SHALE GAS: Alternative Fracking Methods.

As a matter of interest, there are alternate methods for fracking that do not have the same environmental impacts as the traditional methods. The following was brought to my attention by Bob Godfrey, Researcher at Save Passamaquoddy Bay.

GASFRAC Energy Services Inc. (Trading on the TSX-V as "GFS") GASFRAC Energy Services Inc’s. proprietary LPG (Liquefied Petroleum Gas) Fracturing Process utilizes gelled LPG in place of conventional fracturing fluids. The unique properties of the LPG fracturing process result in significant savings on material expenses and fracture clean up, as well as increased well productivity.

 The gelled LPG used in the fracturing process has the ability to both generate the necessary fracture system, carry the proppant through the wellbore and place into the oil and gas reservoir being stimulated.

The LPG used in the process is highly soluble in formation hydrocarbons. As a result, the LPG process results in less damage to formations than conventional hydraulic fracturing. And unlike conventional treatments where as much as 50% of the carrier remains in the reservoir and hinders well performance, virtually 100% of the LPG can be recovered.
