Study: 4 of 10 Fracked Wells in PA Projected to Fail

From The Energy Collective:
A major new study finds that, as suspected, it is new, unconventional gas wells that are far more likely to leak heat-trapping — and tap-water igniting — methane than older, conventional wells. 
After examining the publicly available compliance records of more than 41,000 wells in northeastern Pennsylvania, the Cornell-led researchers have dropped this bombshell:

About 40 percent of the oil and gas wells in parts of the Marcellus shale region will probably be leaking methane into the groundwater or into the atmosphere…. This study shows up to a 2.7-fold higher risk for unconventional wells — relative to conventional wells — drilled since 2009. 
Study after study has found consistently higher methane leakage rates from natural gas production and distribution than reported by either the industry or EPA (which uses industry self-reported data).
