摘要： A wellbore system comprising a housing assembly and a hanger assembly. The hanger assembly comprises an actuation member that interacts with a portion of the housing assembly when the hanger assembly is positioned at a desired location in the housing assembly. The hanger assembly also comprises a load member that is adapted to extend between the hanger assembly and the housing assembly to enable the housing assembly to support the hanger assembly. The load member is carried into the wellbore in a retracted position. When the actuation member interacts with the housing assembly at the desired location, the actuation member actuates the load member to expand outward to extend between the hanger assembly and the housing assembly. The actuation member is adapted to transfer a lifting force from the surface to the load member to enable an over-pull test of the hanger assembly to be performed.

摘要： A wellhead system comprising an outer wellhead housing, an inner wellhead member, and an annulus therebetween. The inner wellhead member, such as a casing hanger, is adapted to land in the outer wellhead housing. The outer wellhead housing may comprise a wickers formed in a hardened metal inlay. Alternatively, or in addition to the wickers formed in the outer wellhead housing, wickers may be formed in a hardened metal inlay in the inner wellhead member. An annular metal seal may be disposed in the annulus and driven into the wickers to seal the annulus between the inner wellhead member and the outer wellhead housing and to axially restrain the seal within the annulus.

摘要： A wellhead system comprising a seal with a restraining member adapted to cooperate with a housing to restrict axial movement of the seal. The seal is adapted to form a seal between the housing, such as a wellhead, and a tubular member, such as a casing hanger. The seal has a latch ring that is expanded outward as the seal is installed within the wellhead. Axial movement of the seal is restricted by engagement between the expanded latch ring and the inner profile of the housing. The seal and housing may be adapted so that a portion of the seal is received by a recess in the inner profile of the housing.

摘要： A well system comprising a tubular housing, a hanger assembly, and a load member disposed in a recess within the central bore of the housing to support the hanger assembly from the housing. The recess and the load member are configured so that a greater portion of the area of the load member extends into the central bore of the housing as the load member is moved axially in a first direction within the recess.

摘要： A high capacity running tool sets and internally tests a casing hanger packoff during the same trip. The running tool has a stem and a body. The body is secured by threads to the stem of the running tool so that rotation of the stem relative to the body will cause the stem to move longitudinally. An engagement element connects the tool body to the casing hanger by engaging the inner surface of the casing hanger. Longitudinal movement of the stem relative to the body moves the engaging element between inner and outer positions and lines up ports in the stem and in the body for setting and testing functions.

摘要： A seal assembly between a wellhead housing and a casing hanger, has an inner seal leg for sealing against hanger, and an outer seal leg for sealing against housing. An extension extends downward from the outer seal leg and is connected to a nose ring. The nose ring has a downward facing shoulder that rests on the hanger shoulder to provide a reaction point for setting operations. A sealing surface on the seal legs is heat treated to obtain a lower localized yield strength to provide improved sealing while maintaining mechanical load capability.

摘要： A running tool sets a casing hanger packoff and ensures that the packoff is not pressure tested unless the proper setting stroke was made by the running tool. The running tool has a stem, an inner body, and a piston. The inner body is connected to the stem so that rotation of the stem relative to the inner body will cause the stem to move longitudinally. The piston is connected to the stem so that the stem and piston rotate and move longitudinally in unison. A test slot is located in the outer surface of the inner body. A limit pin is connected to the piston and is adapted to engage the test slot when the piston moves longitudinally relative to the inner body. The stem has a raised profile on a portion of its exterior surface.
