- Аннотация: Comprehensive lithological and geochemical studies were conducted on core samplesfrom three wells located in the southern periphery of the West Siberian Petroleum Basin (northernpart of the Omsk region). These studies enabled the identification and detailed characterization ofthe main source rocks in the area, as well as the assessment of potential hydrocarbon generationvolumes. The organic-rich siliceous mudstones of the Bazhenov Formation, along with coals andcarbonaceous shales of the Vasyugan and Tyumen Formations, were identified as the main sourcerocks. A detailed analysis of the well sections revealed that the generation potential of the BazhenovFormation is associated with the Type II/IIS kerogen, which is characterized by early generation anda higher initial hydrogen index. The coals and carbonaceous shales of the Vasyugan and TyumenFormations were determined to possess oil-generating potential due to the anomalously high contentof liptinite macerals in the organic matter (OM) composition. Studies of the molecular and isotopiccompositions of rock extracts from both source rock and reservoir rock intervals, as well as thegas sample from the field, confirm that the fluids across the area are derived from marine OM ofthe Bazhenov Formation and the carbonaceous matter of the Vasyugan and Tyumen Formations,as well as their mixtures. The obtained results demonstrate the presence of an early-generationpetroleum kitchen in the studied area. These findings contribute to a new understanding of thehydrocarbon prospectivity of the region. The study also highlights the necessity for 3D basinmodeling to reassess the hydrocarbon resources and their localization within the southern peripheryof the West Siberian Petroleum Basin.
