Reviewed is a system of intrastratal tomography, which enables to monitor the process of oil and gaz reserves depletion, to determine displacement front during water injection, to reveal productive formation areas,not covered by water-flooding. It is stated, that combination of geological-statistical modelling methods together with intrastratal tomography and electric-hydraulic stimulation enables to specify the problem Df residual oil reserves distribution and to solve the problem of encreasing well production capacity.
