Reservoir Monitoring


SADAR-E Real-time Subsurface Activity Detection


SADAR®-E is an event-driven, seismic-acoustic monitoring technology solution that classifies and locates subsurface events of interest, automatically and in real-time.


Leveraging compact, phased array processing, SADAR delivers greater range and accuracy via a reduced seismic data acquisition network. By including spatial processing into the analytic sequence, SADAR is able to detect, associate, locate, and identify events of interest in the presence of elevated noise and clutter.


  • Persistent -Always on, always listening, always processing
  • Real-time
    • Timely information is actionable information resulting in informed decision making
  • Highly Sensitive
    • Greater Range
  • Compact, phased arrays
    • Spatial analytics enhance results and disassociate unwanted noise and clutter
    • Improved locations with reduced uncertainty
  • Reduced Surface Footprint
    • Environmental and land owner upside
    • Lower risk to lifecycle and maintenance costs
  • User Interface Interactive Map Displays
    • Array(s) location
    • State-of-health status of individual SADAR arrays
    • Detection, classification, and localization alerts
