Abstract: Methane, the main component of natural gas, is the second-largest contributor to climate change after carbon dioxide. Methane has a higher heat-trapping potential but a shorter lifetime than carbon dioxide, and therefore, rapid reduction of methane emissions can have quick and large climate change mitigation impacts. Reducing emissions from oil and gas production facilities, which account for approximately 14\% of total methane emissions, turns out to be a particularly promising avenue partially due to the rapid development of continuous emission monitoring technology. A statistical framework is presented for quick emission detection, localization and quantification using continuous methane concentration data measured by multiple monitoring sensors on oil and gas production facilities, and its performance is shown in a test set using controlled release data where the emission rates are known. Its effectiveness is also demonstrated under real-world conditions and ideas for future directions are discussed.
