Accounting Policies [Abstract]
Organization and Basis of Presentation	1. Organization and Basis of Presentation We are an energy infrastructure company with a pure-play focus on midstream natural gas compression. We believe we are the leading provider of natural gas compression services to customers in the oil and natural gas industry throughout the U.S. and a leading supplier of aftermarket services to customers that own compression equipment in the U.S. We operate in two business segments: contract operations and aftermarket services. Our predominant segment, contract operations, primarily includes designing, sourcing, owning, installing, operating, servicing, repairing and maintaining our owned fleet of natural gas compression equipment to provide natural gas compression services to our customers. In our aftermarket services business, we sell parts and components and provide operations, maintenance, overhaul and reconfiguration services to customers who own compression equipment. The accompanying unaudited condensed consolidated financial statements included herein have been prepared in accordance with GAAP and the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP are not required in these interim financial statements and have been condensed or omitted. Management believes that the information furnished includes all adjustments, consisting only of normal recurring adjustments, which are necessary to present fairly our consolidated financial position, results of operations and cash flows for the periods indicated. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements presented in our 2018 Form 10-K, which contains a more comprehensive summary of our accounting policies. The interim results reported herein are not necessarily indicative of results for a full year. Certain prior year amounts have been reclassified to conform to the current year presentation. Recent Business Developments Elite Acquisition On June 23, 2019, we entered into an asset purchase agreement with Elite Compression pursuant to which we will acquire from Elite Compression substantially all of its assets, including a fleet of predominantly-large compressor units comprising approximately 430,000 horsepower, a fleet of vehicles, real personal property and parts inventory, and certain liabilities for aggregate consideration of $205.0 million cash and 21,656,683 newly-issued shares of Archrock common stock. We intend to fund the cash portion of the purchase price with borrowings on the Credit Facility. The Elite Acquisition is expected to close in the third quarter of 2019 subject to certain closing conditions and the consummation of the Harvest Sale (see below). Harvest Sale On June 23, 2019, we entered into an asset purchase agreement with Harvest pursuant to which Harvest will acquire from us approximately 80,000 active and idle compression horsepower, vehicles and parts inventory for consideration of $30 million to be paid in cash. The Harvest Sale is expected to close in the third quarter of 2019, subject to customary closing conditions. During the three and six months ended June 30, 2019, we incurred transaction costs of $2.5 million related to the Elite Acquisition and Harvest Sale, which is reflected in transaction-related costs in our condensed consolidated statements of operations.
