  • Robust design for drilling with RSS at high RPMs
  • Cost-effective EM & MP modular telemetry combination
  • Turbine alternators of proprietary design
  • Configurable real-time data and memory mode settings
  • Communication with logging tools and RSS, power supply for the entire BHA
  • Downlinks via mud flow modulation

Applications

  • High ROP drilling in EM-friendly formations
  • Managed pressure drilling (MPD) and underbalanced drilling (UBD
  • Pumping high volumes of LCMs

Benefits

  • Lowest operating costs
  • Very high data rate – up to 10 bps
  • Hybrid turbine + battery power source for underbalanced drilling
