Abstract: A system and method (1000; 1050) for a well structure adaption (402) to be used with a wellhead casing for a reusable system (942; 962A; 962B), such as a system for renewable energy generation is disclosed. A well structure adaption includes an annular feature (404; 506) and a housing (412; 504). The annular feature includes a narrowing (406) therein and is able to fit over the wellhead casing (110; 202). The housing is associated with a segmented clamp (508) and a drive screw (502). The housing is to fit over a portion of the annular feature. The drive screw is to enable the housing to be releasably clamped to the annular feature with the segmented clamp. The housing can support at least one aspect of a reusable system thereon.

Abstract: A system for blocking rotation between a first tubular and a second tubular includes a key positioned within a recess formed in the first tubular. The system also includes a retention fastener securing the key to the first tubular, the retention fastener being arranged within an elongated aperture extending through the key. The system further includes an installation fastener moving the key from a storage configuration when in a first position to an engaged configuration when in a second position, the installation fastener having a tapered face that engages at least a portion of the key. The system also includes teeth arranged along a bottom portion of the key, proximate the second tubular, the teeth engaging the second tubular via rotation of the key about the retention fastener and blocking rotation of the first tubular relative to the second tubular in a first direction.

Abstract: An annulus seal for sealing an interface between a wellhead housing and a casing hanger. The annulus seal includes a central body portion, a first seal leg extending from the central body portion in a first direction and a second seal leg extending from the central body portion in the first direction across from the first seal leg. The first seal leg sealingly engages the casing hanger, and the second seal leg sealingly engages the wellhead housing. At least one of the first seal leg or the second seal leg includes at least one of a first cavity at least partially extending into the respective seal leg from the first direction or a second cavity at least partially extending into the respective seal leg from the second direction.
