I know fracking too. This is a well being fracked on the North Slope. There are five turbine driven PD pumps in this picture pumping frack fluid downhole at about 8,400 psi. The frac fluid had a pH of 12 and contained bacteria I added to digest the thickening agents to prevent well skin...

Fracking is the process of pumping downhole, the wellbore, a liquid, primarily produced water (brine) with a thickening agent to carry sand at very high pressures. Usually the thickening agent and sand are very pure so as not to contaminate the wellbore. This mixture is pumped under very high...

Here is a map showing the faults in the area of the earthquake swarm which is still continuing. There appear to be many thrust faults in the area. What is interesting is that most of the recent southern California earthquakes have occurred in these thrust faults. Thrust faults are mapped by...
