Hydraulic fracturing, or fracking as it’s more commonly referred to, is used to stimulate the production of oil and gas from unconventional oil and gas deposits – shales, coalbeds, and tight sands. These types of deposits need to be stimulated because they have a lower permeability than conventional reservoirs and require the additional stimulation for production.
Hydraulic fracturing involves drilling a well then injecting it with a slurry of water, chemical additives and proppants. Wells are drilled and lined with a steel pipe that’s cemented into place. A perforating gun is used to shoot small holes through the steel and cement into the shale. The highly pressurized fluid and proppant mixture injected into the well escapes and create cracks and fractures in the surrounding shale layers and that stimulates the flow of natural gas or oil. The proppants (grains of sand, ceramic, or sintered bauxite) prevent the fractures from closing when the injection is stopped and the pressure of the fluid is removed.
Proponents of hydraulic fracturing argue that fracking:
- Creates cheap domestic energy
- Replaces dirty coal-fired power plants
- Makes it easier to meet federal air and water quality standards
- Reduces our dependence on foreign supplied oil
“Fracture stimulation is a safe and environmentally sound practice based on the industry’s decades-long track record, as well as the conclusions of government and industry studies and surveys.” Halliburton, a major corporate proponent of fracking
