May 7, 2013 - Hydraulic fracturing is seen as a game-changer in world energy markets. “Fracking” is a two-phase process to extract natural gas from prehistoric shalebeds thousands of metres below ground. The first phase includes drilling the wells, while the second uses high-pressure blasts of water and sand-laden gel to fracture shale rock and release gas.
