Application of a dipole-electrical sounding with induced polarization for the exploration natural deposits of bitumen and high-viscosity oil inthe Republic of Tatarstan

Authors: D.I. Khassanov, K.I. Brednikov, B.G. Chervikov (Kazan (Volga Region) Federal University, RF, Kazan)

Key words: dipole electro sounding, electrical resistivity tomography, induced polarization, Ufimian facies.

The article presents the results of the application of a dipole-electrical sounding with induced polarization (DES-IP) for the exploration of natural deposits of bitumen and high-viscosity oil. The field work was carried out with multiple data overlapping. It's allowed us to construct geoelectrical sections with high resolution in lateral and vertical direction. The results indicate the prospectivity of the method DES-IP for the study of deposits of natural bitumen, and high-viscosity oil. The method DES-IP has higher performance as compared to vertical electrical sounding method. This method is more adapted to work with signal of high man-made electromagnetic noise. After data set interpretation the location of bitumen deposits become more accurate.
