This article provides an overview of basin modeling results in the northwestern part of Tomsk region. In the research basin subsidence and thermal history reconstruction were investigated. Irregular distribution of heat flow in this area can be explained by rifting processes and influence of the massive granitoid intrusion. Many years of work allowed TomskNIPIneft to create a geochemical knowledge base of source rocks and types of oil in Western Siberia. As a result, it was possible to use generalized kinetic model for further investigation of the region. Vitrinite reflectance of coal and geochemical parameters of Bazhenov organic matter (4/1 MDBT и Тmax) were used for paleotemperature calibration. This analysis gave us a possibility to predict time and volumes of Bazhenov hydrocarbon generation and to allocate two generation sources of a different nature. In the research migration and accumulation modeling parameters were described. Based on the modeling results it was concluded that overpressure and automated hydraulic fracturing trigger primary migration. Two different methods of secondary migration calculation were compared. Despite some limitations, the results have shown a good match between modeled and real data (this is illustrated by accumulation map). Consequently, general plan of basin modeling of the West Siberian region was established, including stages and goals of oncoming project. According to the plan, this research is the result of the first (regional) stage of the basin modeling project. The results can be used separately as a tool for managing geological exploration, as well as a general information source for detailed modeling at the local scale.
