U.S. Methane Mitigation 2015: A Review of Climate and Public Health Impacts

PSE Healthy Energy
23 Jan 2015

Jan 14 2015 the U.S. EPA, in response to the Obama Administration's mandate for methane emission reductions, released its plan to cut emissions from the oil and gas industry by 40% - 45% from the 2012 baseline. Response to the proposal has been mixed with many environmental groups immediately applauding the measure before questioning the administration's narrow focus on new emission sources only.

There is an imperfect but very useful analogy between a gasoline piston engine, such as that of a car, and a natural gas well, such as those found in northeast Pennsylvania, from a performance integrity point of view. . .

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

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.
