New combined well design to protect electric submersible pump from sand flow

Abstract

The paper presents a new well construction in order to eliminate the unpleasant complications associated with the appearance of sand flow in the Electric Submersible Pumps (ESP), which is widely used in oil wells in the final stage of reservoir development. The new design is based on the combination of ESP with a Mixer based on the principle of ejector and centrifugal. The combined well construction limits the ESP to be in contact with the sand flow and prevents potential erosion and other complications. The design was modeled and tested in the laboratory condition. Keywords: field; layer; pump; well construction; sand production; sand separator.
