Description. Electrometric study of oil and gas wells filled with leading drilling fluid (fluid resistivity < 2 Ohm m). Allows detection of reservoirs in vertical, deviated and deviated-horizontal wells; to set the value of the specific resistance of the part of the reservoir undamaged by the drilling fluid, the diameter of the zone of penetration of the drilling fluid from its supports.
