10. A method of preparing a rotating and reciprocating swivel tool while located on a drilling rig or platform, comprising the steps of:
(a) providing a swivel tool, the swivel tool comprising a mandrel and a sleeve surrounding the mandrel, the sleeve having an exterior sealing surface, said sleeve having an inner volume and upper and lower end portions, an interior volume between the mandrel and sleeve which is sealed by a pair of spaced apart sealing units, each end portion having a wiper cavity with a wiper, the mandrel being rotatable and reciprocable relative to the sleeve, the mandrel extending into the inner volume and having a first stroke length relative to the sleeve;
(b) lowering the swivel tool in a riser and towards a blowout preventer and wellbore, and supporting an upright orientation swivel tool;
(c) repeating step “b” until the final stroking length of the mandrel relative to the sleeve is at least 150 feet; and
(d) detachably connecting the exterior sealing surface of the sleeve to a seal of the blowout preventer, wherein the seal of the blowout preventer can be selectively closed on the exterior sealing surface of the sleeve, and while the seal is closed and forms a seal against the exterior sealing surface of the sleeve and separates upper and lower volumetric sections of fluid, the upper volumetric section being located in the riser above the blowout preventer and the lower volumetric section being located in the wellbore below the blowout preventer, wiping the mandrel with one or both of the wipers to prevent debris from damaging the upper and/or lower sealing units.
