Scientific Drilling’s High Build Rate Rotary Steering System is designed with dedicated properties to address pre-dominantly land based appl icat ions in highly cost-sensit ive environments. This innovative system provides accurate and eff icient RSS drilling services in vertical, high build and long lateral well profiles, based on SDI’s existing MWD System which has been ranked highly in the industry for it’s accuracy and robustness. The system is delivered fully assembled to the well site.

Compatible with high-performance mud motors with maximum bit speed up to 350 rpm

Capable of drilling curve section with build rate up to 15°/100 ft, maximizing wellbore exposure in target zone

Allows precise on-the-fly directional control without interrupting the drilling process

Real-time azimuthal gamma ray measurements and near-bit inclination deliver optimal wellbore placement and prevent unintended bed boundary exit

Early detection and prevention of drilling problems via continuous Equivalent Circulating Density (ECD) monitoring

Downlink commands can be transmitted while drilling, pulsing MWD data to surface, and without requiring additional rig equipment

Precise wellbore placement and exceptional hole quality
