Patent number: 10968716Abstract: A wellhead includes a wellhead body and a locking end coupled to the wellhead body. The locking end includes an exterior surface with an exterior locking profile. The exterior locking profile includes an exterior groove formed between exterior stab and load flanks on the exterior surface. The locking end also includes an interior surface having an interior locking profile. The interior locking profile includes an interior groove formed between interior stab and load flanks on the interior surface. At least one of the exterior groove or the interior groove is a relief groove that undercuts at least one of the respective stab or load flank. The relief groove corresponds to a portion of the contour of an ellipse intersecting at least a portion of the respective stab or load flank, and an axis of the ellipse is at a tilted angle with respect to an axis of the wellhead.Type: GrantFiled: January 24, 2019Date of Patent: April 6, 2021Assignee: Vetco Gray, LLCInventors: Baozhi Zhu, Joseph Pallini

Patent number: 10947804Abstract: A system is disclosed as including a seal for sealing an area between a hanger and a housing of a wellhead. The seal is provided with at least a notch that defines at least a movable portion such as a wing or a lip. An e-ring is provided for a first energizing of the seal. The movable portion enables pressurized fluid from beneath the seal to cause the movable portion to protrude further against a mating side in the wellhead and the hanger for a second energizing of the seal. This type of seal maintains or improves the sealing of the wellhead in high pressure applications. Methods applied to the above seal are also disclosed.Type: GrantFiled: April 5, 2019Date of Patent: March 16, 2021Assignee: Vetco Gray, LLCInventors: Andrew Ingram, Greg Dunn, Alejandro Martinez, Ronnie Hampton, Joseph Pallini
