Summary:

The intercratonic West Siberian sedimentary basin is the most prolific oil- and gas-producing area in Russia, which contains 14 supergiant fields. The Bazhenov prolific source-rocks as classical petroleum system were described by series of electronic maps and basin modeling. The Petroleum generative depressions and mature area of the Volgian source, some vertical migration pathway, the timing of oil expulsion rocks were determined. The Bazhenov shales contain very rich type I and II kerogen. Organic carbon content and residual petroleum potential of the Bazhenov Formation are extremely high in the Middle Ob River area, decrease in the Southern and Northern parts, and the lowest in the marginal zones of the basin.
