Abstract

Stratigraphic studies of the Devonian and Mississippian Ohio, Sunbury, New Albany, and Chattanooga Shales (consisting primarily of black, organic-rich shale) in the eastern portions of Ohio, Kentucky and Tennessee indicate that radioactive units evident on subsurface gamma-ray logs from oil and gas wells penetrating these formations can be distinguished in outcrops and in cores by using a scintillometer. Except for thin green-shale beds distributed throughout the black shale, exposures of the Ohio, New Albany, and Chattanooga Shales are lithologically homogeneous. Use of this technique has shown, however, that these black-shale formations contain seven major radioactive units, which can now be correlated with named surface and subsurface units.
