The paper presents and analyzes the results of the experimental application of the mobile method of remote sensing data (RS) processing and non-traditional geoelectric methods of the forming a short-pulsed electromagnetic field (FSPEF) and vertical electric-resonance sounding (VERS) at the area of a known hydrocarbon deposit location. Additional investigations at the “Zapadnoye” oilfield (Ukraine) have been carried out with the aim of selecting the directions of inclined boreholes drilling from two drilled vertical wells. The materials of the performed studies show that mobile and direct-prospecting methods can be successfully applied for additional exploration of hydrocarbon deposits that are decommissioned or at a late stage of development. The method of RS data processing and the areal FSPEF method of survey can be used for the anomalies of the "reservoir of gas (oil)" type detecting and mapping and for the areas with higher values of reservoir pressure in the collectors allocating within anomaly boundaries. The bedding depths and thicknesses of the anomalous polarized layers (APLs) of “gas (oil)” type are determined by VERS sounding.
