Conocophillips
One of the world's largest independent oil and gas producers, ConocoPhillips focuses on finding and extracting crude oil, natural gas, natural gas liquids, and liquefied natural gas rather than running refineries or gas stations. The company was born in 2002 from a merger of Conoco Inc. and Phillips Petroleum Company, the latter founded in 1917 by brothers Frank and L.E. Phillips. Its Conoco name traces to the Continental Oil and Transportation Company, founded in 1875, which distributed kerosene to pioneers in the American West.
