Four corners: The largest US methane anomaly viewed from space

Geophysical Research Letters
16 Oct 2014
Eric A. Kort, Christian Frankenberg, Keeley R. Costigan, Rodica Lindenmaier, Manvendra K. Dubey, Debra Wunch
Satellite data, as well as earth-based remote sensing, is used to compare federal emission estimates to real-world observations and finds that the largest methane anomaly viewable from space is located over the Four-Corners regions of the southwestern U.S., the source of which is likely fossil fuel development.

Limited impact on decadal-scale climate change from increased use of natural gas

Nature
15 Oct 2014
McJeon H, Edmonds J, Bauer N, Clarke L, Fisher B, Flannery BP, Hilaire J, Krey V, Marangoni G, Mi R, Riahi K, Rogner H, Tavoni M
A collaboration of five state-of-the-art integrated energy-climate models show that increased natural gas consumption and substitution of coal by natural gas is unlikely to have significant climate benefits and , more likely, will increase greenhouse gas emissions from the energy sector.

Assessment and risk analysis of casing and cement impairment in oil and gas wells in Pennsylvania, 2000–2012

PNAS
30 Jun 2014
Anthony R. Ingraffea, Martin T. Wells, Renee L. Santoro, and Seth B. C. Shonkoff
Previous research has demonstrated that proximity to unconventional gas development is associated with elevated concentrations of methane in groundwater aquifers in Pennsylvania. To date, the mechanism of this migration is poorly understood. Our study, which looks at more than 41,000 conventional and unconventional oil and gas wells, helps to explain one possible mechanism of methane migration: compromised structural integrity of casing and cement in oil and gas wells. Additionally, methane, being the primary constituent of natural gas, is a strong greenhouse gas. The identification of mechanisms through which methane may migrate to the atmosphere as fugitive emissions is important to understand the climate dimensions of oil and gas development.

A new look at methane and non-methane hydrocarbon emissions from oil and natural gas operations in the Colorado Denver-Julesburg Basin

Journal of Geophysical Research - Atmospheres
08 May 2014
Gabrielle Pétron, Anna Karion, Colm Sweeney, Benjamin R. Miller, Stephen A. Montzka, Gregory Frost, Michael Trainer, Pieter Tans, Arlyn Andrews, Jonathan Kofler, Detlev Helmig, Douglas Guenther, Ed Dlugokencky, Patricia Lang, Tim Newberger, Sonja Wolter,
The study revisits the estimates of hydrocarbon emissions from an oil and gas basin using airborne measurements and finds that inventories underestimate hydrocarbon emissions in the basin by a factor of 2 or more.

Spatially Explicit Methane Emissions from Petroleum Production and the Natural Gas System in California

Environmental Science & Technology
23 Apr 2014
Seongeun Jeong,* Dev Millstein, and Marc L. Fischer
This study presents a spatially-resolved methane inventory for the state of California based on EPA emission factors and compares the estimated emissions to atmospheric measurements. The study finds that the EPA's methane emission estimates for natural gas transmission and distribution are too low by a factor of 2.

Kovats S, Depledge M, Haines A, Fleming LE, Wilkinson P, Shonkoff SB, Scovronick N
What is known about the health effects of gas extraction by induced hydraulic fracturing of gas-bearing rock—ie, fracking? A workshop held on Nov 15, 2013, at the London School of Hygiene and Tropical Medicine and attended by scientists, public health professionals, and decision makers addressed this question.
