Commitments and Contingencies Disclosure [Abstract]  
          We entered into certain commitments for fixed assets, consumables and services incidental to the ordinary conduct of our business, generally for quantities required for our operations and at competitive market prices. These commitments are designed to assure sources of supply and are not expected to be in excess of normal requirements. As of December 31, 2021, there were no outstanding contractual commitments. At December 31, 2021, the total remaining commitments and other obligations for all of our short-term lease and lodging arrangements was $3.7 million.
          The Company enters into purchase agreements with its sand suppliers (the "Sand Suppliers") to secure supply of sand as part of its normal course of business. The agreements with the Sand Suppliers require that the Company purchase a minimum volume of sand, based primarily on a certain percentage of our sand requirements from our customers or in certain situations based on predetermined fixed minimum volumes, otherwise certain penalties (shortfall fees) may be charged. The shortfall fee represents liquidated damages and is either a fixed percentage of the purchase price for the minimum volumes or a fixed price per ton of unpurchased volumes. Our agreements with Sand Suppliers expire at different times prior to December 31, 2025. During the years ended December 31, 2021, 2020 and 2019, no shortfall fee was recorded. However, one of our Sand Suppliers has filed a suit against us that includes claims related to alleged shortfall fees. The suit is in the early stages, and we are contesting the claims. While we cannot reasonably estimate the outcome of the matter at this time, in the opinion of management, the ultimate disposition of the action will not have a materially adverse effect on the Company.
          One of the Sand Suppliers ("SandCo") we entered into an agreement to purchase sand ("Texas Sand") has an indirect relationship with a former executive officer of the Company, because beginning in 2018, the Texas Sand was sourced from a mine located on land owned by an entity in which the former executive officer of the Company has a 44% noncontrolling equity interest. The total sand purchased from SandCo during the three months ended March 31, 2020 (the period the former executive was associated with the Company) was approximately $5.3 million.
          As of December 31, 2021 and 2020, the Company had issued letters of credit of $3.7 million and $3.7 million, respectively, under the ABL Credit Facility in connection with the Company's casualty insurance policy.
Contingent Liabilities
Legal Matters
          In September 2019, a complaint, captioned Richard Logan, Individually and On Behalf of All Others Similarly Situated, Plaintiff, v. ProPetro Holding Corp., et al., (the "Logan Lawsuit"), was filed against the Company and certain of its then current and former officers and directors in the U.S. District Court for the Western District of Texas.
          In July 2020, the Logan Lawsuit Lead Plaintiffs Nykredit Portefølje Administration A/S, Oklahoma Firefighters Pension and Retirement System, Oklahoma Law Enforcement Retirement System, Oklahoma Police Pension and Retirement System, and Oklahoma City Employee Retirement System, and additional named plaintiff Police and Fire Retirement System of the City of Detroit, individually and on behalf of a putative class of shareholders who purchased the Company’s common stock between March 17, 2017 and March 13, 2020, filed a
third amended class action complaint in the U.S. District Court for the Western District of Texas, alleging violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule l0b-5 promulgated thereunder, and Sections 11 and 15 of the Securities Act of 1933, as amended, based on allegedly inaccurate or misleading statements, or omissions of material facts, about the Company’s business, operations and prospects against the Company, and certain of its current and former officers and directors. On September 13, 2021, the Court partially granted and partially denied motions to dismiss filed by the Company and the individual defendants. Discovery is still ongoing.
           In May 2020, the U.S. District Court for the Western District of Texas consolidated two shareholder derivative lawsuits previously filed against the Company and certain of its current and former officers and directors into a single lawsuit captioned In re ProPetro Holding Corp. Derivative Litigation (the “Shareholder Derivative Lawsuit”). In August 2020, the plaintiffs in the Shareholder Derivative Lawsuit filed a consolidated complaint alleging (i) breaches of fiduciary duties, (ii) unjust enrichment and (iii) contribution. The plaintiffs did not quantify any alleged damages in its complaint but, in addition to attorneys’ fees and costs, they seek various forms of relief, including (i) damages sustained by the Company as a result of the alleged misconduct, (ii) punitive damages and (iii) equitable relief in the form of improvements to the Company’s governance and controls. On September 15, 2021, the Court granted the Company's motion to dismiss the complaint in its entirety, without prejudice.
           On November 19, 2021, the Company received a demand letter from a law firm representing one of the purported shareholders of the Company that previously filed the dismissed Shareholder Derivative Lawsuit. The demand letter alleged facts and claims substantially similar to the Shareholder Derivative Lawsuit. The Board of Directors has constituted a committee to evaluate the demand letter and recommend a course of action to the Board of Directors, and the committee has retained counsel to assist with its review. The committee’s review is ongoing.
           In October 2019, the Company received a letter from the SEC indicating that the SEC had opened an investigation into the Company, which followed the SEC’s issuance of a formal order of investigation, and requesting that the Company provide certain information and documents, including documents related to the Company's expanded audit committee review and related events. In November 2021, the Company entered a settlement with the SEC resolving the investigation. The Company was not required to pay any monetary penalty and has no ongoing undertakings in connection with the settlement.
          We are presently unable to predict the duration, scope or result of the Logan Lawsuit, or any other related lawsuit or investigation. As of December 31, 2021, no provision was made by the Company in connection with this pending lawsuit as the final outcome cannot be reasonably estimated.
Environmental and Equipment Insurance
          The Company is subject to various federal, state and local environmental laws and regulations that establish standards and requirements for protection of the environment. The Company cannot predict the future impact of such standards and requirements, which are subject to change and can have retroactive effectiveness. The Company continues to monitor the status of these laws and regulations. Currently, the Company has not been fined, cited or notified of any environmental violations that would have a material adverse effect upon its financial position, liquidity or capital resources. However, management does recognize that by the very nature of the Company's business, material costs could be incurred in the near term to maintain compliance. The amount of such future expenditures is not determinable due to several factors, including the unknown magnitude of possible regulation or liabilities, the unknown timing and extent of the corrective actions which may be required, the determination of the Company's liability in proportion to other responsible parties and the extent to which such expenditures are recoverable from insurance or indemnification.
Effective November 2021 and in connection with our equipment insurance program renewal, the Company will self-insure up to $10 million per occurrence for certain losses arising from or attributable to fire and/or explosion at the wellsites.
Regulatory Audits
          In 2020, the Texas Comptroller of Public Accounts (the “Comptroller”) commenced a routine audit of the Company's motor vehicle and other related fuel taxes for the periods of July 2015 through December 2020. As of December 31, 2021, the audit is still ongoing and the final outcome cannot be reasonably estimated.
          In January 2022, we entered into a settlement agreement with the Comptroller for a $10.7 million tax refund, net of consulting fees, in connection with certain limited sales and use tax for the audit period July 1, 2015 through December 31, 2018. The net refund will be recorded in our first quarter of 2022, the period the refund is expected to be received by the Company. During the year December 31, 2021, the net refund received by the Company from the sales and excise and use tax audit was approximately $2.1 million, which was recorded as part of other income in the statement of operations
