In 2011 and 2012 insitu electromagnetic soundings using the industrial power transmission line «Urengoy-Pangody» were taken in the Yamal-Nenets Autonomous District (YaNAD). They were conducted both in the field of the extralow frequencies (ELF) antenna «Zeus» located on the Kola Peninsula and in the fields of the natural sources (AMT-MT). Conductive layers were installed at depths of a few hundred meters and more than 1 km. These layers were linked with changes in lithology, porosity and fluid saturation of rocks. The research results showed perspectivity of complex electromagnetic sounding with natural and powerful controlled sources to find gas and oil promising horizons at a depth in the sedimentary cover of the West Siberian platform in the YaNAD.
