Transcript of Hydraulic Fracturing

The dictionary definition is ‘the forcing open of fissures in subterranean rocks by introducing liquid at high pressure, especially to extract oil of gas.’ (Google, 2014).
What problem is fracking attemping to solve?
Extensive dependence on fossil fuels
Increased fuel electricity prices
Inflation
How does it work?
Plant location ideal
Drilling wells about 1-2 miles vertically until reaching rock then horizontally for another 1 mile.
Cased in steel piping
Fluid - Water, guar, nitrogen, detergents, lubricant, proppants, enzymes, etc...
Over 600 chemicals used (Mercury, Methanol, Uranium, Radium, etc...)
What is it?
Advantages:
Produce more natural gas and can be converted for fuel for cars and electricity.
No fluctuation of prices
Land usable after a year or so
No disruption of urban lives
Interaction with Environmental factors:
Risk of fluid spillage during transport to site. Toxic chemicals destruction.
Contamination of underground city water wells. Serious health hazard for plants being watered, also a serious health hazard.
Water used by 35,000 wells is 70-140 billion gallons. Same amount also used by 40-80 cities with populations of 50,000.
0.5-2 % of toxic chemicals in fracking mixture. '4 million gallon fracking operation[, it] would use from 80-330 tons of chemicals' (Earthworks Action 2014)
Disadvantages:
98-99% mixture is water and sand and others are toxic chemicals.... BUT compare it to when the mixture if 8-10 million gallons.
90% of mixture remains under water, moves along with fissures and contaminate.
Each Frack:
500 gallons of natural gas extracted
40,000 gallons of chemicals
400 tanker trucks
without scientific research we would be endangering lives of workers and others
Considering elements put in fluid to reduce risk of water contamination and risking a vast number of people's lives.
Components used in fracking fluid and how it helps them
Safety procedures
Endangering lives of workers
