Zoning of oil-gas potential of pre-jurassic reservoirs in Nyurol'ka megadepression (using paleotemperature modeling and drilling)
The relevance of the research consists in the necessity of assessing a search strategy (search criteria, conceptual technological scheme) of bodies in the pre-Jurassic petroleum play of Western Siberia (hard to recover reserves). The aim of the study is to identify the primary research areas of hydr...

The relevance of the research consists in the necessity of assessing a search strategy (search criteria, conceptual technological scheme) of bodies in the pre-Jurassic petroleum play of Western Siberia (hard to recover reserves). The aim of the study is to identify the primary research areas of hydrocarbon reservoirs in pre-Jurassic basement by the example of the Nurol'ka megadepression and its framing structures which are located on the main oil-field regions of Tomsk, on the left bank of the Ob River. Object of research is the drilled reservoirs of weathering crust and Paleozoic basement. The weathering crust reservoirs are formed on clay and siliceous, carbonate and acid volcanic rocks, for which the Lower-Jurassic clay is fluid seal. The reservoirs of bedrock are associated with secondary reservoirs formed by limestones, granites, rhyolites and ultrabasites under certain conditions. Fluid seals in this reservoir are clay formations of weathering crust or impermeable rocks within the basement. The main oil source formation is the Lower Jurassic Togur formation. The research is carried out based on the concept of vertical migration. The research area is located in boundaries of the oil source formation.
