In geological terms the section of the Kovykta gas condensate field and the surrounding areas is composed by three geoelectric complexesthe post-salt terrigenouscarbonate; carbonatehalogen; and the pre-salt terrigenouscarbonate, lying at the basement. Within the two lower complexes reservoir horizons are spread regionally, with some of them bearing commercial hydrocarbon deposits. Due to the presence of conductive saline pore solutions, the reservoirs are characterized by low electrical resistivity. This leads to the geological effectiveness of the use of electromagnetic methods in the delineation of the zones of reservoir development.
