Abstract
What is provided is a method and apparatus wherein a rotating and reciprocating swivel of adjustable stroke length and shearable by ram blow out preventers can be detachably connected to an annular blowout preventer thereby separating the lower wellbore from the riser. In one embodiment the mandrel of the swivel extends through a sleeve/housing. The sleeve/housing has a wiping arrangement of improved configuration that wipes debris from the mandrel, preventing entry of the debris into the sleeve/housing. Ports enable discharge of the removed debris from the area of the sleeve/housing.
