...William S. Daniels; Meng Jia; Dorit M. Hammerling We propose a modular framework for methane emission detection, localization, and quantification on oil and gas production sites that uses concentration and wind data from point-in-space continuous monitoring systems. The framework leverages...

...Thomas E. Barchyn; Chris H. Hugenholtz; Tyler Gough; Coleman Vollrath; Mozhou Gao Low-cost fixed sensors are an emerging option to aid in the management and reduction of methane emissions at upstream oil and gas sites. They have been touted as a cost-effective continuous monitoring technology...

... Observation System Research Infrastructure, 2019 ). The ROmanian Methane Emissions from Oil & gas (ROMEO) project ( Röckmann, 2020 ) aims to provide experimental quantification of methane emissions from oil and gas extraction activities. In this framework, the present work reports methane isotopic data...

... tests at two locations, we analyze the ability of mobile technologies to detect, localize, and quantify methane emissions. We find that the technologies are generally effective at detecting leaks, with 6 of the 10 technologies correctly detecting over 90% of test scenarios (true positive plus true...
