Flow control device and methods for using same
Abstract:
A fluid flow control apparatus includes a biasing member applying a biasing force to a closure member, and a sealing member receiving the closure member. A dampener operatively connected to the closure member resists a force applied to the closure member. A fluid seal is formed when the biasing member presses the closure member against the sealing member. The closure member and sealing member may cooperate to control fluid flow along a fluid conduit formed in a wellbore tubular. The apparatus may include an actuator that controls the force applied to the closure member. The actuator may adjust the biasing force, and/or the dampening force. Also, a controller control the actuator may be responsive to a signal generated at a surface location, a downhole location, and/or a signal generated by a sensor.
