  • Patent number: 10246964
    Abstract: A system includes a housing of a wellhead, a hanger configured to be positioned within the housing of the wellhead, and a hanger retention system. The hanger retention system includes a key-slot interface having at least one retention segment configured to move between a collapsed position in which the at least one retention segment does not block movement of the hanger relative to the housing of the wellhead and an engaged position in which the at least one retention segment engages at least one corresponding slot to block movement of the hanger relative to the housing of the wellhead. The at least one retention segment includes a wavy cross-sectional shape at least while the at least one retention segment is in the engaged position that enables the at least one retention segment to move between the collapsed position and the engaged position.

  • Patent number: 10233714
    Abstract: A wellhead hanger assembly is provided. In one embodiment, a system includes a wellhead hanger, a running tool coupled to the wellhead hanger, and a torque sleeve positioned to transmit torque from the running tool to the wellhead hanger. The running tool can be in castellated engagement with the torque sleeve via a first set of castellations and mating slots, and the wellhead hanger can be in castellated engagement with the torque sleeve via a second set of castellations and mating slots. Additional systems, devices, and methods are also disclosed.

  • Publication number: 20180258727
    Abstract: A system includes a running tool having a tool body configured to couple to a hanger assembly, a first sleeve disposed around the tool body and configured to move in an axial direction with respect to the tool body, a torque sleeve disposed around the tool body and configured to move in the axial direction as a result of movement of the first sleeve in the axial direction, where the torque sleeve has a first torque transfer interface configured to interlock with a second torque transfer interface of the hanger assembly to enable torque transfer from the running tool to the hanger assembly, and a second sleeve configured to couple to the first sleeve, where the second sleeve is configured to move to engage a lock member of the hanger assembly and to move the lock member between a locked position and an unlocked position.

  • Publication number: 20170152721
    Abstract: A system includes a hanger locking assembly configured to lock a hanger within a housing of a wellhead. The hanger locking assembly includes an energizing ring having one or more axially-extending passageways configured to receive and to support one or more control lines. An anti-rotation element extends between the energizing ring and the hanger to block rotational movement of the energizing ring relative to the hanger. A locking ring is in contact with the energizing ring, and axial movement of the energizing ring relative to the hanger drives the locking ring radially to engaged position in which the locking ring extends into a corresponding recess of the housing of the wellhead to block axial movement of the hanger relative to the wellhead.

  • Patent number: 9273531
    Abstract: A subsea wellhead assembly includes a production tree and a tubing hanger assembly having a tubing hanger and an orientation adapter. A passage is formed through a side wall of the orientation adapter for porting communication from within a main bore of the wellhead assembly. When the tubing hanger assembly lands in the wellhead, a key on the orientation adapter engages a helical profile on an inner surface of the main bore and rotates the orientation adapter so that the passage registers with a passage in the tree. Fluid and electricity communicates through the registered passages. Examples of connectors between the respective passages include spheriseal connectors and electrical wet connects.

  • Patent number: 8851182
    Abstract: A well production system including a wellhead and a first casing string supported from a first casing hanger landed on a shoulder in the wellhead bore. A loading shoulder assembly is installable in the wellhead and includes an energizing ring, a loading ring threaded into the interior of the energizing ring, a lock ring, and a hold-down ring threaded into the interior of the loading ring. The hold-down ring engages the first casing hanger to prevent rotation of the hold-down ring and restrain rotation of the loading ring. The lock ring is expandable from an unset position into supporting engagement with the wellhead in a set position upon rotation of the energizing ring. The hold-down ring is also moveable axially out of the loading ring to restrain the first casing hanger.
