Antero Resources Corporation

An independent oil and natural gas producer that drills for natural gas, natural gas liquids, and oil in the Marcellus and Utica shale formations of the Appalachian Basin, with headquarters in Denver. Founded in 2002 by Paul M. Rady and Glen C. Warren Jr., the company grew in the Barnett Shale before selling those assets and concentrating entirely on Appalachia. Its name echoes Mount Antero, a Colorado peak honoring Chief Antero of the Ute people.
