Abstract
A wellhead assembly including a wellhead housing. The wellhead housing comprises a throughbore having a recessed sealing area and a tubing hanger positioned in the throughbore. A seal is positioned between the wellhead housing and the tubing hanger, the seal being positioned so as to form a gap between the seal and the wellhead housing. The wellhead assembly can further include a seal energizer capable of moving relative to the seal in a manner that forces the seal against the wellhead housing to bridge the gap. A method of installing a tubing hanger into a throughbore of a wellhead housing is also disclosed.
