Designed to overcome North American land challenges, Scientific Drilling’s HALO high-performance rotary steerable system solves reliability and economic difficulties while yielding more efficient, smoother wellbores.

Built to complete vertical, curve, and lateral sections in one run, it helps avoid costly trips and improves ROP. Operating at a maximum bit speed of up to 350 RPM, the HALO RSS maximizes performance and reduces rig time.


  • Performance drilling
  • Extended-reach wells


  • High RPM limit Improves drilling performance
  • Build rate capability (up to 15°/100 ft) maximizes reservoir exposure in the target zone
  • Enhances drilling efficiency due to superior automated lateral/3D advanced directional control functionality
  • Reduces handling risk and invisible time through an integrated system design


  • Magnetic referenced kickoff from vertical
  • Compatible with Scientific Drilling’s TITAN 22 highperformance mud motors, as well as third-party motors
  • Real-time azimuthal gamma ray measurements and near-bit navigation package provides continuous feedback
  • Real-time continuous equivalent circulating density (ECD) measurements enable continuous hole cleaning monitoring
  • Downlink commands can be transmitted during drilling, while pulsing MWD data to surface
  • Real-time vibration readings: lateral, axial and stick-slip
