Abstract:
A drilling tool includes a pilot bit coupled to an eccentric reamer that has a reaming side and a stabilizing side. A fluid passageway extends between the reamer and the pilot bit, and the tool includes at least one upwardly-directed nozzle in fluid communication with the fluid passageway and positioned on the stabilizing side of the reamer. The reamer may include a plurality of angularly spaced blades on the reaming side that radially extend a first distance, the reamer blades being disposed within a first arcuate segment defined by the two most distant reamer blades. One or more stabilizing blades extend a second distance that is less than the first distance, the stabilization blades being disposed within a second arcuate segment defined by the two most distant reamer blades and that has the angular measure equal to 360 degrees minus the first arcuate segment.

Claim (Index 16):
A drilling tool comprising:\n a pilot bit concentric to a central axis and coupled to an eccentric reamer, the reamer including a reaming side with reamer blades and a stabilizing side with at least one stabilizer blade; a neck portion between the pilot bit and the eccentric reamer, wherein the neck portion includes a frustoconical outer surface that tapers from a first diameter adjacent the pilot bit to a second diameter adjacent the reamer, wherein the second diameter is greater than the first diameter a fluid passageway extending through the eccentric reamer and the neck portion; at least one nozzle in the reamer configured to direct fluid that is conveyed to the nozzle from the fluid passageway away from the pilot bit and in a direction that forms an acute angle as measured with respect to the central axis.
