... Ethane Oil and gas Hot spot Atmospheric methane (CH 4 ) is a potent long-lived greenhouse gas (GHG). It is emitted by both anthropogenic and natural sources. CH 4 global sum of sources estimated using atmospheric observations as constraints was found to be 500 Tg CH 4 /yr to 600 Tg CH 4 /yr...

...Geoffrey S. Roest; Gunnar W. Schade; Detlev Helmig; Stefan Schwietzke The Eagle Ford Shale in southern Texas remains one of the most productive oil and gas regions in the US. Like the Permian Basin and Bakken Shale, ubiquitous natural gas flaring serves as an uncertain source of trace gas emissions...

... find that emissions from the oil and gas sector account for 20% of regional methane, with 95% confidence limits of (0%, 51%). The experimental uncertainties bound the inventory apportionment of 1.9%, though the central estimate of 20% exceeds this result by nearly 10 times. This study’s uncertainties...

... observed in rural areas where oil and gas activity is the primary source of O 3 precursors. On individual days, oil and gas O 3 precursors can contribute in excess of 30 ppb to O 3 growth and can lead to exceedances of the EPA O 3 National Ambient Air Quality Standard. Data used in this study were gathered...
