Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The condensed consolidated financial statements of FINV for the three and six months ended June 30, 2018 and 2017 include the activities of Frank's International C.V. ("FICV"), Blackhawk Group Holdings, LLC ("Blackhawk") and their wholly owned subsidiaries (collectively, the "Company," "we," "us" or "our"). All intercompany accounts and transactions have been eliminated for purposes of preparing these condensed consolidated financial statements. Our accompanying condensed consolidated financial statements have not been audited by our independent registered public accounting firm. The consolidated balance sheet at December 31, 2017 is derived from audited financial statements. However, certain information and footnote disclosures required by generally accepted accounting principles in the United States of America ("GAAP") for complete annual financial statements have been omitted and, therefore, these interim financial statements should be read in conjunction with our audited consolidated financial statements and notes thereto for the year ended December 31, 2017, which are included in our most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission ("SEC") on February 27, 2018 ("Annual Report"). In the opinion of management, these condensed consolidated financial statements, which have been prepared pursuant to the rules of the SEC and GAAP for interim financial reporting, reflect all adjustments, which consisted only of normal recurring adjustments that were necessary for a fair statement of the interim periods presented. The results of operations for interim periods are not necessarily indicative of those for a full year. The condensed consolidated financial statements have been prepared on a historical cost basis using the United States dollar as the reporting currency. Our functional currency is primarily the United States dollar.
Reclassifications	Reclassifications Certain prior-period amounts have been reclassified to conform to the current period's presentation. These reclassifications had no impact on our net income (loss), working capital, cash flows or total equity previously reported. Our financial statements for the three and six months ended June 30, 2017 have been revised to decrease "cost of revenues, services" and increase "cost of revenues, products" by the following immaterial amounts in order to correct a misclassification associated with Blackhawk product costs. While the revisions do impact two financial statement line items, the revisions had no impact on our net income (loss), working capital, cash flows or total equity previously reported (in thousands)
Recent Accounting Pronouncements	Recent Accounting Pronouncements Changes to GAAP are established by the Financial Accounting Standards Board ("FASB") generally in the form of accounting standards updates ("ASUs") to the FASB’s Accounting Standards Codification. We consider the applicability and impact of all accounting pronouncements. ASUs not listed below were assessed and were either determined to be not applicable or are expected to have immaterial impact on our consolidated financial position, results of operations and cash flows. In June 2018, the FASB issued new guidance which is intended to simplify aspects of share-based compensation issued to non-employees by making the guidance consistent with the accounting for employee share-based compensation. The guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those periods. Management is evaluating the provisions of this new accounting guidance, including which period to adopt, and has not determined what impact the adoption will have on our consolidated financial statements. In May 2017, the FASB issued new guidance to clarify and reduce both (i) diversity in practice and (ii) cost and complexity when accounting for a change to the terms and conditions of a share-based payment award. The guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The amendments in this guidance should be applied prospectively to an award modified on or after the adoption date. We adopted the guidance on January 1, 2018 and the adoption did not have an impact on our consolidated financial statements. In January 2017, the FASB issued new accounting guidance for business combinations clarifying the definition of a business. The objective of the guidance is to help companies and other organizations which have acquired or sold a business to evaluate whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. For public entities, the guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. We adopted the guidance on January 1, 2018 and the adoption did not have an impact on our consolidated financial statements. In June 2016, the FASB issued new accounting guidance for credit losses on financial instruments. The guidance includes the replacement of the “incurred loss” approach for recognizing credit losses on financial assets, including trade receivables, with a methodology that reflects expected credit losses, which considers historical and current information as well as reasonable and supportable forecasts. For public entities, the guidance is effective for financial statements issued for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early application is permitted for all entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Management is evaluating the provisions of this new accounting guidance, including which period to adopt, and has not determined what impact the adoption will have on our consolidated financial statements. In February 2016, the FASB issued new accounting guidance for leases. The main objective of the accounting guidance is to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The main difference between previous GAAP and the new guidance is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases. The new guidance requires lessees to recognize assets and liabilities arising from leases on the balance sheet and further defines a lease as a contract that conveys the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. Control over the use of the identified asset means that the customer has both (1) the right to obtain substantially all of the economic benefit from the use of the asset and (2) the right to direct the use of the asset. The accounting guidance requires disclosures by lessees and lessors to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. In July 2018, the FASB amended the new lease accounting standard in an effort to reduce the burden of adoption. With the adoption of the new amended lease accounting standard, companies have the option of electing to apply the new lease accounting standard either on a retrospective or prospective basis. For public entities, the guidance is effective for financial statements issued for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. We are currently evaluating the impact of this ASU on our consolidated financial statements and plan to adopt the new lease accounting standard, as amended, on a prospective basis effective January 1, 2019. While we are still evaluating its impact, we anticipate that the adoption of the lease accounting standard will have an impact to the Company's consolidated balance sheets in addition to the disclosures contained in the notes of its consolidated financial statements. In May 2014, the FASB issued amendments to guidance on the recognition of revenue based upon the entity’s contracts with customers to transfer goods or services. Under the new revenue standard, an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard creates a five-step model that requires companies to exercise judgment when considering the terms of a contract and all relevant facts and circumstances. The standard allows for two transition methods: (a) a full retrospective adoption in which the standard is applied to all periods presented, or (b) a modified retrospective adoption in which the standard is applied only to the most current period presented in the financial statements, including additional disclosures of the standard’s application impact to individual financial statement line items. In July 2015, the FASB deferred the effective date to December 15, 2017 for annual periods, and interim reporting periods within those fiscal years, beginning after that date. We adopted the new revenue standard effective January 1, 2018 using the modified retrospective method. We recognized the cumulative effect of initially applying the new revenue standard as an adjustment to the opening balance of retained earnings. Our adjustment related solely to revenues from certain product sales with bill-and-hold arrangements in our Tubular Sales segment. The comparative information has not been restated and continues to be reported under the accounting standards which were in effect for those periods. The impact to revenue of applying the new revenue recognition standard for the three and six months ended June 30, 2018 was immaterial. We expect the impact of the adoption of the new standard to be immaterial to our financial results on an ongoing basis.
Revenues	Revenues Revenues are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Payment terms on services and products generally range from 30 days to 120 days. Given the short-term nature of our service and product offerings, our contracts do not have a significant financing component and the consideration we receive is generally fixed. Service revenues are recognized over time as services are performed or rendered. We generally perform services either under direct service purchase orders or master service agreements which are supplemented by individual call-out provisions. For customers contracted under such arrangements, an accrual is recorded in unbilled revenue for revenue earned but not yet invoiced. Revenues on product sales are generally recognized at a point in time when the product has shipped and significant risks of ownership have passed to the customer. The sales arrangements typically do not include a right of return or other similar provisions, nor do they contain any other post-delivery obligations. Some of our Tubular Sales and Blackhawk segment customers have requested that we store pipe, connectors and other products purchased from us in our facilities. We recognize revenues for these “bill and hold” sales once the following criteria have been met: (1) there is a substantive reason for the arrangement, (2) the product is identified as the customer's asset, (3) the product is ready for delivery to the customer, and (4) we cannot use the product or direct it to another customer. Practical Expedients We elected to apply certain practical expedients available under the new revenue standard. We elected to expense cost of obtaining contracts, such as sales commissions, when incurred because the amortization period would have been one year or less due to the length of our contracts. We have also elected not to assess immaterial promises in the context of our contracts as performance obligations and to exclude taxes from the assessment of transaction price in arrangements where taxes are collected by the entity from a customer. We do not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less. Because our contracts with customers are short-term in nature and fall within this exemption, we do not have significant unsatisfied performance obligations as defined by the new revenue standard.
