Geochemistry of Mississippian and Devonian oil shales of northeastern Kentucky
Detailed chemical analysis were conducted on 10 cores drilled in Lewis and Fleming Counties of Kentucky in an oil-shale resource assessment funded by the US Department of Energy. The stratigraphic units studied include the Sunbury shale and the Ohio shale, which is divided (from top to bottom) into the Cleveland member, the Three Lick bed, and the Huron member. The chemical analysis include C, H, N, S, major element oxide, and trace-element determinations from 760 samples. Carbon concentration was found to increase from top to bottom in the Sunbury shale and Huron member, and decrease in the Cleveland member of the Ohio shale. Average carbon concentrations were 11%, 6%, and 9% by wt in these intervals, respectively. Oil yield was determined by Fischer-assay and a good correlation with carbon was found. The Cleveland produced approximately 10% more oil per unit of carbon than the Sunbury. The Sunbury shale was the least siliceous of the stratigraphic intervals and had the highest concentration of trace elements.
