The task of both IP effect and electromagnetic phenomena related to media conductivity cojoint study by means of the time-and-frequency high resolution electrical survey (HRES-IP) technology has been solved.On the basis of 3D modeling, substantiation has been obtained of hydrocarbon deposits appearence within the range of frequency-time electrical survey parameters. A geoelectrical model of the oil deposit has been suggested and comparison of modeling calculations with the observed practical results has been performed. It has been demonstrated that increase of the induced polarization in the OWC vicinity and resistivity anisotropy of the layer which contains the deposit is a direct search property of oil reservoir
