The oil and natural gas industry includes a wide range of operations and equipment, from wells to natural gas gathering lines and processing facilities, to storage tanks, and transmission and distribution pipelines. The industry is a significant source of emissions of methane, a potent greenhouse gas. In order to reduce methane emissions, operators must regularly monitor their entire network to detect methane leaks. A reliable gas identification and quantification imaging system represents an upgrade to the current gas detection technologies. Infrared hyperspectral imaging can visualize fugitive emissions and gas leaks under various environmental conditions and industrial contexts. Aerial gas detection and quantification is an efficient way to survey large assets for possible leaks. This work will present the emission detection and quantification capabilities of Telops airborne hyperspectral imaging methane emission detection system for methane fluxes of 1,8 to 1,082 kg per hour of methane (kgh(CH4)). The data presented in this paper comes from controlled releases of methane conducted over various sites over the last 3 years as well as several emissions from functionnal industrial sites. In addition, the collected data spans a wide range of atmospheric conditions and flight parameters. This paper will also include a discussion on how plume flow rate quantification accuracy depends on the wind measurement
