Midstream
Williams is one of North America’s largest natural gas gatherers and processors, dedicated to becoming the most reliable midstream service provider in the industry. We’re focused on running large-scale assets and running them well.
Our large-scale midstream operations in the United States (held through our significant investment in Williams Partners L.P.) include natural gas gathering, processing and storage; natural gas liquid (NGL) production and transportation; and oil transportation. Areas of operation in the United States include the West, onshore and offshore Gulf of Mexico and the Marcellus Shale.
Williams also has a growing midstream business in Canada focused on processing oil sands off-gas into NGLs and olefins. We’re the only company in the world that’s doing this. We also have a domestic olefins business that provides customers in the petrochemical industry with a full suite of products and services.
