Orientation-less ultra-slim well and completion system |
摘要 |
An assembly for landing a tubing hanger in a subsea well includes a riser extending from a subsea wellhead assembly to a vessel at the surface of the sea. A tubing hanger having a string of tubing suspended therefrom is lowered through the riser with a string of conduit, and the tubing hanger lands within the subsea wellhead assembly. A sensor is positioned adjacent the subsea wellhead assembly to monitor the axial position of the tubing hanger within the subsea wellhead assembly. The sensor also communicates the axial position of the tubing hanger to the surface. A locking mechanism is carried by the tubing hanger and is selectively operable to lock the tubing hanger in place relative to the subsea wellhead assembly when the tubing hanger reaches a predetermined axial location.
