Proposes a method and a device for electromagnetic examination of electrically resistant objectives potentially containing Hydrocarbon deposits. The proposed method and the device are characterized by a High Sensitivity to targets containing hydrocarbons and an ability to work in shallow and Deep Water.The Apparatus includes a Transmitter provides current pulses in water (2) through a Wire transmitter, vertical or horizontal Submerged (7a, 7b, 8) and a registration subsystem (9) connected to electrodes (11) receptors in the vertical or horizontal wires (10a, 10b).The transmitter generates a sequence of impulses with precise termination of the Electric Current, the electric field is measured in water in breaks between these impulses. The straight line through the receptor electrode is in the same vertical plane as the ends of the cable Transmitter (7a, 7b).The measurements were carried out with a separation between the cable Transmitter (7a, 7b) Receptors and cables (10a, 10b) which is smaller than the depth of the Oil Reservoir Target, measure from the bottom of the Sea (3).
