Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and significant accounting policies	Organization and Significant Accounting Policies Organization and Nature of Operations Flotek Industries, Inc. (“Flotek” or the “Company”) is an international energy chemistry technology-driven company that develops and supplies chemistry and services to the oil and gas industry. Flotek also supplied high value compounds to companies that make food and beverages, cleaning products, cosmetics, and other products that are sold in consumer and industrial markets, classified as discontinued operations at December 31, 2018. The Company’s oilfield business includes specialty chemistries and logistics which enable its customers to pursue improved efficiencies in the drilling and completion of their wells. The Company also provides automated bulk material handling, loading facilities, and blending capabilities. In the segment reported as discontinued operations at December 31, 2018, the Company processed citrus oil to produce (1) high value compounds used as additives by companies in the flavors and fragrances markets and (2) environmentally friendly chemistries for use in numerous industries around the world, including the oil and gas (“O&G”) industry. Flotek operates in over 15 domestic and international markets. Customers include major integrated O&G companies, oilfield services companies, independent O&G companies, pressure-pumping service companies, national and state-owned oil companies, and international supply chain management companies. The Company also served customers who purchase non-energy-related citrus oil and related products, including household and commercial cleaning product companies, fragrance and cosmetic companies, and food manufacturing companies, reported as discontinued operations at December 31, 2018. Flotek was initially incorporated under the laws of the Province of British Columbia on May 17, 1985. On October 23, 2001, Flotek changed its corporate domicile to the state of Delaware. Basis of Presentation The accompanying Unaudited Condensed Consolidated Financial Statements and accompanying footnotes (collectively the “Financial Statements”) reflect all adjustments, in the opinion of management, necessary for fair presentation of the financial condition and results of operations for the periods presented. All such adjustments are normal and recurring in nature. The Financial Statements, including selected notes, have been prepared in accordance with applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting and do not include all information and disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for comprehensive financial statement reporting. These interim Financial Statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018 (“Annual Report”). A copy of the Annual Report is available on the SEC’s website, www.sec.gov , under the Company’s ticker symbol (“FTK”) or on Flotek’s website, www.flotekind.com . The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the results to be expected for the year ended December 31, 2019 . During the fourth quarter of 2018, the Company classified the Consumer and Industrial Chemistry Technologies segment as held for sale based on management’s intention to sell this business. The Company’s historical financial statements have been revised to present the operating results of the Consumer and Industrial Chemistry Technologies segment as discontinued operations. The results of operations of this segment are presented as “Income (loss) from discontinued operations” in the statement of operations and the related cash flows of this segment have been reclassified to discontinued operations for all periods presented. The assets and liabilities of the Consumer and Industrial Chemistry Technologies segment have been reclassified to “Assets held for sale” and “Liabilities held for sale”, respectively, in the consolidated balance sheet for all periods presented. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company does not have investments in any unconsolidated subsidiaries. Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current portion of lease liabilities, and operating lease liabilities in the consolidated balance sheets. Finance leases are included in property and equipment, current portion of lease liabilities , and finance lease liabilities in the consolidated balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As the leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Company uses the implicit rate when readily determinable. The lease term is modified to reflect options to extend or terminate the lease when it is reasonably certain the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has some lease agreements that contain both lease and non-lease components. The Company has elected to account for such leases as having a single lease component. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and reported amounts of revenue and expenses. Actual results could differ from these estimates. Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation. The reclassifications did not impact net loss .

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent accounting pronouncements	Recent Accounting Pronouncements Application of New Accounting Standards Effective January 1, 2019, the Company adopted the accounting guidance in Accounting Standards Update (“ASU”) No. 2016-02, “ Leases .” This standard (ASC 842) requires the recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases under previous U.S. GAAP (ASC 840). The Company adopted ASC 842 using the optional transition method. Consequently, the Company’s reporting for the comparative periods presented prior to 2019 in the financial statements will continue to be in accordance with ASC 840. Upon adoption, the Company recorded operating lease ROU assets and corresponding operating lease liabilities, net of deferred rent, of approximately $18.4 million , representing the present value of future lease payments under operating leases with terms of greater than twelve months. The adoption of this standard did not have a material impact on the consolidated statements of operations or cash flows. Refer to Note 4 — “Leases” for further information surrounding adoption of this new standard. Effective January 1, 2019, the Company adopted ASU No. 2018-02, “ Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income .” This standard allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act. Implementation of this standard did not have a material effect on the consolidated financial statements and related disclosures. Effective January 1, 2019, the Company adopted ASU No. 2018-07, “ Improvements to Nonemployee Share-Based Payment Accounting .” This standard expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. Implementation of this standard did not have a material effect on the consolidated financial statements and related disclosures. New Accounting Requirements and Disclosures In June 2016, the FASB issued ASU No. 2016-13, “ Measurement of Credit Losses on Financial Instruments .” This standard replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The pronouncement is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption for the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact the pronouncement will have on the consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU No. 2018-13, “ Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement .” This standard removes, modifies, and adds additional requirements for disclosures related to fair value measurement in ASC 820. The pronouncement is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted in any interim period. The Company is currently evaluating the impact the pronouncement will have on the consolidated financial statements and related disclosures.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations During the fourth quarter of 2018, the Company initiated and began executing a strategic plan to sell its Consumer and Industrial Chemistry Technologies (“CICT”) segment. An investment banking advisory services firm was engaged and actively marketed this segment. The Company met all of the criteria to classify the CICT segment’s assets and liabilities as held for sale in the fourth quarter 2018. The Company has classified the assets, liabilities, and results of operations for this segment as “Discontinued Operations” for all periods presented. Disposal of the CICT reporting segment represented a strategic shift that will have a major effect on the Company’s operations and financial results. On January 10, 2019 , the Company entered into a Share Purchase Agreement with Archer-Daniels-Midland Company (“ADM”) for the sale of all of the shares representing membership interests in its wholly owned subsidiary, Florida Chemical Company, LLC, which represented the CICT segment. Effective February 28, 2019 , the Company completed the sale of the CICT segment to ADM for $175.0 million in cash consideration, with $4.4 million temporarily held in escrow by ADM for post-closing working capital adjustments for up to 90 days and $13.1 million temporarily held in escrow to satisfy potential indemnification claims by ADM with anticipated releases at 6 months , 12 months , and 15 months . As of June 30, 2019, the Company and ADM had not reached an agreement on the post-closing working capital adjustment. As of this filing, the Company is in process of engaging a third party to assist with reaching a conclusion. Concurrent with the closing of the sale of the CICT segment, the Company retained $11.1 million of historical inventory previously held by the CICT segment. In addition, the Company executed a long-term supply agreement for terpene product, which serves as a feedstock to some of the Company’s key value-added products. The term of the agreement runs through September 2023, with an option to extend for an additional year. This agreement secures the Company’s access to a sufficient supply of terpene and includes a minimum annual purchase requirement at variable prices during the term of the agreement.

Revenue from Contracts with Cus

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers Revenues are recognized when control of the promised goods or services is transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. In recognizing revenue for products and services, the Company determines the transaction price of purchase orders or contracts with customers, which may consist of fixed and variable consideration. Determining the transaction price may require significant judgment by management, which includes identifying performance obligations, estimating variable consideration to include in the transaction price, and determining whether promised goods or services are distinct within the context of the contract. Variable consideration typically consists of product returns and is estimated based on the amount of consideration the Company expects to receive. Revenue accruals are recorded on an ongoing basis to reflect updated variable consideration information. For certain contracts, the Company recognizes revenue under the percentage-of-completion method of accounting, measured by the percentage of “costs incurred to date” to the “total estimated costs of completion.” This percentage is applied to the “total estimated revenue at completion” to calculate proportionate revenue earned to date. For the three and six months ended June 30, 2019 and 2018 , the percentage-of-completion revenue accounted for less than 0.1% of total revenue during the respective time periods. This resulted in immaterial unfulfilled performance obligations and immaterial contract assets and/or liabilities, for which the Company did not record adjustments to opening retained earnings as of December 31, 2015 or for any periods previously presented. The vast majority of the Company’s products are sold at a point in time and service contracts are short-term in nature. Sales are billed on a monthly basis with payment terms customarily 30 days from invoice receipt. In addition, sales taxes are excluded from revenues. Disaggregation of Revenue The Company has disaggregated revenues by product sales (point-in-time revenue recognition) and service revenue (over-time revenue recognition), where product sales accounted for over 95% of total revenue for the three and six months ended June 30, 2019 and 2018 . The Company differentiates revenue and operating expenses (excluding depreciation and amortization) based on whether the source of revenue is attributable to products or services. Revenue and operating expenses (excluding depreciation and amortization) disaggregated by revenue source are as follows (in thousands): Three months ended June 30, Six months ended June 30, 2019 2018 2019 2018 Revenue: Products $ 33,632 $ 38,213 $ 75,703 $ 78,142 Services 1,060 1,333 2,246 2,473 $ 34,692 $ 39,546 $ 77,949 $ 80,615 Operating expenses (excluding depreciation and amortization): Products $ 37,798 $ 34,062 $ 81,877 $ 69,247 Services 508 1,482 1,027 2,952 $ 38,306 $ 35,544 $ 82,904 $ 72,199 Arrangements with Multiple Performance Obligations The Company’s contracts with customers may include multiple performance obligations. For such arrangements, the total transaction price is allocated to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation. Standalone selling prices are generally determined based on the prices charged to customers (“observable standalone price”) or an expected cost plus a margin approach. For combined products and services within a contract, the Company accounts for individual products and services separately if they are distinct (i.e. if a product or service is separately identifiable from other items in the contract and if a customer can benefit from it on its own or with other resources that are readily available to the customer). The consideration is allocated between separate products and services within a contract based on the prices at the observable standalone price. For items that are not sold separately, the expected cost plus a margin approach is used to estimate the standalone selling price of each performance obligation. Contract Balances Under revenue contracts for both products and services, customers are invoiced once the performance obligations have been satisfied, at which point payment is unconditional. Accordingly, no revenue contracts give rise to contract assets or liabilities under ASC 606.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill During the second quarter of 2018, the Company recognized a goodwill impairment charge of $37.2 million in the Energy Chemistry Technologies (“ECT”) reporting unit, which resulted from sustained under-performance and lower expectations related to the reporting unit. As a result of these factors, a qualitative analysis, and additional risks associated with the business, the Company concluded that sufficient indicators existed to require an interim quantitative assessment of goodwill for that reporting unit as of June 30, 2018 . The fair value of the reporting unit was estimated based on an analysis of the present value of future discounted cash flows. The significant estimates used in the discounted cash flows model included the Company’s weighted average cost of capital, projected cash flows and the long-term rate of growth. The assumptions were based on the actual historical performance of the reporting unit and took into account a recent weakening of operating results in an improving market environment. The excess of the reporting unit’s carrying value over the estimated fair value was recorded as the goodwill impairment charge in the second quarter 2018 and represented all of the ECT reporting unit’s goodwill. The Company has no reporting units which had a goodwill balance at December 31, 2018 , and there were no acquisitions during the three and six months ended June 30, 2019 .

The Company could borrow under the Credit Facility for working capital, permitted acquisitions, capital expenditures and other corporate purposes. The Credit Facility was to continue in effect until May 10, 2022 . Under terms of the Credit Facility, the Company had total borrowing availability of $75 million under a revolving credit facility, including a sublimit of $10 million that could be used for letters of credit. On March 1, 2019 , the Company repaid the outstanding balance, interest, and fees related to the revolving credit facility, and simultaneously terminated the Credit Facility.

Earnings Per Share [Abstract]
Earnings (loss) per share	Earnings (Loss) Per Share Basic earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding combined with dilutive common share equivalents outstanding, if the effect is dilutive. Potentially dilutive securities were excluded from the calculation of diluted loss per share for the three and six months ended June 30, 2019 and 2018 , since including them would have an anti-dilutive effect on loss per share due to the net loss incurred during the periods. Securities convertible into shares of common stock that were not considered in the diluted loss per share calculations were 0.7 million restricted stock units for the three and six months ended June 30, 2019 , and 0.9 million restricted stock units for the three and six months ended June 30, 2018 .

Fair Value Disclosures [Abstract]
Fair value measurements	Fair Value Measurements Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company categorizes financial assets and liabilities into the three levels of the fair value hierarchy. The hierarchy prioritizes the inputs to valuation techniques used to measure fair value and bases categorization within the hierarchy on the lowest level of input that is available and significant to the fair value measurement. • Level 1 — Quoted prices in active markets for identical assets or liabilities; • Level 2 — Observable inputs other than Level 1, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3 — Significant unobservable inputs that are supported by little or no market activity or that are based on the reporting entity’s assumptions about the inputs. Fair Value of Other Financial Instruments The carrying amounts of certain financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses, approximate fair value due to the short-term nature of these accounts. The Company had total cash of $97.5 million , which consisted of cash equivalents of $46.6 million in a government money market account and cash deposits of $45.2 million in an interest bearing demand deposit account and $5.7 million in operating cash accounts, at June 30, 2019 , and $3.0 million , which consisted of no cash equivalents and cash deposits of $3.0 million in operating cash accounts, at December 31, 2018 . The carrying amount and estimated fair value of the Company’s long-term debt are as follows (in thousands): June 30, 2019 December 31, 2018 Carrying Amount Fair Value Carrying Amount Fair Value Borrowings under Credit Facility — — 49,731 49,731 The carrying amount of borrowings under the Credit Facility approximates its fair value because the interest rates are variable. Assets Measured at Fair Value on a Nonrecurring Basis The Company’s non-financial assets, including property and equipment, goodwill, and other intangible assets are measured at fair value on a non-recurring basis and are subject to fair value adjustment in certain circumstances. During the three months ended June 30, 2018 , the Company recorded an impairment of $37.2 million for goodwill in the Energy Chemistry Technologies reporting unit. No impairments of any of these assets were recognized during the three and six months ended June 30, 2019 .

Income Taxes	Income Taxes A reconciliation of the U.S. federal statutory tax rate to the Company’s effective income tax rate is as follows: Three months ended June 30, Six months ended June 30, 2019 2018 2019 2018 U.S. federal statutory tax rate 21.0 % 21.0 % 21.0 % 21.0 % State income taxes, net of federal benefit 1.7 1.0 1.0 (0.3 ) Non-U.S. income taxed at different rates 0.7 (3.5 ) 1.0 0.3 Reduction in tax benefit related to stock-based awards (1.1 ) 6.5 (1.8 ) (1.5 ) Non-deductible expenses — (9.5 ) (0.3 ) (9.3 ) Research and development credit 0.4 (3.9 ) 0.6 0.6 Increase in valuation allowance (20.7 ) (42.2 ) (17.9 ) (36.0 ) Other (0.4 ) — (0.3 ) — Effective income tax rate 1.6 % (30.6 )% 3.3 % (25.2 )% Fluctuations in effective tax rates have historically been impacted by permanent tax differences with no associated income tax impact, changes in the valuation allowance, changes in state apportionment factors, including the effect on state deferred tax assets and liabilities, and non-U.S. income taxed at different rates. Net deferred tax assets arise due to the recognition of income and expense items for tax purposes, which differ from those used for financial statement purposes. ASC 740, Income Taxes, provides for the recognition of deferred tax assets if realization of such assets is more likely than not. In assessing the need for a valuation allowance in the second quarter of 2018, the Company considered all available objective and verifiable evidence, both positive and negative, including historical levels of pre-tax income (loss) both on a consolidated basis and tax reporting entity basis, legislative developments, and expectations and risks associated with estimates of future pre-tax income. As a result of this analysis, the Company determined that it was more likely than not that it would not realize the benefits of certain deferred tax assets and, therefore, recorded a $15.5 million valuation allowance against the carrying value of net deferred tax assets, except for deferred tax liabilities related to non-amortizable intangible assets and certain state jurisdictions. As all available evidence should be taken into consideration when assessing the need for a valuation allowance, the sale of the CICT segment provided a source of income to support the release of $11.5 million of the valuation allowance which resulted in a deferred tax asset of $18.7 million . As such, the Company reversed this portion of the valuation allowance during the fourth quarter of 2018. The increase in the valuation allowance during the three months ended June 30, 2019, reflects management’s evaluation of deferred tax assets more-likely-than-not to be used after giving consideration to the gain from the sale of the CICT segment and anticipated results of operations. In January 2017, the Internal Revenue Service notified the Company that it would examine the Company’s federal tax returns for the year ended December 31, 2014. The examination included (1) the corporate returns and (2) employment tax matters. The IRS fieldwork has been completed in relation to the corporate returns with no adverse findings. Further discussion of the employment tax matter can be found in Note 18 — “Related Party Transaction.”

Segment Reporting [Abstract]
Business Segment, Geographic and Major Customer Information	Business Segment, Geographic and Major Customer Information Segment Information Operating segments are defined as components of an enterprise for which separate financial information is available that is regularly evaluated by chief operating decision-makers in deciding how to allocate resources and assess performance. The operations of the Company are categorized into one reportable segment: Energy Chemistry Technologies. Energy Chemistry Technologies designs, develops, manufactures, packages, distributes, delivers, and markets reservoir-centric fluid systems, including specialty and conventional chemistries, for use in oil and gas (“O&G”) well drilling, cementing, completion, remediation, and stimulation activities designed to maximize recovery in both new and mature fields. Activities in this segment also include construction and management of automated material handling facilities and management of loading facilities and blending operations for oilfield services companies. The Company evaluates performance based upon a variety of criteria. The primary financial measure is segment operating income. Various functions, including certain sales and marketing activities and general and administrative activities, are provided centrally by the corporate office. Costs associated with corporate office functions, other corporate income and expense items, and income taxes are not allocated to the reportable segment. Summarized financial information of the reportable segments is as follows (in thousands): For the three months ended June 30, Energy Chemistry Technologies Corporate and Other Total 2019 Net revenue from external customers $ 34,692 $ — $ 34,692 Income (loss) from operations (7,651 ) (6,208 ) (13,859 ) Depreciation and amortization 1,933 186 2,119 Capital expenditures 306 — 306 2018 Net revenue from external customers $ 39,546 $ — $ 39,546 Income (loss) from operations (37,929 ) (9,211 ) (47,140 ) Depreciation and amortization 1,797 546 2,343 Capital expenditures 1,167 87 1,254 For the six months ended June 30, Energy Chemistry Technologies Corporate and Other Total 2019 Net revenue from external customers $ 77,949 $ — $ 77,949 Income (loss) from operations (12,984 ) (15,138 ) (28,122 ) Depreciation and amortization 3,718 661 4,379 Capital expenditures 767 — 767 2018 Net revenue from external customers $ 80,615 $ — $ 80,615 Income (loss) from operations (38,095 ) (18,269 ) (56,364 ) Depreciation and amortization 3,566 1,110 4,676 Capital expenditures 2,178 453 2,631 Assets of the Company by reportable segments are as follows (in thousands): June 30, 2019 December 31, 2018 Energy Chemistry Technologies $ 144,106 $ 139,205 Corporate and Other 119,710 28,208 Total segments 263,816 167,413 Held for sale — 118,470 Total assets $ 263,816 $ 285,883 Geographic Information Revenue by country is based on the location where services are provided and products are used.

Commitments and Contingencies Disclosure [Abstract]
Commitments and contingencies	Commitments and Contingencies Class Action Litigation On March 30, 2017, the U.S. District Court for the Southern District of Texas granted the Company’s motion to dismiss the four consolidated putative securities class action lawsuits that were filed in November 2015, against the Company and certain of its officers. The lawsuits were previously consolidated into a single case, and a consolidated amended complaint had been filed. The consolidated amended complaint asserted that the Company made false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. The complaint sought an award of damages in an unspecified amount on behalf of a putative class consisting of persons who purchased the Company’s common stock between October 23, 2014 and November 9, 2015, inclusive. The lead plaintiff appealed the District Court’s decision granting the motion to dismiss. On February 7, 2019, a three-judge panel of the United States Court of Appeals for the Fifth Circuit issued a unanimous opinion affirming the District Court’s judgment of dismissal in its entirety. Other Litigation The Company is subject to routine litigation and other claims that arise in the normal course of business. Management is not aware of any pending or threatened lawsuits or proceedings that are expected to have a material effect on the Company’s financial position, results of operations or liquidity. Concentrations and Credit Risk The majority of the Company’s revenue is derived from the oil and gas industry. Customers include major oilfield services companies, major integrated oil and natural gas companies, independent oil and natural gas companies, pressure pumping service companies, and state-owned national oil companies. This concentration of customers in one industry increases credit and business risks. The Company is subject to concentrations of credit risk within trade accounts receivable, as the Company does not generally require collateral as support for trade receivables. In addition, the majority of the Company’s cash is invested in accounts in two major financial institutions and balances often exceed insurable amounts.

Related Party Transactions [Abstract]
Related party transaction	Related Party Transaction In January 2017, the Internal Revenue Service (“IRS”) notified the Company that it was examining the Company’s federal tax returns for the year ended December 31, 2014. As a result of this examination, the IRS informed the Company on May 1, 2019 that certain employment taxes related to the CEO’s compensation were not properly withheld in 2014 and proposed an adjustment. As the Company has a statutory obligation to collect and withhold employment taxes, management reviewed the CEO’s compensation for tax year 2014, as well as tax years 2015 through 2018, in order to estimate the Company’s potential outstanding employment tax liability in connection with this matter. Upon completion of this review, management believes the Company’s total potential exposure in this matter for 2014 through 2018 is approximately $2.4 million . The CEO’s affiliated companies through which he provided his services have agreed to indemnify the Company for such taxes, and the CEO has executed a personal guaranty in favor of Flotek, supporting this indemnification. As such, the Company recorded an accrued liability for the potential exposure to the IRS in the amount of $2.4 million , with a corresponding receivable, recorded in other current assets, from the CEO’s affiliated companies for the same amount relating to such indemnification obligation.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Unaudited Condensed Consolidated Financial Statements and accompanying footnotes (collectively the “Financial Statements”) reflect all adjustments, in the opinion of management, necessary for fair presentation of the financial condition and results of operations for the periods presented. All such adjustments are normal and recurring in nature. The Financial Statements, including selected notes, have been prepared in accordance with applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting and do not include all information and disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for comprehensive financial statement reporting. These interim Financial Statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018 (“Annual Report”). A copy of the Annual Report is available on the SEC’s website, www.sec.gov , under the Company’s ticker symbol (“FTK”) or on Flotek’s website, www.flotekind.com
Leases	Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current portion of lease liabilities, and operating lease liabilities in the consolidated balance sheets. Finance leases are included in property and equipment, current portion of lease liabilities , and finance lease liabilities in the consolidated balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As the leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The Company uses the implicit rate when readily determinable. The lease term is modified to reflect options to extend or terminate the lease when it is reasonably certain the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has some lease agreements that contain both lease and non-lease components. The Company has elected to account for such leases as having a single lease component.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and reported amounts of revenue and expenses. Actual results could differ from these estimates.
Reclassifications	Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation. The reclassifications did not impact net loss .
Recent accounting pronouncements	Recent Accounting Pronouncements Application of New Accounting Standards Effective January 1, 2019, the Company adopted the accounting guidance in Accounting Standards Update (“ASU”) No. 2016-02, “ Leases .” This standard (ASC 842) requires the recognition of ROU assets and lease liabilities by lessees for those leases classified as operating leases under previous U.S. GAAP (ASC 840). The Company adopted ASC 842 using the optional transition method. Consequently, the Company’s reporting for the comparative periods presented prior to 2019 in the financial statements will continue to be in accordance with ASC 840. Upon adoption, the Company recorded operating lease ROU assets and corresponding operating lease liabilities, net of deferred rent, of approximately $18.4 million , representing the present value of future lease payments under operating leases with terms of greater than twelve months. The adoption of this standard did not have a material impact on the consolidated statements of operations or cash flows. Refer to Note 4 — “Leases” for further information surrounding adoption of this new standard. Effective January 1, 2019, the Company adopted ASU No. 2018-02, “ Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income .” This standard allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act. Implementation of this standard did not have a material effect on the consolidated financial statements and related disclosures. Effective January 1, 2019, the Company adopted ASU No. 2018-07, “ Improvements to Nonemployee Share-Based Payment Accounting .” This standard expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. Implementation of this standard did not have a material effect on the consolidated financial statements and related disclosures. New Accounting Requirements and Disclosures In June 2016, the FASB issued ASU No. 2016-13, “ Measurement of Credit Losses on Financial Instruments .” This standard replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The pronouncement is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption for the fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the impact the pronouncement will have on the consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU No. 2018-13, “ Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement .” This standard removes, modifies, and adds additional requirements for disclosures related to fair value measurement in ASC 820. The pronouncement is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted in any interim period. The Company is currently evaluating the impact the pronouncement will have on the consolidated financial statements and related disclosures.
Earnings (loss) per share	Earnings (Loss) Per Share Basic earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) per common share is calculated by dividing net income (loss) by the weighted average number of common shares outstanding combined with dilutive common share equivalents outstanding, if the effect is dilutive. Potentially dilutive securities were excluded from the calculation of diluted loss per share for the three and six months ended June 30, 2019 and 2018
Fair value measurements	Fair Value Measurements Fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company categorizes financial assets and liabilities into the three levels of the fair value hierarchy. The hierarchy prioritizes the inputs to valuation techniques used to measure fair value and bases categorization within the hierarchy on the lowest level of input that is available and significant to the fair value measurement. • Level 1 — Quoted prices in active markets for identical assets or liabilities; • Level 2 — Observable inputs other than Level 1, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3 — Significant unobservable inputs that are supported by little or no market activity or that are based on the reporting entity’s assumptions about the inputs.
