EGSP Tennessee No. 3 well is located in the Grainger County Industrial Park in Grainger County, Tennessee, at lat. 30?18?55?N, long. 53?24?33?W. This particular site was selected for the purpose of gathering geological information on the Chattanooga Shale and testing an exploration rationale for exploitation of the potential gas contained within the formation matrix and its fracture system. The proposed exploration rationale was based on the Chattanooga Shale being truncated by the Saltville Thrust fault, a structural setting which provides a geologically desirable site. This is due to the expected high frequency of naturally occurring, thrust-induced fractures ; such a high fracture density is an essential requirement for developing productive Devonian shale wells. Another geologic factor which supports the selection of this site is that approximately 180 ft of organic shale were encountered in the EGSP Tennessee No. 7 and EGSP Tennessee No. 8 test wells located a few miles away. Both of these wells exhibited high radioactivity in the Cleveland, Lower Huron, and Rhinestreet members of the Chattanooga Shale Formation.
