In the east part of the West Siberian sedimentary basin the Bazhenov Formation has the Tarkosale, Vakh, and Nyurolka types of section. We have studied the lithology and geophysical characteristics of its rocks and the geochemistry of its organic matter and described the obtained characteristics of the sections. The greatest attention is paid to the geochemistry of organic matter. The results of the investigation indicate that the aquatic organic matter of the studied section types of the Bazhenov Formation was concluded to differ in content and composition of bitumoids primarily due its different maturity degree. The electrical resistivity and gamma activity of the studied section changes with proportion ratio of clay and carbonate components in the composition of their rocks. That can be preliminary explained by the position of the sections relative to the paleodepth and regional provenance.
