Patent ID: 8037940

Claim:
A method of completing a well comprising: installing in a downhole tubing a plurality of retrievable flow control devices where each retrievable flow control device of the plurality corresponds to one of a plurality of formation zones, wherein each retrievable flow control device comprises an engaging protrusion which engages directly with a profile formed in the downhole tubing such that the retrievable flow control device spans the entire internal diameter of the downhole tubing; establishing communication between a flow control device port of each retrievable flow control device and a corresponding completion port regardless of the rotational orientation of the retrievable flow control device relative to the completion by placing the flow control device port of each retrievable flow control device in a concentric groove; producing fluid from the one or more formation zones or injecting fluid into one or more formation zones via the flow control device port of each retrievable flow control device and the corresponding completion port; monitoring a well parameter from each of the one or more formation zones; and retrieving at least one of the one or more retrievable flow control devices and replacing the at least one flow control device with another retrievable flow control device based upon the monitoring results.
