Technical Data S ummary 4¾-in. AutoTrak G3 RCLS Building on the success of the most technologically advanced Rotary Closed Loop System (RCLS), the AutoTrak™ G3 RCLS encompasses the latest levels of MWD / LWD development in a rugged modular design. This third generation system opens new opportunities in all aspects of directional drilling, including both geosteering and extended reach applications. The tool can automatically steer itself during continuous rotation of the drill string with changes to the well trajectory communicated to the tool from surface while drilling ahead. Truly integrated Drilling and Evaluation BHA design concept, which enable placement of LWD and other sensors close to the drill bit, making the system ideal for geosteering applications. The advanced inclination HOLD mode brings extreme precision when drilling long tangents, even at low inclinations. Near to Bit Directional, Rotational Azimuthal Gamma Ray, Multiple Propagation Resistivity, real time pressure and vibration measurements are included in the AutoTrak G3 RCLS System. The AutoTrak™ G3 RCLS is always engaged, not on/off duty cycles, but a constant, continuous and consistent control with more than 7,000 different steering vectors available. This advanced drilling system continuously adjust the force to meet the target with the smoothest possible wellpath, even under the most challenging condition, delivering a superior hole quality. The AutoTrak™ G3 RCLS system steers with pressurized pads using hydraulic pumps. No minimum pressure differential limitations, optimize bit hydraulics to improve drilling performance. Features Benefits Continuous drill string rotation from surface and adjustment of steering targets while drilling ahead. Maximum drilling performance with minimum risk and non-productive time. Precise closed loop steering with continuous, smooth adjustment of steer direction and advanced inclination hold mode. Straight, in-gauge tangents and precise curves with excellent hole quality for troublefree completions and improved ROP. Steering pads decoupled from fast rotation in short, slowly rotating sleeve. Consistent steering in all environments, including soft formations and overgauged hole. Full capability of open-hole sidetracks. Steering independent of bit pressure regime. Optimized bit performance and ECD management. Pads fully retract into tool body on command or power-down, allowing full rotation of all parts. Minimized sticking risk and no restrictions in reaming and tripping operations. 4¾-in. AutoTrak G3 RCLS ©2013-2014 Baker Hughes Incorporated. All rights reserved. ATK3.0-70-01-002 Rev.
