DIRECTIONAL DRILLING Pilot™ Fleet of Automated Drilling Systems

EZ-Pilot® Rotary Steerable System Reliable, cost-effective rotary steering

Sperry Drilling services’ EZ-Pilot® system delivers cost-effective rotary steering services to the greater drilling market. Rotary steering is no longer the domain of high-cost operations, such as deepwater offshore drilling. With the EZ-Pilot system, land and shallow-water operators can take advantage of all the benefits of rotary steering at an affordable price.

EZ-Pilot System Operation The EZ-Pilot system is an instrumented, near-bit stabilizer with three main components, including a rotating mandrel, an eccentric inner sleeve, and a weighted, nonrotating outer housing. The tool works by controlling the orientation of the eccentric cam system, which offsets the mandrel and the bit in the desired direction. Rotation of the cam system to change toolface orientation is accomplished by controlling an ultrahigh-torque DC motor powered by lithium batteries. The position of the outer housing is constantly monitored, and the tool automatically corrects the eccentric cam system setting as required to maintain proper toolface orientation. The target toolface is set through simple rotary speed commands, or “on-the-fly” downlinking commands, sent from the surface when coupled with either Geo-Span® software/PWD or electromagnetic telemetry. Capabilities and Features • Suitable for drilling vertical, directional, and horizontal applications • Capable of kicking off from vertical • Simple and cost-effective, with fewer than 130 components • Flow rate, rotary speed, weight-on-bit, or lost circulation materials restrictions are consistent with MWD limitations • Easily reconfigurable for different hole sizes

The EZ-Pilot system provides accurate directional drilling control while allowing continuous rotation of the drillstring. The tool employs the natural forces of gravity combined with simple, infrequent geometric changes, forcing the bit off-center, thus changing the trajectory of the well.

This cutaway shows the main components of the tool with a 90° right deflection. The EZ-Pilot® system has fewer than 130 total components.

Benefits • Zero “sliding” time for more effective ROP • Helps reduce drillstring buckling in long horizontals, greatly extending reach • Continuous rotation helps improve hole cleaning and reduces risk of getting stuck • Low pressure-drop design helps reduce hydraulics requirements, critical on smaller rigs • Helps increase ability to drill with more aggressive bits • Smoother wellbore curvature helps reduce torque and drag • Helps lower operating and lost-in-hole costs
