Chesapeake Energy Corporation

A major American energy company that explores for and produces natural gas and oil, pulling fuel from shale rock beneath the Appalachian Basin and Louisiana. Founded in 1989 in Oklahoma City by Aubrey McClendon, it helped pioneer the drilling-and-fracking techniques that unlocked shale gas. The founder named it Chesapeake as a tribute to his love of the Chesapeake Bay, and the company later merged with Southwestern Energy to become Expand Energy, one of the nation's largest natural gas producers.
