The article presents the results of integrated geophysical studies conducted in an area encompassing the Russko-Chaselsky Ridge (Western Siberia). The work is aimed at investigating the tectonic structure of the area, with a focus on the characterization of rift-related formations and manifestations of strike-slip dislocations. The authors carried out a comprehensive analysis of 2D and 3D seismic survey data, as well as gravity and magnetic field data. The study includes fault mapping and the correlation of geological structures with diverse geophysical data through modeling. The tectonic structures of the Koltogory-Urengoy and Khudosey graben-rifts, as well as the Russko-Chaselsky Ridge, were examined. Based on the correlation of positive gravity and magnetic field anomalies with the localization of Triassic-age graben-rifts, an additional segmented branch within the rift system was identified. An analysis of local anomalies in potential fields suggests the presence of strike-slip deformations, which may be valuable for preliminary studies in areas with sparse seismic survey networks and for planning exploration activities, including seismic surveys. The results contribute to refining the tectonic model of the region. The authors emphasize the need for further application of integrated geophysical methods to achieve detailed mapping of the tectonic structures in the West Siberian Basin, assess the role of fault dislocations in forming oil and gas traps, and understand their control over hydrocarbon migration.
