Abundant Natural Gas From Shale, Without Water Pollution ?

Apparently it is possible for the U.S. to have its energy cake and eat it too : abundant natural gas from shale without having to consume or pollute large quantities of water through the process of hydraulic fracturing or 'fracking' ( see figure to the right).

In place of water, gas fracturing or 'Gasfrac' employs LPG (liquid petroleum gas) in the extraction process, is nearly pollution-free, and far less destructive to the geological formations involved than its hydraulic counterpart, as Nawar Alsaadi explains in a recent SEEKING ALPHA post, Gasfrac Energy Services: Fracturing Game Changer .
