I found a broader article on the increasing costs involved in water-based fracking and possible alternative solutions.

Dr Kent Moors who wrote this article has a very big following in the energy investing sector. I don't necessarily agree with everything he has to say... but a lot of people do follow his investing ideas. If he were to recommend Gasfrac it would attract a lot of interest.
