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, which we filed with the SEC on March 5, 2021.
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 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 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 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).
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. In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848)”, which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) or by another reference rate expected to be discontinued. The amendments are effective for all entities as of March 12, 2020 through December 31, 2022. Entities may elect to apply the amendments for contract modifications as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020. As of June 30, 2021, we have not modified our credit agreements to remove references to LIBOR. We are currently evaluating the impacts of the provisions of ASU 2020-04 on our consolidated financial statements

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.
