Abstract: In at least one embodiment, a valve removal (VR) system for an oilfield equipment includes a VR plug having a first surface and a second surface. The VR system includes a bushing to be removably associated with the first surface. The bushing is to extend, at least partly, beyond the second surface of the VR plug. The bushing is also to contact an inner surface of a valve of the oilfield equipment and to prevent the second surface from contacting the inner surface of the valve. The VR system includes a guiding rod to be associated with the VR plug to support guidance of the VR plug through the valve of the oilfield equipment. The guiding rod is also to be disassociated from the VR plug to support removal of the guiding rod from the valve with the VR plug remaining in the oilfield equipment.

Abstract: A wellbore system includes an upper head and a lower head coupled to the upper head by one or more fasteners. The wellbore system also includes a seal ring positioned within a seal pocket to engage the upper head to form a first seal interface between the upper head and the seal ring. The wellbore system includes a hanger arranged within a bore. The wellbore system includes a packoff positioned between the hanger and the lower head. The wellbore system includes one or more lock screws to apply a downward force to the packoff to establish a second seal interface between the packoff and the seal ring and a third seal interface between the packoff and the hanger.
