Title:Environmental Impacts of Shale Gas Extractionin Canada Author: Council of Canadian Academies Publisher: Council of Canadian Academies Date: 2014 Full Text Article Summary: The North American energy landscape is undergoing dramatic change. Unconventional oil and gas resources are fuelling an energy boom that is having profound economic, environmental, and social
Fracking is a safe and innovative way to harness otherwise inaccessible shale gas as a form of incredibly efficient energy.
Hydraulic fracturing, or “fracking,” is a decades old well completion technology that is often coupled with horizontal drilling to develop oil and natural gas resources from tight rock formations. Fracking occurs after drilling has been completed and involves pumping fluid — typically 99 percent water and sand, with an additional mixture of chemical additives — into the target formation at pressure in order to open up small fractures in the rock, which allow oil and gas to flow out of these tight formations.
