  5. Slide 5: Methane

    Methane Natural Gas • Powerful greenhouse gas with a warming impact 86 times stronger than CO2 per unit of mass over a 20-year period • Atmospheric lifespan of around 12 years. • Reducing methane emissions can slow the rate of warming and have positive impacts in our lifetime. © EXOSENS restricted &

  6. Slide 6: Measurement Techniques

    Measurement Techniques • Optical gas imagers (OGIs) • Strong gas detection capabilities. • Limited in their ability to accurately identify type of gas. • Not suited to survey multiple assets rapidly and cost effectively. • Approved method for detecting fugitive methane emissions from equipment. • Ae

  19. Slide 19: Detection Limit

    Detection Limit Predicted and Calculated The system sensitivity (expressed as the methane detection limit) depends on various variables: Flight parameters (speed & AGL) Instrument settings (image width) Environmental conditions (Thermal contrast, Wind speed and RH) Pre-flight: Telops developed a too

  20. Slide 20: AMEP Test Campaign

    AMEP Test Campaign Release Locations, Test Parameters and Conditions Methane release rates varied from 0.07 to 22.2 g/s (0,2 to 80 kg/h) including also “No Release” conditions Wind speeds varied from 1.7 to 4.1 m/s (6.1 to 14.8 km/h) Flight speed varied from 46 to 90 knots Telops recommends 70 knots
