2. 1.What is fracking?
Fracking is a common term to refer to the technique of
hydraulic fracturing for the extraction of unconventional gas.
Involves the extraction of natural gas by the fracturing of the
rock mother (slates and schists). A mixed drilling technique is
used to extract the gas trapped in the rock: first drilling up to
5000 meters vertically and then punched several kilometers in
horizontal (2-5). Then inject water with sand (98%) and a series
of chemical additives (2%) to great pressure. This makes that
you crack the rock and gas is released and ascends to the
surface through the well. The process is repeated through the
grain of rock rich in gas. Some of the injected mixture returns
to the surface.
3. 1.Tanker trucks deliver water, wich is mixed with sand and chemicals
before it’s being pumped into the well.
2.The energy from the highly pressurized fluid creates new channels in the
rocks to release the trapped natural gas.
3.Natural gas flows out of the well and into storage tanks. The recovered
water is stored into open pits and then delivered into treatment facilities.
4.Stored gas from the site is sent to the markets via networks of pipes.
Hydraulic fracturing is literally to crush rocks with sand and loads of harmful chemicals
in order to bring gas to the surface.
2. Problems with fracking
Over 600 of the chemicals wich are used for doing fracking
fluid are cancerigenous such as: uranium, formaldehyde,
methane, radon, mercury…
During this process, methane gas and toxic chemicals
leach out from the system and contaminate nearby
groundwater.
Methane concentrations are 17x higher in drinking-
water wells near fracturing sites than in normal wells.
There have been over 1000 documented cases of water
contamination next to areas of gas drilling as well as
cases of sensory,respiratory and neurological
damage due to ingested contaminated water.
Only 30-50% of the fracturing fluid is recovered, the rest
of the toxic fluid is left in the ground and is not
biodegradable.
In the end, hydraulic fracking produces aprox. 300.000
barrels of natural gas a day, but the price of numerous
environmental , safety and healthcare hazards.
And also release volatile gas to the atmosphere creating
contaminated air, acid rain, and ground level ozone.
And also a huge amount of water is spent on fracking.
The pipes and barrers could fail, or rain could do the
tanks to flood so its easy for contaminated water to
filter to the environment.
• Contamination of groundwater
• Methane pollution and its impact on climate change
• Air pollution impacts
• Exposure to toxic chemicals
4. • Blowouts due to gas explosion
• Waste disposal
• Large volume water use in water-deficient regions
• Fracking-induced earthquakes
• Workplace safety
• Infrastructure degradation
The paper compiled a list of 632 chemicals (an
incomplete list due to trade secrecy exemptions)
identified from drilling operations throughout the
U.S. Their research found that 75% of the
chemicals could affect the skin, eyes,and other
sensory organs, and the respiratory and
gastrointestinal systems. Approximately 40–50%
could affect the brain/nervous system, immune
and cardiovascular systems, and the kidneys; 37%
could affect the endocrine system; and 25% could
cause cancer and mutations.
5. Fracking Is not good for nature because of all
contaminating chemical substances.
4. Solution
There is no clear solutions to fracking because green
fracking is more expensive but less contaminating than
normal cheap fracking. Green fracking would cost
about 25% more.
