System and methodology using annulus access valve |
摘要 |
A technique facilitates pressure testing of seals along a tubing hanger, such as a tubing hanger used in a subsea application. In some applications, the tubing hanger is sealed along its exterior with an upper tubing hanger seal and a lower tubing hanger seal. A valve assembly is deployed along a fluid passageway which is routed to the tubing hanger seals. The valve assembly may be selectively actuated to a test position, e.g. a closed position, which enables pressure isolation and pressure testing of the tubing hanger seals. |
