French energy giant TotalEnergies is launching a drone-based methane emissions detection program across all its upstream oil and gas operated sites. The global campaign will use a greenhouse gas measuring technology called Airborne Ultralight Spectrometer for Environmental Applications (AUSEA) that TotalEnergies has developed in collaboration with the French National Research Center for Scientific Research (CNRS) and the University of Reims Champagne Ardenne.

AUSEA leverages a drone-mounted miniature dual sensor, capable of both detecting methane and carbon dioxide emissions and identifying their source. Measurements can be taken at all types of industrial facilities – whether onshore or offshore.

The company says drone inspections will supplement measurements taken using traditional techniques such as infrared cameras, ground sensors, and satellite data.
