​Lithological, geochemical and geophysical parameters of the Bazhenov Formation were analyzed in the poorly studied region in the south of the South-Nadimskaya megamonoclise on the Povhovskaya area. The bottom-to-top sequence of the Bazhenov Formation in this region is composed of 4 patterns: siliceous mudrocks - kerogenous siliceous mudrocks - clayey-siliceous mudrocks carbonate-siliceous mudrocks with carbonate lenses. These lithotypes differ by TOC values. GIS data of the studied section were comparing with the core. According to the cross-plot modeling (GIS-GIS ratios) 4 types of rocks were distinguished, that are characterized by their own area of parameters distribution. No differences were revealed in the lithotypes by biomarker parameters. According to geochemical parameters organic matter is related to the II type of kerogenous, that is aquagenous, and correspond to the main oil formation stage. In general Bazhenov Formation rocks characterized by low porosity (0,32-2,32 %)
