FrontiersTesting Utility of Organogeochemical

It is generally accepted that in mature shales, biomarkers and pyrolysis proxies are not very helpful in understanding the source/type of organic matter (OM), paleo-redox conditions during deposition, and thermal maturity. This study was to test the efficacy of these proxies in mature Marcellus Shale (VRo > 1). Samples were collected from oil-prone (WV-7) and gas-prone (WV-6) wells in Wetzel
