We have earthquakes but they are getting fewer and fewer. It has been determined that they are not caused by the oil wells and fracking, but by salt water disposal wells in the Arbuckle formation which is the deepist sedimentary formation on Oklahoma just above bed rock. To much water disposed in this formation near falt lines causes premature release of stress in the faults thus causing earthquakes.
The Oklahoma Corporation Commission has taken steps to reduce volumes and in some cases shut down disposal into the Arbuckle and it is haviing a very marked effect on the number and intensity of earthquakes. I suspect it will take a while to rid us of all of them but it is obvious that we are going in the right direction.
The days of Spindletop are gone, sadly. Volume wise, is their really much difference between salt water injection and fracking? The water injection has been done for many decades and people, I mean media idiots, seem to think it is something new.
