National Fuel Gas Co
An integrated natural gas company that pumps gas in the Appalachian Basin through its production arm Seneca Resources, moves it along interstate pipelines, and delivers it to homes across western New York and northwestern Pennsylvania. Incorporated in 1902, it grew from natural gas interests once part of John D. Rockefeller's Standard Oil trust. Its region birthed the industry: a Fredonia, New York gunsmith named William Hart drilled America's first natural gas well.
