Abstract: An annular seal for installation in an annular groove defined at an interface between first and second wellhead component is disclosed. The seal has an annular body with first and second legs that define an annular channel at the inside diameter face of the annular body. The annular channel is configured to define a pressure cavity within the annular groove between the first and second wellhead component. The outside diameter face of the annular body has a tapered profile in cross-section, and the first and second legs have enlarged ends configured for engaging the inside diameter wall of the annular groove.

Abstract: A highly elastic annular seal assembly includes a metal stabilator having inner and outer spaced-apart and projecting annular plates coupled to a common base and forming a U-shaped geometry, and a metal seal ring having inner and outer spaced-apart and projecting annular plates coupled to a common base and having a U-shaped geometry with a central groove. The stabilator plates are configured to be disposed within the central groove between the seal ring plates, and the stabilator plates being configured to gradually urge the seal ring plates outward as the seal ring and stabilator are brought together until a portion of the first seal ring plate contacts and forms a seal against a mating body disposed within the first seal ring plate.

Abstract: A pressure-energized bidirectional seal having a main body having a first end and a second end and a pair of legs extending from the second end of the main body, the pair of legs having an inner surface and an outer surface, the inner surface forming a hollow interior opening in a first direction. The bidirectional seal includes at least one rib extending from the outer surfaces and configured to sealingly engage a mating surface of a mating body the at least one rib forming a sealing zone opening in a second direction opposite of the first direction.
