Accounting Policies [Abstract]
Organization, Basis of Presentation, and Significant Accounting Policies	ORGANIZATION, 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 and production well testing. We were incorporated in Delaware in 1981. We are composed of two divisions – Completion Fluids & Products and Water & Flowback Services. 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, 2021 are not necessarily indicative of results that may be expected for the twelve months ended December 31, 2021. The accompanying unaudited consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the U.S. Securities and Exchange Commission (“SEC”) and do not include all information and footnotes required by U.S. generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. These financial statements should be read in conjunction with the financial statements for the year ended December 31, 2020 and notes thereto included in our Annual Report on Form 10-K , which we filed with the SEC on March 5, 2021. Significant Accounting Policies Our significant accounting policies are described in the notes to our consolidated financial statements for the year ended December 31, 2020 included in our Annual Report on Form 10-K . There have been no significant changes in our accounting policies or the application thereof during the second quarter of 2021. 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. Reclassifications Certain previously reported financial information has been reclassified to conform to the current year's presentation. For a discussion of the reclassification of the financial presentation of our former Compression Division as discontinued operations, see Note 2 - “Discontinued Operations”. Other than the discontinued operations presentation, the impact of reclassifications was not significant to the prior year's overall presentation. Unless otherwise noted, amounts and disclosures throughout these Notes to Consolidated Financial Statements relate solely to continuing operations and exclude all discontinued operations. Impairments and Other Charges Impairments of long-lived assets, including identified intangible assets, are determined periodically when indicators of impairment are present. If such indicators are present, the determination of the amount of impairment is based on our judgment as to the future undiscounted operating cash flows to be generated from the relevant assets throughout their remaining estimated useful lives. If these undiscounted cash flows are less than the carrying amount of the related assets, an impairment is recognized for the excess of the carrying value over 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 2021, we recorded an impairment charge of $0.4 million related to idle equipment in our Canada office within our Water & Flowback Services Division. There were no impairments associated with continuing operations during the six months ended June 30, 2020. Foreign Currency Translation We have designated the Euro, the British pound, the Norwegian krone, the Canadian dollar, the Brazilian real, and the Mexican peso as the functional currencies for our operations in Finland and Sweden, the United Kingdom, Norway, Canada, Brazil, and certain of our operations in Mexico, respectively. The United States dollar is the designated functional currency for all of our other non-U.S. operations. The cumulative translation effects of translating the applicable accounts from the functional currencies into the United States 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 $(0.2) million and $(1.0) million during the three and six months ended June 30, 2021, respectively, and $0.8 million and $0.9 million for the three and six months ended June 30, 2020, respectively. Fair Value Measurements We utilize fair value measurements to account for certain items and account balances within our consolidated financial statements. Fair value measurements are utilized on a recurring basis in the determination of the carrying values of certain assets, including our interest in Standard Lithium Ltd. (“Standard Lithium”) and our retained interest in CSI Compressco and liabilities, including the liabilities for the warrants to purchase 11.2 million shares of our common stock (the “Warrants”). See Note 8 - “Fair Value Measurements” for further discussion. Fair value measurements are also utilized on a nonrecurring basis in certain circumstances, including the impairment of long-lived assets (a Level 3 fair value measurement). Supplemental Cash Flow Information Supplemental cash flow information from continuing and discontinued operations is as follows: Six Months Ended 2021 2020 (in thousands) Supplemental cash flow information (1) : Interest paid $ 7,577 $ 35,127 Income taxes paid 853 2,195 Decrease in accrued capital expenditures 1,434 1,820 (1) Prior-year information includes the activity for CSI Compressco for the full period. Current-year information includes activity for CSI Compressco for January only. New Accounting Pronouncements Standards adopted in 2021 In December 2019, the FASB issued Accounting Standards Update (“ASU”) 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” ASU 2019-12 simplifies the accounting for income taxes by eliminating certain exceptions related to intraperiod tax allocation, interim period income tax calculation methodology, and the recognition of deferred tax liabilities for outside basis differences. It also simplifies certain aspects of accounting for franchise taxes and clarifies the accounting for transactions that results in a step-up in the tax basis of goodwill. On January 1, 2021, we adopted ASU 2019-12. The adoption of this standard did not have a material impact on our consolidated financial statements. Standards not yet adopted In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the more timely recognition of losses on financial instruments not accounted for at fair value through net income. The provisions require credit impairments to be measured over the contractual life of an asset and developed with consideration for past events, current conditions, and forecasts of future economic information. Credit impairment will be accounted for as an allowance for credit losses deducted from the amortized cost basis at each reporting date. We are continuing to work through our implementation plan which includes evaluating the impact on our allowance for doubtful accounts methodology, identifying new reporting requirements, and implementing changes to business processes, systems, and controls to support adoption of the standard. Upon adoption, the allowance for doubtful accounts is expected to increase with an offsetting adjustment to retained earnings. Updates at each reporting date after initial adoption will be recorded through selling, general, and administrative expense. ASU 2016-13 has an effective date of the first quarter of fiscal 2023. We continue to assess the potential effects of these changes to our consolidated financial statements.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	DISCONTINUED OPERATIONS On January 29, 2021, we entered into the Purchase and Sale Agreement with Spartan Energy Partners, LP (“Spartan”) pursuant to which we sold the general partner of CSI Compressco, including the IDRs in CSI Compressco and approximately 23.1% of the outstanding limited partner interests in CSI Compressco, in exchange for the combination of $13.4 million in cash paid at closing, $0.5 million in cash payable on the six-month anniversary of the closing and $3.1 million in contingent consideration in the form of cash and/or CSI Compressco common units if CSI Compressco achieves certain financial targets on or before December 31, 2022. Throughout this Quarterly Report, we refer to the transaction with Spartan as the “GP Sale.” As a result of these transactions, we no longer consolidate CSI Compressco as of January 29, 2021. We recognized a primarily non-cash accounting gain of $120.6 million during the six-month period ended June 30, 2021 related to the GP Sale. The gain is included in income (loss) from discontinued operations, net of taxes in our consolidated statement of operations. We will also continue to provide back-office support to CSI Compressco under a Transition Services Agreement for up to one year until CSI Compressco has completed a full separation from our back-office support functions. Our interest in CSI Compressco and the general partner represented substantially all of our Compression Division. In addition, on March 1, 2018, we closed a series of related transactions that resulted in the disposition of our Offshore Division, consisting of our Offshore Services and Maritech segments. Our former Compression and Offshore Divisions are reported as discontinued operations for all periods presented. Our consolidated balance sheets and consolidated statements of operations report discontinued operations separate from continuing operations. Our consolidated statements of comprehensive income, statements of equity and statements of cash flows combine continuing and discontinued operations. Our current-year consolidated statement of operations, statement of comprehensive income, statement of equity and statement of cash flows include CSI Compressco activity for January 1 through January 29. Our consolidated statements of cash flows for the six-month periods ended June 30, 2021 and June 30, 2020 included $3.0 million and $11.2 million, respectively, of capital expenditures related to our former Compression division, as well as $271.8 million of proceeds from long-term debt, $273.9 million of payments of long-term debt, $3.6 million from proceeds from sale of property, plant and equipment, and $1.4 million from amortization of deferred financing discounts, costs and gains for the six-month period ended June 30, 2020. Our current-year results do not include CSI Compressco depreciation or amortization as the assets were considered held for sale.

As of June 30, 2021, we had no outstanding balance and $6.2 million in letters of credit against our asset-based credit agreement (“ABL Credit Agreement”). Because there was no outstanding balance on this ABL Credit Agreement, associated deferred financing costs of $0.9 million as of June 30, 2021, were classified as other long-term assets on the accompanying consolidated balance sheet. As of June 30, 2021, subject to compliance with the covenants, borrowing base, and other provisions of the ABL Credit Agreement that may limit borrowings, we had an availability of $31.7 million under this agreement.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS Financial Instruments Investments Our retained investment in CSI Compressco and our investment in Standard Lithium are recorded based on the quoted market stock price in active markets (a Level 1 fair value measurement). The stock component of consideration received for our arrangement with Standard Lithium is initially recorded as unearned income based on the quoted market price at the time the stock is received, then recognized in income over the contract term. The unearned income associated with the stock component of this agreement is not significant as of June 30, 2021 or December 31, 2020. Changes in the value of stock are recorded in other income (expense) in our consolidated statements of operations Warrants The Warrants are valued using a Black Scholes option valuation model that includes estimates of the volatility of the Warrants (a Level 3 fair value measurement). The Warrants are accounted for as a derivative liability and increases (or decreases) in the fair value of the Warrants are generally associated with increases (or decreases) in the trading price of our common stock and by increases in the volatility of our common stock price, resulting in adjustments to earnings for the associated valuation losses (gains), and resulting in future volatility of our earnings during the period the Warrants are outstanding. The fair value of the Warrants and associated liability increased during the second quarter of 2021 primarily due to the increase in TETRA’s stock price. The estimated volatility as of June 30, 2021 was 60%. The outstanding Warrants expire by December 31, 2021. Recurring and nonrecurring fair value measurements by valuation hierarchy as of June 30, 2021 and December 31, 2020, are as follows: Fair Value Measurements Using Total as of Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Other Observable Inputs Significant Unobservable Inputs Description June 30, 2021 (Level 1) (Level 2) (Level 3) (In Thousands) Investment in CSI Compressco $ 9,638 $ 9,638 $ — $ — Investment in Standard Lithium 6,583 6,583 — — Warrants liability (3,219) — — (3,219) Net asset $ 13,002 Fair Value Measurements Using Total as of Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Other Observable Inputs Significant Unobservable Inputs Description December 31, 2020 (Level 1) (Level 2) (Level 3) (In Thousands) Investment in Standard Lithium $ 2,675 $ 2,675 — $ — Warrants liability (198) — — (198) Net asset $ 2,477 The fair values of cash, restricted cash, accounts receivable, accounts payable, accrued liabilities, short-term borrowings and long-term debt pursuant to TETRA’s ABL Credit Agreement and term credit agreement approximate their carrying amounts.

Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS On July 30, 2021, we entered into an amendment of the ABL Credit Agreement that, among other things, extended the term of the credit facility to May 31, 2025 and revised our commitment to $80.0 million, with a $20.0 million accordion. The amendment increased the availability by adding the value of accrued Unites States receivables, increased the forward rates on accounts receivable for investment grade customers and incorporated a new $15.0 million sub-facility subject to a borrowing base consisting of certain trade receivables and inventory in the United Kingdom. The amendment resulted in an increase of approximately $9.4 million to the borrowing base as of July 30, 2021, compared to the borrowing base prior to the amendment. In connection with the amendment, we also elected to repay the $8.2 million under our term credit agreement that would have become due in 2022. In May 2021, we signed a memorandum of understanding (“MOU”) with CarbonFree Chemicals Holdings, LLC (“CarbonFree”), a carbon capture company with patented technologies that capture CO 2 and mineralize emissions to make commercial, carbon-negative chemicals. During the one-year MOU period, both Companies will work towards a definitive agreement that might include investments by TETRA into CarbonFree, a joint venture, or other commercial arrangements. On July 23, 2021, we entered into a commitment to invest $5.0 million in a convertible note to be issued by CarbonFree. Our investment in Carbon Free is contingent on certain conditions and is expected to be completed during the third quarter of 2021.

Accounting Policies [Abstract]
Nature of operations	Organization We are a geographically diversified oil and gas services company, focused on completion fluids and associated products and services, water management, frac flowback and production well testing. We were incorporated in Delaware in 1981. We are composed of two divisions – Completion Fluids & Products and Water & Flowback Services. 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.
Principles of consolidation policy	Presentation Our unaudited consolidated financial statements include the accounts of our wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in 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, 2021 are not necessarily indicative of results that may be expected for the twelve months ended December 31, 2021. The accompanying unaudited consolidated financial statements have been prepared in accordance with Rule 10-01 of Regulation S-X for interim financial statements required to be filed with the U.S. Securities and Exchange Commission (“SEC”) and do not include all information and footnotes required by U.S. generally accepted accounting principles (“U.S. GAAP”) for complete financial statements. These financial statements should be read in conjunction with the financial statements for the year ended December 31, 2020 and notes thereto included in our Annual Report on Form 10-K
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.
Reclassifications	Reclassifications Certain previously reported financial information has been reclassified to conform to the current year's presentation. For a discussion of the reclassification of the financial presentation of our former Compression Division as discontinued operations, see Note 2 - “Discontinued Operations”. Other than the discontinued operations presentation, the impact of reclassifications was not significant to the prior year's overall presentation. Unless otherwise noted, amounts and disclosures throughout these Notes to Consolidated Financial Statements relate solely to continuing operations and exclude all discontinued operations.
Impairments and other charges	Impairments and Other Charges Impairments of long-lived assets, including identified intangible assets, are determined periodically when indicators of impairment are present. If such indicators are present, the determination of the amount of impairment is based on our judgment as to the future undiscounted operating cash flows to be generated from the relevant assets throughout their remaining estimated useful lives. If these undiscounted cash flows are less than the carrying amount of the related assets, an impairment is recognized for the excess of the carrying value over fair value. Fair
Foreign currency translation policy	Foreign Currency Translation We have designated the Euro, the British pound, the Norwegian krone, the Canadian dollar, the Brazilian real, and the Mexican peso as the functional currencies for our operations in Finland and Sweden, the United Kingdom, Norway, Canada, Brazil, and certain of our operations in Mexico, respectively. The United States dollar is the designated functional currency for all of our other non-U.S. operations. The cumulative translation effects of translating the applicable accounts from the functional currencies into the United States 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 $(0.2) million and $(1.0) million during the three and six months ended June 30, 2021, respectively, and $0.8 million and $0.9 million for the three and six months ended June 30, 2020, respectively.
Fair value measurements	Fair Value Measurements
New accounting pronouncements	New Accounting Pronouncements Standards adopted in 2021 In December 2019, the FASB issued Accounting Standards Update (“ASU”) 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” ASU 2019-12 simplifies the accounting for income taxes by eliminating certain exceptions related to intraperiod tax allocation, interim period income tax calculation methodology, and the recognition of deferred tax liabilities for outside basis differences. It also simplifies certain aspects of accounting for franchise taxes and clarifies the accounting for transactions that results in a step-up in the tax basis of goodwill. On January 1, 2021, we adopted ASU 2019-12. The adoption of this standard did not have a material impact on our consolidated financial statements. Standards not yet adopted In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the more timely recognition of losses on financial instruments not accounted for at fair value through net income. The provisions require credit impairments to be measured over the contractual life of an asset and developed with consideration for past events, current conditions, and forecasts of future economic information. Credit impairment will be accounted for as an allowance for credit losses deducted from the amortized cost basis at each reporting date. We are continuing to work through our implementation plan which includes evaluating the impact on our allowance for doubtful accounts methodology, identifying new reporting requirements, and implementing changes to business processes, systems, and controls to support adoption of the standard. Upon adoption, the allowance for doubtful accounts is expected to increase with an offsetting adjustment to retained earnings. Updates at each reporting date after initial adoption will be recorded through selling, general, and administrative expense. ASU 2016-13 has an effective date of the first quarter of fiscal 2023. We continue to assess the potential effects of these changes to our consolidated financial statements.
