Key takeaway points

  • Hydraulic fracturing has revolutionised oil and gas output in the United States.
  • A mix of water sand and chemical additives is pumped into the well bore to stimulate the release of the product..
  • The mix of fracking fluid is mostly water, but it also includes a small proportion of chemical additives. Some of the additives are highly toxic and need to be managed extremely carefully.
  • At the depths where fracking occurs the rock is impermeable. The distance is several thousand feed below ground level, which much lower than the levels containing ground water.
  • Useful websites covering arguments both for and against  the process include; http://shalegas-europe.eu/shale-gas-explained/the-process-of-shale-gas-development/     http://www.dangersoffracking.com/
