Patent ID: 7946361

Claim:
A bottom hole assembly (BHA) for use in drilling a wellbore, the BHA comprising: a BHA mud motor having a stator and a rotor; a drill bit mud motor having a stator and a rotor; a drill bit rotationally coupled to the bit rotor and having a tool face and a longitudinal axis inclined relative to a longitudinal axis of the BHA mud motor; and a clutch, comprising: an output jaw rotationally coupled to the bit stator and having an asymmetric jaw face; and a rotary jaw rotationally coupled to the BHA rotor, an orienting jaw having an asymmetric jaw face, wherein: the clutch is operable to: rotationally couple the bit stator to the BHA stator in a sliding mode at a first orientation of the tool face, rotationally couple the BHA rotor to the bit stator in a rotary mode, change the first orientation to a second orientation by a predetermined increment, orient the tool face at the second orientation in an orienting mode, and shift among the modes in response to at least one of: a change in flow rate of a fluid injected through the clutch and a change in weight exerted on the drill bit, the rotary jaw is engaged to the output jaw in the rotary mode, and the asymmetric jaw faces are engaged in the sliding mode.
