... was carried out in January and October 2020. Molar ethane to methane ratios (EMRs) were quantified, which may be used to distinguish emissions from particular sources, such as produced gas and oil tank flashing. The geometric mean EMR for 100 observations was 18 (±2)%, while source specific EMRs showed...

... sources, experienced elevated surface air pollution under low wind and surface temperature inversion at night and early morning. Survey drives in the basin identified multiple CH 4 and ethane (C 2 H 6 ) sources with distinct C 2 H 6 -to-CH 4 emission plume ratios for coal bed methane (CBM), natural gas...

... ) are lower than inventory predictions (14 Mg hr –1 ) but the proportion of fossil fuel sources is higher than indicated by the inventory. Apportionment of methane emissions between thermogenic and biogenic source types used ethane/methane ratios in aircraft flasks and ground-based source characterization. We...
