The question of the effectiveness of application of the electric centrifugal pumps with submersible electric motor casing is considered. Various variants of installation of the pump below the perforated interval are presented. Their detailed comparison is carried out. The new mechanistic model, that allows to evaluate the effectiveness of reverse natural separation, is used. A map of the applicability of pumps with submersible motor casing is constructed. Areas of application of the technology of their lowering below the perforated interval are determined. The comparison with traditional technologies is given.
