Abstract
Background. The junction zone of the Pre-Ural marginal trough and the West Ural outer folding is conventionally considered as a structure possessing a high hydrocarbon potential. However, the complexity of its geological structure, the ambiguity of interpretation of geological and geophysical materials and, as a result, the lack of reliable geological models restrain the development of its resource base.
Aim. To study the formation conditions of sedimentary basins of the junction zone of the Pre-Ural trough and the West Ural outer folding, to characterize the elements of petroleum systems.
Materials and methods. Both unpublished and published geological, geophysical, and geochemical materials on the study area were used. These materials served as the initial data for conducting a basin analysis and an analysis of petroleum systems.
Results. The following three sub-basins were identified: South Pre-Ural sub-basin, Middle Pre-Ural sub-basin, and North Pre-Ural sub-basin. For each subbasin, the average sedimentation rates and sedimentary cover capacities were calculated; elements of petroleum systems were characterized.
Conclusion. The formation conditions of sedimentary basins were studied. The generation and accumulation petroleum systems, which determine the oil and gas potential of the area under consideration, were identified and described.
