The territory of the platform of Bashkiria is one of the oldest oil-producing regions of the Volga-Ural oil and gas province. Due to the long-term exploitation of deposits (80 years), hydrocarbon reserves confined to the Paleozoic deposits are reduced annually. One of the ways of reproducing the mineral resource base here is to search for hydrocarbon deposits in the poorly studied interval of the pre-Paleozoic sediments, representing a multi-kilometer stratum of Riphean-Vendian terrigenous-carbonate rocks.
