Oil & Gas Suppliers & Vendors: US Directory
A maintained index of U.S. oil and gas companies, organized by metro, basin, and industry segment. Choose a region to see the operators, oilfield-services firms, midstream companies, and equipment makers that work there.
How this directory is organized
The U.S. oil and gas industry is regional. Operators, drillers, and service companies cluster by basin and by the metros that host their headquarters and engineering talent. To find the companies that matter, you start with a place.
Each regional directory below lists companies by what they do (operators, oilfield services, midstream, drilling, equipment, and more) and, where relevant, by basin. The directories are maintained and dated, not scraped once and abandoned.
One segment taxonomy, six regions
Every regional directory tags companies against the same 14 industry segments — operators, oilfield services, midstream, equipment, and more. Not every segment shows up in every region; which ones do is itself a signal of how that market is built.
