New Study Finds Well Casings, Not Fracking, Cause Methane Migration
Another new “study” and already the headlines are blaring. A research team led by Ohio State University and composed of researchers at Duke, Stanford, Dartmouth, and the University of Rochester have just published their findings that methane migrates from some shale wells into local water wells. It certainly doesn’t sound like earth-shattering news, but the headlines across the country range from “Bad fracking wells taint water, scientists find” (Sacramento Bee) to “Weak wells not fracking caused US gas leaks into water” (BBC). The media has picked up on this latest study and, depending on the view of the reporter, has spun it to either say fracking is the culprit, or fracking isn’t the culprit–and just about everything in between. Once again MDN will break it down for you and tell you what the study really says. And, we have a copy of the published findings (embedded below) so you can read it for yourself and make up your own mind…

Hack “researchers” will collect research others have done, run some numbers in a spreadsheet to bias the outcome, and then make off-the-wall pronouncements like burning coal is less damaging to the environment than drilling for natural gas (see 
Long before the words “Marcellus” and “Utica” entered the public discourse and consciousness of Ohioans, there was the Clinton Sandstone. For years conventional drillers have been sinking wells in the Clinton, which is found 4,500 feet below the surface (the Marcellus and Utica Shale layers are deeper). The Clinton lies under 25 counties in eastern Ohio. Over the years, some 35,000 conventional (vertical) wells have tapped the Clinton Sandstone in Ohio. EnerVest, one of the largest acreage holders in the Utica Shale (and in the Clinton Sandstone), has embarked on a great experiment. What if you turned a Clinton Sandstone well horizontal, like a Utica or Marcellus well? Would it work? Could you get more gas out of the sandstone by fracking it like shale? EnerVest has drilled seven horizontal wells so far, with a permit to drill another and a request to drill a ninth. Here’s the details, along with the differences between a Clinton horizontal well and a Utica horizontal well…
In the summer of 2012, the U.S. Geological Survey (USGS) began a groundwater survey in Pike County, PA. Pike, located in northeastern PA, is one of the counties with the dubious distinction of being under the regulatory purview of the Delaware River Basin Commission which has, so far, refused to allow any Marcellus Shale drilling. The survey’s purpose is to provide baseline numbers prior to any Marcellus drilling activity. So, just to be clear, there has been NO drilling thus far in Pike nor anywhere near Pike. And yet, what did the USGS survey, published in July 2014 (full copy below) show? Some 80% of the water wells tested in Pike have “detectable concentrations of methane” and 10% of the wells (2 of the 20 tested) have high levels of methane. Not only that, 85% (!) of the wells tested have (gasp) really high radon levels–over the proposed safe limit of 300 picocuries per liter. One well was as high as 4,500 picocuries! But it gets worse–there’s also measurable quantities of nasty stuff like barium, strontium, and the dreaded chloride (salt). And yet, not a Marcellus Shale well in sight. Now how can that be?…
