ABSTRACT
Since 1979, Eastman Christensen-the world's leader in horizontal drilling services-has provided its proven Lateral Drilling Systems to the industry. The short-radius rotary system has been used to drill over 350 horizontal well bores, more than any other comparable system. Eastman Christensen's new short-radius motor system employs advanced downhole motor technology to build well bore inclination to horizontal along a radius of only 40 ft/13 m. Powered by a short, articulated Positive Displacement mud Motor, the short-radius system puts more power at the bit for better ROP than rotary techniques. The short-radius motor system uses a custom, flexible Directional Orientation Tool to determine real-time tool face orientation and hole direction during drilling. The short-radius lateral drilling system uses a variety of Eastman Christensen's survey technology to orient, monitor and map the lateral well bore.
