Northern segment of Urals foredeep: petroleum potential of suture zones

The suture zones of the northern segment of the Urals Foredeep are complex structural and tectonic formations with low exploration maturity and, at the same time, highly promising in terms of prospecting for new oil and gas deposits. In the article, petroleum potential of the Chernyshev and Chernov suture zones are substantiated on the basis of tectonodynamic, lithofacies and geochemical analyses. Structural-tectonic analysis made it possible to identify the high-priority objects for prospecting and exploration, including: autochthon of the Khosedayu - Neruyu swell, the East Vorgamusyur and Povarnitsky fault-line structures, the Yunyaginsky reef object, the eastern part of the Chernov horst. Lithofacies rock associations and natural reservoirs formed in the Paleozoic time in the passive margin of the East European Platform are characterized by the presence of sedimentary porous-cavernous reservoirs in reefs, as well as secondary hypergene and tectonodynamic cavernous and fractured reservoirs. The geochemical environment contributed to hydrocarbon accumulation in the suture zones most elevated in relation to the kitchen areas. Based on the analysis of petroleum potential of the Chernyshev and Chernov suture zones, recommendations are given for further exploration and prospecting of these unique geological objects
