The Geological Process Modelling (GPM) module developed for the Petrel software package enables digital modelling of natural processes of erosion, transportation and deposition of clastic sediments. Modelling of cones of removal was carried out for Achimov strata of the Western Siberia field. The results obtained characterize the expected sediment geometry, lithology distribution due to sea level changes, paleogeography, paleoclimate, tectonics and sediment input rates. The results allow the evaluation of different options and enable us to predict the distribution of prospective oil and gas bearing sediments in areas where no wells have been drilled. As a result, a sedimentation model was obtained, which reflects the formation of the elements of the sedimentation system of the study area. According to the sedimentation model, the main facies zones of the turbidite sediments under consideration are identified. [ABSTRACT FROM AUTHOR]

The Timan–Pechora oil and gas province (TPP), despite the good geological and geophysical knowledge of its central and southern regions, remains poorly studied in the extreme northwestern part within the north of the Izhma–Pechora depression and the Malozemelsk–Kolguev monocline, and in the extreme northeast within the Predpaikhoisky depression. Assessing the oil and gas potential of the Lower Paleozoic part of the section is urgently required in the northwestern part of the TPP, the productivity of which has been proven at the border and in the more eastern regions of the province (Pechora–Kolva, Khoreyverskaya, Varandei–Adzva regions), that have been evaluated ambiguously. A comprehensive interpretation of the seismic exploration of regional works was carried out, with the wells significantly clarifying the structural basis and the boundaries of the distribution of the main seismic facies' complexes. The capabilities of potentially oil- and gas-producing strata in the Silurian–Lower Devonian were studied. An analysis of migration routes in transit strata used for basin modeling in order to reconstruct the conditions of oil and gas formation that are common in the land and water areas of the Arctic zone of the TPP was carried out. Modeling allowed us to reach an understanding of the formation of large zones with possible accumulations of hydrocarbons, including the time at which the formation occurred and under what conditions, to establish space–time links with possible centers of generation to identify migration directions and, based on a comparison with periods of intensive generation of hydrocarbons both directly located within the work area and beyond (noting the possible migration), to identify zones of the paleoaccumulation of hydrocarbons. The body of existing literature on the subject made it possible to outline promising oil and gas accumulation zones, with the allocation of target objects for further exploration in the Lower Paleozoic part of the section.
