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 32):
A swivel insertable into a drill or work string comprising:\n (a) a mandrel having upper and lower end sections and connected to and rotatable with upper and lower drill or work string sections, the mandrel including a longitudinal passage forming a continuation of a passage in the drill or work string sections; (b) a sleeve having a longitudinal sleeve passage, the sleeve being rotatably connected to the mandrel; (c) a packing unit between upper and lower end portions of the mandrel and sleeve, the packing unit preventing leakage of fluid between the mandrel and sleeve, the packing unit comprising a rope seal in combination with at least one non-rope seal, wherein the non-rope seal comprises teflon.
