Abstract: A sand control screen assembly includes a base pipe and a flow control device positioned within a flow path for a fluid that extends between the exterior and the interior of the base pipe. The flow control device includes a housing defining an inlet that receives the fluid from the flow path and an outlet that discharges the fluid back into the flow path, and a piston chamber is defined in the housing to fluidly communicate the inlet with the outlet. A pressure-balanced piston is positioned within the piston chamber and movable between a first position, where fluid flow between the inlet and the outlet is prevented, and a second position, where fluid flow between the inlet and the outlet is facilitated. An actuator moves the pressure-balanced piston between the closed and open positions, and an electronics module is communicably coupled to the flow control device to operate the actuator.

Abstract: Some examples can be implemented to determine electric submersible pump efficiency to estimate downhole parameters. At a computer system, a load signal on an in-well type electric submersible pump to transfer fluid through a wellbore is received. At the computer system, a load represented by the received load signal and an expected load on the pump is compared. A difference between the load represented by the received load signal and the expected load based on comparing the load represented by the received load signal and the expected load on the pump is identified.

Abstract: A downhole wellbore isolation tool includes an elastomeric sealing element for engaging a casing member or another tubular member in a wellbore. The isolation tool includes one or more expandable slips for gripping the tubular member and holding the isolation tool in place.

The expandable slips may be constructed of a plurality of slip elements, and the elastomeric sealing element may flow into gaps defined between the slip elements when the isolation tool is set. The slip segments and other components of the isolation tool may be constructed of a dissolvable material to facilitate removal of the isolation tool from the wellbore.
