Hydraulic fracturing or fracking, represents one and the same extraction process that injects a high pressure fluid into shale beds to release the oil and natural gas resources located in the underground rock. How fracking actually works A shaft is drilled deep into the earth at a depth of several hundred meters and from there a horizontal hole is drilled into the rock or group of rocks containing the natural gas layer.
This is done by injecting fluid into cracks to force them to open further, making it easier to extract oil and gas. It has been around since the late s when petroleum engineers were looking for other ways to increase well productions.
It turned out to be very effective considering that there are more thanactive natural gas wells in the U. But with oil prices plummeting, continued fracking can shake the oil and gas industry and the entire economy.
Too much supply with very low demand is clearly an imbalance that can have an adverse effect on everyone involved. What is surprising, however, is that bans on fracking are being lifted in various Pros of hydraulic fracking in the Americas.
Just recently, Republican governor in Oklahoma, Mary Fallin, has just signed into law a bill that prohibits a ban on fracking in towns and cities in Oklahoma. This enabled the Oklahoma Corporation Commission to retain control over oil and gas drilling.
So now, localities are prohibited from debating or deciding whether or not oil and gas operations will be permitted within their jurisdiction.
If fracking was previously banned and remains prohibited in other areas, there must be something wrong with the process. From an environmental standpoint, it is definitely damaging, considering that shale rocks are forcibly cracked to extract oil and gas.
Even if the product is natural gas, there are risks and dangers involved. List of Pros of Fracking 1. Access to Alternative Source of Fuel. The overwhelming supply of oil and gas may seem a negative aspect today, but there will come a time when these resources become scarce again.
Through fracking whatever shortage the world will experience will be resolved. Continuous study into the effects of hydraulic fracturing will also lead to more innovative and safer ideas of extracting natural gas. When both traditional oil drilling and fracturing work hand in hand, fuel shortage could be completely avoided.
Since the need for oil is likely to rise as population increases, it pays to have an alternative and domestic source in mind.
Time will come when daily oil exports across America will be lessened. Fracking basically uses huge amounts of water, sand and chemicals that are blasted deep into underground rock formations to crack them open.
With the chemicals injected deep under the earth, they would cause lesser to no damage, as opposed to when they are released on the surface or in the air. They are less likely to pollute bodies of water, ensuring that humans stay safe and healthy.
Chemicals out of the way also mean improved air quality. Whatever toxins that would normally have been released into the air would no longer pose a threat.
Moreover, when natural gas is used to generate electricity, there would be less dependency on coal and nuclear power plants. This can result in reduced carbon dioxide emissions that will also lead to a decrease in air pollution.
With oil and gas produced locally, industries that greatly rely on these fuel resources can become more competitive due to lower energy cost. This is why many believed that fracking has positively transformed the energy situation in the U. This can also result in lower taxes, especially when exporting oil is minimized.
Inthe oil and gas industry in America employed more than 1. The figures will soon double or triple considering that bans on fracking are now being lifted.
Until renewable energy is fully developed and made accessible to everyone, fracking will buy the world some time to turn such a plan into a reality.
List of Cons of Fracking 1. Requires Huge Amounts of Water. Each fracturing job would require 1 to 8 million gallons of water to complete.10 Chief Pros and Cons of Hydraulic Fracturing. List of Pros and Cons; Jul 8, There is an issue these days that surrounds a recent method of extracting oil and gas, which involves drilling deep down of the crust of the Earth.
The term is referred to as hydraulic fracturing. Accordingly, this method will extract deposits of oil and shale.
