(54) Title
(EN) FLOW CONTROL DEVICES WITH PRESSURE-BALANCED PISTONS
(57) Abstract
(EN) --

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.
