CA 2328666

The wellhead system includes a tubing spool, adapted for mounting on a subsea wellhead, and a tree assembly connected to the top of the tubing spool. The tubing spool and tree assembly include a concentric production flowbore extending therethrough. The tubing spool includes an annulus circulation flow path extending around the tubing hanger disposed in the tubing spool and another annulus circulation flow path extending around the production master and swab valves in the production flowbore of the tree assembly. Thus, annulus access is provided through the wellhead system by an internal flow path, and the annulus circulation flow paths may be disposed completely within the wall of the tubing spool and tree assembly. Further, during installation or workover, annulus access may extend to the surface by a spoolable conduit.
