The late Devonian (Frasnian, Fammenian) and basal Mississippian (Tournasian) in age Woodford Shale was studied in Murray, Carter, and Pontotoc Counties, Oklahoma. The purpose of this study was to determine if a relationship exists between outcrop lithofacies and gamma-ray response and if ultimately this relationship can be extended into the subsurface. Over 500 gamma-ray readings were collected from five studied outcrops to complete this work. Thin-section analysis, total organic carbon, x-ray diffraction and vitrinite reflectance data were also integrated in this study.Boone Pickens School of Geolog
