Abstract: A technique facilitates drilling of a variety of a wellbores. The technique comprises providing a directional drilling system with a drill bit mounted at the end of a collar having an internal flow passage for drilling fluid. The collar is rotatably positioned in a steering structure to which a plurality of steering members is mounted for lateral motion with respect to the steering structure. The design allows the steering structure to remain rotationally stationary with respect to the surrounding borehole wall as the collar and drill bit are rotated to perform a drilling operation. The drilling orientation of the collar and the drill bit may be adjusted by routing drilling fluid from the internal flow passage to at least one of the steering members to cause lateral displacement of the steering member while the steering structure remains in the rotationally stationary position.

Abstract: A technique facilitates control over the actuation of a device by utilizing a rotor and a corresponding stator system. The rotor is rotatably mounted in the stator system, and rotation of the rotor relative to the stator system is correlated with the volumetric displacement of the fluid passing between the rotor and the stator system. A control system is employed to control the angular displacement and/or torque of the rotor and/or the flow of fluid thereto.

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.
