Natural gas extracted from shale deposits and often referred to as an unconventional resource, continues to increase its share of the hydrocarbon offer, more specifically in North America, and is being more and more looked after by many countries around the world. In Quebec, Canada, for instance, exploration for shale gas started in 2006 in a geographical area where the geological potential was expected to be more significant but also were a large part of the territory is agricultural land and is inhabited by a large part of the province's population. But by 2010, public opposition to gas industry's activities was so widespread such that the government commanded a strategic environmental assessment to an expert committee in order to acquire more knowledge on the environmental, social and economical issues related to shale gas exploration, extraction and production.
