Note the following advantages;

"LPG. The fluid still carries sand or ceramic particles to prop open the fractures, but contains no other chemicals.



When the water is pumped into the borehole, often up to 50 percent remains in the deposit and it impedes the extraction of natural gas.

When LPG is used, almost 100 percent of the LPG is recovered and the borehole is free of barriers.

Natural gas flow rates from LPG fracking are considerably higher than water-fracked wells.

In the case of an oil-bearing deposit, the LPG fracking fluid helps dissolve and thin the oil, thus making it easier to pump out.

Finally, the materials cost of natural gas fracking under LPG is considerably lower.

Since no fresh water is used, no domestic source is required and there is no water treatment needed for the recovered fracking fluid. "

.... so, everything recycled.

Not too sure on volume of LPG required for the operation, but will research on this.
