    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.

    Abstract: A wellhead assembly includes an outer wellhead member having a bore and an inner wellhead member located in the bore, defining an annular pocket between the outer and inner wellhead members. A sealing assembly is located within the annular pocket, the sealing assembly having an annular seal and an energizing ring. The energizing ring engages inner and outer legs of the annular seal to push the inner and outer legs into sealing engagement with the inner and outer wellhead members. A retainer nut is threadingly attached to the free end of the outer leg of the sealing assembly. Mating grooves are located on one of an inner diameter of the retainer nut and an outer diameter of the energizing ring and mating protrusions located on the other. The mating protrusions mate with the mating grooves to prevent relative axial movement between the energizing ring and the annular seal.

    Abstract: A subset wellhead component has a metal seal surface having voids. The voids are initially filled with an elastomeric substrate having hollow beads. When lowered into the subsea assembly, the beads have sufficient strength to resist collapsing under a hydrostatic pressure of liquid within the subsea wellhead assembly to prevent shrinking of a volume of the substrate. Exerting a setting force on the metal seal surface to form the sealing engagement causes the beads to collapse and reduce the volume of the substrate within the voids. The seal surface may be folds of a bellows-type nose ring of a seal assembly. The seal surface may alternately be wickers formed in the bore of the wellhead housing.

    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.

    CPC classification number: E21B33/03

    Abstract: A wellhead assembly includes an inner wellhead member with wickers extending outwardly therefrom and an outer wellhead member with wickers extending inwardly therefrom. A seal assembly having an inner leg and an outer leg is inserted between the wellhead members. An energizing ring forces the legs radially apart from each other. An inlay is located along at least one of an inner diameter of the inner leg and an outer diameter of the outer leg, positioned to sealingly engage the wickers. The inlay is located in a single groove configured so that no part of the seal member body contacts an exterior wall of the inner wellhead member or an interior wall of the outer wellhead member. The inlay has a smooth outer surface flush with the diameter and is made of a material softer than the inner wellhead member, the outer wellhead member, and the seal member body.

    Abstract: A wellhead assembly includes as outer tubular wellhead member and an inner tubular wellhead member with a seal pocket between them. A seal ring is located in the seal pocket An annular energizing ring urges the seal ring into sealing engagement with the outer tubular wellhead member and the inner tubular wellhead member. A recess is located on an outer diameter of the annular energizing ring or a radially inner diameter of the seal ring, and a ratcheted retainer is on the other. A ratchet clip with a clip profile is located within the recess. The recess and the ratchet slip extend leas than a full circumferential distance around the outer diameter of the annular energizing ring or the radially inner diameter of the seal ring. A retainer profile on the ratcheted retainer selectively engages with the clip profile of the ratchet clip.
