Liquid CO2 is the next generation of fracking method, generated by existing power generation systems. Pumping the cryogenic fluid creates fracturing by temperature change, and much of the CO2 becomes a carbonate, being sequestered underground while leaving channels for upward flow of the oil.

Fracking water is only now reaching effective management, with recovery and reuse. Water that comes up with the oil is a remnant of ancient seas, and brings up minerals like lithium and cobalt, that can be concentrated out far cheaper than by mining. Recovered minerals promises to bring down the cost of batteries significantly once widespread use of the technology comes into play.

The shale oil fields, not long ago deemed impossible to exploit, are turning out continuing surprises.

Ellis Wyatt knew this many years ago. At that point the cost of oil was cheap enough that no one else bothered to extract oil in the way he did.

Darn! I was hopping that the sand under the pool I just go rid of was worth something...oil isn't gona flow through "Dead sand"...

I wonder, Blair...if we could use those politicians instead of sand...might be worth a try!

I guess I'm missing something...what, exactly, are they going to do with all this sand?
