Summary:
Bazhenov formation is the most famous shale formation of Russia, which is an unconventional hydrocarbon resource. It has a complicated structure and unique diversity in the entire West-Siberian basin. The main aim of this study is to identify patterns of distribution of the Bazhenov formation, characterize changes in its properties, the completeness of its geological section, as well as structural zoning within the territory where the islands existed at the time of the beginning of the accumulation of Bazhenov formation. 3D seismic survey was interpreted and structural maps were made, areas of Bazhenov formation and older deposits low thickness and were identified, and the dislocation of granite basement massifs was mapped and Bazhenov formation geological section was classified by investigation of core and log data.
