The Tennessee Division of Geology under contract to the Morgantown Energy Technology Center of the U.S. Department of Energy has drilled eight NX core holes in eastern Tennessee. The coring program, under the supervision of R. C. Milici, was designed to retrieve continuous core sections for a detailed characterization study of the Chattanooga Shale. The Geophysical wire-line logging for the NX drill holes was performed by the U.S. Geological Survey.
