pdf Formation history of anticlinal trap structures and oil and gas potential of sedimentary megacomplexes of Western Siberia
In the West Siberian petroleum province, the main hydrocarbon reserves and resources are concentrated in Jurassic-Cretaceous strata of the sedimentary cover, localized in sandstones reservoirs and controlled by anticline structures. Furthermore, productive stages vary significantly and become younger from south to north. Research conducted at the IPGG SB RAS has shown that the significant differences in the petroleum potential of sedimentary strata in various regions of Western Siberia are largely related to the formation characteristics and modern structure of anticline structures–traps for hydrocarbon accumulations. The petroleum potential of sedimentary megasystemes, and individual reservoirs in various parts of the West Siberian Basin is related to their geological structure, the position in the section and the depth of source rocks, disjunctive tectonics, and other factors. At the same time, given that the overwhelming majority of oil and gas fields in the West Siberian petroleum province are confined to anticlinal structures, and the levels of oil and gas-bearing capacity are directly related to their expression in the relief of various stratigraphic levels, this factor is one of the most important.

Keywords: Jurassic–Cretaceous strata of the sedimentary cover, anticlinal structure, oil and gas potential of sedimentary megasystemes, West Siberian petroleum province.

pdf Model of geological structure and prospects of petroleum bearing North Kara sedimentary basin
Based on a comprehensive interpretation of seismic survey analyses and geological data on the islands and continental margin of Siberia, a model of the geological structure of the North Kara sedimentary basin is considered, and its seismostratigraphic and structural-tectonic characteristics are given. It is concluded that for most of the basin the sedimentary cover is composed of Paleozoic strata from the Cambrian to the Permian inclusive, the thickness of which in depression zones reaches 13-14 km. The thickness of Mesozoic cover in most of the basin does not exceed 1 km; in the north-west, where the North Kara basin borders the Barents Sea, the thickness of Mesozoic sedimentary rocks increases to 5-6 km, and here Paleozoic, Triassic, Jurassic and Cretaceous seismogeological intricate structures are distinguished in the sedimentary cover.
In terms of oil and gas, the North Kara sedimentary basin is identified as part of the promising petroleum province of the same name, which has high potential from seismostratigraphic and structural-tectonic points of view. In the structural plans of various stratigraphic levels, large depressions and uplifts are developed, which can be associated with zones of oil and gas formation and accumulation; in various sedimentary structures from the Cambrian to the Jurassic inclusive, anticlinal and complex traps are identified - petroleum promising objects.

Keywords: sedimentary cover, Paleozoic, Mesozoic, seismic stratigraphy, seismic geological structure, structural and tectonic characteristics, petroleum province, petroleum promising object, North Kara sedimentary basin.
