    Abstract: Some embodiments of the disclosure relate to an apparatus that may reduce friction of a tubular structure in horizontal or deviated well. An apparatus is provided for mounting on a tubular structure, such as a casing or drill string having a longitudinal axis. The apparatus comprises a tubular segment for mounting over the casing or drill string such that the apparatus is freely rotatable about the longitudinal axis. The apparatus also includes a plurality of ridges on the outer face of the tubular segment, the ridges being at an angle to an axial direction of the tubular segment to cause the apparatus to rotate responsive to movement of the apparatus against a wall of the wellbore as the apparatus traverses the wellbore. The raised ridges have a non-uniform height from the outer face of the tubular segment.

    Abstract: An off-axis “cam” drilling tool is provided. The off-axis “cam” drilling tool includes an outer tubing having a throughbore therein, an inner tubing having a throughbore therein, the inner tubing being configured to be inserted within the throughbore of the outer tubing. An annulus is defined between the inner tubing and the throughbore of the outer tubing through which a medium may pass. A cam section can be configured on a portion of the exterior surface of the outer tubing. The outer tubing can be coupled to drill rods of a drill string. The cam section has an axis that is offset to an axis of the outer tubing, and the tool is configured to rotate about cam section axis to lift the drill rods coupled to the outer tubing above a centerline of a drill bore to beneficially orient the drill bit drilling the drill bore.
