Performance drilling with enhanced trajectory control

The PowerDrive Orbit RSS is highly versatile, tough, and reliable in any global operational environment. It cuts drilling time and increases efficiency with its ability to steer at high surface rpm. An innovative pad design features metal-to-metal sealing to handle aggressive drilling fluids and severe downhole conditions. With dual downlink options, including the QuikDownlink continuous-circulation downlink service, it fulfills all commands from surface in any rig type, enables real-time decision making, and provides excellent trajectory control.

Real-time data for accurate well positioning

Supporting up to 350 rpm, the PowerDrive Orbit RSS delivers higher ROP and helps to minimize stick/slip. It provides six-axis continuous survey and azimuth measurements that, together with automated downhole closed loops that include hold inclination and azimuth mode, optimize outcomes for well placement, trajectory control, and smoother boreholes. PowerDrive Orbit RSS minimizes dogleg severity in laterals, enables early control, and drives consistency in drilling operations. Early identification of zones of interest are provided by its extended gamma ray measurement.

Toughness and versatility to take on any environment

The PowerDrive Orbit RSS has enhanced durability for severe downhole conditions. It can drill from shoe to TD in a single run, reducing operating days. It provides extra reliability in complex operations where stick/slip, severe shock and torque, and complex hydraulic systems are significant risks.
