquired during the year — — — Goodwill adjustments — (92,402 ) (141,146 ) Balance, end of year $ — $ — $ 92,402
Impairment of long-lived assets policy		Impairments of Long-Lived Assets 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 the first quarter of 2016, as a result of continuing decreased demand as a result of current market conditions, we recorded impairments of approximately $7.9 million associated with certain identified intangible assets. During the fourth quarter of 2016, as a result of fire damage to compressor packages, we recorded impairments of approximately $2.4 million associated with certain identified compressor units. This amount was charged to Long-Lived Asset Impairment expense in the accompanying consolidated statement of operations.
Revenue recognition policy		Revenue Recognition We recognize revenue using the following criteria: (a) persuasive evidence of an exchange arrangement exists; (b) delivery has occurred or services have been rendered; (c) the buyer’s price is fixed or determinable; and (d) collectability is reasonably assured. 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. Collections associated with progressive billings to customers for the construction of compression equipment is included in unearned income in the consolidated balance sheets.
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 of the United States 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. Beginning in 2015, a portion of the carrying value of certain deferred tax assets is subjected to a valuation allowance. See Note G - Income Taxes for further discussion.
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 United States 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 accumulated other comprehensive income (loss) during the three years ended December 31, 2017 , December 31, 2016 , and December 31, 2015 is as follows: Year Ended December 31, 2017 2016 2015 (In Thousands) Balance, beginning of year $ (10,411 ) $ (8,393 ) $ (3,336 ) Foreign currency translation adjustment, net of tax of $0 in 2017, 2016, and 2015 (1,078 ) (2,018 ) (5,057 ) Balance, end of year $ (11,489 ) $ (10,411 ) $ (8,393 ) Activity within accumulated other comprehensive income includes no reclassifications to net income.
Allocation of net income policy	Allocation of Net Income Our net income is allocated to partners’ capital accounts in accordance with the provisions of the Partnership Agreement.
Fair value measurements policy	Fair Value Measurements Fair 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. generally accepted accounting principles ("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. We utilize fair value measurements to account for certain items and account balances within our consolidated financial statements. Fair value measurements are utilized in the determination of the carrying value of our Preferred Units (a Level 3 fair value measurement), which were issued in August and September 2016. 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 as determined by our counterparty financial institution (a level 2 fair value measurement). 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 and goodwill (a Level 3 fair value measurement), and for the impairment of long-lived assets, including goodwill (a level 3 fair value measurement). The fair value of certain of our financial instruments, which may include cash, accounts receivable, short-term borrowings, and variable-rate long-term debt pursuant to our bank credit agreement, approximate their carrying amounts. The fair values of our publicly traded long-term 7.25% Senior Notes at December 31, 2017 and December 31, 2016 , were approximately $279.7 million and $278.2 million (a level 2 fair value measurement). Those fair values compared to an aggregate principal amount of such notes at December 31, 2017 and 2016 of $295.9 million . 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. The fair valuation of our Preferred Units liability is increased by, among other factors, projected increases in our common unit price, and by increases in the volatility and decreases in the debt yields of comparable peer companies. Increases (or decreases) in the fair value of our Preferred Units will increase (decrease) the associated liability and result in future adjustments to earnings for the associated valuation losses (gains). A summary of these recurring fair value measurements as of December 31, 2017 and 2016 , is as follows: Fair Value Measurements Using Description Total as of December 31, 2017 Quoted Prices Significant Significant (In Thousands) Series A Preferred Units $ (70,260 ) $ — $ — $ (70,260 ) Asset for foreign currency derivative contracts 130 — 130 — Liability for foreign currency derivative contracts (10 ) — (10 ) — $ (70,140 ) Fair Value Measurements Using Description Total as of December 31, 2016 Quoted Prices Significant Significant (In Thousands) Series A Preferred Units $ (88,130 ) $ — $ — $ (88,130 ) Asset for foreign currency derivative contracts $ 57 $ — $ 57 $ — $ (88,073 ) During 2016, we recorded total impairment charges of $102.6 million , reflecting the decreased fair value for certain assets. Assets that were partially impaired included certain of our intangible assets. The fair values used in these impairment calculations were estimated based on discounted estimated future cash flows, which is based on significant unobservable inputs (Level 3) in accordance with the fair value hierarchy. A summary of these nonrecurring fair value measurements during the year ended December 31, 2016 , using the fair value hierarchy is as follows: Fair Value Measurements Using Quoted Prices Significant Significant Year-to-Date Description Total Fair Value (In Thousands) Tangible compressor assets $ — $ — $ — $ — $ 2,357 Identified intangible assets 20,600 (1) — — 20,600 7,866 Goodwill — — — — 92,402 Total $ 20,600 $ — $ — $ 20,600 $ 102,625
Recently issued accounting pronouncements policy	Recently Issued Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09, "Revenue from Contracts with Customers." ASU 2014-09 supersedes the revenue recognition requirements in ASC 605, Revenue Recognition, and most industry-specific guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those years, under either full or modified retrospective adoption. During 2016, in preparation for the adoption of ASU No. 2014-09, we began a review of the various types of customer contract arrangements for our compression services, aftermarket services, and equipment sales operations. These reviews include 1) accumulating all customer contractual arrangements; 2) identifying individual performance obligations pursuant to each arrangement; 3) quantifying consideration under each arrangement; 4) allocating consideration among the identified performance obligations; and 5) determining the timing of revenue recognition pursuant to each arrangement. During 2017, we completed these contract reviews and have implemented revised accounting system processes in order to capture information required to be disclosed under ASU 2014-09. We will adopt this new guidance using the modified retrospective method on January 1, 2018. We have substantially completed our analysis of the new guidance and have not identified any material changes to the timing or amount of revenue to be recognized in future periods. The disclosures related to revenue recognition will be significantly expanded under ASU 2014-09, specifically around the quantitative and qualitative information about performance obligations, changes in contract assets and liabilities, and disaggregation of revenue. We continue to evaluate these requirements. In March 2016, the FASB issued ASU 2016-08,"Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)" to clarify the guidance on principal versus agent considerations. This ASU does not change the effective date or adoption method under ASU 2014-09 which is noted above. In April 2016, the FASB issued ASU 2016-10,"Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing" to clarify the guidance on identifying performance obligations and the licensing implementation guidance. This ASU does not change the effective date or adoption method under ASU 2014-09, which is noted above. Additionally, in May 2016, the FASB issued ASU 2016-12,"Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients". This ASU addresses and amends several aspects of ASU 2014-09, but does not change the core principle of the guidance. This ASU does not change the effective date or adoption method under ASU 2014-09 which is noted above. In July 2015, the FASB issued ASU No. 2015-11, “Simplifying the Measurement of Inventory”, which simplifies the subsequent measurement of inventory by requiring entities to measure inventory at the lower of cost or net realizable value, except for inventory measured using the last-in, first-out (LIFO) or the retail inventory methods. The ASU requires entities to compare the cost of inventory to one measure - net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The ASU is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, and is to be applied prospectively with early adoption permitted. As a result of the adoption of this standard during the first quarter of 2017, there was no material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" to increase comparability and transparency among different organizations. Organizations are required to recognize lease assets and lease liabilities in the balance sheet and disclose key information about the leasing arrangements and cash flows. The ASU is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods, with early adoption permitted, under a modified retrospective adoption. We are currently assessing the potential effects of these changes to our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" as part of a simplification initiative. The update addresses and simplifies several aspects of accounting for share-based payment transactions. The ASU is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption permitted, and is to be applied using either modified retrospective, retrospective, or prospective transition method based on which amendment is being applied. Upon adoption of ASU 2016-09, we elected to change our accounting policy to account for forfeitures as they occur, using a modified retrospective method and determined that a cumulative-effect adjustment to retained earnings would be immaterial at transition during the first quarter of 2017. As a result of the adoption of this ASU, there was no impact on our consolidated financial statements. 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, which has an effective date of the first quarter of fiscal 2022, also applies to employee benefit plan accounting. We are currently assessing the potential effects of these changes to our consolidated financial statements and employee benefit plan accounting. In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments" to reduce diversity in practice in classification of certain transactions in the statement of cash flows. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted, under a retrospective transition adoption. We are currently assessing the potential effects of these changes to our consolidated financial statements. In November 2016, the FASB issued ASU 2016-16, "Intra-Entity Transfers of Assets Other Than Inventory" which requires companies to account for the income tax effects of intercompany transfers of assets other than inventory when the transfer occurs. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted, under a modified retrospective transition adoption. We are currently assessing the potential effects of these changes to our consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, "Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting" to clarify when to account for a change to the terms or conditions of a share-based payment award as a modification. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods, with early adoption permitted. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements. In July 2017, the FASB issued ASU 2017-11, "Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception" to consider “down round” features when determining whether certain equity-linked financial instruments or embedded features are indexed to an entity’s own stock. Entities that present earnings per share ("EPS") under ASC 260 will recognize the effect of a down round feature in a freestanding equity-classified financial instrument only when it is triggered. The effect of triggering such a feature will be recognized as a dividend and a reduction to income available to common shareholders in basic EPS. The ASU is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. We are currently assessing the potential effects of these changes to our consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities" to change how companies account for and disclose hedges. The ASU is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. We are currently assessing the potential effects of these changes to our consolidated financial statements.

Interest rate description			the Fourth Amendment reduced the maximum aggregate lender commitments from $340.0 million to $315.0 million.	In addition, the Third Amendment provided for other changes related to the Credit Agreement including, among other amendments (i) reducing the maximum aggregate lender commitments from $400.0 million to $340.0 million, (ii) increasing the applicable margin by 0.25% with a range between 2.00% and 3.00% per annum for LIBOR-based loans and 1.00% to 2.00% per annum for base-rate loans, based on the applicable consolidated total leverage ratio, and (iii) imposing a requirement that we use designated consolidated cash and cash equivalent balances in excess of $35.0 million to prepay the loans as well as other provisions and restrictions.	r (a) LIBOR (adjusted to reflect any required bank reserves) for an interest period equal to one, two, three, or six months (as selected by us), plus a leverage-based margin or (b) a base rate plus a leverage-based margin; such base rate shall be determined by reference to the highest of (1) the prime rate of interest per annum announced from time to time by Bank of America, N.A., (2) the Federal Funds rate plus 0.50% per annum, and (3) LIBOR (adjusted to reflect any required bank reserves) for a one month interest period on such day plus 1.00% per annum.

Covenant description		certain financial covenants in the Credit Agreement, providing that (i) the consolidated total leverage ratio may not exceed (a) 5.95 to 1 as of March 31, 2017; (b) 6.75 to 1 as of June 30, 2017 and September 30, 2017; (c) 6.50 to 1 as of December 31, 2017 and March 31, 2018; (d) 6.25 to 1 as of June 30, 2018 and September 30, 2018; (e) 6.00 to 1 as of December 31, 2018; and (e) 5.75 to 1 as of March 31, 2019 and thereafter; and (ii) the consolidated secured leverage ratio may not exceed 3.25 to 1 as of the end of any fiscal quarter. The consolidated interest coverage ratio was not amended by the Fifth Amendment. In addition, the Fifth Amendment (i) increased the applicable margin by 0.25% in the event the consolidated total leverage ratio exceeds 6.00 to 1, resulting in a range for the applicable margin between 2.00% and 3.50% per annum for LIBOR-based loans and 1.00 to 2.50% per annum for base-rate loans, according to the consolidated total leverage ratio, and (ii) modified the appraisal delivery requirement from an annual requirement to a semi-annual requirement.	The Fourth Amendment converted the Credit Agreement from a secured revolving credit facility into an asset-based revolving credit facility ("ABL Facility"). Borrowings under the Credit Agreement, as amended, may not exceed a borrowing base equal to the sum of (i) 80% of the aggregate net amount of our eligible accounts receivable, plus (ii) 20% of the aggregate value of any eligible parts inventory, in the event we elect to include eligible parts inventory pursuant to a notice to the administrative agent, plus (iii) 80% of the net in-place eligible compressor equipment, decreased each month by the amount of associated depreciation expense, plus (iv) 80% of the cost of new eligible compressor equipment, and minus (v) the amount of any reserves established by the administrative agent in its discretion. In addition, the Fourth Amendment imposed other requirements, including requirements related to borrowing base reporting on a monthly basis and provisions to permit periodic appraisal and inspection of collateral assets. Pursuant to the Fourth Amendment, certain additional restrictive provisions ("cash dominion provisions") are imposed if an event of default has occurred and is continuing or excess availability under the ABL Facility falls below $30.0 million.
