Description of Dr. Dusseault’s Patent on Canadian Intellectual Property Office website:
As well, concerns have been expressed regarding the potential environmental impact from the use of synthetic additives in hydraulic fracturing solutions.
In one aspect, the fracturing fluids employed in this process comprise of water, saline or water/particulate slurries that are essentially free of additives.
 The terms “induced fracture” or “generated fracture” as used herein mean: a fracture or fractures created in the rock formation by man-made hydraulic fracturing techniques involving or aided by the use of a hydraulic fluid, which in the present process is intended to be clear water along with additives such as friction reducers to aid the hydraulic fracturing process.
 The term “slurry” as used herein means: a mixture a granular material sand/proppant along with clear water, which may or may not have additional additives for friction control and fracture development control. [Emphasis added]
