Abstract
A mud containment apparatus has pneumatically energized seals for sealing against the outer surface of tubulars such as drill pipe. The mud containment apparatus can be quickly and efficiently positioned about a threaded connection existing between adjacent pipe sections. During separation of the threaded connection, the mud containment apparatus contains and saves drilling fluid, thereby preventing drilling fluid from uncontrolled splashing or spilling.
