a. Description of fracking Fracking is often also called hydro fracking‚ hydraulic fracturing‚ shale oil or shale gas. This technology can be defined as the process of extraction of oil and gas by providing a of sand‚ water‚ and chemicals injected at high pressures vertically and horizontally to the bottom layer of rock in which oil and gas are trapped. Hillard Huntington et al.2013 Fracking was developed to get the remnants of oil contained in production wells‚ especially in old oil wells. This

Show me‚ Tell me Questions and Answers Q1) Show me how you would check that the direction indicators are working. A1) Applying the indicators or hazard warning switch and check functioning of all indicators. (may need to switch ignition on‚ prompt not to start engine) TIP- Most cars will not need to have the ignition switched on to activate the hazard switch‚ so it should be simple to lean into the car‚ switch it on‚ walk around the car checking all 4 main indicators (there are also indicators

Will Fracking Suffocate Earth?! Student Name: Pang Jian Jie (JJ) Student Number: 21373411 Tutorial Day/Time: Friday/12-2pm Tutor’s Name: Luis Parra Avila Word Count: 967 Hydraulic fracturing‚ also commonly known as “fracking”‚ is a method often used nowadays to extract natural gas. The process starts when a steel pipe casing is inserted into the drilled well bore. Tiny holes are made in the pipe in order to let the fracturing fluid flow into the zones which contain oil or gas. Eventually‚

Fracturing of America Even though Hydraulic Fracturing is changing our dependence on fossil fuels‚ it could very well be changing our most precious resource‚ our water supplies. The average fracturing site uses an estimated 70 to 140 billion gallons of water to fracture 35‚000 wells in the United States annually. This is approximately the yearly water consumption of 40 to 80 cities each with a population of 50‚000. This water is infused with chemicals that seep back into our groundwater and contaminate

glass of water‚ you go to the tap and instead of fresh clean water you get yellow‚ cloudy‚ oily water that smells of chemicals. Would you drink it? Those that live near natural gas hydro-fractured wells have had to ask themselves that question. Hydraulic fracturing or fracking‚ as it’s commonly called‚ is a process of extracting natural gas from deep within the earth’s surface by drilling. Once a well is drilled‚ millions of gallons of water‚ sand and chemicals are injected‚ under high pressure‚

“Hydraulic Fracturing or Fracking is a process in which fractures in rocks below the earth’s surface are opened and widened by injecting chemicals and liquids at high pressure”(Dictionary). This type of mining is used to extract natural gas and oil by drilling a mile or more below the surface. Fracking has been “commercially used for 65 years”(Introduction)‚ supplying Americans energy. Hydraulic Fracturing has allowed for the increase in supplies of oil and natural gas. It is currently the best and
