Water sensitive adaptive inflow control using couette flow to actuate a valve
First Claim
1. An apparatus for controlling a flow of a fluid into a wellbore tubular in a wellbore, comprising:
- a port aligned with an opening in communication with a flow bore of the wellbore tubular;
a first member operatively coupled to the port;
a biasing element applying a biasing force to the first member; and
an outer member positioned along the wellbore tubular and being separated from a wellbore wall by an annulus receiving the first member, wherein the outer member and the first member define a flow space having at least one dimension selected to cause a Couette fluid flow that applies a drag force to the first member that opposes the biasing force.

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.

9. A method for controlling a flow of a fluid into a wellbore tubular in a wellbore, comprising:
-
conveying the fluid from the formation into a flow bore of the wellbore tubular through a flow space in communication with a port that can be selectively aligned with an opening in the wellbore tubular; applying a biasing force on a member associated with the port as fluid flows through the opening; and applying a drag force on the member to align the port and opening and to keep the port aligned with the opening when mostly oil flows through the flow space. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An apparatus for controlling a flow of a fluid into a wellbore tubular in a wellbore, comprising:
-
an outer member positioned along the wellbore tubular and being separated from a wellbore wall by an annulus; and a flow control member coupled to the outer member, the flow control member having an open position and a closed position, wherein moving from the open position to the closed position reduces fluid flow into an opening in communication with a bore of the wellbore tubular, wherein a space between the flow control member and the outer member has at least one dimension selected to cause a Couette fluid flow that generates a drag force to move the flow control member to the open position and to keep the flow control member in the open position. - View Dependent Claims (17, 18, 19, 20)
