FORECAST OF PETROLEUM BEARING OF THE PRE-JURASSIC SECTION BELONGING TO BAKCHAR DEPRESSION USING THE GEOTHERMAL ENERGY DATA (TOMSK REGION)

Based on paleotemperature modeling carried out for the Lower Jurassic Togur Formation and determining of the relative density of its generation potential, a zoning of the studied area was realised. The area was ranked according to the level of prospects for further research to search for petroleum accumulations of pre-Jurassic section in the southern part of the Tomsk Region within the Bakchar mesodepression and adjacent structures. The ranking took into account the reservoirs quality for different petrotypes of the pre-Jurassic basement rocks as well as the density of tectonic faults in the described areas.
