vitrinite reflectance of woodford shale oklahoma

Events - Oklahoma City Geological Society

Sampled Woodford organic-rich shales contain very little vitrinite; however they contain abundant solid bitumen. Thermal maturity data from solid bitumen were converted to a vitrinite reflectance equivalent Jacob 1989 and compared with pyrolysis data e.g. Tmax and Hydrogen Index . Both methods were found to be in excellent agreement.【Get Price】
