CNX Resources Corp, formerly Consol Energy is a legacy coal producer transitioning to a natural gas exploration and production firm. The company produces natural gas across a wide swath of Appalachia, although growth is focused exclusively in the Marcellus and Utica shales. In 2015, Consol produced roughly 900 million cubic feet of natural gas per day. Coal production after recent asset sales is expected to be approximately 30 million tons per year.
