An orienter, particularly on coiled tubing or small diameter drill pipe, includes a motor, turbine, or other device for selectively converting the rotational kinetic energy produced from fluid flow through the device to mechanical power, and applying the mechanical power to a downhole tool through a gear train for orienting the downhole tool. The orienter is utilized during directional drilling and other operations such as well intervention, fishing, and multilateral re-entry operations. The downhole tool preferably includes a steerable mud motor. In one embodiment, the direction of the borehole is controlled by azimuthal rotation of the orienter of the present invention in response to downlink commands from the surface by changing fluid flow rate through the orienter in a predefined series of steps.
