At the present stage, most of the oil fields in the central part of the Volga-Ural oil and gas province, administratively located within the Republic of Tatarstan on the structures of the Melekess Depression, the South and North Tatar Arches, are at a late stage of development. Developed fields are characterized by high depletion of the main productive horizons and increase of hard-to-recover oil reserves. In order to replenish the accumulated oil production, it is required to intensify exploration for less studied horizons, which include, inter alia, the deposits of the Kashirian horizon of the Moscow stage of the Middle Carboniferous. The low degree of study for these deposits is associated with the relative importance of their study when drilling on the Devonian, Lower Carboniferous, and Vereisko-Bashkirian Middle Carboniferous deposits. For the purposeful conduct of geological exploration in the Kashirian horizon, the study of Kashirian oil reservoirs, features of their location, and the structure of oil-bearing rocks is of great importance. The most important direction of research for solving these problems is the typification of Kashirian reservoir rocks according to their reservoir properties, structure and genesis.
