Researchers use satellite data to quantify methane emissions from the Bakken, Eagle Ford, and Marcellus basins (USA).
Assessment and risk analysis of casing and cement impairment in oil and gas wells in Pennsylvania, 2000–2012
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

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

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.
Toward a better understanding and quantification of methane emissions from shale gas development

The Health Implications of Fracking
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.
Methane Leaks from North American Natural Gas Systems
A. R. Brandt, G. A. Heath, E. A. Kort, F. O'Sullivan, G. Pétron, S. M. Jordaan, P. Tans, J. Wilcox, A. M. Gopstein, D. Arent, S. Wofsy, N. J. Brown, R. Bradley, G. D. Stucky, D. Eardley, R. Harriss
This study examines recent estimates of methane leakage, which have challenged the benefits of switching from coal to natural gas.
Natural Gas Pipeline Leaks Across Washington, DC
Environmental Science and Technology
Jackson, Robert B., Adrian Down, Nathan G. Phillips, Robert C. Ackley, Charles W. Cook, Desiree L. Plata, and Kaiguang Zhao
This study presents sampling results of methane leakage from the natural gas distribution system in Washington DC. 12 of the 19 locations tested showed concentrations hig enough to risk explosion.
Life Cycle Assessment (LCA) of Electricity Generation Technologies: Overview, Comparability and Limitations
Renewable and Sustainable Energy Reviews
Turconi, Roberto, Alessio Boldrin, and Thomas Astrup
This study presents a review of 167 case studies involving the life cycle assessment (LCA) of electricity generation based on hard coal, lignite, natural gas, oil, nuclear, biomass, hydroelectric, solar photovoltaic (PV) and wind to identify ranges of emission data for GHG, NOx and SO2.
