Study Claims Link Between Fracking & Earthquakes in W Canada

fracking-and-earthquakes.jpgAnother week, another so-called research paper that purports to show a link between fracking and earthquakes. Two researchers at the University of Calgary looked at drilling and fracking of shale wells in Canada’s Duvernay Shale (western part of the country), looking for clues that might indicate fracking itself–if done near an underground fault–can lead to low-level earthquakes. The researchers claim they have found such a link–which is the first such study to make a connection between fracking and earthquakes. The researchers have just published “Fault activation by hydraulic fracturing in western Canada” (full copy below), in the journal Science. We have repeatedly reported, based on studies and observable facts, that disposing of high volumes of wastewater in injection wells near underground faults (large cracks in the rock layer) can lead to earthquakes. We’ve also chronicled that fracking directly over a fault can also lead to an earthquake–which has been documented to happen perhaps half a dozen times, ever, out of the hundreds of thousands of times wells have been drilled and fracked. Statistically zero. But this study claims there is a link and the inference is that fracking leads to more earthquakes that you may think. Should we be worried?…
