Hydraulic fracturing by country - Wikipedia
Hydraulic fracturing by country - Wikipedia

Fracking has been in common use by the petroleum industry in Canada since at least the mid-1960s. Massive hydraulic ,fracturing, has been widely used in Alberta since the late 1970s to recover gas from low-permeability sandstones of the Spirit River Formation. The method is currently used in development of the Cardium, Duvernay, Montney and Viking in Alberta, Bakken in Saskatchewan, Montney and ...
