Transcript of Hydraulic Fracturing

Hydraulic Fracturing commonly referred to as fracking a process by which wells can be used to extract energy resources with high efficiency used in obtaining oil, gas, water, and geothermal forms of energy History 1903- introduced 1948- commercialized 1974- Safe water drinking act 1988- over a million known applications of fracking 1900 2004- coalbed fracturing causes no harm to drinking water 2007- explosion in Ohio 2002- fracking determined to not have detremints to water, but raises concerns of using diesel fuel 2005- bipartisan energy bill 2009- increased opposition to fracking 2011 Infrastructure Social/economic impact Many people angered by harmful effects to the environment and to human resources Limitations and banning of fracking have been pushed for recently Safety Would cost State Treasuries $785 million if fracking was banned Employs 1.2 million people Puts out over $250 billion per year as of 2007 If banned, domestic oil production would recede by about 183,000 barrels per day Safe water drinking act (1974) Well-regulated No proven water contamination in over one million applications 95% or more of the fracking fluid is water Studies by EPA, GWPC, IOGCC Versus Apr. 21, 2011: Hydraulic Fracturing suspended due to blowout June 3, 2010: Clearfield, PA.
35,000 gallons of fluid contaminate Physics behind it 90 percent of natural gas wells are "fracked" Can extract more than just natural gas:
geothermal energy
oil More effective when compared to a vertical drilling technique Lessens foreign dependency on fuels Increases domestic production of oil by 183,000 barrels per day 2 months Digging of a well laterally
Fractures from mini explosions within the casing
Fracking fluid pumped into wellbore
Filled with fracking fluid
Proppants keep fractures in place while water pumped out
Pressure causes natural gas to leak out through cracks
Pumped out and stored Precautions must be made in order to assure minimal damages Tyler Walsh
