The subsalt sediments of the southern part of the Ural-Volga interfluve are poorly studied by seismic exploration, except for the Imashevskoye, Imashevskoye Yuzhnoye and Novobogatinskoye uplifts, where 2D and 3D work traced reflecting horizons to depths of 8.0 km and identified promising targets in the Lower Permian-Carboniferous-Devonian sediments. Carbonate deposits of the Carboniferous were penetrated by single wells. Most of the drilled wells did not reach the projected depth, and there is a discrepancy between seismic and drilling data. Given the geological risk and high cost of drilling wells 6500m and more deep, it is necessary to clarify the structural features of these sediments on the basis and to map the zones of development of potentially highly productive fracture-hypergene reservoirs in the Paleozoic strata using 3D seismic data.
