Abstract: A rotary steerable drilling system includes a housing, a drive shaft passing through the housing, a shaft/housing locking mechanism disposed to selectively engage the drive shaft and the housing, and an anti-rotation mechanism disposed to engage a wellbore wall. Shaft/housing locking mechanism includes a first configuration in which rotation of the drive shaft is independent of the housing, and a second configuration in which rotation of the drive shaft causes rotation of the housing. Anti-rotation mechanism includes a first configuration in which the anti-rotation mechanism extends radially relative to the drive shaft, and a second configuration in which the anti-rotation mechanism retracts from engagement with the wellbore wall. A timing mechanism may be employed to transition the anti-rotation mechanism from the first configuration to the second configuration before the shaft/housing locking mechanism transitions from the first configuration to the second configuration.

Abstract: A bearing assembly for a downhole drilling motor can include a housing having an inner wall, an outer bearing race within the housing, and an inner bearing race. The outer bearing race can include a reduced-diameter portion forming a gap between the outer bearing race and the inner wall of the housing to allow for radial displacement of the outer bearing race relative to the housing. The design combines the functions of a bearing and a compliant feature into a single unit. The design will also provide reliability of performance in high dogleg and short bit-to-bend applications where radial loads are extreme and bearings frequently fail.

Abstract: A clamping assembly may include a split-ring device and bearing for coupling to a driveshaft. The split-ring device may comprise split-ring shells having protrusions on an interior radial surface for positioning in grooves adjacent to radial protrusions on the driveshaft. In some aspects, the split-ring shells may include tabs corresponding to cavities on a first bearing for coupling the split-ring shell to the first bearing. In other aspects, the split-ring shells may be sized to create one or more gaps when positioned on the driveshaft. The first bearing may include one or more corresponding tabs for positioning in the one or more gaps created by the split-ring shells. A second bearing may be threadably coupled to the first bearing to suppress the axial and rotational movement of the clamping assembly separate from the driveshaft.

Abstract: A drilling assembly includes a straight housing in which a mud motor assembly is mounted. The mud motor includes a rotor that rotates within a stator. The rotor has an axial centerline substantially parallel with the housing. A drivetrain is coupled between the rotor and a driveshaft. The driveshaft is coupled to a drill head. The driveshaft has a centerline that is non-coincident with (i.e., offset or angled) the axial centerline. The angle between the driveshaft centerline and the axial centerline may be fixed or variable. The angle may be variable in response to an axial force, imparted to the rotor, that is transferred to the driveshaft through the drivetrain. Additional apparatus, systems, and methods are disclosed.
