Abstract
An annular hanger seal for sealing a tubing or casing hanger comprising a flow passage, at least one seal chamber, and a metal surface. Pressure can enter the hanger seal through the flow passage causing the at least one seal chamber to expand. Expansion of the at least one seal chamber can cause sealing contact between the metal surface around the at least one seal chamber and the housing, the hanger, or both surfaces. The seal can later be punctured or otherwise depressurized to break sealing contact for removal of the hanger from the annular space.
