The Powerdrive Orbit tool is Pacesetter’s Rotary Steerable System. It is a robust tool with improved control in harsh environments. It allows for higher mud weights, larger flow ranges, aggressive mud and improves debris removal. The Powerdrive Orbit gives more control during stick/slip situations, better control during jamming and it improves overall reliability. Using a Rotary Steerable System reduces drilling time by minimizing wiper trips and increasing hole quality, allowing for improved and faster completions.


  • Closed loop directional control.
  • Capability to engage/disengage via downlink.
  • Automatically adjusts steering percentage.
  • Nudges can increase/decrease inclination by 0.5 deg.
  • Can be combined with azimuthal bias
  • Up to 50% left and right
  • +/‐ 12.5% increments


  • Steering setting is downlinked from surface.
  • The entire string rotates while steering in the desired direction.
  • Full 3D steering capability to gravity or magnetic orientation.
  • Both Inclination and Azimuth can be controlled while drilling via downlink.


Powerdrive has two main assemblies:

  • Bias Unit (BU): Converts hydraulic pressure drop across the bit nozzles and flow restrictor (if used) into mechanical energy for steering the well path.
  • Control Unit (CU): Provides directional platform from with the Bias Unit is controlled allowing the tool to steer in desired direction. Linked with the Bias Unit through a mechanical coupling.
