Battelle-Columbus Laboratories continues to submit Individual Well Reports on the Eastern Gas Shales Project. Results and their analyses on all six tasks are reported on the C-338 Well (Wise County, Virginia). Samples from the C-338 well were cored between depths of 4870 and 5475 feet. A total of 81 samples were obtained. Considerably high hydrocarbon gas contents are observed (average hydrocarbon gas content in the canisters was 63.1%). Higher chain hydrocarbon gases are also present in significant quantities. Average hydrocarbon gas volume per unit volume of shale is 1.2. Gas release kinetics studies on C-338 shales reveal diffusion coefficients in the order of 10/sup -7/ cm/sup 2//s, which agree well with values of other shales. Excellent one-to-one correlations exist between the chemical characteristics (carbon, hydrogen contents) and hydrocarbon gas contents. Increasing carbon and hydrogen values are associated with higher hydrocarbon gas contents. Among the physical characterization data, densities are inversely related to organics contents, increasing the hydrocarbon gas contents.
