Abstract
Summary In this study, we consider maturity trends for Tmax and other parameters measured by Rock-Eval pyrolysis for one of the largest organic-rich oil shale formations - the Bazhenov Formation, Western Siberia, Russia. The natural maturity trends reflecting generation, migration, and accumulation of hydrocarbons were compared with artificial maturation experimental data. The experiments showed similar maturity trends for samples with different TOC content, which allowed us to consider the Bazhenov Formation as an entire petroleum system with the common source of organic matter and common maturity trends. Described maturity trends and obtained correlations between maturation and pyrolysis parameters could be used for advanced maturity evaluation for the Bazhenov formation. The suggested approach could also be useful in geochemical studies of other source rock formations.
