Gaz de schiste: infos Industry and government repeatedly claim that hydraulic fracturing is safe because it is a well-regulated technique proven in the field over 60 years.

It that myth or reality?

A good person to ask is Anthony Ingraffea, a short and engaging scientist who knows how to separate fact from fiction in the shale gas industry.

On Dec. 14 of last year the Cornell University engineer, one of the world’s foremost authorities on the science of hydraulic fracturing, gave a stunning talk on the myths and realities of unconventional shale gas development to a room full of Calgary academics and oilmen.

He did so with some trepidation in the oil and gas city, even though he has given some 120 public talks on the subject over the last four years to rural and urban audiences.

« The playing field isn’t level, » he told the Tyee. « Oil and gas companies are tremendously wealthy and have very loud speakers. They can buy TV and full page ads and place them wherever they want. »

As a consequence, Ingraffea feels it is his duty as a scientist to provide missing information, challenge outright lies, and expose the uncomfortable science about mining methane from shattered rock.
