  • Patent number: 10184311
    Abstract: A wellhead assembly has a casing hanger for supporting a string of casing, the casing hanger having an external upward-facing shoulder. A radially movable annular lockdown member is carried on the shoulder for movement between a retracted position while the casing hanger is being run and an expanded position. In the expanded position, the lockdown member is in engagement with a lockdown profile shoulder in a wellhead housing. A casing hanger seal is carried by the casing hanger above the lockdown member. The casing hanger seal has a lower extension that includes a connection leg and a nose ring. The nose ring has a cam surface that engages and moves the lockdown member to the expanded position while the casing hanger seal is being lowered into a set position. Slots are formed in the extension to reduce the axial stiffness.

  • Patent number: 10174574
    Abstract: A wellhead assembly having an insert that is disposed between a wellhead housing and casing hanger. Axial slots through the insert define a flow path between the wellhead housing and casing hanger. The insert is made from a higher strength material and supports a load exerted between the casing hanger and wellhead housing. The insert is a ring like member, and the slots can more easily be machined in the insert than in the wellhead housing.

  • Publication number: 20170328138
    Abstract: A tubular member connection system includes a box having an inner diameter surface and internal box threads. A pin has an outer diameter surface and external pin threads, the pin threads shaped to mate with the box threads to releasably secure the pin to the box so that the pin and the box are aligned along a common central axis. A slot is located in one of the inner diameter surface and the outer diameter surface, the slot having a pair of sidewalls. An anti-rotation profile is located in the other of the inner diameter surface and the outer diameter surface. A key is sized to fit within the slot and have a key profile shaped to engage the anti-rotation profile and prevent relative rotational movement between the box and the pin.

  • Patent number: 9797214
    Abstract: A wellhead assembly has a casing hanger for supporting a string of casing, the casing hanger having an external upward-facing shoulder. A shoulder ring is mounted on the shoulder. A radially movable annular lockdown member is carried on the shoulder ring for movement between a refracted position while the casing hanger is being run and an expanded position for engaging an interior surface of a wellhead housing. A casing hanger seal is carried by the casing hanger above the lockdown member. The casing hanger seal has a nose on a lower end that engages and moves the lockdown member to the expanded position while the casing hanger seal is being lowered into a set position. The shoulder ring is formed of a material of greater yield strength than the shoulder. Flow channels between the shoulder and the shoulder ring assist in flowing debris from above the shoulder to below.

  • Patent number: 9765588
    Abstract: A wellhead assembly includes a wellhead housing having a bore and a locking profile including a gallery slot, and an annular notch. An inner wellhead assembly is selectively landed in the bore of the wellhead housing, the inner wellhead assembly having a lock ring with a lock ring profile that engages the locking profile. The engaging surface is a sloped downward facing surface at an axially upper end of the gallery slot. The annular notch has a notch engaging profile with a downward facing notch upper shoulder and an upward facing notch lower shoulder. The locking profile includes an inlay, the inlay being located on the notch upper shoulder and the engaging surface.

  • Patent number: 9732582
    Abstract: A wellbore system includes a sealing assembly for creating an annular seal between wellbore members. The sealing assembly includes a wicker profile defined a first sealing surface for engaging and embedding into a radially adjacent, second sealing surface. The wicker profile includes a first section having a first hardness and a second section adjacent to the first section and having a second hardness greater than the first hardness. Both the first and second sections of wickers are embedded into the second sealing surface, and can thus provide a high degree of both sealing and lockdown performance.

  • Patent number: 9695662
    Abstract: A retention system for limiting axial and radial movement of a wellbore lock ring. The retention system includes pins for resisting axial movement of the lock ring and assemblies for limiting radial outward movement of the lock ring. The lock ring circumscribes and couples to a wellbore hanger. The pins project radially from the hanger into the lock ring and into slots, where the slots extend a distance along the inner surface of the lock ring. The assemblies also project radially into the hanger and each have a portion that registers with a channel on a lower end of the lock ring. Lock ring outer radial movement is limited by contact between the portions of the assemblies and inner surfaces of the channels.

  • Publication number: 20150114668
    Abstract: A wellhead assembly includes a tubular wellhead housing having a bore and an annular gallery slot. The annular gallery slot is defined by an enlarged inner diameter of the bore. A tubular hanger is selectively landed in the bore of the wellhead housing, defining an annular cavity between the bore and an outer diameter of the tubular hanger. The tubular hanger is supported by the wellhead housing with a hanger support located in the annular cavity. A flow-by passage is in fluid communication with the annular cavity at locations above and below the hanger support. The flow-by passage intersects with the gallery slot and intersects an outer radial surface of the tubular hanger.
