Abstract

A system is disclosed as including an enclosed space within a seal for sealing an area between a hanger and a housing of a wellhead. The enclosed space traverses a first section of the seal, a middle section of the seal, and an opening at a second section of the seal. A port is provided as accessible from the housing. A tool positions the seal within the hanger and the housing so that the port is able to access the enclosed space from the housing to the hanger. A pressure applicator applies fluid into the port at a pressure, which is monitored to determine integrity of the seal. In a monitoring mode, a pressure is monitored at the port. A change in the pressure from an ambient pressure at the port may indicate an on-going issue with the seal. Methods applied to the system are also disclosed.
