Abstract: A drill control system includes an uphole control device and a downhole control device. The uphole control device is configured to transmit a reference trajectory to the downhole control device and receive information about an actual trajectory from the downhole control device. The downhole control device is configured to receive the reference trajectory from the uphole control device, measure the actual trajectory, correct deviations between the reference trajectory and the actual trajectory, and transmit information about the actual trajectory to the uphole control device.

Abstract: A technique facilitates control over the actuation of a device by utilizing a rotor and a corresponding stator system. The technique employs a rotor and a corresponding stator component in a progressive cavity type system. The rotor and corresponding stator component are mounted such that rotational and/or axial motion may be imparted to at least one of the rotor or stator components relative to the other component. The controlled rotation may be utilized in providing controlled motion of an actuated device via the power of fluid moving through the progressive cavity type system.

Abstract: A downhole drilling apparatus includes a drill bit, a steering tool, and an anti-oscillation sleeve deployed about a downhole end of the steering tool. The anti-oscillation sleeve is undergauge and is deployed axially between a first touch point at which the drill bit contacts the borehole wall and a second touch point at which the steering tool contacts the borehole wall.
