Next, a delayed release gel ,breaker, is added to the frac ,fluid,. In the final flush stage, another gel ,breaker is used, to convert the thick gel into a liquid. All of the ,fluid, is then drained, leaving only the proppants behind so that the cracks created by the pressurized elements remain open for gas or oil to flow to the wellbore. Id. at 7.

Shales are primarily frac'd using a type of ,fluid, system called "slickwater". The primary chemical additive in slickwater is a ,kind, of polymer friction reducer that causes the the ,fluid, to flow in a laminar (as opposed to turbulent) flow regime at high rates (ie 4200gpm/100bpm). In the shale plays the ,fluid, systems don't have a lot of complexity.
