    The Bazhenov formation is a source of unconventional hydrocarbons and a complex object of study. Oil accumulations in the Bazhenov formation are not controlled by the structural factor. In this article, based on the results of basin modeling, the priority geological and geochemical parameters that affect the distribution of unconventional hydrocarbon accumulations in the sediments of the Bazhenov formation are identified. The article describes the initial geological, lithological, petrophysical, geochemical and thermal parameters necessary for the analysis of the hydrocarbon system of the Bazhenov formation. The paper presents the results of calculating a 2D model of a regional sublatitudinal profile of the West Siberian basin. The calibration of geological and thermal models based on the data on reservoir temperatures and pressures, as well as on the vitrinite reflectance (Ro) and Tmax pyrolysis is illustrated. The analysis of the sensitivity of the model to changes in the kinetic spectrum of kerogen destruction of the Bazhenov formation has been carried out. Criteria for localization of the most promising areas of the Bazhenov shale formation are proposed. On the basis of the work done, it was shown that the basin modeling tool in combination with the results of geological and geochemical studies allows us to distinguish promising areas within bituminous formations. The key parameters are maturity of organic matter, the amount of generation and adsorption of hydrocarbons, as well as overpressure zones.
