Methane emissions and climatic warming risk from hydraulic fracturing and shale gas development: implications for policy

Abstract: Over the past decade, shale gas production has increased from negligible to providing >40% of national gas and 14% of all fossil fuel energy in the USA in 2013. This shale gas is often promoted as a bridge fuel that allows society to continue to use fossil fuels while reducing carbon emissions since less …

Towards a Road Map for Mitigating the Rates and Occurrences of Long-Term Wellbore Leakage

Towards a Road Map for Mitigating the Rates and Occurrences of Long-Term Wellbore Leakage Key findings: “… the severity of the problem is not known because neither industry or oil and gas regulators are collecting the data.” Natural gas seeping from 500,000 wellbores represent “a threat to environment and public safety” due to groundwater contamination, …

CO2, Methane, and Brine Leakage Through Subsurface Pathways: Exploring Modeling, Measurement, and Policy Options

Subsurface pathways, such as abandoned oil and gas wells and faults, can serve as leakage pathways for CO2 , methane, brine, and other fluids. These pathways allow fluids from deep subsurface formations to migrate into shallow groundwater aquifers or to the atmosphere. Between 200,000 and 970,000 abandoned wells in the state of Pennsylvania likely account …

Methane Leaks from North American Natural Gas Systems

Key findings: First comprehensive look at North American methane emissions: Review of more than 200 studies with conflicting methodologies finds that “Atmospheric tests covering the entire country indicate emissions around 50% more than EPA estimates. And that’s a moderate estimate.” Methane leaks negate the climate change benefits of using natural gas as a transportation fuel: …

Determining the origin of methane and its effect on the aquifer in Dimock Gesford 2 well

These slides make the link between hydraulic fracturing (“fracking”) for shale gas in Dimock, PA, and groundwater contamination. “Methane is released during the drilling and perhaps during the fracking process and other gas well work.” Bibliography: U.S. Environmental Protection Agency (EPA) Isotech-Stable isotope analysis: Determining the origin of methane and its effect on the aquifer in Cabot Oil and Gas’ Dimock Gesford 2 well EPA, …
