Fracking study finds new gas wells leak more
2014-07-01 14:41:23| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: In Pennsylvania's gas drilling boom, newer and unconventional wells leak far more often than older and traditional ones, according to a study of state inspection reports for 41,000 wells. The results suggest that leaks of methane could be a problem for drilling across the nation, said study lead author Cornell University engineering professor Anthony Ingraffea, who heads an environmental activist group that helped pay for the study. The research was criticized by the energy industry. Marcellus...
Study Digs Deep on Shale Gas Wells, Methane Leaks
2014-06-30 22:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Defects in fracked oil and gas wells in Pennsylvania are leading to methane leaks in shale wells throughout the state -- greenhouse gas emissions that could exacerbate climate change, according to a Cornell University study published Monday. The study, conducted by a team led by Cornell environmental engineering professor Anthony Ingraffea, analyzed more than 75,000 publicly available state environmental compliance records for about 41,000 oil and gas wells that had been drilled between 2000 and...

Princeton Study: Up to 900,000 Abandoned Oil and Gas Wells Pollute Pennsylvanias Air
2014-06-19 17:22:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: Pennsylvania already has a fracking problem groups struggle to inspire politicians to address. Now, a Princeton University study shows that hundreds of thousands of abandoned oil wells are adding to the state`s pollution. CO2, Methane, and Brine Leakage through Subsurface Pathways: Exploring Modeling, Measurement and Policy Options is a first-of-its-kind study from Mary Klang that describes how abandoned oil wells serve as leakage pathways for carbon dioxide, methane, brine and more. Based...
