About This Report

Patterson-UTI is a Houston, Texas-based oilfield services company that primarily owns and operates one of the largest fleets of land-based drilling rigs in the United States and a large fleet of pressure pumping equipment. We also have a number of “lighter-asset” businesses with a heavy technology focus and a smaller footprint. These include our Superior QC business, which provides software and services used to improve the accuracy of directional and horizontal wellbores, wellbore quality, and on-bottom ROP (rate of penetration), and our Current Power business, which provides in-house electrical engineering, control system automation and installation services to the energy and marine industries.

We had approximately 6,000 full-time employees as of December 2022.
