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.

Based on geological survey data from previous years, it is safe to say that there is a possibility of oil and gas discovery in the Devonian terrigenous-carbonate deposits, similar to the findings in the regions known as the Ryazano-Saratovsky Basin and the Stepnovskaya Anticline, as well as its adjacent areas. Yet the geological structure and a potential for discovery of recoverable hydrocarbon deposits within the Svintsovskaya Depression are still unclear.

Up to the present time the territory of Ryazan-Saratov mega-deflection including dedicated to it Chembarsko-Petrovskaya zone of dislocations for oil and gas remains poorly studied by modern geological and geophysical methods of exploration and deep exploratory drilling. In this paper the characteristic of the geological structure of a complex of Paleozoic rocks and identified deposits and deposits discovered in the Devonian and Carboniferous oil and gas complexes in
