The Baltic region is one of the most studied oil basins in Russia, where fields are currently being developed, but there are a number of unresolved issues concerning the evolution of the sedimentary section and the formation of reservoirs of the Cambrian-Ordovician oil complex. The purpose of this work is to perform basin modeling to build digital models of the evolution of the sedimentary basin, as well as the generation, migration and accumulation of hydrocarbons within the Baltic oil region. To construct a correct basin model, parameters such as the lithological composition of rocks, geochemical characteristics of oil and gas source rocks, and thermal characteristics of the section were determined. As a result of basin modeling, the most probable volumetric models of generation, migration and accumulation of hydrocarbons in the studied section were obtained, which enables to trace the stages of the beginning of oil and gas generation, assess the maturity of oil and gas source rocks, and trace the patterns of distribution of hydrocarbon deposits over the area of the studied region. The selected parameters and boundary conditions are correct, and the obtained results are in good coherence with the drilling data and can serve as a basis for more detailed basin modeling. The modeling results enabled to confirm the oil potential of the study area at the regional level, as well as to determine priority areas for further geological exploration work.
