Abstract:
1. A well completion system for controlling and monitoring multiple annuluses in a well, the well having production tubing string, a production casing string surrounding the production tubing string and defining an “A” annulus therebetween, and an intermediate casing string surrounding the production casing string and defining a “B” annulus therebetween, the well completion system comprising: a tubing hanger suspension assembly including the production tubing string and a tubing hanger housing having a tubing hanger lower assembly, the tubing hanger lower assembly extending around an upper length of the production tubing string and defining a production annulus between the tubing hanger lower assembly and the production tubing string, the tubing hanger lower assembly arranged and designed for insertion within the production casing string; the tubing hanger lower assembly including a seal arranged and designed to provide sealed engagement between the tubing hanger lower assembly and the production casing string, the sealed engagement providing a separated area above the seal outside the lower assembly and inside the production casing string that is segregated from the production annulus, the production annulus remaining in fluid communication with the “A” annulus; a “B” annulus access assembly including at least one port in the production casing string at a location above the seal, and providing access between the “B” annulus and the separated area, the “B” annulus access assembly including a sleeve having an open position and a closed position, the sleeve allowing fluid communication through the at least one port when in the open position, and preventing fluid communication through the at least one port when in the closed position; the tubing hanger suspension assembly including an arrangement arranged and designed to reposition the sleeve from the closed position to the open position, thereby allowing the “B” annulus to communicate with the separated area via the at least one port; the tubing hanger housing including “A” and “B” annulus passageways, the “A” annulus passageway in communication with the production annulus and the “B” annulus passageway in communication with the separated area.
