The Chattanooga Shale is an Upper Devonian shale formation that runs through Tennessee, Alabama and Kentucky. It runs concurrently and is located below the Floyd Shale, which is an Upper Mississippian Shale formation.
The Chattanooga Shale is not a major focus of the oil and gas industry since other shale plays are more attractive and delineated at this time. Companies that are currently developing its acreage include Geomet (GMET) and CNX Gas (CXG).
