Rib-steered motor technology extends CT drilling applications ///
A new directional coiled tubing (CT) drilling steering technology is now available that is based on the concept of closed-loop steerable drilling systems from rotary drilling applications. The new 3-in., rib-steered motor (RSM) design includes three hydraulically expandable, surface-controlled ribs that generate the required wellbore contact forces that are necessary for drilling complex 3D well profiles. The RSM platform also offers the capability to drill virtually straight tangents, which is impossible with the combination of bent motors and downhole orientation devices.
