Abstract:
An apparatus for controlling fluid flow into a wellbore tubular includes a flow control member that selectively aligns a port with an opening in communication with a flow bore of the well bore tubular. The flow control member may have an open position wherein the port is aligned with the opening and a closed position wherein the port is misaligned with the opening. The flow control member moves between the open position and closed position in response to a change in drag force applied by a flowing fluid. A biasing element urges the flow control member to the open or the closed position. The apparatus may include a housing receiving the flow control member. The flow control member and the housing may define a flow space that generates a Couette flow that causes the drag force. The flow space may include a hydrophilic and/or water swellable material.
