International Classification:

E21B 23/00

US Classification:

166195, 166 891, 277337

Abstract:

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.

US Classification:

166341, 166348, 166368, 166387, 166 853, 277322

Abstract:

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.

International Classification:

E21B 33/04
E21B 43/10
E21B 23/00

US Classification:

166 861, 166208

Abstract:

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.

Assignee:

International Classification:

E21B 43/10

US Classification:

166208

Abstract:

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.
