Abstract
An apparatus and a method to control rotational positioning of continuous concentric tubing that extends from a surface downhole in a subterranean well or bore. In one version, a continuous cylindrical inner tube resides within and is concentric with a cylindrical outer tube. At least one elliptical lobe extends from the continuous inner tube. The invention utilizes diameter restrictions within and attached to the outer concentric tubing so that the elliptical lobe or lobes engage the diameter restrictions. Accordingly, rotation of one tube rotates or orients the other tube.
