petro fraccing

Does anybody here have any up to date knowledge on using petroleum based fraccing fluids as compared with water based chemically treated fraccing fluids? Seems there are coys in usa going gangbusters in new petro fraccing which has the potential to increase the horizontal length of well with fractures open longer with higher production of oil gas /50%more/ with no expensive treating of used water based frac fluid in order to dispose of said water fluid or reuse of water in drilling .Petro fraccing solution is assimilated with oil and gas and is cheaply recoverable and can be used again .Pertoleum based fluid for fraccing has the potential to save massive cost on drill fraccing with huge upside on the environmental front . Any research info ould be greatfully appreciated . It may be worth our wait if TB can get one of these new age petrofrac coys to do our current wells with an upside in greater long term production from our wells with less environmental contamination risk with potential to extract more oil per unit possibly 50% more oil and gas.
