The PowerDrive vorteX RSS enables drilling with increased ROP, maximizes power at the bit to drill longer runs, and increases the rig’s operating envelope. Its rotation conditions the hole while drilling and is proven to reduce risk of sticking, casing wear, and drillstring fatigue.

Power section for maximized drilling efficiency

The system’s fully integrated power section converts mud hydraulic power to mechanical energy, maximizing the power to drill hard formations. 

Multiple stabilization options for high-performance directional drilling

The PowerDrive vorteX RSS is compatible with an autosteering feature and hold function to enable drilling tangent or horizontal sections automatically, delivering higher accuracy and ROP. This enables drilling a hold section at a higher ROP and with greater accuracy compared with a conventional setup operated from the surface.

Improve directional performance & drilling efficiency

Delivering high ROP in hard-rock drilling applications, the RSS bearing package and transmission section are specifically designed for high operating loads, ensuring reliable, consistent performance during runs. The PowerDrive vorteX system has an inclination hold function that allows a tangent or horizontal section to be drilled automatically without intervention from the directional driller.
