Abstract
The experimental results on practical application in 2009 of non-traditional geoelectric methods of forming a short-pulsed electromagnetic field (FSPEF) and vertical electric-resonance sounding (VERS) during the oil and gas searching within the zone of permafrost development are discussed. The additional and independent information, operatively obtained by these methods, can be used when the optimal location of prospecting well determining within the investigation site. Results of experiments show the feasibility of FSPEF and VERS methods application for the operative solving the oil and gas prospecting problems in complex geological and tectonic conditions of the Siberian platform, and is another strong argument in favor of the feasibility of wider use of FSPEF-VERS technology in the process of geological exploration for oil and gas. Established by geoelectric measurements the robust correlation between local uplifts, decreasing of the frozen layer and increasing of melt water thickness under the frozen layer can be considered as "a direct hydrocarbon indicator" (DHI).
