A wellhead alignment system includes a visual marker configured to be placed at a wellhead and a camera configured to capture an image that includes the visual marker. The wellhead alignment system also includes one or more processors configured to apply computer vision algorithms to identify the visual marker in the image and to calculate an offset between the wellhead and a drilling rig based on a position of the visual marker in the image.

Wellhead alignment systems and methods

A system includes a hanger having a tapered radially-outer surface and a hanger sealing assembly configured to move between an unsealed position and a sealed position in which the hanger sealing assembly seals an annular space between the hanger and a housing of a wellhead. The hanger sealing assembly includes an annular sleeve, a first and second annular seal each comprising a respective tapered radially-inner surface configured to contact the tapered radially-outer surface of the hanger, and an annular seal-engaging sleeve. The annular seal-engaging sleeve is coupled to the first and second annular seals, and movement of the annular sleeve along an axial axis is configured to exert an axial force on the first annular seal, thereby causing the first and second annular seals to move axially and radially outward along the tapered radially-outer surface of the hanger to seal the annular space.

Hanger sealing system

A ram assembly is provided. In one embodiment, the ram assembly includes a base ram having a tapered profile and a seal coupled to the base ram in a manner that allows the seal to slide relative to the base ram during operation of the ram assembly. In some instances in which the ram assembly is installed in a blowout preventer, the tapered profile of the base ram can facilitate compression of the seal in multiple directions. Additional systems, devices, and methods are also disclosed.
