ABSTRACT:
A retrievable flow control device comprising a housing configured to sealably couple with a completion component. The housing may comprise a first port and a second port establishing a fluid pathway. The fluid pathway may regulate a fluid flow as the fluid flow passes through the fluid pathway. The housing may further comprise a coupling mechanism configured to releasably couple with a corresponding feature of the wellbore completion. The downhole flow control device may be configured to be retrievable independently of the completion component. The flow control device may comprise a check valve in the fluid pathway in order to substantially constrain the fluid flow to a single direction. In some cases, the flow control device may be configured to couple with a side pocket. In other cases, a concentric flow control device may be configured to couple with a screen base pipe, tubing, or stinger.
