...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...

... composition data for the SJB are available from the Global Inventory of Gas Geochemistry Database ( Sherwood et al., 2017 ), which includes data from Rice (1993) , the U.S. Geological Survey Geochemistry database ( USGS, 2014 ), and the Colorado Oil and Gas Conservation Commission, among many others...

...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...

... chosen because their ambient background concentrations are relatively constant; fast, high-precision instruments to measure them are available; and they are not expected to be present at oil and gas sites (with rare exceptions, see SM Text S1, Section 3). Since downwind concentration enhancements...

... 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...

...Chelsea R. Thompson; Jacques Hueber; Detlev Helmig; Michael E. Chang The Northern Front Range (NFR) region of Colorado has experienced rapid expansion of oil and gas extraction from shale and tight sands reservoirs in recent years due to advances in hydraulic fracturing technology, with over 25,000...
