Abstract:
What is provided is a method and apparatus which can be detachably connected to an annular blowout preventer thereby separating the drilling fluid or mud into upper and lower sections and allowing the fluid to be displaced in two stages, such as while the drill string is being rotated and/or reciprocated. In one embodiment the sleeve can be rotatably and sealably connected to a mandrel. The swivel can be incorporated into a drill or well string and enabling string sections both above and below the sleeve to be rotated in relation to the sleeve. In one embodiment the drill or well string does not move in a longitudinal direction relative to the swivel. In one embodiment, the drill or well string does move longitudinally relative to the sleeve of the swivel.

Claim (Index 19):
A method of performing operations in a wellbore, the method comprising the following steps:\n (a) attaching a swivel to a drill string, the swivel including a mandrel having a longitudinal axis and a sleeve, the sleeve being rotatably connected to the mandrel with the sleeve including at least one catch that restricts the extent of longitudinal movement of the sleeve relative to a blow-out preventer, the blowout preventer being fluidly connected to a wellbore and a riser; (b) detachably connecting the blowout preventer to the sleeve by closing a seal of the blowout preventer which detachable connection fluidly separating the riser from the wellbore; (c) during a time period while the blowout preventer is detachably connected to the sleeve and where high differential pressure exists above and below the seal of the blow-out preventer, and which high differential force attempts to push the sleeve vertically out of the closed seal, performing operations in the wellbore, wherein the at least one catch in combination with the closed seal prevents the sleeve from being pushed vertically out of the closed seal.
