Key words: Sorokin Swell, fault-bounded oil reservoirs, Lower Devonian, new exploration directions.
Based on review of the geological structure, basin history and evolution of hydrocarbon systems of the Varandey-Adzvinskaya zone, the authors made a conclusion of favorable conditions for the fault-bounded traps for oil accumulations at the eastern flank of the Sorokin Swell. The main reservoirs are related to the Lower Devonian formations. The region had several stages with different oil migration paths due to tectonic reconstruction. Structure of the nearby oil fields supports the proposed concept, making a good basis for new exploration directions.
