摘要： A submersible pumping system for producing a fluid from a wellbore through production tubing to a wellhead includes a motor controlled by a motor drive, a pump driven by the motor, and one or more downhole sensors configured to measure conditions at the motor and pump. An intake fluid density control system has a control fluid reservoir positioned above the pump that is configured to release a density control fluid to the intake of the pump under the force of gravity. The release of the density control fluid can be controlled by a dump valve that automatically moves between open, closed, and intermediate positions in response to a control signal based on measurements made by the downhole sensors or motor drive.

摘要： A pumping system is configured to be deployed in a well that has a vertical portion and a lateral portion. The pumping system includes a pump positioned in the vertical portion, a velocity tube assembly that extends from the vertical portion into the lateral portion and a multiphase diverter connected between the pump and the velocity tube assembly. The multiphase diverter includes a housing and a plurality of ejection ports that extend through the housing at a downward angle.
