The controversy around whether wastewater injection wells cause earthquakes was finally put to legal scrutiny in a recent proceeding before administrative hearing examiners with the Texas Railroad Commission, which regulates oil and gas production in the state. The Examiners found that an injection well owned by XTO Energy Inc. likely did not influence a series of earthquakes that occurred near the towns of Reno and Azle from late 2013 through spring of 2014.
