What is fracking in geography for kids?
Fracking, or hydraulic fracturing, is a technique in which a fluid is injected at high pressure into an underground rock formation in order to open fissures, or cracks, and allow trapped gas or crude oil to flow through a pipe to a wellhead at the surface.
Is fracking used in Canada?
In Canada, more than 200,000 wells have been horizontally fracked for shale gas or oil, primarily in the western provinces. It is now estimated that 80 per cent of new oil and gas wells in Canada are fracked.
How is fracking performed?
Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Water, sand and chemicals are injected into the rock at high pressure which allows the gas to flow out to the head of the well.
What are 5 steps in the process of fracking?
Drilling and the Hydraulic Fracturing (Fracking) Process
- Preparation. Preparing a drilling site involves ensuring that it can be properly accessed and that the area where the rig and other equipment will be placed has been properly graded.
- Well Completion.
- Well Abandonment.
Why is fracking a bad thing?
Hydraulic fracturing, or “fracking,” is revolutionizing oil and gas drilling across the country. However, without rigorous safety regulations, it can poison groundwater, pollute surface water, impair wild landscapes, and threaten wildlife.
What is fracking in Canada & is fracking bad?
Fracking in Canada | What is Hydraulic Fracturing & Is Fracking Bad? Hydraulic fracturing, known as fracking, is a technology and process used to recover oil or natural gas trapped in non-porous or “tight” rock formations such as shale – these formations were previously too expensive to produce efficiently.
How is fracking used in the United States?
By accessing tight oil and tight gas, the sophisticated technologies used in fracking are rapidly expanding petroleum and natural gas production in the United States. This video explains the technology of fracking using the example of the Iverson oil well, which drills into the Bakken shale formation near Williston, North Dakota.
What is hydraulic fracturing?
See how hydraulic fracturing, or fracking, releases petroleum or natural gas trapped in shale rock formations. The process of fracking for natural gas and oil is explained with an example from North Dakota, an area where the number of fracking wells is expected to greatly increase in the coming years.

What is the process of fracking?
In the fracking process, cracks in and below the Earth’s surface are opened and widened by injecting water, chemicals, and sand at high pressure. Some resources extracted through fracking are called “tight oil” or “tight gas,” because these pockets of fossil fuels are tightly trapped in hard shale rock formations.
