The presence of hydrocarbons in the ancient Precambrian Strata was rst established within the Siberian Platform. A signi cant amount of drilling of deep parametric wells and a detailed study of geological and geophysical materials of deep wells made it possible not only to establish oil and gas shows, but also led to the discovery of elds. The article presents the history of the search and study of Precambrian oil on all ancient platforms. After the discovery of a number of large oil elds in the Paleozoic sediments of the East-European Platform, special attention of researchers was directed to the study of the Riphean aulacogens as promising prospecting objects for hydrocarbons. In connection with the need to replenish the mineral resource base, researchers are solving the issues of searching for hydrocarbons in carbonate sediments. Studies have shown that it is carbonate rocks that have good reservoir properties. The article examines the carbonate strata of the Shikhan and Leuza Formations of the Abdulinskaya Series of the Upper Riphean, penetrated by deep wells in the Preuralian Foredeep on the eastern edge of the Russian Plate.
