Pros And Cons Of Shale Gas
Shale gas: Pro and Cons for UK
Abstract
Introduction
Shale gas is natural gas that is found in shale formations. It is becoming increasingly important as major nations are beginning to become involved in this revolution. The gas is rich in petroleum and natural gas. Unlike conventional natural gas, which is in permeable rocks like sandstone, gas cannot flow through the shale. Therefore, just drilling a well isn’t enough to extract this gas. As a result of this, fracking or hydraulic fracturing is used.
Shale gas production
Fracking is a process that uses millions of gallons of water, sand and chemical that is pumped into the ground to break and fracture the rock and release gas [1]. The solution that is pumped is highly pressurized and therefore …show more content…
Just in the UK alone, the shale gas industry had created 74,000 jobs [4]. This clearly increases the employment rate in the nation which is beneficial for it and increases the economy. As there are more working in the shale gas industry, it will increase the amount of shale gas extracted and manufactured considerably. Due to the fact of more shale gas being manufactured the prices of energy can be decreased. Therefore, oil and fuel will be sold cheaper than the prices now. This would definitely attract new customers and increase the income of a company. Furthermore, this will increase and improve energy security so the use of oil and fuel will become much safer and it will ensure less wasted oil through a considerably long period of time. This can be until shale gas has run out which is approximately 90 – 100 years or until renewable energy is has developed to be reliable and work without fail. This has been predicted to take 30 – 50 years. The Shale Gas industry has also improved the balance of trading between countries. For example, minor or developing nations that require gas can begin (or carry on) trading with the UK as they can produce Shale gas for commercial reasons as well as national consumption. Because of this, relationships with other nations grow and more support such as military support is given when …show more content…
The ground water can again be contaminated from a leakage from the wellbore. Waste water is produced in shale gas operation during the flow back phase [6]. This can be a waste of water unless recycled. During fracking, when this flow back occurs, the liquid will pick up a variety of elements additional to the chemicals initially inside. On top of that, when the water goes down, tiny explosives are set off to release the gas. When exploded, fractures are created in the rocks that allow the shale gas to pass through. Surprisingly, these mini explosions can cause very small and localized seismic events. Regardless of the size, it has provoked the attention of a few
