Claim 11:
12. The method of claim 11, where conditioning the wellbore with the hydraulically driven rotating string reamer assembly comprises:
circulating the drilling fluids through the drill string, where circulating the drilling fluids through the drill string produces a flow of drilling fluid that causes the hydraulic drive to rotate the rotating string reamer relative to the drill string, drill bit, and near-bit reamer;
while circulating the drilling fluids through the drill string, translating the drill string axially in the wellbore in an uphole direction, where:
translating the drill string in the uphole direction translates the hydraulically driven rotating string reamer assembly axially along at least a portion of the new interval of the wellbore; and
rotation of the hydraulically driven rotating string reamer assembly relative to the drill string removes at least a portion of imperfections protruding radially inward from the wellbore wall in the new interval.
