Fracking involves drilling wells in shale deposits, then pumping in water and other additives at high pressure to break the rock and release trapped oil. In some regions fracking can trigger earthquakes by causing faults in the rock to slip.
Why are earthquakes associated with hydraulic fracturing?
Reports of hydraulic fracturing causing felt earthquakes are extremely rare. However, wastewater produced by wells that were hydraulic fractured can cause “induced” earthquakes when it is injected into deep wastewater wells. A combination of many factors is necessary for injection to induce felt earthquakes.
How does fracking affect tectonic plates?
The U.S. Geological Survey has maintained that fracking is not the cause of most induced earthquakes. Eaton and his co-author Xuewei Bao demonstrated hydraulic fracturing itself caused earthquakes in western Canada, by adding pressure to tectonic faults. When the pressure builds up enough, the tectonic plates slip.
What are benefits of fracking?
Fracking Has Great Benefits The process has steadily increased oil and natural gas production in the United States. As a result, it has lowered energy prices, improved air quality due to reduced carbon dioxide emissions, and improved the country’s energy security.
What do you get from fracking?
Fracking is a proven drilling technology used for extracting oil, natural gas, geothermal energy, or water from deep underground.
What is the purpose of fracking?
Fracking allows drilling firms to access difficult-to-reach resources of oil and gas. In the United States it has significantly boosted domestic oil production and driven down gas prices.
How does fracking create jobs?
Direct jobs in producing states include construction, oil and gas extraction, metal fabrication and truck transport. In non-producing states, directly created jobs include the manufacture of chemicals, equipment and electronics used for fracking.
What is fracking advantages and disadvantages?
