Transcript of Hydraulic Fracturing

*additional holes to promote gas
What is our presentation about?
"fracking"
Hydraulic
Fracturing
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
Fracturing fluids
*ingredients:
slurry of water, sand, and chemical additives
disadvantages
contamination of drinking water
emissions
accidents during transport
acoustic emission
quake?
*partially already banned
German purity law
clean fracking
Experiments in Austria
inefficient and still wasteful
political situation
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

Environmental
Impact
air emission
water consumption
water contamination
radioactive contamination
health risks etc.

advantages
Air Emission
related to methane leaks
emissions from the diesel
reports of health
problems

Earthquakes
fracking = microearthquakes
several earthquakes
detected

Water Contamination
chemicals 80-300 t
radioactive material and heavy metals
50-80% of toxic waste fluids left

cost < selling price
energy prices fall
not dependent
probably the most important resource
new jobs in new areas
optimal blend since 1998
