Abstract
The fundamental geophysical method of searching for oil deposits on the territory of the Volga-Urals region is seismic exploration; however, one should not underestimate the reliability of simple geophysical methods, such as gravel and
magnetic exploration, when predicting oil and gas deposits in the studied area. In the present work, the analysis revealed certain spatial relationships of geophysical parameters with the presence of hydrocarbon deposits in the lower floors (upper devon, lower carboniferous) of the sedimentary cover of the Volga-Ural oil and gas-bearing province: most of the traps are located in the zones of positive values of the anomalous magnetic field and in the zones of negative values of the local magnetic field.

Materials and methods
Complex interpretation of data obtained by methods: magnetic exploration (field ΔТа), engraving (field Δg) together with seismic exploration data.
