Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	BASIS OF PRESENTATION, AND SIGNIFICANT ACCOUNTING POLICIES Organization We are a geographically diversified oil and gas services company, focused on completion fluids and associated products and services, water management, frac flowback, production well testing and offshore rig cooling services, and compression services and equipment. We were incorporated in Delaware in 1981. We are composed of three divisions – Completion Fluids & Products, Water & Flowback Services, and Compression . Unless the context requires otherwise, when we refer to “we,” “us,” and “our,” we are describing TETRA Technologies, Inc. and its consolidated subsidiaries on a consolidated basis. Presentation Our unaudited consolidated financial statements include the accounts of our wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The information furnished reflects all normal recurring adjustments, which are, in the opinion of management, necessary to provide a fair statement of the results for the interim periods. Operating results for the period ended June 30, 2019 are not necessarily indicative of results that may be expected for the twelve months ended December 31, 2019 . We consolidate the financial statements of CSI Compressco LP and its subsidiaries ("CCLP") as part of our Compression Division, as we determined that CCLP is a variable interest entity and we are the primary beneficiary. We control the financial interests of CCLP and have the ability to direct the activities of CCLP that most significantly impact its economic performance through our ownership of its general partner. The share of CCLP net assets and earnings that is not owned by us is presented as noncontrolling interest in our consolidated financial statements. Our cash flows from our investment in CCLP are limited to the quarterly distributions we receive on our CCLP common units and general partner interest (including incentive distribution rights) and the amounts collected for services we perform on behalf of CCLP, as TETRA's capital structure and CCLP's capital structure are separate, and do not include cross default provisions, cross collateralization provisions, or cross guarantees. The accompanying unaudited consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the U.S. Securities and Exchange Commission ("SEC") and do not include all information and footnotes required by U.S. generally accepted accounting principles ("U.S. GAAP") for complete financial statements. These financial statements should be read in conjunction with the financial statements for the year ended December 31, 2018 and notes thereto included in our Annual Report on Form 10-K , which we filed with the SEC on March 4, 2019. Significant Accounting Policies We have added policies for the recording of leases in conjunction with the adoption of the new lease standard discussed in our "Leases" and "New Accounting Pronouncements" sections below. Other than the additional lease policies described herein, there have been no significant changes in our accounting policies or the application of these policies. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management 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. Impairments and Other Charges During the three month period ending June 30, 2019, our Compression Division recorded impairments of $2.3 million on certain units of its low-horsepower compression fleet, reflecting the decision to dispose of these units upon management's determination that refurbishing this equipment was not economic given limited current and forecasted demand for such equipment. A recoverability analysis was performed on the remaining low-horsepower fleet and it was concluded that the remaining fleet was recoverable from estimated future cash flows. Leases As a lessee, unless the lease meets the criteria of short-term and is excluded per our policy election described below, we initially recognize a lease liability and related right-of-use asset on the commencement date. The right-of-use asset represents our right to use an underlying asset and the lease liability represents our obligation to make lease payments to the lessor over the lease term. Long-term operating leases are included in operating lease right-of-use assets, accrued liabilities and other, and operating lease liabilities in our consolidated balance sheet as of June 30, 2019 . Long-term finance leases are not material. We determine whether a contract is or contains a lease at inception of the contract. Where we are a lessee in a contract that includes an option to extend or terminate the lease, we include the extension period or exclude the period covered by the termination option in our lease term, if it is reasonably certain that we would exercise the option. As an accounting policy election, we do not include short-term leases on our balance sheet. Short-term leases include leases with a term of 12 months or less, inclusive of renewal options we are reasonably certain to exercise. The lease payments for short-term leases are included as operating lease costs on a straight-line basis over the lease term in cost of revenues or general and administrative expense based on the use of the underlying asset. We recognize lease costs for variable lease payments not included in the determination of a lease liability in the period in which an obligation is incurred. As allowed by U.S. GAAP, we do not separate nonlease components from the associated lease component for our compression services contracts and instead account for those components as a single component based on the accounting treatment of the predominant component. In our evaluation of whether Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 842 "Leases" or ASC 606 "Revenue from Contracts with Customers" is applicable to the combined component based on the predominant component, we determined the services nonlease component is predominant, resulting in the ongoing recognition of our compression services contracts following ASC 606. Our operating and finance leases are recognized at the present value of lease payments over the lease term. When the implicit discount rate is not readily determinable, we use our incremental borrowing rate to calculate the discount rate used to determine the present value of lease payments. Consistent with other long-lived assets or asset groups that are held and used, we test for impairment of our right-of-use assets when impairment indicators are present. Foreign Currency Translation The cumulative translation effects of translating the applicable accounts from the functional currencies into the U.S. dollar at current exchange rates are included as a separate component of equity. Foreign currency exchange (gains) and losses are included in other (income) expense, net and totaled $(0.8) million and $0.5 million during the three and six months ended June 30, 2019 , respectively, and $(0.6) million and $0.3 million during the three and six months ended June 30, 2018 , respectively. New Accounting Pronouncements Standards adopted in 2019 In February 2016, the FASB issued Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)" to increase comparability and transparency among different organizations. Organizations are required to recognize right-of-use lease assets and lease liabilities in the balance sheet related to the right to use the underlying asset for the lease term. In addition, through improved disclosure requirements, ASC 842 will enable users of financial statements to further understand the amount, timing, and uncertainty of cash flows arising from leases. We adopted the standard effective January 1, 2019. The standard had a material impact on our consolidated balance sheet, specifically, the reporting of our operating leases. The impact in the reporting of our finance leases was insignificant. We chose to transition using a modified retrospective approach which allows for the recognition of a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption rather than the earliest period presented. Comparative information is reported under the accounting standards that were in effect for those periods. In addition, upon transition, we elected the package of practical expedients, which allows us to continue to apply historical lease classifications to existing contracts. Upon adoption, we recognized $60.6 million in operating right-of-use assets, $12.0 million in accrued liabilities and other, and $50.7 million in operating lease liabilities in our consolidated balance sheet. In addition, we also recognized a $2.8 million cumulative effect adjustment to increase retained earnings, primarily as a result of a deferred gain from a previous sale and leaseback transaction on our corporate headquarters facility that was accounted for as an operating lease. Refer to Note K - “Leases” for further information on our leases. In February 2018, the FASB issued ASU 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220)" that gives entities the option to reclassify the income tax effects of the Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. This was effective for us on January 1, 2019, however, as we do not have associated tax effects in accumulated other comprehensive income, there was no impact. In June 2018, the FASB issued ASU 2018-07, “Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting” to align the measurement and classification guidance for share-based payments to nonemployees with the guidance currently applied to employees, with certain exceptions. We adopted this ASU during the three months ended March 31, 2019, with no material impact to our consolidated financial statements. Standards not yet adopted In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the more timely recognition of losses. ASU 2016-13 has an effective date of the first quarter of fiscal 2020. We are currently assessing the potential effects of these changes to our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment," which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. The ASU is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods, with early adoption permitted, under a prospective adoption. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." ASU 2018-15 clarifies the accounting for implementation costs in cloud computing arrangements. ASU 2018-15 is effective for interim and annual reporting periods beginning after December 15, 2019, and early adoption is permitted. We are currently assessing the potential effects of these changes to our consolidated financial statements.

As of June 30, 2019 , subject to compliance with the covenants, borrowing base, and other provisions of the agreement that may limit borrowings, TETRA had an availability of $40.6 million under this agreement. There was no balance outstanding under the CCLP asset-based credit agreement ("CCLP Credit Agreement") as of June 30, 2019 . On June 26, 2019, CCLP entered into an amendment of the CCLP Credit Agreement that, among other things, revised and increased the borrowing base, including adding the value of certain CCLP inventory in the determination of the borrowing base. As of June 30, 2019 , and subject to compliance with the covenants, borrowing base, and other provisions of the agreements that may limit borrowings under the CCLP Credit Agreement, CCLP had availability of $22.2 million . TETRA and CCLP credit and senior note agreements contain certain affirmative and negative covenants, including covenants that restrict the ability to pay dividends or other restricted payments.

Series A Preferred Units [Abstract]
CCLP Series A Preferred Units	CCLP SERIES A CONVERTIBLE PREFERRED UNITS During 2016, CCLP issued an aggregate of 6,999,126 of CSI Compressco LP Series A Convertible Preferred Units representing limited partner interests in CCLP (the “CCLP Preferred Units”) for a cash purchase price of $11.43 per CCLP Preferred Unit (the “Issue Price”). We purchased 874,891 of the CCLP Preferred Units at the aggregate Issue Price of $10.0 million . Unless otherwise redeemed for cash, a ratable portion of the CCLP Preferred Units has been, and will continue to be, converted into CCLP common units on the eighth day of each month over a period of thirty months that began in March 2017 and will end in August 2019 (each, a “Conversion Date”). Based on the number of CCLP Preferred Units outstanding as of June 30, 2019 , the maximum aggregate number of CCLP common units that could be required to be issued pursuant to the conversion provisions of the CCLP Preferred Units is approximately 4.3 million CCLP common units; however, CCLP may, at its option, pay cash, or a combination of cash and common units, to the holders of the CCLP Preferred Units instead of issuing common units on any Conversion Date, subject to certain restrictions as described in the Second Amended and Restated CCLP Partnership Agreement and the CCLP Credit Agreement. Beginning with the January 2019 Conversion Date, CCLP has elected to redeem the remaining CCLP Preferred Units for cash, resulting in 1,870,681 CCLP Preferred Units being redeemed during the six months ended June 30, 2019 for $19.8 million , which includes approximately $0.9 million of redemption premium that was paid and charged to other (income) expense, net in the accompanying consolidated statements of operations. The total number of CCLP Preferred Units outstanding as of June 30, 2019 was 751,736 , of which we held 94,409 . The final redemption of the remaining outstanding CCLP Preferred Units, along with a final cash payment made in lieu of paid in kind units for the quarter ended June 30, 2019 , occurred on August 8, 2019 , for an aggregate cash payment of $5.0 million of which $0.6 million was paid to us. Based on the conversion provisions of the CCLP Preferred Units, calculated as of June 30, 2019 , using the trading prices of the common units over the prior month, along with other factors, and as otherwise impacted by the existence of certain conditions related to the CCLP common units (the "Conversion Price"), the theoretical number of CCLP common units that would be issued if all of the outstanding CCLP Preferred Units were converted on June 30, 2019 on the same basis as the monthly conversions would be approximately 2.7 million CCLP common units, with an aggregate market value of $9.7 million . If converted to CCLP common units, a $1 decrease in the Conversion Price would result in the issuance of 1.3 million additional CCLP common units pursuant to these conversion provisions.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Hedge Contracts	FAIR VALUE MEASUREMENTS Financial Instruments CCLP Preferred Units The CCLP 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 CCLP's common units compared to a volatility analysis of equity prices of CCLP's 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. Warrants The Warrants are valued using a Black Scholes option valuation model that includes implied volatility of the trading price (a Level 3 fair value measurement). Contingent Consideration The fair value of the remaining contingent consideration associated with the February 2018 acquisition of SwiftWater Energy Services, LLC ("SwiftWater") is based on a probability simulation utilizing forecasted revenues and EBITDA of the water management business of SwiftWater and all of our pre-existing operations in the Permian Basin (a Level 3 fair value measurement). At June 30, 2019 , based on a forecast of SwiftWater 2019 revenues and EBITDA, the estimated fair value for the liability associated with the remaining contingent purchase price consideration was $0.2 million , resulting in $0.4 million and $0.8 million being credited to other (income) expense, net, during the three and six months ended June 30, 2019 , respectively. During the three months ended June 30, 2019 , the sellers received a payment of $10.0 million based on SwiftWater's performance during 2018. In addition, as part of the purchase of JRGO Energy Services LLC ("JRGO") during December 2018, the sellers were paid contingent consideration of $1.4 million during the three month period ended June 30, 2019, based on JRGO's performance during the fourth quarter of 2018. Derivative Contracts We and CCLP each enter into short term foreign currency forward derivative contracts with third parties as part of a program designed to mitigate the currency exchange rate risk exposure on selected transactions of certain foreign subsidiaries. As of June 30, 2019 , we and CCLP had the following foreign currency derivative contracts outstanding relating to portions of our foreign operations: Derivative Contracts US Dollar Notional Amount Traded Exchange Rate Settlement Date (In Thousands) Forward purchase Euro $ 7,333 1.13 9/19/2019 Forward purchase Euro 2,025 1.15 9/19/2019 Forward purchase pounds sterling 4,285 1.26 7/19/2019 Forward purchase Mexican peso 780 19.23 7/19/2019 Forward purchase Norwegian krone 552 8.69 7/19/2019 Forward sale Mexican peso 7,858 19.09 7/19/2019 Derivative Contracts British Pound Notional Amount Traded Exchange Rate Settlement Date (In Thousands) Forward purchase Euro 1,780 0.89 7/19/2019 Derivative Contracts Swedish Krona Notional Amount Traded Exchange Rate Settlement Date (In Thousands) Forward purchase Euro 22,270 10.60 7/19/2019 Under this program, we and CCLP may enter into similar derivative contracts from time to time. Although contracts pursuant to this program will serve as an economic hedge of the cash flow of our currency exchange risk exposure, they are not 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 foreign currency derivative instruments are based on quoted market values (a Level 2 fair value measurement). The fair values of our and CCLP's foreign currency derivative instruments as of June 30, 2019 and December 31, 2018 , are as follows: Foreign currency derivative instruments Balance Sheet Location Fair Value at June 30, 2019 Fair Value at December 31, 2018 (In Thousands) Forward purchase contracts Current assets $ 147 $ 41 Forward sale contracts Current assets 64 76 Forward sale contracts Current liabilities — (126 ) Forward purchase contracts Current liabilities (23 ) (168 ) Net asset (liability) $ 188 $ (177 ) None of our foreign currency derivative contracts contain credit risk related contingent features that would require us to post assets or collateral for contracts that are classified as liabilities. During the three and six month periods ended June 30, 2019 , we recognized $0.2 million and $0.7 million of net (gains) losses , respectively, reflected in other (income) expense, net, associated with our foreign currency derivative program. During the three and six months ended June 30, 2018 , we recognized $(0.7) million and $(0.8) million of net (gains) losses , respectively, reflected in other (income) expense, net, associated with our foreign currency derivative program.

The fair values of the publicly traded CCLP 7.25% Senior Notes at June 30, 2019 and December 31, 2018 , were approximately $267.1 million and $266.3 million , respectively. Those fair values compare to the face amount of $ 295.9 million both at June 30, 2019 and December 31, 2018 . The fair values of the CCLP 7.50% Senior Secured Notes at June 30, 2019 and December 31, 2018 were approximately $344.8 million and $332.5 million , respectively. These fair values compare to aggregate principal amount of such notes at both June 30, 2019 and December 31, 2018 , of $350.0 million . We based the fair values of the CCLP 7.25% Senior Notes and the CCLP 7.50% Senior Secured Notes as of June 30, 2019 on recent trades for these notes.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Litigation We are named defendants in several lawsuits and respondents in certain governmental proceedings arising in the ordinary course of business. While the outcome of lawsuits or other proceedings against us cannot be predicted with certainty, management does not consider it reasonably possible that a loss resulting from such lawsuits or other proceedings in excess of any amounts accrued has been incurred that is expected to have a material adverse impact on our financial condition, results of operations, or liquidity. Contingencies of Discontinued Operations In early 2018, we closed the Maritech Asset Purchase Agreement with Orinoco Natural Resources, LLC ("Orinoco") that provided for the purchase by Orinoco of Maritech's remaining oil and gas properties and related assets. Also in early 2018, we closed the Maritech Membership Interest Purchase Agreement with Orinoco that provided for the purchase by Orinoco of all of the outstanding membership interests in Maritech. As a result of these transactions, we have effectively exited the business of our Maritech segment and Orinoco assumed all of Maritech's abandonment and decommissioning obligations. To the extent that Maritech or Orinoco fails to perform the abandonment and decommissioning work required, we, as the former parent company of Maritech, may be required to perform the abandonment and decommissioning work. Pursuant to a Bonding Agreement entered into as part of these transactions (the "Bonding Agreement"), Orinoco provided non-revocable performance bonds in an aggregate amount of $46.8 million to cover the performance by Orinoco and Maritech of the asset retirement obligations of Maritech and agreed to replace, within 90 days following the closing, the initial bonds delivered at closing with other non-revocable performance bonds, meeting certain requirements, in the aggregate sum of $47.0 million. Orinoco further agreed to replace, within 180 days following the closing, such replacement performance bonds with a maximum of three performance bonds in the aggregate sum of $47.0 million, meeting certain requirements. In the event Orinoco does not provide either tranche of replacement bonds, Orinoco is required to make certain cash escrow payments to us. The payment obligations of Orinoco under the Bonding Agreement were guaranteed by Thomas M. Clarke and Ana M. Clarke pursuant to a separate guaranty agreement (the “Clarke Bonding Guaranty Agreement”). Orinoco has not delivered such replacement bonds and it has not made any of the agreed upon cash escrow payments and we filed a lawsuit against Orinoco and the Clarkes to enforce the terms of the Bonding Agreement and the Clarke Bonding Guaranty Agreement. Each party filed a motion for summary judgment in the lawsuit asserting its respective claims. A summary judgment was granted in favor of Orinoco and the Clarkes which has the effect of dismissing our present claims for the replacement bonds and the escrow payments provided for in the Bonding Agreement. We plan to seek reconsideration of the decision by the court and/or file an appeal of the summary judgment. The non-revocable performance bonds delivered at the closing remain in effect.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	REVENUE FROM CONTRACTS WITH CUSTOMERS Performance Obligations. Revenue is generally recognized when we transfer control of our products or services to our customers. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products or providing services to our customers. Product Sales. Product sales revenues are generally recognized when we ship products from our facility to our customer. The product sales for our Completion Fluid & Products Division consist primarily of clear brine fluids ("CBFs"), additives, and associated manufactured products. Product sales for our Water & Flowback Services Division are typically attributed to specific performance obligations within certain production testing service arrangements. Parts and equipment sales comprise the product sales for the Compression Division. Services . Service revenues represent revenue recognized over time, as our customer arrangements typically provide agreed upon day-rates (monthly service rates for compression services) and we recognize service revenue based upon the number of days services have been performed. Service revenue recognized over time is associated with a majority of our Water & Flowback Services Division arrangements, compression service and aftermarket service contracts within our Compression Division, and a small portion of Completion Fluids & Products Division revenue that is associated with completion fluid service arrangements. With the exception of the initial terms of the compression services contracts for medium- and high-horsepower compressor packages of our Compression Division, our customer contracts are generally for terms of one year or less. The majority of the service arrangements in the Water & Flowback Services Division are for a period of 90 days or less. Within our Compression Division service revenue, most aftermarket service revenues are recognized at a point in time when we transfer control of our products and complete the delivery of services to our customers. We receive cash equal to the invoice price for most product sales and services and payment terms typically range from 30 to 60 days from the date we invoice our customer. Since the period between when we deliver products or services and when the customer pays for such products or services is not expected to exceed one year, we have elected not to calculate or disclose a financing component for our customer contracts. Depending on the terms of the arrangement, we may also defer the recognition of revenue for a portion of the consideration received because we have to satisfy a future performance obligation. For example, consideration received from customers during the fabrication of new compressor packages is typically deferred until control of the compressor package is transferred to our customer. For any arrangements with multiple performance obligations, we use management's estimated selling price to determine the stand-alone selling price for separate performance obligations. For revenue associated with mobilization of service equipment as part of a service contract arrangement, such revenue, if significant, is deferred and amortized over the estimated service period. As of June 30, 2019 , we had $45.3 million of remaining performance obligations related to our compression service contracts. As a practical expedient, this amount does not reflect revenue for compression service contracts whose original expected duration is less than 12 months and does not consider the effects of the time value of money. T he remaining performance obligations are expected to be recognized through 2022 as follows (in thousands): 2019 2020 2021 2022 2023 Total (In Thousands) Compression service contracts remaining performance obligations $ 19,830 $ 19,279 $ 6,108 $ 101 $ — $ 45,318 Sales taxes, value added taxes, and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. We have elected to recognize the cost for freight and shipping costs as part of cost of product sales when control over our products (i.e. delivery) has transferred to the customer. Use of Estimates. In recognizing revenue for variable consideration arrangements, the amount of variable consideration recognized is limited so that it is probable that significant amounts of revenues will not be reversed in future periods when the uncertainty is resolved. For products returned by the customer, we estimate the expected returns based on an analysis of historical experience. For volume discounts earned by the customer, we estimate the discount (if any) based on our estimate of the total expected volume of products sold or services to be provided to the customer during the discount period. In certain contracts for the sale of CBF, we may agree to issue credits for the repurchase of reclaimable used fluids from certain customers at an agreed price that is based on the condition of the fluids. For sales of CBF, we adjust the revenue recognized in the period of shipment by the estimated amount of the credit expected to be issued to the customer, and this estimate is based on historical experience. As of June 30, 2019 , the amount of remaining credits expected to be issued for the repurchase of reclaimable used fluids was $4.2 million tha t were recorded in inventory (right of return asset) and accounts payable. T here were no material differences between amounts recognized during the three and six month periods ended June 30, 2019 , compared to estimates made in a prior period from these variable consideration arrangements. Contract Assets and Liabilities. We consider contract assets to be trade accounts receivable when we have an unconditional right to consideration and only the passage of time is required before payment is due. In certain instances, particularly those requiring customer specific documentation prior to invoicing, our invoicing of the customer is delayed until certain documentation requirements are met. In those cases, we recognize a contract asset rather than a billed trade accounts receivable until we are able to invoice the customer. Our contract asset balances, primarily associated with these documentation requirements, were $35.4 million and $44.2 million as of June 30, 2019 and December 31, 2018 , respectively. Contract assets, along with billed trade accounts receivable, are included in trade accounts receivable in our consolidated balance sheets. We classify contract liabilities as Unearned Income in our consolidated balance sheets. Such deferred revenue typically results from advance payments received on orders for new compressor equipment prior to the time such equipment is completed and transferred to the customer in accordance with the customer contract. The following table reflects the changes in our contract liabilities for the periods indicated: Six Months Ended 2019 2018 (In Thousands) Unearned Income, beginning of period $ 25,333 $ 17,050 Additional unearned income 84,456 59,360 Revenue recognized (78,119 ) (47,276 ) Unearned income, end of period $ 31,670 $ 29,134 During the six month period ended June 30, 2019 , we recognized in product sales revenue of $19.1 million from unearned income that was deferred as of December 31, 2018. During the six months ended June 30, 2018, we recognized in product sales revenue of $15.4 million from unearned income that was deferred as of our adoption of ASC 606 on January 1, 2018. Contract Costs. As of June 30, 2019 , contract costs were immaterial. Disaggregation of Revenue. We disaggregate revenue from contracts with customers into Product Sales and Services within each segment, as noted in our three reportable segments in Note I . In addition, we disaggregate revenue from contracts with customers by geography based on the following table below.

Leases [Abstract]
Leases	LEASES We have operating leases for some of our transportation equipment, office space, warehouse space, operating locations, and machinery and equipment. We have finance leases for certain storage tanks and equipment rentals. These finance leases are not material to our financial statements. Our leases have remaining lease terms ranging from 1 to 16 years . Some of our leases have options to extend for various periods, while some have termination options with prior notice of generally 30 days or six months. The office space, warehouse space, operating location leases, and machinery and equipment leases generally require us to pay all maintenance and insurance costs. We do not have leases that have not yet commenced that create significant rights and obligations. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Variable rent expense was not material. Our corporate headquarters facility located in The Woodlands, Texas, was sold on December 31, 2012, pursuant to a sale and leaseback transaction. As a condition to the consummation of the purchase and sale of the facility, the parties entered into a lease agreement for the facility having an initial lease term of 15 years , which is classified as an operating lease. Under the terms of the lease agreement, we have the ability to extend the lease for five successive five year periods at base rental rates to be determined at the time of each extension. Components of lease expense, included in either cost of revenues or general and administrative expense based on the use of the underlying asset, are as follows (inclusive of lease expense for leases not included on our consolidated balance sheet based on our accounting policy election to exclude leases with a term of 12 months or less): Three Months Ended June 30, 2019 Six Months Ended June 30, 2019 (In Thousands) Operating lease expense $ 4,987 $ 10,031 Short-term lease expense 9,552 20,713 Total lease expense $ 14,539 $ 30,744 Supplemental cash flow information: Six Months Ended June 30, 2019 (In Thousands) Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows - operating leases $ 9,398 Right-of-use assets obtained in exchange for lease obligations: Operating leases $ 4,881 Supplemental balance sheet information: June 30, 2019 (In Thousands) Operating leases: Operating lease right-of-use assets $ 57,924 Accrued liabilities and other $ 12,652 Operating lease liabilities 47,398 Total operating lease liabilities $ 60,050 Additional operating lease information: June 30, 2019 Weighted average remaining lease term: Operating leases 6.88 Years Weighted average discount rate: Operating leases 9.41 % Future minimum lease payments by year and in the aggregate, under non-cancelable operating leases with terms in excess of one year consist of the following at June 30, 2019 : Operating Leases (In Thousands) Remainder of 2019 $ 8,948 2020 15,996 2021 11,702 2022 9,107 2023 7,844 Thereafter 29,391 Total lease payments 82,988 Less imputed interest (22,938 ) Total lease liabilities $ 60,050 At June 30, 2019 , future minimum rental receipts under a non-cancelable sublease for office space in one of our locations totaled $5.9 million .

Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS Contingencies of Discontinued Operations Part of the consideration we received in the March 1, 2018 disposition of our Offshore Division was a promissory note in the original principal amount of $7.5 million (the “Epic Promissory Note”) payable by Epic Companies, LLC (“Epic Companies,” formerly known as Epic Offshore Specialty, LLC) to us in full, together with interest at a rate of 1.52% per annum, on December 31, 2019, along with a personal guaranty agreement from Thomas M. Clarke and Ana M. Clarke guaranteeing the payment obligations of Epic Companies pursuant to the Epic Promissory Note (the “Clarke Promissory Note Guaranty Agreement”). Additionally, pursuant to the Equity Interest Purchase Agreement (the “Offshore Services Purchase Agreement”) and other agreements with Epic Companies, certain other amounts relating to the Offshore Division totaling approximately $1.4 million as of June 30, 2019 are payable to us. In August 2019, certain creditors of Epic Companies filed an involuntary petition against Epic Companies under Chapter 7 of the bankruptcy code in the Eastern District of Louisiana. Although the Epic Promissory Note is not currently due and is guaranteed by the Clarke Promissory Note Guaranty Agreement, we continue to monitor this matter and there can be no assurance that future developments, including those involving the financial condition of Epic Companies or relating to the involuntary bankruptcy proceeding, may or may not adversely impact our ability to timely collect amounts owed to us by Epic Companies pursuant to the Offshore Services Purchase Agreement and the Epic Promissory Note. CCLP Series A Convertible Preferred Units On August 8, 2019, the remaining 375,868 CCLP Preferred Units, of which we held 47,205 , were redeemed, along with a final cash payment made in lieu of paid in kind units for the quarter ended June 30, 2019, for an aggregate cash payment of $5.0 million of which $0.6 million was paid to us.

Accounting Policies [Abstract]
Principles of consolidation policy	Our unaudited consolidated financial statements include the accounts of our wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The information furnished reflects all normal recurring adjustments, which are, in the opinion of management, necessary to provide a fair statement of the results for the interim periods. Operating results for the period ended June 30, 2019 are not necessarily indicative of results that may be expected for the twelve months ended December 31, 2019 . We consolidate the financial statements of CSI Compressco LP and its subsidiaries ("CCLP") as part of our Compression Division, as we determined that CCLP is a variable interest entity and we are the primary beneficiary. We control the financial interests of CCLP and have the ability to direct the activities of CCLP that most significantly impact its economic performance through our ownership of its general partner. The share of CCLP net assets and earnings that is not owned by us is presented as noncontrolling interest in our consolidated financial statements. Our cash flows from our investment in CCLP are limited to the quarterly distributions we receive on our CCLP common units and general partner interest (including incentive distribution rights) and the amounts collected for services we perform on behalf of CCLP, as TETRA's capital structure and CCLP's capital structure are separate, and do not include cross default provisions, cross collateralization provisions, or cross guarantees. The accompanying unaudited consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the U.S. Securities and Exchange Commission ("SEC") and do not include all information and footnotes required by U.S. generally accepted accounting principles ("U.S. GAAP") for complete financial statements. These financial statements should be read in conjunction with the financial statements for the year ended December 31, 2018 and notes thereto included in our Annual Report on Form 10-K , which we filed with the SEC on March 4, 2019.
Use of estimates policy	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management 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.
Lessee, Leases [Policy Text Block]	Leases As a lessee, unless the lease meets the criteria of short-term and is excluded per our policy election described below, we initially recognize a lease liability and related right-of-use asset on the commencement date. The right-of-use asset represents our right to use an underlying asset and the lease liability represents our obligation to make lease payments to the lessor over the lease term. Long-term operating leases are included in operating lease right-of-use assets, accrued liabilities and other, and operating lease liabilities in our consolidated balance sheet as of June 30, 2019 . Long-term finance leases are not material. We determine whether a contract is or contains a lease at inception of the contract. Where we are a lessee in a contract that includes an option to extend or terminate the lease, we include the extension period or exclude the period covered by the termination option in our lease term, if it is reasonably certain that we would exercise the option. As an accounting policy election, we do not include short-term leases on our balance sheet. Short-term leases include leases with a term of 12 months or less, inclusive of renewal options we are reasonably certain to exercise. The lease payments for short-term leases are included as operating lease costs on a straight-line basis over the lease term in cost of revenues or general and administrative expense based on the use of the underlying asset. We recognize lease costs for variable lease payments not included in the determination of a lease liability in the period in which an obligation is incurred. As allowed by U.S. GAAP, we do not separate nonlease components from the associated lease component for our compression services contracts and instead account for those components as a single component based on the accounting treatment of the predominant component. In our evaluation of whether Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 842 "Leases" or ASC 606 "Revenue from Contracts with Customers" is applicable to the combined component based on the predominant component, we determined the services nonlease component is predominant, resulting in the ongoing recognition of our compression services contracts following ASC 606. Our operating and finance leases are recognized at the present value of lease payments over the lease term. When the implicit discount rate is not readily determinable, we use our incremental borrowing rate to calculate the discount rate used to determine the present value of lease payments. Consistent with other long-lived assets or asset groups that are held and used, we test for impairment of our right-of-use assets when impairment indicators are present.
Foreign currency translation policy	Foreign Currency Translation The cumulative translation effects of translating the applicable accounts from the functional currencies into the U.S. dollar at current exchange rates are included as a separate component of equity. Foreign currency exchange (gains) and losses are included in other (income) expense, net and totaled $(0.8) million and $0.5 million during the three and six months ended June 30, 2019 , respectively, and $(0.6) million and $0.3 million during the three and six months ended June 30, 2018 , respectively.
New Accounting Pronouncements policy	New Accounting Pronouncements Standards adopted in 2019 In February 2016, the FASB issued Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)" to increase comparability and transparency among different organizations. Organizations are required to recognize right-of-use lease assets and lease liabilities in the balance sheet related to the right to use the underlying asset for the lease term. In addition, through improved disclosure requirements, ASC 842 will enable users of financial statements to further understand the amount, timing, and uncertainty of cash flows arising from leases. We adopted the standard effective January 1, 2019. The standard had a material impact on our consolidated balance sheet, specifically, the reporting of our operating leases. The impact in the reporting of our finance leases was insignificant. We chose to transition using a modified retrospective approach which allows for the recognition of a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption rather than the earliest period presented. Comparative information is reported under the accounting standards that were in effect for those periods. In addition, upon transition, we elected the package of practical expedients, which allows us to continue to apply historical lease classifications to existing contracts. Upon adoption, we recognized $60.6 million in operating right-of-use assets, $12.0 million in accrued liabilities and other, and $50.7 million in operating lease liabilities in our consolidated balance sheet. In addition, we also recognized a $2.8 million cumulative effect adjustment to increase retained earnings, primarily as a result of a deferred gain from a previous sale and leaseback transaction on our corporate headquarters facility that was accounted for as an operating lease. Refer to Note K - “Leases” for further information on our leases. In February 2018, the FASB issued ASU 2018-02, "Income Statement-Reporting Comprehensive Income (Topic 220)" that gives entities the option to reclassify the income tax effects of the Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings. This was effective for us on January 1, 2019, however, as we do not have associated tax effects in accumulated other comprehensive income, there was no impact. In June 2018, the FASB issued ASU 2018-07, “Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting” to align the measurement and classification guidance for share-based payments to nonemployees with the guidance currently applied to employees, with certain exceptions. We adopted this ASU during the three months ended March 31, 2019, with no material impact to our consolidated financial statements. Standards not yet adopted In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments." ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the more timely recognition of losses. ASU 2016-13 has an effective date of the first quarter of fiscal 2020. We are currently assessing the potential effects of these changes to our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, "Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment," which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. The ASU is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods, with early adoption permitted, under a prospective adoption. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." ASU 2018-15 clarifies the accounting for implementation costs in cloud computing arrangements. ASU 2018-15 is effective for interim and annual reporting periods beginning after December 15, 2019, and early adoption is permitted. We are currently assessing the potential effects of these changes to our consolidated financial statements.
