Abstract: A reaming tool including a channel body having a fluid channel disposed therethrough. The channel body includes a rotational coupling structure that allows the channel body to rotatably couple. The channel body includes a jacket, a dynamic sleeve, a static sleeve, and a static mandrel. The reaming tool includes a rotational discharge body fixedly coupled to the channel body and including a fluid conduit system. The fluid conduit system is shaped to impart rotational force on the rotational discharge body when fluid is forced therethrough. The rotational discharge body includes a post enclosed by stacked discharge plates. The fluid conduit system includes an array of curved conduits. The reaming tool includes a reamer housing fixedly coupled about the rotational discharge body.

Abstract: A reaming assembly having an inner mandrel including spiral lobes disposed on an outer surface thereof. The inner mandrel is hollow and is sized large enough to freely pass a standard drill bit therethrough. The reaming assembly includes an outer mandrel disposed around the inner mandrel and includes spiral lobes disposed on an inner surface of the outer mandrel. The outer mandrel has a number of spiral lobes equal to the number of spiral lobes of the inner mandrel plus one. The reaming assembly includes a spacing between the outer surface of the inner mandrel and the inner surface of the outer mandrel through which fluid is pumped to generate torque therebetween; wherein at least one of the inner and outer mandrel is free to rotate.

Abstract: A reaming system including an elongated tubular housing having a first end and a fluid inlet aperture. The elongated tubular housing includes a second end having a fluid outlet aperture. The reaming system includes a first bearing pack disposed circumferentially about the first end of the housing. The first bearing pack is only of sacrificial materials which may be drilled through. The reaming system includes an auger. The reaming system includes a reaming tool functionally coupled to the auger. The reaming tool may be a tool selected from the group consisting of: a float shoe, a reamer shoe, and a guide shoe. The reaming system includes a second bearing pack functionally coupled to a bottom end of the auger. The reaming system includes a connection sub functionally coupled to a bottom end of the auger that transfers rotational motion from the auger to an attached tool.
