Transcript of Hydraulic Fracturing
What is our presentation about?
to get oil and gas
first experimental use was in 1947
like normal fracking - but revolutions in the last years
most fracking worldwide in the us
slurry of water, sand, and chemical additives
contamination of drinking water
accidents during transport
*partially already banned
German purity law
Experiments in Austria
inefficient and still wasteful
stricter licensing requirements
existing regulatory in Germany
permits without extensive environmental testing
we do not want to see the environment contaminated
thanks for your attention
Artur and Taco [HWR Berlin]
cracks by pressure / like explosions
fracturing fluids pumped back
sand remains in cracks to hold pressure
health risks etc.
related to methane leaks
emissions from the diesel
reports of health
fracking = microearthquakes
chemicals 80-300 t
radioactive material and heavy metals
50-80% of toxic waste fluids left
cost < selling price
energy prices fall
probably the most important resource
new jobs in new areas
optimal blend since 1998
