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; Neuquén, 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 but do not currently expect that the adoption of this guidance will have a material impact on our consolidated financial statements.  In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326). This ASU introduces a new impairment model that is based on expected credit losses rather than incurred credit losses for financial instruments, including trade accounts receivable. It requires an entity to measure expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The new standard is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. On October 16, 2019, the FASB affirmed its decision on amendments to the effective dates for certain ASUs. The effective date for ASU 2016-13 will remain the same for public business entities that are SEC filers, excluding entities eligible to be small reporting companies (“SRC”). The effective date for all other entities, including SRCs, will begin after December 15, 2022, including interim periods within those fiscal years. The FASB expects the final ASU on effective dates will be issued in mid-November 2019. We are currently evaluating the impact of the adoption of this guidance.

We currently do not have any contract assets. The following table includes the contract liabilities as of September 30, 2019 and December 31, 2018 (in thousands):     Contract Liabilities  Current Non-Current  Balance at December 31, 2018 $ 515 $ —  Additions 99 —  Revenue recognized (560) —  Balance at September 30, 2019 $ 54 $ —  Our contract liability as of September 30, 2019 and December 31, 2018 is included in current liabilities on our condensed consolidated balance sheet. Our performance obligations for our product and service revenues are satisfied before the customer’s payment however prepayments may occasionally be required for international sales . Revenue recognized from the contract liability balance was $31 thousand and $0.1 million for the three months ended September 30, 2019 and 2018 , respectively, and $0.6 million and $0.2 million for the nine months ended September 30, 2019 and 2018 , respectively.  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):      Gross Value Accumulated Impairment Net  At December 31, 2017 $ 184,478 $ — $ 184,478  Purchase price allocation adjustment 54 — 54  Impairment — (154,003) (154,003)  Currency translation adjustment (7,417) — (7,417)  At December 31, 2018 $ 177,115 $ (154,003) $ 23,112  Impairment — (7,937) (7,937)  Currency translation adjustment 47 — 47  At September 30, 2019 $ 177,162 $ (161,940) $ 15,222  We perform our annual impairment tests of goodwill as of December 31, or when there is an indication an impairment may have occurred.  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 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.  During the second quarter of 2019, we performed an impairment test for goodwill and determined that the carrying value of one of our reporting units exceeded its fair value. We recorded an impairment charge of $ 7.9 million for our tracer diagnostic services reporting unit as a result of a further deterioration in customer activity levels in North America. This resulted in lower demand for oilfield services driving a decrease in our market share and increased customer and competitor-driven pricing pressures in addition to a decline in the quoted price of our common stock. Following the impairment, our tracer diagnostic services reporting unit has no remaining goodwill balance.  There was no impairment recorded at any reporting unit for the three months ended September 30, 2019, and no impairment recorded in any other reporting unit for the nine months ended September 30, 2019.  Identifiable intangibles by major asset class consist of the following (in thousands) :      September 30, 2019  Estimated Gross  Useful Carrying Accumulated Net  Lives (Years) Amount Amortization Balance  Technology 8 - 18 $ 17,559 $ (1,933) $ 15,626  Trademarks 5 - 10 1,600 (333) 1,267  Customer relationships 10 - 21 28,634 (3,527) 25,107  Internally developed software 5 4,881 (735) 4,146  Total identifiable intangibles $ 52,674 $ (6,528) $ 46,146      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 Total amortization expense, which is associated with the s elling, general and administrative expenses income statement line item, was $1.2 million and $3.3 million for the three months ended September 30, 2019 and 2018 , respectively, and $3.5 million and $9.9 million for the nine months ended September 30, 2019 and 2018 , respectively.  Identifiable intangibles with definite lives are tested for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. On December 31, 2018, 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. There were no impairments recorded for our identifiable intangibles for the three and nine months ended September 30, 2019 .

The carrying value of the senior secured revolving 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 prior and new credit agreements and other financing arrangements.  Prior Senior Secured Credit Facility  On May 4, 2017, we entered into a credit agreement (the “Prior Credit Agreement”) with a group of financial institutions which originally consisted of a (i) senior secured revolving credit facility (the “Prior U.S. Facility”) in an aggregate principal amount of $25.0 million made available to Pioneer Investment, Inc. (the “U.S. Borrower”), of which up to $5.0 million was available for letters of credit and up to $5.0 million was available for swingline loans and (ii) senior secured revolving credit facility (the “Prior Canadian Facility”) (together, the “Prior Senior Secured Credit Facility”) in an aggregate principal amount of $25.0 million made available to NCS Multistage Inc. (the “Canadian Borrower”) .  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 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.  Borrowings under the Prior U.S. Facility were available in U.S. dollars, Canadian dollars or Euros and had an interest 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 were available in U.S. dollars or Canadian dollars and accrued 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 have been between 2.25% and 3.00% and the Eurocurrency Rate applicable margin could have been between 3.25% and 4.00% , in each case, depending on the Company’s leverage ratio.  We incurred interest expense related to the Prior Senior Secured Credit Facility, including commitment fees, of $ 0.5 million and $0.9 million for the nine months ended September 30, 2019 and 2018 , respectively.  The obligations of the U.S. Borrower under the Prior U.S. Facility were guaranteed by Pioneer Intermediate, Inc. and the Company (together, 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 were 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 were 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 were 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.  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 represented the benefit of being able to access capital over the contractual term. The costs were amortized over the term of the Prior Senior Secured Credit Facility using the straight-line method. As a result of our New Credit Agreement (as defined below), which was a modification of our revolving credit facility, unamortized deferred costs of $0.3 million related to the Prior Senior Secured Credit Facility were deferred and are being amortized over the term of the new arrangement.  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.  New Senior Secured Credit Facility  On May 1, 2019, we entered into the New Credit Agreement with Pioneer Investment, Inc., as U.S. borrower, NCS Multistage Inc., as Canadian borrower, Pioneer Intermediate, Inc. and the lenders party thereto, Wells Fargo Bank, National Association as administrative agent in respect of the New U.S. Facility (as defined below) and Wells Fargo Bank, National Association, Canadian Branch, as administrative agent in respect of the New Canadian Facility (as defined below) (the senior secured revolving credit facilities provided thereunder, the “New Senior Secured Credit Facility”). 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. As of September 30, 2019 , we had $13.0 million in outstanding indebtedness under the New U.S. Facility and no outstanding indebtedness under the New Canadian Facility.  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 applicable interest rate at September 30, 2019 was 5.125% . We incurred interest expense related to the New Senior Secured Credit Facility, including commitment fees, of $0.3 million and $0.5 million for the three and nine months ended September 30, 2019 , respectively.  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. As of September 30, 2019 , we were in compliance with these financial covenants. 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  Direct costs of $0.9 million were incurred in connection with the New 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. Additionally, $0.3 million of unamortized deferred costs related to the Prior Senior Secured Credit Facility are also being amortized over the term of the New 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 the three and nine months ended September 30, 2019 .  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 September 30, 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. During the first quarter of 2019, the equipment note was paid in full and we had no outstanding indebtedness under the equipment note a s of September 30, 2019 . 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.

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 secured credit facility 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.

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. On July 12, 2019, Kobold filed a counterclaim seeking unspecified damages alleging that our fracturing tools and methods infringe on their patent and that we made false and misleading statements about Kobold.  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 proceeding 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

Share-Based Compensation [Abstract]
Share-Based Compensation	Note 10. Share- Based Compensation  During the nine months ended September 30, 2019 , we granted 1,030,216 equity-classified restricted stock units (“RSUs”) with a weighted average grant date fair value of $5.28 . Of the RSUs granted, 842,236 RSUs will vest and settle ratably in three equal annual installments beginning on the anniversary of the date of grant and 187,980 RSUs, which were granted to the nonemployee members of the Board of Directors, will generally 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 nine months ended September 30, 2019 , we granted 625,488 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 nine months ended September 30, 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.  Our Employee Stock Purchase Plan for U.S. Employees and our Employee Stock Purchase Plan for non-U.S. Employees (together, the “ESPP”) allows eligible employees to purchase shares of our common stock at a discounted price. In July 2019, we issued 115,19 2 shares of our common stock to our employees in connection with the settlement of the purchase of shares for the January 1, 2019 to June 30, 2019 offering period, which increased our common stock outstanding. The ESPP was temporarily suspended for future offering periods beginning on July 1, 2019.  The total share-based compensation expense for all awards was $2.9 million for each of the three months ended September 30, 2019 and 2018 and $9.4 million and $8.2 million for the nine months ended September 30, 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 (benefit) expense of $(1.4) million and $3.2 million for the three months ended September 30, 2019 and 2018 , respectively. For the nine months ended September 30, 2019 and 2018 , we recorded a tax expense of $10.2 million and $3.1 million, respectively. Included in tax expense for the nine months ended September 30, 2019 was a valuation allowance against our U.S. deferred tax asset based on management’s position that we have 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 as well as the tax effect of a non-deductible goodwill impairment. These adjustments resulted in additional tax (benefit) expense for the three and nine months ended September 30, 2019 of approximately $(6.9) million and $11.7 million, respectively . For the three and nine months ended September 30, 2018 , our effective rates were 29.3% and 15.7% , respectively. The income tax expense and effective tax rates for the three and nine months ended September 30, 2018 were 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 expense (benefit) of approximately $0.5 million and $(2.1) million for the three and nine months ended September 30, 2018 , respectively. Additionally, the effective tax rate for the nine months ended September 30, 2019 and 2018 included a tax expense (benefit) of $0.4 million and $(0. 4 ) 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 and nine months ended September 30, 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 (expense), net in the condensed consolidated statements of operations and recognized $42 thousand and $58 thousand for the nine months ended September 30, 2019 and 2018, respectively.

Basis of Presentation [Abstract]
Nature of Business	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; Neuquén, 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 but do not currently expect that the adoption of this guidance will have a material impact on our consolidated financial statements.  In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326). This ASU introduces a new impairment model that is based on expected credit losses rather than incurred credit losses for financial instruments, including trade accounts receivable. It requires an entity to measure expected credit losses for financial assets held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. The new standard is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. On October 16, 2019, the FASB affirmed its decision on amendments to the effective dates for certain ASUs. The effective date for ASU 2016-13 will remain the same for public business entities that are SEC filers, excluding entities eligible to be small reporting companies (“SRC”). The effective date for all other entities, including SRCs, will begin after December 15, 2022, including interim periods within those fiscal years. The FASB expects the final ASU on effective dates will be issued in mid-November 2019. We are currently evaluating the impact of the adoption of this guidance.
