A completion joint 100 has two sand control jackets 120A-B connected on each end of an intermediately-mounted inflow control device 130. Both jackets 120A-B communicate with a housing chamber 155 through dedicated open end-rings 140A-B. The basepipe's flow openings 118 are isolated from this housing chamber 155 by a sleeve 160 fitted with flow ports 170. The housing 150 is removable to allow access to the flow ports 170 for pinning to configure the ports 170 open or closed for a given implementation.
