Jim Fuquay wrote an excellent Friday article on the Azle meeting involving Texas Railroad Commissioner David Porter (“No answers on area quakes”). I wasn’t at the meeting, but I understand the frustration felt by the attendees.
A study done at the Denver Rocky Mountain Arsenal and Rangely oil field in Colorado in the early 1960s is all the proof you need to indicate that injecting high volumes of liquid into the ground, not fracking, is causing the earthquakes in the Azle area.
I offer a simple solution: Continually reduce the volume of fluids being injected into the wells over time until the earthquakes cease. Thus, you can establish the proper volume of fluids that can be injected over any given period.
The Railroad Commission and owners of the injection wells should be prudent stewards of our environment and ease the tension that this activity has caused in the community.
