The Methane Mafia has been misleading the public about how safe Fracking is, because they have been hiding the truth about frack jobs that go “out of zone”, or that “communicate” with old & abandoned wells by repeating the same lie that “fracking has never contaminated a private well” – so here is how it can happen.
Study Targets Methane Leaks Between Underground Wells
Hydraulic fracturing can form cracks that can connect new shale gas wells to nearby abandoned wells, possibly allowing methane to leak into the atmosphere or aquifers underground, according to a University of Vermont study published this week.
The study is one of the latest efforts to answer an elusive question: How do fracked oil and gas wells leak methane and other hydrocarbons into underground aquifers and into the atmosphere?

Previous research has shown that shale gas drilling and production may leak a large but not fully known amount of methane into the atmosphere, possibly up to 1,000 times more methane than previously thought. The U.S. Environmental Protection Agency has proposed rules to curb methane emissions from oil and gas wells and pipelines, seeking to slash emission from the oil and gas industry by up to 45 percent below 2012 levels over the next decade.
Abandoned gas wells in the Marcellus shale in Pennsylvania have been found to leak methane, but nobody knows yet how many wells leak and how much methane they’re emitting.
Montague studied Marcellus shale wells in New York, calculating the probability that tiny rock fractures created by the hydraulic fracturing process would eventually intersect the underground borehole of an abandoned gas well or cracks connected to it. READ MORE
