Hydrogeological model of the West Siberian megabasin is based on the fluid-geodynamic concept of underground water reservoirs. The concept was presented at the XXVII Session of the International Geological Congress (Moscow, 1984). Allocated three separate hydro pools—Cenozoic, Mesozoic, and Paleozoic. The entire section is divided into seven hydrogeological systems: Oligocene-Quaternary, Turonian-Paleogene, Aptian-Albian-Cenomanian, Neocomian, Upper Jurassic, mid- lower Jurassic, and Triassic-Paleozoic. Due to the accumulated data the Paleozoic-Triassic hydrogeological complex is divided into two independent—Triassic (7) and Paleozoic (8).
To date, based on the deep and ultra-deep bores, 2D and 3D-Geophysical Research set litho-facies composition and reservoir properties of the rocks at great depths, projected oil and gas siliciclastic and igneous rocks of the pre-Jurassic basement of the West Siberian Plain. In various areas established Triassic intrusions in the rift zones and the overlying sedimentary-volcanic rock complexes. In the context of the Paleozoic clastic stand—carbonate strata of the Permian, Carboniferous, and Devonian. Viewing inversion model of ion-salt composition and decrease water salinity with depth. Inversion and micro component composition of the water indicate the shear main zone of oil accumulation in the north megabasin to depths of 5-7 km, in the Triassic and Paleozoic complexes. Thus, as previously performed by V.M. Matusevich hydrogeological parameters regional forecast oil and gas, is confirmed.
