Abstract: A system for installing a corrosion cap on a mudline suspension system may include a method of inserting the corrosion cap into a running tool. One or more drive pins of the corrosion cap may be slotted into one or more J-slots of the running tool. The one or more drive pins may be positioned in a circular section of the one or more J-slots. One or more shear screws may be set in holes of the running tool corresponding to a vertical section or a horizontal section of the one or more J-slots. The corrosion cap may be removably locked to the running tool. The corrosion cap is landed on the mudline suspension system of a well. The one or more shear screws may be sheared to disengage the corrosion cap from the running tool. The running tool may be retrieved to a surface above the well.

Abstract: A wellbore surface assembly includes a slip assembly, vertical rails, linear actuators, and an iron roughneck. The slip assembly is attached to a floor surface of a wellbore and it includes movable slips that engage a first tube. The vertical rails are attached to the base of the automatic slip assembly. The iron roughneck is movable along the vertical rails. The automatic iron roughneck includes a frame, a rotary ring, die actuators, and dies. The iron roughneck is movable by the linear actuators along a length of the vertical rails, changing an elevation of the iron roughneck with respect to the automatic slip assembly and the floor surface of the wellbore. The dies engage the second tube and the rotary ring rotates the second tube, threadedly attaching or detaching the second tube from the first tube.

Abstract: Methods and systems for maintaining a drill bit includes positioning a cutter within a recess of a drill bit body so that an initial edge is positioned at a first location that is a radially outward location relative to a blade of the drill bit. A threaded member extended through a central bore of the cutter can be rotated to releasably secure the cutter to the drill bit. The subterranean well is drilled with the drill bit. The threaded member can be rotated in a second direction so that the cutter can be rotated relative to the recess and the initial edge of the cutter is positioned at a second location that is rotationally offset from the first location. The threaded member can be rotated to releasably re-securing the cutter to the drill bit and the subterranean well can continue to be drilled with the drill bit.
