Abstract:
Provided are systems and methods for controlling the fluid flow to and from the flow ports of an autonomous inflow control device (AICD). Features may include the addition of a ball check valve to the AICD. A well system may comprise: a production tubing; a flow control device, wherein the flow control device is disposed onto the production tubing; and a ball check valve disposed between the flow control device and the production tubing to restrict flow into the production tubing through a port in the flow control device, wherein the ball check valve comprises a housing and a ball.
