Deep resistivity “turnover” effect at oil generation “peak” in the Woodford Shale, Anadarko Basin, USA

Abstract The Devonian Woodford Shale in the Anadarko Basin is a highly organic, hydrocarbon source rock. Accurate values of vitrinite reflectance (R o) present in the Woodford Shale penetrated by 52 control wells were measured directly. These vitrinite reflectance values, when plotted against boreho...
