  • Patent number: 11965396
    Abstract: A system includes an electric submersible pump assembly and a control valve assembly. The electric submersible pump assembly transports a fluid in a casing string of a well to a surface location and includes a pump that receives the fluid through a pump intake and vents the fluid through a pump discharge when activated. The electric submersible pump assembly further includes a shaft that is fixed to the pump and extends downhole from the pump. The control valve assembly includes a propeller shaft axially movable along a central axis of the system, a propeller attached to the propeller shaft that pushes the propeller shaft downhole when the pump of the electric submersible pump assembly is active, a shaft coupler that connects the propeller shaft and the shaft of the electric submersible pump assembly, and a stinger that has a conduit for the fluid to flow from the casing string to the pump intake.

  • Publication number: 20240125207
    Abstract: A system includes an electric submersible pump and a flow regulating valve. The electrical submersible pump includes a pump that, when activated, receives a fluid disposed within a production tubing of a well through a pump intake and vents the fluid through a pump discharge to a surface location. The flow regulating valve includes a flow tube that blocks the fluid from entering the pump intake when the pump is inactive, a piston, connected to the flow tube, that moves the flow tube within the flow regulating valve, and a stinger that includes a conduit for the fluid to flow from the production tubing to the pump. The flow regulating valve further includes a spring that positions the piston within the flow regulating valve when the pump is inactive and a plurality of seals that pressure-seal a pressure chamber which houses a pressure force that is to be applied upon the piston.

  • Publication number: 20240125203
    Abstract: A system includes an electric submersible pump (ESP) assembly configured to transport a fluid in a casing string of a well to a surface location. The ESP includes a pump configured to receive, upon activation, the fluid through a pump intake and vent the fluid through a pump discharge; an output shaft extending downhole from and fixed to the pump; and a control valve assembly. The control valve assembly includes a movable core of an electromagnet movable along a central axis of the system; a generator attached to the electromagnet, configured to generate electrical power to pull the movable core in an uphole direction upon activation of the pump of the electric submersible pump assembly; a shaft coupler coupling a generator input shaft and the output shaft; and a stinger having a conduit for the fluid to flow from the casing string to the pump intake.
