Natural Gas Fracking Linked to Earthquakes
A University of Texas study has found more seismic activity in areas near Dallas where natural gas drillers have built high-volume injection wells to handle drilling wastewater.
“A study published in the Proceedings of the National Academy of Sciences finds a correlation between dozens of small earthquakes in Texas’ Barnett Shale region—the site of intensive hydraulic fracturing activity—and the locations of injection wells used to dispose of the wastes of this process. ”You can’t prove that any one earthquake was caused by an injection well,” says Cliff Frohlich, the University of Texas geologist who conducted the study, “but it’s obvious that wells are enhancing the probability that earthquakes will occur.”
“The good news is that all of these earthquakes were still relatively small, with magnitudes of less than 3.0 on the Richter scale, unlikely to cause any damage on the surface.”
That’s not good news, that’s “great” news. Looks like Tommy Lee Jones was right, “Let’s get behind the Barnett Shale.”
