Devon Energy Corp/de
An American independent energy company that explores for and produces oil, natural gas, and natural gas liquids from shale basins across the United States, including the Delaware, Eagle Ford, and Anadarko regions. Founded in 1971 in Oklahoma City by accountant John Nichols and his lawyer son Larry, it grew from a small family business into one of the country's largest independent producers. Its 2002 purchase of Mitchell Energy helped spark the modern shale boom.
