Abstract: A snubbing plug containing a body and a piston is configured to be secured within a component of a mineral extraction system by an internal locking mechanism. A fluid passage extends at least partially through the piston of the snubbing plug. The snubbing plug is configured to selectively open the fluid passage during installation or removal of the snubbing plug.

Abstract: A system, including a plug, including one or more fluid pathways extending between upstream and downstream sides of the plug, and an internal lock positionable in an unlocked position and a locked position, wherein the internal lock is resiliently biased to the locked position upon release from the unlocked position, wherein the locked position is configured to internally secure the plug within a wellhead component.

Abstract: A snubbing plug is configured to be secured within a component of a mineral extraction system by an internal locking mechanism. In addition, the snubbing plug enables pressure equalization of regions above and below the plug before removal of the plug. Upon insertion of the snubbing plug into a well component, pressure may be equalized via fluid pathways through the snubbing plug. The pathways are sealed closed during snubbing operations and opened again when snubbing operations are complete. Manipulation of the fluid pathways may be accomplished via rotation of a load ring within the snubbing plug.
