An assessment of the geotemperature conditions of Bazhenov oil generation (Koltogor mezodepression and its framing structures)

The thermal history of oil source rocks of Bazhenov deposits was reconstructed in 8 cross-sections of representative wells of Koltogor mezodepression and the structures framing it. The tectonic history and geotemperature were reconstructed for well profiles, some located in the depression zone and others in the positive structures. A comparative analysis of the geotemperature conditions accompanying the generation of Bazhenov oils was performed
