Patent 8186444 was granted and assigned to Schlumberger on May, 2012 by the United States Patent and Trademark Office.
A system that is usable with a well includes a tubing string that extends into an isolated zone of the well and a plurality of chokes modules that are disposed in the isolated zone to control communication between a passageway of the tubing string and the zone. Each choke module includes an associated choke, which is removable from the choke module without disassembly of the tubing string. Each choke module is independently controllable relative to the other choke module(s) to selectively enable and disable flow through the associated choke.
