Characterization of the Organic Matter in the Bazhenov Formation Deposits From Northern and Central Parts of Western Siberia

The object of the study is the organic matter from the Bazhenov Formation. Rock-Eval pyrolysis, GC×GC-MS analysis of core extracts, IRMS of gases and kerogen in the Bazhenov Formation shale rocks were performed to characterize the organic matter from Northern and Central parts of Western Siberia. The studies revealed that variations in quality of the BF organic matter in central and peripheral regions are related to differences in both the thermal maturity and sedimentation conditions. More oxidative burial environment in South-Eastern and Northern regions resulted in lower generation potential of the Bazhenov Formation deposits when compared to in Central parts of Western Siberia.
