Trillium Compact Exploration

• Summary

  The Trillium Compact Exploration has been designed for rapid and repeated deployments and is specifically tuned for frequencies of 1Hz to 10Hz. It features an ultra-low noise floor and 20s corner frequency. Areas of application include:

  • Low frequency passive seismic surveys designed to identify hydrocarbon reserves
  • Total field monitoring of induced and natural seismicity
  • Event magnitude and location mapping
  • Cap rock integrity monitoring

  
• Benefits
  • Ultra-low noise floor with 20 s corner frequency to derive low frequency datasets
  • Uniquely tuned for frequencies of 1 Hz to 10 Hz: ideal for seismic surveys
  • Ease of deployment
    • 10° of levelling freedom to maximize data returns
    • Several integrated mounting options for quick deployments on any terrain
    • Available exploration kit with solar panel, battery, digitizer, and robust sensor
    • Data recorded at each station to avoid wireline deployment
