The article has been prepared by specialists from Rosneft Oil Company and the Reservoir and Petroleum Engineering Department of RN-Shelf-Arctic LLC, a subsidiary of Rosneft which carries out geological research and hydrocarbon exploration within the Rosneft’s license blocks upon the Arctic and Far Eastern shelves of the Russian Federation. The article provides an overview of structure and depositional environments of the Permian clastic deposits within the marine extension of the Kolvinsky megaswell. There are large oil fields (Vozeiskoye, Kharyaginskoye, Yuzhno-Khylchuyuskoye) within onshore part of this vast area of oil and gas accumulation. These fields have wide stratigraphic range of oil-bearing capacity from the Lower Devonian to the Triassic. The importanсе of this research is associated with the proven petroleum potential of the Permian deposits within Timan-Pechora petroleum basin. Generalization of the previous results and comprehension with new detailed 3D seismic interpretation allowed the authors to: 1) detail the geological structure and depositional environments of the Permian clastic deposits; 2) identify and map the most perspective deposits that can be considered as a potential hydrocarbon reservoir; 3) reduce geological uncertainties associated with the presence and quality of the Permian clastic reservoir. The article is based on the results of interpretation of 3D and 2D seismic data, geological and geophysical data of adjacent areas, as well as regional geology of the Pechora Sea.
