To improve the efficiency of geophysical prospecting, the Department of Geophysics of the Faculty of Geology of Saratov State University develops original complexation technology allowing to evaluate the possibilities of identifying promising oil and gas areas by circular thermal-magnetic anomalies, limited to the gradient zones of areas of gravimagnetic complex parameter or geopotential fields anomalies itself. The article presents the experience of applying non-seismic elements of the complex of this technology.
