U.S. Well Services, Inc. (USWSW) operates as a subsidiary of ProFrac Holding Corp. following its acquisition in November 2022, providing high-pressure hydraulic fracturing and pressure pumping services to exploration and production companies in the upstream oil and gas industry across unconventional basins in the United States, including the Permian, Eagle Ford, Marcellus, Utica, and Bakken formations; core offerings encompass electric-powered fracturing fleets under the Clean Fleet brand, conventional diesel fleets, well completion and stimulation solutions, well intervention services such as plug and abandonment and workover operations, and advanced technologies for emissions reduction, noise mitigation, and operational efficiency using natural gas-powered electric systems with over 110 patents. Founded in 2012 and headquartered in Houston, Texas, the company maintains district operations in key regions such as West Virginia, Ohio, Pennsylvania, and Texas, targeting major shale plays with a focus on high-performance fleets capable of demanding pressure and flow rates. The 2022 acquisition by ProFrac Holding Corp. integrated USWS's electric frac technology into a larger platform, expanding the combined entity's fleet to 44 active units including 12 electric fleets, yielding annual cost synergies of approximately $35 million, eliminating prior license fees, and positioning it as the largest provider of electric fracturing services while accelerating ESG initiatives through reduced emissions and fuel costs.
