摘要： A wellhead assembly having a wellhead housing, a casing hanger set within the wellhead housing, and sealing areas provided on opposing surfaces of the wellhead housing and casing hanger. The sealing areas circumscribe an axis of the wellhead assembly along respective axial distances on the wellhead housing and casing hanger. A seal is included with the wellhead assembly that has inner and outer legs that respectively engage the sealing areas and form sealing surfaces against the sealing areas. The axial distances of the sealing areas exceeds the length of the inner and outer legs, so that an original seal can be removed and replaced by a secondary seal, wherein the secondary seal engages sealing areas different from the sealing areas engaged by the original seal.

摘要： A hydraulic coupling having a lower tubular member and an upper tubular member for sealing engagement one with the other. The lower and upper members are maintained in axial engagement by an axial load. The lower member and the upper member each have an annular body having an axial bore therethrough for the passage of fluid. A metal, concentric inner annular seal leg and outer annular alignment leg extend from the body of the upper member, defining an annular sealing recess between the seal legs. An annular metal sealing portion or wall extends from the body of the lower member and has an inner diameter that defines a sealing surface for insertion into the sealing recess for sealingly engaging the inner annular seal leg. The sealing recess has a backup elastomer ring, which is axially compressed by the sealing portion. When the couplers are made up, the metal-to-metal seal is achieved due to an interference fit between the coupler halves. Because the seal is a straight-bore seal, the location of the final position of the couplers relative to one another can vary.

摘要： Wellhead assemblies, seal assemblies, and methods of locking down an annulus seal disposed within an annulus between outer and inner wellhead members, are provided. A seal assembly is positioned in an annulus. An energizing member is axially translated downward to energize an annulus seal element and outwardly radially compress a high-strength lockdown member into contact with an inner diameter surface of a wellhead member. The wellhead member can include a set of wickers. During compression, the outer diameter surface of the lockdown member is plastically deformed onto the set of wickers.
