Numerous studies of Upper Devonian deposits in the Volga-Urals Province and, in particular, in the South Tatarsky Arch, resulted in identification of formations containing carbonaceous domanik-type deposits and their layer-by-layer lithological and geochemical characteristics. Commercial oil content in these deposits was revealed in the column of 444 Pool in the Berezovsky area; it was approved by FSFI State Reserves Committee and put on the State Balance Sheet. In 2018, oil inflow from the interval of the Mendymsky-Domanikovy domanik-type deposits was obtained in open hole when drilling exploratory well #21159 in the North Altetievsky area of the Romashkinsky field. Core was later taken and studied, wide well logging was performed, and 7.5 m3/day oil inflow was obtained in 318 long horizontal sidetrack after acid pumping. Results of well studies were considered together with the previously conducted analysis of oil and gas bearing capacity of the domanik-type rocks in Tatarstan territory. The authors present the results of core studies, well logging and testing; they draw conclusions on the potential of the domanik-type deposits in the context of resources and reserves growth with further development of these deposits in Tatarstan territory in the Volga-Urals Province as a whole.
