Organization Consolidation And Presentation Of Financial Statements [Abstract]
Company and Organization	1. Company and Organization Company Description Nine Energy Service, Inc. (the “Company” or “Nine”), a Delaware corporation, is an oilfield services business that provides services integral to the completion of unconventional wells through a full range of tools and methodologies and provides a range of production enhancement and well workover services. The Company is headquartered in Houston, Texas. Magnum Acquisition On October 25, 2018, pursuant to the terms of a Securities Purchase Agreement, dated October 15, 2018 (the “Magnum Purchase Agreement”), the Company acquired all of the equity interests of Magnum Oil Tools International, LTD, Magnum Oil Tools GP, LLC and Magnum Oil Tools Canada Ltd. (such entities collectively, “Magnum” and such acquisition, the “Magnum Acquisition”) for approximately $334.5 million in upfront cash consideration, subject to customary adjustments, and 5.0 million shares of the Company’s common stock, which were issued to the sellers of Magnum in a private placement. The Magnum Purchase Agreement also includes the potential for additional future payments in cash of (i) up to 60% of net income (before interest, taxes and certain gains or losses) for the “E-Set” tools business in 2019 through 2025 and (ii) up to $25.0 million based on sales of certain dissolvable plug products in 2019. Due to the timing of the closing of the acquisition, the Company has not completed the detailed valuation work necessary to determine the required estimates of the fair value of the acquired assets and liabilities assumed and the related allocation of purchase price. The Company’s preliminary allocation of purchase price to the assets acquired will be included in the Company’s future filings. Initial Public Offering In January 2018, the Company completed its initial public offering (“IPO”) of 8,050,000 shares of common stock (including 1,050,000 shares pursuant to an over-allotment option) at a price to the public of $23.00 per share pursuant to a registration statement on Form S-1 (File 333-217601), as amended and declared effective by the U.S. Securities and Exchange Commission (the “SEC”) Beckman Combination On February 28, 2017, pursuant to the terms and conditions of a combination agreement dated February 3, 2017, the Company merged with Beckman Production Services, Inc. (“Beckman”), and all of the issued and outstanding shares of Beckman common stock were converted into shares of common stock of Nine Energy Service, Inc. (the “Combination”). Prior to the Combination, SCF-VII, L.P. had controlled a majority of the voting interests of Nine and Beckman since February 28, 2011 and July 31, 2012, respectively. The merger of the entities into the combined company was accounted for using reorganization accounting (i.e., “as if” pooling of interest) for entities under common control. For additional information, see Note 4 – Acquisitions and Combinations.

Accounting Policies [Abstract]
Basis of Presentation	2. Basis of Presentation Condensed Consolidated Financial Information The accompanying Condensed Consolidated Financial Statements have not been audited by the Company’s independent registered public These Condensed Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the SEC for interim financial information. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statements. Therefore, these Condensed Consolidated Financial Statements should be read in conjunction with the Company’s audited Consolidated Financial Statements and notes thereto for the year ended December 31, 2017, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 filed with the SEC. The operating results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. Principles of Consolidation The Condensed Consolidated Financial Statements include the accounts of Nine and its wholly owned subsidiaries. All inter-company accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. These estimates are based on management’s best knowledge of current events and actions that the Company may undertake in the future. Such estimates include fair value assumptions used in purchase accounting and in analyzing goodwill, other intangibles and long-lived assets for possible impairment, useful lives used in depreciation and amortization expense, stock-based compensation fair value, estimated realizable value on excess and obsolete inventories, deferred taxes and income tax contingencies, and losses on accounts receivable. It is at least reasonably possible that the estimates used will change within the next year.

(“JP Morgan”) as administrative agent and certain other financial institutions that became effective upon the consummation of the IPO in January 2018 (the “Effective Date”). Pursuant to the terms of the 2018 IPO Credit Agreement, the Company and its domestic restricted subsidiaries were entitled to borrow $125.0 million of term loans (the “2018 IPO Term Loan Credit Facility”), which the Company drew in full on the Effective Date. In January 2018, the Company also made a mandatory prepayment of $9.7 million against the 2018 IPO Term Loan Credit Facility, which approximated 50.0% of the estimated net proceeds from the IPO in excess of $150.0 million, as prescribed under the 2018 IPO Credit Agreement. In addition, under the 2018 IPO Credit Agreement, the Company and its domestic restricted subsidiaries were entitled to borrow up to $50.0 million (including letters of credit) as revolving credit loans under the revolving commitments (the “2018 IPO Revolving Credit Facility”). At September 30, 2018, the 2018 IPO Revolving Credit Facility had an undrawn capacity of $49.5 million, which was net of a $0.5 million outstanding letter of credit. Concurrent with the effectiveness of the 2018 IPO Credit Agreement, using proceeds received from the IPO and borrowings under the 2018 IPO Term Loan Credit Facility, the Company repaid all indebtedness under its prior term loan and the Beckman term loan (together, the “Legacy Term Loans”) and under its prior revolving credit facility and the Beckman revolving credit facility (together, the “Legacy Revolving Credit Facilities”) in the first quarter of 2018, which approximated $242.2 million. In addition, in the first quarter of 2018, the Company wrote off approximately $0.7 million in deferred financing costs associated with the Legacy Term Loans and the Legacy Revolving Credit Facilities. All of the obligations under the 2018 IPO Credit Agreement were secured by first priority perfected security interests (subject to permitted liens) in substantially all of the personal property of the Company and its domestic restricted subsidiaries, excluding certain assets. Loans to the Company and its domestic restricted subsidiaries under the 2018 IPO Credit Agreement were either base rate loans or LIBOR loans. The applicable margin for base rate loans varied from 1.50% to 2.75%, and the applicable margin for LIBOR loans varied from 2.50% to 3.75%, in each case depending on the Company’s leverage ratio. Interest rates averaged 5.5% during the nine months ended September 30, 2018. The Company was permitted to repay any amounts borrowed prior to the maturity date without any premium or penalty other than customary LIBOR breakage costs. In addition, a commitment fee of 0.50% per annum was charged on the average daily unused portion of the revolving commitments. Such commitment fee was payable quarterly in arrears. The 2018 IPO Credit Agreement contained various affirmative and negative covenants, including financial reporting requirements and limitations on indebtedness, liens, mergers, consolidations, liquidations and dissolutions, sales of assets, dividends and other restricted payments, investments (including acquisitions), and transactions with affiliates. Financial covenants under the 2018 IPO Credit Agreement included a maximum total leverage ratio, an asset coverage ratio and a fixed charge coverage ratio, each of which was calculated on a quarterly basis. The Company was in compliance with all debt covenants under the 2018 IPO Credit Agreement as of September 30, 2018. The fair value of the Company’s debt obligations under the 2018 IPO Credit Agreement was classified within Level 2 of the fair value hierarchy. Fair value approximated carrying value, as the interest rates are variable and based on market rates. On October 25, 2018, the Company fully repaid and terminated the 2018 IPO Credit Agreement as more fully described below. Unamortized deferred financing costs associated with the Company’s 2018 IPO Term Loan Credit Facility were $1.2 million at September 30, 2018. These costs were being amortized through the maturity date of the 2018 IPO Term Loan Credit Facility using the effective interest method. The Company wrote off these deferred financing costs on October 25, 2018 in conjunction with the termination of the 2018 IPO Credit Agreement. Senior Notes On October 25, 2018, the Company issued $400.0 million principal amount of 8.750% Senior Notes due 2023 (the “Senior Notes”). The Senior Notes will bear interest at an annual rate of 8.750% payable on May 1 and November 1 of each year with the first interest payment being due on May 1, 2019. The proceeds from the Senior Notes, together with cash on hand and borrowings under the 2018 ABL Credit Facility (as defined below), were used to (i) fund a portion of the upfront cash purchase price of the Magnum Acquisition, (ii) repay all indebtedness under the 2018 IPO Credit Agreement and (iii) pay fees and expenses associated with the issuance of the Senior Notes, the Magnum Acquisition and the 2018 ABL Credit Facility. For additional information regarding the Magnum Acquisition, see Note 1 – Company and Organization. 2018 ABL Credit Facility On October 25, 2018, the Company entered into a five-year asset based senior secured revolving credit facility with JP Morgan serving as administrative agent for the lenders thereunder (the “2018 ABL Credit Facility”). The 2018 ABL Credit Facility permits aggregate borrowings of up to $200.0 million, subject to a borrowing base, including a Canadian tranche with a sub-limit of up to $25.0 million and a sub-limit of $50.0 million for letters of credit. The borrowing base is initially $146.5 million. Concurrent with the effectiveness of the 2018 ABL Credit Facility, the Company borrowed approximately $35.0 million to fund a portion of the upfront cash purchase price of the Magnum Acquisition. The 2018 ABL Credit Facility will mature on October 25, 2023 or, if earlier, on the date that is 180 days before the scheduled maturity date of the Senior Notes if they have not been redeemed or repurchased by such date.

Commitments And Contingencies Disclosure [Abstract]
Commitment and contingencies	9. Commitments and Contingencies Litigation From time to time, the Company has various claims, lawsuits, and administrative proceedings that are pending or threatened with respect to personal injury, workers’ compensation, contractual matters, and other matters. Although no assurance can be given with respect to the outcome of these and the effect such outcomes may have, the Company believes any ultimate liability resulting from the outcome of such claims, lawsuits, or administrative proceedings, to the extent not otherwise provided for or covered by insurance, will not have a material adverse effect on its business, operating results, or financial condition. The Company has been named in the following proceeding: Christina Sparks, et al v. Pioneer Natural Resources, et al., Filed in the District Court, 142nd Judicial District, Midland County, Texas. On August 31, 2017, an accident occurred while a five-employee crew of Big Lake Services, LLC, a subsidiary of Nine (“Big Lake Services”), was performing workover services at an oil and gas wellsite near Midland, Texas, operated by Pioneer Natural Resources USA, Inc. (“Pioneer Natural Resources”), resulting in the death of a Big Lake Services employee, Juan De La Rosa. On December 7, 2017, a lawsuit was filed on behalf of Mr. De La Rosa’s minor children in the Midland County District Court against Pioneer Natural Resources, Big Lake Services, and Phillip Hamilton related to this accident. The petition alleges, among other things, that the defendants acted negligently, resulting in the death of Mr. De La Rosa. On March 14, 2018, a plea in intervention was filed on behalf of Mr. De La Rosa’s parents, alleging similar claims. The plaintiffs and intervenors are seeking money damages, including punitive damages. Discovery proceedings are underway in this matter, and trial is scheduled for mid-2019. The Company maintains insurance coverage against liability for, among other things, personal injury (including death), which coverage is subject to certain exclusions and deductibles. The Company tendered this matter to its insurance company for defense and indemnification of Big Lake Services and the other defendants. While the Company maintains such insurance policies with insurers in amounts and with coverage and deductibles that it, with the advice of its insurance advisors and brokers, believes are reasonable and prudent, the Company cannot ensure that this insurance will be adequate to protect it from all material expenses related to current or potential future claims for personal and property damage or that these levels of insurance will be available in the future at economical prices. Self-insurance The Company uses a combination of third-party insurance and self-insurance for health insurance clams. The self-insured liability represents an estimate of the undiscounted ultimate cost of uninsured claims incurred as of the balance sheet date. The estimate is based on an analysis of trailing months of incurred medical claims to project the amount of incurred but not reported claims liability. The estimated liability for self-insured medical claims was $1.5 million and $1.3 million at September 30, 2018 and December 31, 2017, respectively, and is included under the caption “Accrued expenses” on the Condensed Consolidated Balance Sheets. Although the Company does not expect the amounts ultimately paid to differ significantly from the estimates, the self-insurance liability could be affected if future claims experience differs significantly from historical trends and actuarial assumptions. Scorpion Contingent Liability In connection with the acquisition of Pat Greenlee Builders, LLC (“Scorpion”) in 2015, the Company recorded a liability for contingent consideration to be paid in shares of Company common stock and in cash, contingent upon quantities of Scorpion Composite Plugs TM The contingent consideration related to the Scorpion acquisition is reported at fair value, based on discounted cash flows. Significant inputs used in the fair value measurement include estimated gross margin related to forecasted sales of the plugs, term of the agreement, and a risk adjusted discount factor. The revaluation gains and losses are included in “General and administrative expenses” in the Condensed Consolidated Statements of Income and Comprehensive Income (Loss). The following is a reconciliation of the beginning and ending amounts of contingent consideration obligation (level 3) related to the Scorpion acquisition for the nine months ended September 30, 2018 and the year ended December 31, 2017: September 30, 2018 December 31, 2017 (in thousands) Balance at beginning of year $ 1,730 $ 3,187 Common stock issuance — (547 ) Payment — (1,325 ) Revaluation adjustment 1,715 415 Balance at end of the period $ 3,445 $ 1,730 Contingent liabilities related to the Scorpion acquisition include $3.4 million and $1.7 million and are reported in “Accrued expenses” in the Condensed Consolidated Balance Sheets at September 30, 2018 and December 31, 2017, respectively. The contingent liabilities related to Scorpion are expected to be paid by December 31, 2018.

Stockholders' Equity	10. Stockholders’ Equity In January 2018, the Company completed its IPO of 8,050,000 shares of common stock (including 1,050,000 shares pursuant to an over-allotment option) at a price to the public of $23.00 per share pursuant to a registration statement on Form S‑1 (File 333‑217601), as amended and declared effective by the SEC on January 18, 2018. After subtracting approximately $16.9 million of underwriting discounts, commissions, and offering expenses, the Company received net proceeds of approximately $168.3 million from its IPO.

Taxes

Income Tax Disclosure [Abstract]
Taxes	11. Taxes The Company’s effective tax rate fluctuates based on, among other factors, changes in statutory tax rates, changes in pre-tax income and nondeductible items, and changes in valuation allowances. The Company’s effective tax rate for the three and nine months ended September 30, 2018 was 7.6% and 7.1%, respectively, compared to (17.9%) and (8.5%) for the three and nine months ended September 30, 2017, respectively. The change in effective tax rate for the three and nine months ended September 30, 2018 was primarily attributable to changes in pre-tax book income and valuation allowance positions as well as tax liabilities in states where income is expected to exceed available net operating losses. The Company recognized the income tax effects of the Tax Cuts and Jobs Act (the “Tax Reform”) in its audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 in accordance with Staff Accounting Bulletin No. 118, which provides SEC staff guidance for the application of ASC Topic 740, Income Taxes, in the reporting period during which the Tax Reform was signed into law. The guidance also provides for a measurement period of up to one year from the enactment date of the Tax Reform for the Company to complete its accounting for the U.S. tax law changes. As such, the Company’s 2017 financial results reflected the provisional estimate of the income tax effects of the Tax Reform. No subsequent adjustments have been made to the amounts recorded as of December 31, 2017, which continue to represent a provisional estimate of the impact of the Tax Reform. The estimate of the impact of the Tax Reform was based on certain assumptions and the Company’s current interpretation of the Tax Reform. Any adjustments to the 2017 estimate due to additional clarification and implementation guidance will be reported as a component of income tax expense in the reporting period in which any such adjustments are identified, which will be no later than the fourth quarter of 2018.

Earnings Per Share [Abstract]
Income (Loss) Per Share	12. Income (Loss) Per Share Basic income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted income (loss) per share is based on the weighted average number of shares outstanding during each period and the assumed exercise of potentially dilutive stock options and restricted stock. Basic and diluted income (loss) per common share was computed as follows (in thousands, except share and per share amounts): 2018 2017 Three Months Ended September 30, Net Income Average Shares Outstanding Income Per Share Net Loss Average Shares Outstanding Loss Per Share Basic $ 13,658 23,971,032 $ 0.57 $ (5,052 ) 14,992,431 $ (0.34 ) Assumed exercise of stock options — 41,341 — — Unvested restricted stock — 376,922 — — Diluted $ 13,658 24,389,295 $ 0.56 $ (5,052 ) 14,992,431 $ (0.34 ) 2018 2017 Nine Months Ended September 30, Net Income Average Shares Outstanding Income Per Share Net Loss Average Shares Outstanding Loss Per Share Basic $ 24,352 23,264,014 $ 1.05 $ (37,871 ) 14,492,757 $ (2.61 ) Assumed exercise of stock options — 31,879 — — Unvested restricted stock — 308,029 — — Diluted $ 24,352 23,603,922 $ 1.03 $ (37,871 ) 14,492,757 $ (2.61 ) For the three and nine months ended September 30, 2017, the computation of diluted income (loss) per share excluded outstanding stock options and unvested restricted stock because their inclusion would be anti-dilutive given the Company was in a net loss position. The average number of securities that were excluded from diluted income (loss) per share that would potentially dilute earnings per share for the periods in which the Company experienced a net loss were as follows: 2018 2017 Three months ended September 30, — 212,181 Nine months ended September 30, — 205,324

Condensed Consolidated Financial Information	Condensed Consolidated Financial Information The accompanying Condensed Consolidated Financial Statements have not been audited by the Company’s independent registered public These Condensed Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the SEC for interim financial information. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States of America (“GAAP”) for complete financial statements. Therefore, these Condensed Consolidated Financial Statements should be read in conjunction with the Company’s audited Consolidated Financial Statements and notes thereto for the year ended December 31, 2017, which are included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 filed with the SEC. The operating results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year.
Principles of Consolidation	Principles of Consolidation The Condensed Consolidated Financial Statements include the accounts of Nine and its wholly owned subsidiaries. All inter-company accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. These estimates are based on management’s best knowledge of current events and actions that the Company may undertake in the future. Such estimates include fair value assumptions used in purchase accounting and in analyzing goodwill, other intangibles and long-lived assets for possible impairment, useful lives used in depreciation and amortization expense, stock-based compensation fair value, estimated realizable value on excess and obsolete inventories, deferred taxes and income tax contingencies, and losses on accounts receivable. It is at least reasonably possible that the estimates used will change within the next year.
