Basis of Presentation [Abstract]
Basis of Presentation	Note 1. Basis of Presentation  Nature of Business  NCS Multistage Holdings, Inc., a Delaware corporation, through its wholly owned subsidiaries and subsidiaries for which we have a controlling voting interest (collectively referred to as the “Company,” “NCS,” “we,” “ our ” and “us”), is primarily engaged in providing engineered products and support services for oil and natural gas well completions and field development strategies. We offer our products and services primarily to exploration and production companies for use in onshore wells. We operate through service facilities principally located in Houston, Midland and Corpus Christi, Texas; Tulsa and Oklahoma City, Oklahoma; Billings, Montana; Morgantown, West Virginia; Calgary, Red Deer, Grande Prairie and Estevan, Canada; Neuquen, Argentina and Stavanger, Norway.  Basis of Presentation  Our accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), issued by the Securities Exchange Commission (“SEC”) and have not been audited by our independent registered public accounting firm. The Condensed Consolidated Balance Sheet at December 31, 2018 is derived from our audited financial statements. However, certain information and footnote disclosures required by GAAP for complete annual financial statements have been omitted or condensed as permitted by the rules and regulations of the SEC, and, therefore, these interim financial statements should be read in conjunction with our audited financial statements included in our Annual Report on Form 10-K filed with the SEC on March 8, 2019. 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. All intercompany accounts and transactions have been eliminated for purposes of preparing these condensed consolidated financial statements.  Summary of New Significant Accounting Policy  Inventories  Inventories consist primarily of raw material, product components, assembled products, certain components used to internally construct our frac isolation assemblies and chemicals, in raw material or finished goods, used in our tracer diagnostics services. Inventories are stated at the lower of cost or estimated net realizable value. Cost is determined at standard costs approximating the first-in first-out basis. We continuously evaluate inventories, based on an analysis of inventory levels, historical sales experience and future sales forecasts, to determine obsolete, slow-moving and excess inventory. Adjustments to reduce such inventory to its estimated recoverable value have been recorded as an adjustment to cost of sales.  Recent Accounting Pronouncements  Pronouncement Adopted in 2019  In February 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) , which requires lessees to recognize a right-of-use (“ROU”) asset and a lease liability for all leases with terms longer than 12 months. Under the new standard, lessees need to recognize leases on their balance sheets as lease liabilities with corresponding ROU assets. We adopted the standard effective January 1, 2019, using a modified retrospective transition method and applying certain optional practical expedients. NCS elected an optional transition method that allowed application of the new standard at the adoption date and the recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption with no adjustment to previously reported results. We also elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed the carry forward of historical lease classification as well as additional practical expedients related to land easements, short-term leases, and non-lease components. We did not elect the practical expedient related to hindsight. The standard had a material impact on our condensed consolidated balance sheet but did not materially impact our condensed consolidated statements of operations or condensed consolidated statements of cash flows. Adoption of the new standard resulted in the recording of ROU assets and lease liabilities of $7.5 million on January 1, 2019. See “Note 8. Leases” for more information. Pronouncements Not Yet Effective  In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40) . The ASU aligns the requirements to capitalize implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements to capitalize implementation costs incurred to develop or obtain internal-use software. For public entities, this guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. We are currently evaluating the impact of the adoption of this guidance.  In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) . The ASU modifies, removes and adds certain disclosure requirements on fair value measurements. For public entities, this guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted for all amendments. Further, entities may early adopt eliminated or modified disclosure requirements and delay the adoption of all new disclosure requirements until the effective date. We are currently evaluating the impact of the adoption of this guidance.

Revenues [Abstract]
Revenues	Note 2. Revenues  Disaggregation of Revenue  We sell our products and services primarily in North America and in selected international markets. Revenue by geography is attributed based on the current billing address of the customer. The following table depicts the disaggregation of revenue by geographic region (in thousands):     Three Months Ended  March 31,  2019 2018  United States  Product sales $ 19,564 $ 13,577  Services 5,781 8,423  Total United States 25,345 22,000  Canada  Product sales 16,621 35,698  Services 8,375 11,477  Total Canada 24,996 47,175  Other Countries  Product sales 1,047 833  Services 1,462 678  Total Other Countries 2,509 1,511  Total  Product sales 37,232 50,108  Services 15,618 20,578  Total $ 52,850 $ 70,686  Contract Balances  When the timing of the delivery of products and provision of services is different from the timing of the customer payments, we recognize either a contract asset (performance precedes contractual due date in connection with estimates of variable consideration) or a contract liability (customer payment precedes performance) on our condensed consolidated balance sheet. The following table includes the contract assets and liabilities as of March 31, 2019 and January 1, 2019 (in thousands):     Contract Assets Contract Liabilities  Current Non-Current Current Non-Current  Balance at January 1, 2019 $ — $ — $ 515 $ —  Additions — — 68 —  Revenue recognized — — (515) —  Balance at March 31, 2019 $ — $ — $ 68 $ —  Our contract liability as of March 31, 2019 and January 1, 2019 is included in current liabilities on our condensed consolidated balance sheet. Our performance obligations for our product and service revenues are usually satisfied before the customer’s payment although prepayments may occasionally be required for international sales . Revenue recognized from the contract liability balance for the three months ended March 31, 2019 was $0.5 million. There was no revenue recognized from the contract liability balance for the three months ended March 31, 2018.  Practical Exemption  We do not disclose the value of unsatisfied performance obligations when the related contract has a duration of one year or less or we recognize revenue equal to what we have the right to invoice when that amount corresponds directly with the value to the customer of our performance to date.

Goodwill and Identifiable Intangibles [Abstract]
Goodwill and Identifiable Intangibles	Note 5. Goodwill and Identifiable Intangibles  Changes in the carrying amount of goodwill are as follows (in thousands):      At December 31, 2017 $ 184,478  Purchase price allocation adjustment 54  Impairments (154,003)  Currency translation adjustment (7,417)  At December 31, 2018 $ 23,112  Currency translation adjustment 24  At March 31, 2019 $ 23,136  We perform our annual impairment tests of goodwill as of December 31, or when there is an indication an impairment may have occurred. There was no impairment of goodwill during the three months ended March 31, 2019.  On December 31, 2018, we performed our annual impairment test for goodwill on each of our three reporting units. As a result of unfavorable oil and gas industry market conditions in late 2018 that continued to persist into early 2019 and the related impact on expected customer activity levels, particularly in Canada, as well as a decline in the quoted price of our common stock, we concluded that there had been an impairment because the carrying values exceeded the estimated fair values. We recorded impairment charges in the fourth quarter of 2018 in two reporting units, totaling $154.0 million. As a result of the impairment loss, we have no remaining goodwill in the fracturing systems and well construction reporting unit. Subsequent to the impairment charges, our goodwill was $23.1 million at March 31, 2019 and December 31, 2018, respectively.  Identifiable intangibles by major asset class consist of the following (in thousands) :      March 31, 2019  Estimated Gross  Useful Carrying Accumulated Net  Lives (Years) Amount Amortization Balance  Technology 8 - 18 $ 17,482 $ (986) $ 16,496  Trademarks 5 - 10 1,600 (253) 1,347  Customer relationships 10 - 21 28,608 (2,736) 25,872  Internally developed software 5 5,110 (256) 4,854  Total identifiable intangibles $ 52,800 $ (4,231) $ 48,569       December 31, 2018  Estimated Gross  Useful Carrying Accumulated Net  Lives (Years) Amount Amortization Balance  Technology 8 - 18 $ 17,289 $ (516) $ 16,773  Trademarks 5 - 10 1,600 (213) 1,387  Customer relationships 10 - 21 28,544 (2,339) 26,205  Internally developed software 5 4,620 — 4,620  Total identifiable intangibles $ 52,053 $ (3,068) $ 48,985 Identifiable intangibles with definite lives are tested for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. As a result of unfavorable oil and gas industry market conditions in late 2018 that continued to persist into early 2019 and the related impact on expected customer activity levels, particularly in Canada, as well as a decline in the quoted price of our common stock, we determined that the carrying values of certain intangible assets were no longer recoverable, which resulted in an impairment charge of $73.5 million in our asset group that includes fracturing systems and well construction, which we recorded in the fourth quarter of 2018.

Debt  Our long-term debt consists of the following as of March 31, 2019 and December 31, 2018 (in thousands):      March 31, December 31,  2019 2018  Prior Senior Secured Credit Facility $ 20,000 $ 20,000  Promissory note — —  Equipment notes 2,323 2,412  Finance leases 3,685 3,279  Total debt 26,008 25,691  Less: current portion (2,461) (2,236)  Long-term debt $ 23,547 $ 23,455  The estimated fair value of total debt for the periods ended March 31, 2019 and December 31, 2018 was $25.6 million and $25.3 million, respectively. The carrying value of the Prior Senior Secured Credit Facility and the lines of credit approximated the fair value of debt as they can be paid at any time. The fair value for the remaining debt was estimated using Level 2 inputs by calculating the sum of the discounted future interest and principal payments through the date of maturity .  Below is a description of our credit agreement and other financing arrangements.  Prior Senior Secured Credit Facility  On May 4, 2017, we entered into an Amended and Restated Credit Agreement (the “Prior Credit Agreement”) with Pioneer Investment, Inc., as borrower (the “U.S. Borrower ”), NCS Multistage Inc., as borrower (the “Canadian Borrower”), Pioneer Intermediate, Inc. (together with the Company, the “Parent Guarantors”) and the lenders party thereto, Wells Fargo Bank, National Association as administrative agent in respect of the U.S. Facility (as defined below) and Wells Fargo Bank, National Association, Canadian Branch, as administrative agent in respect of the Canadian Facility (as defined below) (the senior secured revolving credit facilities provided thereunder, the “Prior Senior Secured Credit Facility”). The Prior Credit Agreement amended and restated the previous credit agreement in its entirety. The Prior Senior Secured Credit Facility matures on May 4, 2020 .  The Prior Senior Secured Credit Facility originally consisted of a (i) senior secured revolving credit facility in an aggregate principal amount of $25.0 million made available to the U.S. Borrower (the “Prior U.S. Facility”), of which up to $5.0 million could be made available for letters of credit and up to $5.0 million may be made available for swingline loans and (ii) senior secured revolving credit facility in an aggregate principal amount of $25.0 million that could be made available to the Canadian Borrower (the “Prior Canadian Facility”).  We entered into Amendment No. 1 to the Prior Credit Agreement on August 31, 2017, which increased the loan commitment available to the U.S. Borrower to $50.0 million from $25.0 million under the Prior U.S. Facility. The loan commitment available under the Prior Canadian Facility remained at $25.0 million. On February 16, 2018 and October 9, 2018 , we entered into Amendments No. 2 and No. 3, respectively, to the Prior Credit Agreement, which amended certain negative covenants contained in the Prior Credit Agreement. As of March 31, 2019 and December 31, 2018 , we had $20.0 million in outstanding indebtedness under the Prior U.S. Facility and no outstanding indebtedness under the Prior Canadian Facility.  We incurred interest expense related to the Prior Senior Secured Credit Facility, including commitment fees, of $0. 3 million for each of the three months ended March 31, 2019 and 2018, respectively.  Borrowings under the Prior U.S. Facility may be made in U.S. dollars, Canadian dollars or Euros and bear interest at a rate equal to the Adjusted Base Rate or Eurocurrency Rate (each as defined in the Prior Credit Agreement), in each case, plus an applicable interest margin as set forth in the Prior Credit Agreement. Borrowings under the Prior Canadian Facility may be made in U.S. dollars or Canadian dollars and bear interest at the Canadian (Cdn) Base Rate, Canadian (U.S.) Base Rate, Eurocurrency Rate or Discount Rate (each as defined in the Prior Credit Agreement), in each case, plus an applicable interest margin as set forth in the Prior Credit Agreement. The Adjusted Base Rate, Canadian (U.S.) Base Rate and Canadian (Cdn) Base Rate applicable margin could be between 2.25% and 3.00% and the Eurocurrency Rate applicable margin could be between 3.25% and 4.00% , in each case, depending on the Company’s leverage ratio. The applicable interest rate at March 31, 2019 was 6.00% .  The obligations of the U.S. Borrower under the Prior U.S. Facility are guaranteed by the Parent Guarantors and each of the other existing and future direct and indirect restricted subsidiaries of the Company organized under the laws of the United States (subject to certain exceptions) and are secured by substantially all of the assets of the Parent Guarantors, the U.S. Borrower and such other subsidiary guarantors, in each case, subject to certain exceptions and permitted liens. The obligations of the Canadian Borrower under the Prior Canadian Facility are guaranteed by the Parent Guarantors, the U.S. Borrower and each of the future direct and indirect restricted subsidiaries of the Company organized under the laws of the United States and Canada (subject to certain exceptions) and are secured by substantially all of the assets of the Parent Guarantors, the U.S. Borrower, the Canadian Borrower and such subsidiary guarantors, in each case, subject to certain exceptions and permitted liens.  The Prior Credit Agreement contains financial covenants that require (i) commencing with the fiscal quarter ending June 30, 2017, compliance with a leverage ratio test set at (A) 3.00 to 1.00 as of the last day of each fiscal quarter ending prior to March 31, 2018 and (B) 2.50 to 1.00 as of the last day of each fiscal quarter ending on or after March 31, 2018, (ii) commencing with the fiscal quarter ending June 30, 2017, compliance with an interest coverage ratio test set at 2.75 to 1.00 as of the last day of each fiscal quarter, (iii) if the leverage ratio as of the end of any fiscal quarter is greater than 2.00 to 1.00 and the amount outstanding under the Prior Canadian Facility at any time during such fiscal quarter was greater than $0, compliance as of the end of such fiscal quarter with a Canadian asset coverage ratio test set at 1.00 to 1.00 and (iv) if the leverage ratio as of the end of any fiscal quarter is greater than 2.00 to 1.00 and the amount outstanding under the Prior U.S. Facility at any time during such fiscal quarter was greater than $0, compliance as of the end of such fiscal quarter with a U.S. asset coverage ratio test set at 1.00 to 1.00. As of March 31, 2019 , we were in compliance with these financial covenants. The Prior Credit Agreement also contains customary affirmative and negative covenants, including, among other things, restrictions on the creation of liens, the incurrence of indebtedness, investments, dividends and other restricted payments, dispositions and transactions with affiliates. The Prior Credit Agreement also includes customary events of default for facilities of this type (with customary grace periods, as applicable). If an event of default occurs, the lenders under each of the Prior U.S. Facility and the Prior Canadian Facility could elect (after the expiration of any applicable notice or grace periods) to declare all outstanding borrowings under such facility, together with accrued and unpaid interest and other amounts payable thereunder, to be immediately due and payable. The lenders under each of the Prior U.S. Facility and the Prior Canadian Facility also have the right upon an event of default thereunder to terminate any commitments they have to provide further borrowings under such facility. Further, following an event of default under each of the Prior U.S. Facility and the Prior Canadian Facility, the lenders thereunder will have the right to proceed against the collateral granted to them to secure such facility.  Direct costs of $1.0 million were incurred in connection with the Prior Senior Secured Credit Facility. The costs were capitalized as an asset as they represent the benefit of being able to access capital over the contractual term. The costs are being amortized over the term of the Prior Senior Secured Credit Facility using the straight-line method . Amortization expense of the deferred financing charges of $0.1 million was included in interest expense, net for each of the three months ended March 31, 2019 and 2018 , respectively.  On May 1, 2019, we entered into a new Second Amended and Restated Credit Agreement (the “New Credit Agreement”) amending and restating the Prior Credit Agreement. See “Note 14. Subsequent Events”.  Promissory Note  On February 27, 2017, Repeat Precision, LLC (“Repeat Precision”) entered into a promissory note with Security State Bank & Trust, Fredericksburg, for an aggregate borrowing capacity of $3.8 million. It bears interest at a variable interest rate based on prime plus 1.00% . The promissory note is secured against equipment, inventory and receivables. The promissory note was renewed on February 16, 2018 for an aggregate borrowing capacity of $4.3 million and was renewed again on February 15, 2019. The note is s cheduled to mature on February 16, 20 20. No other terms were changed. As of March 31, 2019 and December 31, 2018 , we had no outstanding indebtedness under the promissory note.  Equipment Notes  In February 2017, Repeat Precision entered into an equipment note in the amount of $0.8 million with Security State Bank & Trust, Fredericksburg. The equipment note bears interest at prime plus 1.00% , matures on February 27, 2021 and is collateralized by certain property. As of March 31, 2019 , the equipment note was paid in full and we had no outstanding indebtedness. As of December 31, 2018 , the outstanding balance on the equipment note was $0. 4 million.  In September 2018, Repeat Precision entered into an equipment note for an aggregate borrowing capacity of $3.8 million with Security State Bank & Trust, Fredericksburg. The equipment note bears interest at prime plus 1.00% , matures on June 7, 2023 and is collateralized by certain property. As of March 31, 2019 and December 31, 2018 , the outstanding balance on the equipment note was $2.3 million and $2.0 million, respectively .

Leases [Abstract]
Leases	Note 8. Leases  We determine if a contract contains a lease at the inception of an arrangement. If so, ROU assets representing the right to use an underlying asset for the lease term and lease liabilities representing an obligation to make lease payments arising from the lease are included on the condensed consolidated balance sheet.  We have operating and finance leases for facilities, vehicles, and equipment. Some leases include one or more options to renew, with renewal terms that can extend the lease term from five to ten years with exercise of lease renewal options being at the sole discretion of NCS as lessee. Certain leases also include options to purchase the leased property. Some leases may include an option to terminate the contract with notice. ROU assets and lease liabilities with a term of longer than 12 months are recognized at the lease commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, our interest rate under the s enior s ecured c redit f acility is used as an incremental borrowing rate applied to the present value calculation at the lease commencement date unless the implicit rate is readily determinable. Lease expense for operating leases is recognized on a straight-line basis over the lease term. At adoption, ROU assets included any lease payments already made and excluded any initial direct costs.  Our lease agreements are from a lessee perspective and do not contain (i) any leases with variable lease payments (e.g., payments that depend on a percentage of sales of a lessee or payments that increase based upon an index such as a consumer price index), (ii) residual value guarantees probable of being paid or (iii) material restrictive covenants. Lease agreements with lease and non-lease components are generally accounted for separately when practical. For leases where the lease and non-lease component are comingled and the non-lease component is determined to be insignificant when compared to the lease component, the lease and non-lease components are treated as a single lease component for all asset classes.  As of March 31, 2019, we do not have any lessor leases and we do not have any additional operating and finance leases that have not yet commenced.  Supplemental balance sheet information related to leases are as follows (in thousands):     March 31,  Leases Condensed Consolidated Balance Sheet Location 2019  Assets  Operating lease right-of-use assets Deposits and other assets $ 6,938  Finance lease right-of-use assets (1) Property and equipment, net 4,234  Total leased right-of-use assets $ 11,172   Liabilities  Current  Operating lease liabilities Other current liabilities $ 2,711  Finance lease liabilities Current maturities of long-term debt 1,758   Noncurrent  Operating lease liabilities Other long-term liabilities 4,263  Finance lease liabilities Long-term debt, less current maturities 1,927  Total lease liabilities $ 10,659 _______________ (1) Finance lease right-of-use assets are recorded net of accumulated amortization of $1.6 million as of March 31, 2019 .

Commitments and Contingencies [Abstract]
Commitments and Contingencies	Note 9. Commitments and Contingencies  Litigation  In the ordinary course of our business, from time to time, we have various claims, lawsuits and administrative proceedings that are pending or threatened with respect to commercial, intellectual property and employee matters.  On July 24, 2018, we filed a patent infringement lawsuit against Kobold Corporation, Kobold Completions Inc. and 2039974 Alberta Ltd. (“Kobold”) in the Federal Court of Canada, alleging that Kobold’s fracturing tools and methods infringe on several of our Canadian patents. We previously filed a breach of contract lawsuit on March 16, 2018, against Kobold Corporation in the Court of Queen’s Bench of Alberta, alleging breach of a prior settlement agreement. Both of these lawsuit s seek unspecified monetary damages and injunctive relief.  In early February 2019, we filed a lawsuit against Diamondback Industries, Inc. (“Diamondback”) in the United States District Court for the Western District of Texas, Waco Division, alleging patent infringement, breach of contract and related claims stemming from Diamondback’s breach of an exclusive license, granted by Diamondback to Repeat Precision, to a patent necessary for the manufacture and sale of a disposable setting tool. Around the same time, Diamondback filed a lawsuit against Repeat Precision and various NCS entities in an effort to invalidate the exclusive license agreement and requested monetary damages. We believe the exclusive license is enforceable and there is no basis to support the claims asserted by Diamondback and we intend to vigorously enforce our rights under the license agreement.  In accordance with GAAP, we accrue for contingencies where the occurrence of a material loss is probable and can be reasonably estimated, based on our estimate of the expected liability. If we have any outstanding legal accruals, we may increase or decrease these in the future, on a matter-by-matter basis, to account for developments. Our assessment of the likely outcome of litigation matters is based on our judgment of a number of factors, including experience with similar matters, past history, precedents, relevant financial information and other evidence and facts specific to the matter. While the outcome of any legal proceedings cannot be predicted with any certainty, based on a consideration of relevant facts and circumstances, our management currently does not expect that the results of these legal proceedings would have a material adverse effect on our financial position, results of operations or cash flows.

Share-Based Compensation [Abstract]
Share-Based Compensation	Note 10. Share- Based Compensation  During the first quarter of 2019, we granted 918,155 equity-classified restricted stock units (“RSUs”) with a weighted average grant date fair value of $5.51 . Of the RSUs granted, 799,317 RSUs will vest and settle ratably in three equal annual installments beginning on the anniversary of the date of grant and 118,838 RSUs, which were granted to the nonemployee members of the Board of Directors, will vest on the one year anniversary of the grant date. T he RSUs for the members of the Board of Directors either settle at vesting or, if the director has elected to defer the RSUs, within thirty days following the earlier of the termination of the director’s service for any reason or a change of control.  During the first quarter of 2019, we granted 610,570 equivalent stock units, or cash-settled, liability-classified RSUs (“ESUs”), with a weighted average grant date fair value of $5.51 , which will vest and settle ratably in three equal annual installments beginning on the anniversary of the date of grant. The ESUs will be settled in cash and the cash settled for any ESU will not exceed two times the fair market value of our common stock as of the day before the grant date. Compensation cost is remeasured each reporting period at fair value based upon the closing stock price of our common stock until the awards are settled.  In addition, during the first quarter of 2019, we granted 377,334 performance stock unit awards (“PSUs”), which have a performance period from January 1, 2019 to December 31, 2021. The grant date fair value of the PSUs of $6.50 was measured using a Monte Carlo simulation. The number of PSUs ultimately issued under the program is dependent upon our total shareholder return relative to our performance peer group (“relative TSR”) over the three -year performance period. Each PSU will settle for between zero and two shares of our common stock in the first quarter of 2021. The threshold performance level (25th percentile relative TSR) starts to earn PSUs, the mid-point performance level (50th percentile relative TSR) earns 65% of the target PSUs and the maximum performance level (90th percentile relative TSR) or greater earns 200% of the target PSUs.  The total share-based compensation expense for all awards was $3.1 million and $2.4 million for the three months ended March 31, 2019 and 2018 , respectively. 

Income Taxes

Income Taxes [Abstract]
Income Taxes	Note 11. Income Taxes  The computation of the annual expected effective tax rate at each interim period requires certain estimates and assumptions including , but not limited to, the expected operating income (or loss) for the year, projections of the proportion of income (or loss) earned and taxed in foreign jurisdictions, permanent and temporary differences and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, more experience is acquired or additional information is obtained. The computation of the annual effective rate would include applicable modifications, which were projected for the year, such as certain book expenses not deductible for tax, tax credits and foreign deemed dividends.  We recorded a tax expense of $9.6 million and $0.9 million for the three months ended March 31, 2019 and 2018 , respectively. Included in tax expense for the three months ended March 31, 2019 was a valuation allowance in the amount of $9.8 million against our U.S. deferred tax asset based on management’s position that the Company has not met the more likely than not condition of realizing the deferred tax asset based on the existence of sufficient projected U.S. taxable income of the appropriate character to recognize the tax benefit . Without the valuation allowance, the net income tax benefit is approximately $0.2 million. For the three months ended March 31, 2018, our effective tax rate was 7.4% . The income tax expense and effective tax rate for the three months ended March 31, 2018 was significantly impacted by the U.S. Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act ”) including administrative guidance issued by the Internal Revenue Service on April 2, 2018. This guidance along with other updates resulted in a change to the calculation of the mandatory one-time tax on accumulated earnings of foreign subsidiaries in 2017 and a tax benefit of $2.1 million for the three months ended March 31, 2018 was recorded in tax expense with a corresponding reduction in the effective tax rate of 16.4 % . Additionally, the effective tax rate for the three months ended March 31, 2019 and 2018 included a tax expense (benefit) of $0.3 million and $(0.3) million, respectively, for the tax effect of stock awards.  The 2017 Tax Act was signed into law on December 22, 2017. The 2017 Tax Act significantly revised the U.S. corporate income tax by, among other things, lowering the statutory corporate tax rate from 35% to 21% , eliminating certain deductions, imposing a mandatory one-time tax on accumulated earnings of foreign subsidiaries as of 2017, introducing new tax regimes, and changing how foreign earnings are subject to U.S. tax. Our preliminary estimate of the 2017 Tax Act and the remeasurement of our deferred tax assets and liabilities is subject to the finalization of management’s analysis related to certain matters, such as developing interpretations of the provisions of the 2017 Tax Act, changes to certain estimates and the filing of our tax returns. U.S. Treasury regulations, administrative interpretations or court decisions interpreting the 2017 Tax Act may require further adjustments and changes in our estimates. Those adjustments may impact our provision for income taxes in the period in which the adjustments are made.  For our calendar year beginning in 2018 we are subject to several provisions of the 2017 Tax Act including computations under Global Intangible Low Taxed Income (“GILTI”) and Foreign Derived Intangible Income (“FDII”). We were able to make a reasonable estimate of the impact of each provision of the 2017 Tax Act on our effective tax rate for the three months ended March 31, 2019 and 2018.  ASC 740 clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. The impact of an uncertain income tax position on the income tax returns must be recognized at the largest amount that is more-likely-than-not to be required to be recognized upon audit by the relevant taxing authority. This standard also provides guidance on de-recognition, measurement, classification, interest and penalties, accounting for interim periods, disclosure and transition issues with respect to tax positions. We include interest and penalties as a component of other income, net in the condensed consolidated statements of operations and recognized $26 thousand for the three months ended March 31, 2019 . There was no interest and penalties for the three months ended March 31, 2018.

The New Credit Agreement amended and restated the Prior Credit Agreement in its entirety.  The New Senior Secured Credit Facility consists of a (i) senior secured revolving credit facility in an aggregate principal amount of $50.0 million made available to the U.S. Borrower (the “New U.S. Facility”), of which up to $5.0 million may be made available for letters of credit and up to $5.0 million may be made available for swingline loans and (ii) senior secured revolving credit facility in an aggregate principal amount of $25.0 million made available to the Canadian Borrower (the “New Canadian Facility”). The New Senior Secured Credit Facility will mature on May 1, 2023.  Borrowings under the New U.S. Facility may be made in U.S. dollars for Adjusted Base Rate Advances, and in U.S. dollars, Canadian dollars or Euros for Eurocurrency Rate Advances (each as defined in the New Credit Agreement). Such advances bear interest at the Adjusted Base Rate or at the Eurocurrency Rate plus an applicable interest margin as set forth in the New Credit Agreement. Borrowings under the New Canadian Facility may be made in U.S. dollars or Canadian dollars and bear interest at the Canadian (Cdn) Base Rate, Canadian (U.S.) Base Rate, Eurocurrency Rate or Discount Rate (each as defined in the New Credit Agreement), in each case, plus an applicable interest margin as set forth in the New Credit Agreement.  The obligations of the U.S. Borrower under the New U.S. Facility are guaranteed by the Parent Guarantors and each of the other existing and future direct and indirect restricted subsidiaries of the Company organized under the laws of the United States (subject to certain exceptions) and are secured by substantially all of the assets of the Parent Guarantors, the U.S. Borrower and such other subsidiary guarantors, in each case, subject to certain exceptions and permitted liens. The obligations of the Canadian Borrower under the New Canadian Facility are guaranteed by the Parent Guarantors, the U.S. Borrower and each of the other future direct and indirect restricted subsidiaries of the Company organized under the laws of the United States and Canada (subject to certain exceptions) and are secured by substantially all of the assets of the Parent Guarantors, the U.S. Borrower, the Canadian Borrower and such other subsidiary guarantors, in each case, subject to certain exceptions and permitted liens.  The New Credit Agreement contains financial covenants that require (i) commencing with the fiscal quarter ending June 30, 2019, compliance with a maximum leverage ratio test set at 2.50 to 1.00 as of the last day of each fiscal quarter, (ii) commencing with the fiscal quarter ending June 30, 2019, compliance with an interest coverage ratio test set at not more than 2.75 to 1.00 as of the last day of each fiscal quarter, (iii) if the leverage ratio as of the end of any fiscal quarter is greater than 2.00 to 1.00 and the amount outstanding under the New Canadian Facility at any time during such fiscal quarter was greater than $0, compliance as of the end of such fiscal quarter with a Canadian asset coverage ratio test of at least 1.00 to 1.00 and (iv) if the leverage ratio as of the end of any fiscal quarter is greater than 2.00 to 1.00 and the amount outstanding under the New U.S. Facility at any time during such fiscal quarter was greater than $0, compliance as of the end of such fiscal quarter with a U.S. asset coverage ratio test of at least 1.00 to 1.00. The New Credit Agreement also contains customary affirmative and negative covenants, including, among other things, restrictions on the creation of liens, the incurrence of indebtedness, investments, dividends and other restricted payments, dispositions and transactions with affiliates. The New Credit Agreement also includes customary events of default for facilities of this type (with customary grace periods, as applicable). If an event of default occurs, the lenders under each of the New U.S. Facility and the New Canadian Facility may elect (after the expiration of any applicable notice or grace periods) to declare all outstanding borrowings under such facility, together with accrued and unpaid interest and other amounts payable thereunder, to be immediately due and payable. The lenders under each of the New U.S. Facility and the New Canadian Facility also have the right upon an event of default thereunder to terminate any commitments they have to provide further borrowings under such facility. Further, following an event of default under each of the New U.S. Facility and the New Canadian Facility, the lenders thereunder will have the right to proceed against the collateral granted to them to secure such facility.

We operate through service facilities principally located in Houston, Midland and Corpus Christi, Texas; Tulsa and Oklahoma City, Oklahoma; Billings, Montana; Morgantown, West Virginia; Calgary, Red Deer, Grande Prairie and Estevan, Canada; Neuquen, Argentina and Stavanger, Norway.
Basis of Presentation	Basis of Presentation  Our accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), issued by the Securities Exchange Commission (“SEC”) and have not been audited by our independent registered public accounting firm. The Condensed Consolidated Balance Sheet at December 31, 2018 is derived from our audited financial statements. However, certain information and footnote disclosures required by GAAP for complete annual financial statements have been omitted or condensed as permitted by the rules and regulations of the SEC, and, therefore, these interim financial statements should be read in conjunction with our audited financial statements included in our Annual Report on Form 10-K filed with the SEC on March 8, 2019. 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. All intercompany accounts and transactions have been eliminated for purposes of preparing these condensed consolidated financial statements.
Inventories	Inventories  Inventories consist primarily of raw material, product components, assembled products, certain components used to internally construct our frac isolation assemblies and chemicals, in raw material or finished goods, used in our tracer diagnostics services. Inventories are stated at the lower of cost or estimated net realizable value. Cost is determined at standard costs approximating the first-in first-out basis. We continuously evaluate inventories, based on an analysis of inventory levels, historical sales experience and future sales forecasts, to determine obsolete, slow-moving and excess inventory. Adjustments to reduce such inventory to its estimated recoverable value have been recorded as an adjustment to cost of sales.
Recent Accounting Pronouncements	Recent Accounting Pronouncements  Pronouncement Adopted in 2019  In February 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) , which requires lessees to recognize a right-of-use (“ROU”) asset and a lease liability for all leases with terms longer than 12 months. Under the new standard, lessees need to recognize leases on their balance sheets as lease liabilities with corresponding ROU assets. We adopted the standard effective January 1, 2019, using a modified retrospective transition method and applying certain optional practical expedients. NCS elected an optional transition method that allowed application of the new standard at the adoption date and the recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption with no adjustment to previously reported results. We also elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed the carry forward of historical lease classification as well as additional practical expedients related to land easements, short-term leases, and non-lease components. We did not elect the practical expedient related to hindsight. The standard had a material impact on our condensed consolidated balance sheet but did not materially impact our condensed consolidated statements of operations or condensed consolidated statements of cash flows. Adoption of the new standard resulted in the recording of ROU assets and lease liabilities of $7.5 million on January 1, 2019. See “Note 8. Leases” for more information. Pronouncements Not Yet Effective  In August 2018, the FASB issued ASU No. 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40) . The ASU aligns the requirements to capitalize implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements to capitalize implementation costs incurred to develop or obtain internal-use software. For public entities, this guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. We are currently evaluating the impact of the adoption of this guidance.  In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) . The ASU modifies, removes and adds certain disclosure requirements on fair value measurements. For public entities, this guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted for all amendments. Further, entities may early adopt eliminated or modified disclosure requirements and delay the adoption of all new disclosure requirements until the effective date. We are currently evaluating the impact of the adoption of this guidance.
