...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...

...Mark Argento; Fiona Henderson; Rachel Lewis; Deirdre A. Mallyon; David Risk; Nicholas Nickerson As oil and gas wells age and the number of wells drilled increases to meet demand, we may see more instances of fugitive soil gas migration (GM) and associated methane (CH 4 ) emissions. Due...

It is emitted by both anthropogenic and natural sources. CH 4 global sum of sources estimated using atmospheric observations as constraints...

...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...

...Seth N. Lyman; Trang Tran; Marc L. Mansfield; Arvind P. Ravikumar; Detlev Helmig; Brian Lamb We deployed a helicopter with an infrared optical gas imaging camera to detect hydrocarbon emissions from 3,428 oil and gas facilities (including 3,225 producing oil and gas well pads) in Utah’s Uinta Basin...

Results from this study further support emerging evidence that methane detection technologies for oil and gas applications should be evaluated on a different framework than a simple...

... 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...
