The commission has started what it calls "yellow-light permitting," with extra restrictions and extra attention from inspectors, and the ability to shut down a well if it is deemed to have caused an earthquakes. "It makes it a little harder for the industry to permit wells," Soraghan said, but only disposal wells, not production wells. "A handful of wells have been shut down," he says, but the measure doesn't apply to existing wells.
Soraghan also discusses his story revealing that scientists at the Oklahoma Geological Survey "suspected as far back as 2010 that a big swarm of earthquakes around Oklahoma City was related to oil and gas production, but they were not saying that publicly, and they rejected those findings when other scientists came out." He said one reason for that may have been that when the state seismologist started to agree with those findings, "He was called into meetings with the president of the university where he works," and in one meeting was Harold Hamm, chairman of Continental Resources, "a looming figure in the state."
