Abstract: 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.

Abstract: 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 cyclonic solids separator connected between the pump and the velocity tube assembly. The cyclonic solids separator includes a housing, a discharge manifold extending through the housing, and a plurality of ejection ports that extend through the discharge manifold along arcuate, tangential paths.

Abstract: A pump that is configured to lift fluids through a tubing string includes a gas mitigation system and a screen flush module. The gas mitigation system has a canister with an interior and an intake screen. The gas mitigation system further includes an intake tube that extends into the canister. The screen flush module is configured to flush solids particles trapped in the intake screen.

Abstract: 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.

Abstract: A gas mitigation system for use in connection with a subsurface pump includes a shroud hanger that has one or more orifices that permit the passage of fluids through the shroud hanger. A canister connected to the shroud hanger has an open upper end. An intake tube connected to the tubing string extends into the canister. The canister is sized and configured to cause fluids passing around the outside of the canister to accelerate, thereby encouraging the separation of gas and liquid components. The open shroud hanger and open upper end of the canister allow heavier liquid components to fall into the canister, where the liquid-enriched fluid can be drawn into the subsurface pump.

Abstract: A collapsible packer for use in a well includes a deployment assembly, a retraction assembly and a sealing assembly extending between the deployment assembly and the retraction assembly. The deployment assembly may include a spring and a degradable stop configured to offset the force applied by the spring. The degradable stop can be manufactured from a material that dissolves when contacted by fluid in the well. The retraction assembly may by hydraulically or spring energized.
