Wow! Fast Eddie must really want this to go through...he's got regulators lying through their teeth. Many of the compounds used in fracking weren't even around in the 50s. (And Halliburton and BJ claim they stopped using diesel fuel in fracking fluids two years ago. :-)
Yeah, there are some pretty bold statements being thrown around and I imagine you know the players better than me. I am not sure if they were fracking anywhere in the 50’s, at least not at the scale they do today. Maybe he is referring to when they used to drop dynamite down a hole?
Anyway, I am still not finding any site specific information that is easily accessed from the internet. Still an interesting problem so I will keep looking.
