摘要： A wellhead seal assembly that forms a metal-to-metal seal between inner and outer wellhead members and a face seal between inner wellhead members. The face seal is created by two opposing sealing surfaces on inner wellhead members that sealingly engage each other. The inner wellhead members that interact to form a face seal may be a casing hanger, bridging hanger, or lockdown hanger. A wicker profile formed on one of the opposing seal surfaces bites into the opposing seal surface in response to a load. The face seal is designed such that well pressure enhances the face seal.

摘要： A wellhead housing has a casing hanger with an actuator mechanism to provide for direct transfer of casing and pressure loads to the housing even in conditions where the casing hanger may be set in a high position in the wellhead housing on a load shoulder, or in a casing hanger in the wellhead housing for an earlier installed, larger diameter casing string.

摘要： A wellhead housing has a telescoping casing hanger with an actuator mechanism to provide for direct transfer of casing and pressure loads to the housing. The transfer of casing and pressure loads occurs even in conditions where the telescoping casing hanger may be set in a high position in the wellhead housing on a load shoulder. The transfer of casing and pressure loads also occurs in conditions where the telescoping casing hanger may be set in an earlier installed casing hanger in the wellhead housing for a larger diameter casing string.
