Measure concentration of several gases to ppb or ppm, and isotopes, from a vehicle

  • All data collected at one second intervals.
  • All gas data is tied to a GPS location during processing
  • Uses multi-gas analysers
Detect plumes via discrimination from natural concentrations
  • Natural source plumes can be identified at a deviation of only a few parts per billion; nearly 10x smaller than anyone else can identify with certainty
  • Smaller leaks can be identified, and from a much greater distance (km vs. m)
Attribute a leak or plume to specific sources
  • Use an “excess ratio fingerprint”, the team is able to distinguish whether the leak is from combustion, versus distribution line gases, versus natural wetland methane, for example, and map each separately or in layers
  • Use of secondary tracer gases such as ethane or isotopic CH4 to distinguish between biogenic and thermogenic sources
Detect leaks in real time
  • Provenance of the plume can be identified both while driving and to a greater resolution during post-processing
