Is it necessary to use electrical exploration to search for hydrocarbons in Western Siberia

Attempts have been made to add electrical exploration to the works in Western Siberia many years. These attempts usually rely on traditional electrical exploration using traditional loop and horizontal line as sours of electromagnetic fields. Loop and horizontal line are source of TE-polarization electromagnetic field (TE- electrical exploration). Traditional TE electrical prospecting is not all electrical prospecting in our opinion, in Western Siberia only electrical prospecting can be successfully applied with the predominant excitation of the TM-polarization field, i.e. with the presence of a vertical electrical component. Such electrical prospecting can be called TM electrical prospecting. The electromagnetic field is predominantly TM polarized, generated by a vertical line or a circular electric dipole (CED).
