Alginite-Rich Layers in the Bazhenov Deposits of Western Siberia

In this study, we identified the luminescent layers containing a significant amount of alginite in Upper Jurassic–Lower Cretaceous Bazhenov Formation named “the alginite-rich layers”. Lithological and geochemical methods were used to determine distinctive features these evaluate their impact on total petroleum generation potential Formation. We have shown that composition differs significantly from organic-rich siliceous rocks. Rock-Eval pyrolysis, bulk kinetics thermal decomposition, elemental analysis, pyrolysis products indicate type I kerogen be predominant component organic matter (OM). Isotope carbon, nitrogen, sulfur was provide insights into origin formation pathways. The proved good regional stratigraphic markers due widespread distribution over central part Western Siberia. They can also applied for maturity evaluation deposits immature middle oil window, since luminescence changes color intensity during maturation.
