Description. Electrometric study of oil and gas wells filled with non-conductive drilling fluid (fluid resistivity >1 Ohm m). Helps: identify reservoirs in vertical, deviated and deviated-horizontal wells; 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 resistance.
