Methane leaks from natural gas systems follow extreme distributions

Natural gas production site equipment with methane leak shot with a FLIR camera.

Even relatively small leaks from the natural gas system can create large climate concerns because natural gas is comprised mostly of methane (CH 4 ), a gas with high global warming potential (GWP, ~34 times that of CO 2 over 100 years, ~86 times on a 20-year basis). Using a very big sample, this study …

Upward revision of global fossil fuel methane emissions based on isotope database

Graph showing the revised and much higher than previously assumed amounts of methane emissions to the atmosphere.

By revising the isotope source signatures this study finds that total fossil fuel methane emissions (fossil fuel industry plus natural geological seepage) are 60 to 110 per cent greater than current estimates suggest. Abstract Methane has the second-largest global radiative forcing impact of anthropogenic greenhouse gases after carbon dioxide, but our understanding of the global …

Whistleblower: EPA Official Covered Up Methane Leakage Problems Across US Natural Gas Industry

Inspector General has been called by Durham, North Carolina, based group NC Warn to investigate scientific fraud that wasted crucial years in slowing climate crisis while risking safety of workers and communities. NC WARN filed a complaint with the Inspector General of the EPA on June 8, 2016, charging that a high-ranking EPA official connected …

Anthropogenic and natural methane emissions from a shale gas exploration area of Quebec, Canada

Here methane emissions, computed from four potential sources (i. e. 1) groundwater degassing as a result of groundwater abstraction for domestic and municipal uses; 2) groundwater discharge along rivers; 3) migration to the surface by (macro- and micro-) diffuse seepage; 4) degassing of hydraulic fracturing fluids during first phases of drilling.), are reported for an …

HEALTH CONSULTATION – Dimock Groundwater Site

Based on groundwater samples taken in Dimock, PA, during a completion (i. e. fracking) moratorium in 2012, which contained a plethora of health affecting chemicals, the ATSDR comes to the conclusion that consumption of that water might or does pose a significant risk for human health and that in some instances, due to its methane …

Aerial surveys of elevated hydrocarbon emissions from oil and gas production sites

For this study the researchers performed helicopter-based infrared camera surveys of more than 8,000 O&G well pads in seven U.S. basins to assess the prevalence and distribution of high-emitting hydrocarbon sources. Key findings: The proportion of sites with such high-emitting sources was 4% nationally but ranged from 1% in the Powder River (Wyoming) to 14% …

Contribution of oil and gas production to renewed increase in atmospheric methane

This new study corroborates the evidence that the current oil and gas production boom is driving the increased presence of the powerful green house gas methane in the atmosphere. Besides increased methane emissions from tropical wetlands, the previously grossly underestimated rate of leaking methane from fossil fuel production, namely by hydraulic fracturing (“fracking”), is aggravating …
