Fracking
Hydraulic Fracturing or Fracking
- The process of injecting liquid at high pressure into subterranean
rocks, boreholes, etc., so as to force open existing fissures and extract
oil or gas
Shale sediments are held together by a weak force called Van der Walls
force – think of it like static electricity
Water and nutrients in the soil
- Large pore spaces allow water and nutrients to move quickly
- Small pore spaces tightly hold onto water and nutrients
Fossil fuels are made from dead things
Soap works because one end of the molecule is hydrophilic (water
attracting) and the other end is hydrophobic (water repelling)
Soap surrounds the fats and whisks it away with flowing water
So what kind of soap is hydraulic fracturing fluids?
- We do not know as oil companies have proprietary rights over their
fluids composition
What is done with the fluids after they are used
- They are pumped back into the ground and left there
Where is most fracking done in the US?
- Texas
