Abstract
An orientation mandrel rotatable in an orientation body for providing rotational orientation and actuated by a hydraulic piston controlling the position of a helix. A thruster may be connected to the orientation mandrel and is adapted to hydraulically engage the well bore by plurality of elongate gripping bars. An annular thruster piston is hydraulically and longitudinally movable in the thruster body for extending the thruster mandrel outwardly from the thruster body. However, the orientating tool and thruster may be used separately.
