There were identified three big petroleum systems in the Mesozoic of Northern West - Siberian and in western part of the Yenisei-Khatanga sedimentary basins - Jurassic, Upper Jurassic - Aptian, and Aptian-Albian- Senomanian. The Bazhenov Formation appears to be main oil source in the basin, and its age analogs, the Malyshev and the Sukhodunka Formations in the basin’s northeast. Enriched in non-marine organic matter sediments from Lower-Middle Jurassic and Aptian-Albian- Senomanian prove the main gas generating formations. In the deepest parts of the basin most buried in the deep gas-generating zone is the Bazhenov Fm.

Most essential characteristic of northern areas of West Siberian and western part of the Yenisei-Khatanga basins is the significant role played by terrigenous material in organic matter, which greatly influenced both oils composition, and oil and gas resources to reserves ratio.

Organic matter of major oil and gas generating formations was given a detailed characterization. Described are the relations “oil source-rock - oils”.
