The results of experimental application of mobile method of remote sensing (RS) data processing and nontraditional geoelectric methods of forming short-pulsed electromagnetic field (FSPEF) and vertical electric-resonance sounding (VERS) on the prospecting area around the known deposits of hydrocarbons (HC) are given. They show that mobile methods can be successfully applied for the hydrocarbon deposits exploration, that are decommissioned or at the late stage of development. The method of RS data processing and the areal FSPEF method survey can be used for the anomaly 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 (APL) of “gas (oil)” type are determined by VERS sounding. The same techniques can also be used for the hydrocarbon accumulations searching in unconventional reservoirs – coal-bearing and crystalline rocks, shales, tight sandstones. The broad application of mobile operative technologies at various stages of different type hydrocarbon accumulations prospecting will accelerate and optimize the exploration process in generall.
