    How Hydraulic Fracturing WorksIs Fracking Bad?Hydraulic Fracturing FluidsProtecting Groundwater During Hydraulic FracturingIndustry Guiding Principles For Hydraulic FracturingWater Use in Hydraulic Fracturing1. DrillingFirst, the well is drilled vertically. Unconventional natural gas reserves are typically found two to three kilometres below the earth’s surface, hundreds of metres deeper than drinkable groundwater. Once the vertical well reaches the target formation, the well is turned to drill horizontally through the formation. H2.Surface CasingNear-surface layers including soil and groundwater are protected by steel casing and cement that create a solid barrier between the well and underground water sources. Intermediate casing extends even deeper below any fresh water sources and provides an additional protective layer.3. Perforating the WellborePrior to fracturing, the wellborecasing is perforated so fracturing fluid can be forced out of the wellbore and into the rock formation, and so oil or natural gas can flow into the wellbore and be brought to the surface. Perforating causes initial cracks in the formation that are extended during the fracturing process.See more on capp.ca

    SummaryExamplesHistoryApplicationsOther usesPurposeOperationCompositionUseClinical significanceRisksImpactHydraulic fracturing is a procedure that can increase the flow of oil or gas from a well. It is done by pumping liquids down a well into subsurface rock units under pressures that are high enough to fracture the rock. The goal is to create a network of interconnected fractures that will serve as pore spaces for the movement of oil and natural gas to the well bore.See more on geology

    Hydraulic fracturing in Canada was first used in Alberta in 1953 to extract hydrocarbons from the giant Pembina oil field, the biggest conventional oil field in Alberta, which would have produced very little oil without fracturing. Since then, over 170,000 oil and gas wells have been fractured in Western Canada.
