The core counties appear to be Panola, Harrison and Shelby. The productive interval of the shale is greater than 10,000 feet below the land surface. There has been some confusion in whether the formation is the Haynesville Shale and/or the Bossier Shale because of different geological naming conventions in Texas and Louisiana. It is generally recognized that the shale interval in East Texas is Lower Bossier that correlates with the Haynesville of Louisiana. The Upper Bossier Formation is distinguished from the Lower Bossier Formation by its location, to the southwest, and the fact that it is more sand-rich. Most operators have designated the field for wells drilled in the Bossier Shale Formation in Shelby, Panola and Harrison counties as the Carthage, North (Bossier Shale). However, as the area is devel
