Methane leak

Following early reports that the escape might exceed 105 tonnes, The International Methane Emissions Observatory of the United Nations Environment Programme analysed the release.

[3][4] Satellite data detection has shown that methane super emitter sites in Turkmenistan, USA and Russia are responsible for the biggest number of events from fossil fuel facilities.

[5] Quantitative reports of methane leaks often use the standard cubic foot (scf) of the United States customary system.

Applied to natural gas, a complex mixture of uncertain proportions, and depending on pressure and temperature conditions, the accuracy of calculations converting scf to metric units of mass is subject to limitations.

[12] The methane leak from the Permian Basin, a significant region of the Mid-Continent Oil Producing Area, was estimated for 2018/9 from satellite data as 2.7 Tg/yr.

[13] The 2021 Carbon Mapper project, a collaboration of the Jet Propulsion Laboratory and academia, detected 533 methane super-emitters in the Permian Basin.
