Pre-Cenozoic basement is broken by tectonic dislocations dividing it into blocks. Zones of dislocations and associated crush zones and intensive fracturing have the best capacitive properties and are mayor oil reservoirs in basement body. Application of tracers established vertical and horizontal hydrodynamic communication of producing zones in crystalline basement. Main oil withdrawals and
