Fracking is a modern technique to explore natural gas through a controversial procedure. The controversy about scientific evidence for the impact of fracking has raged unabated for over a decade. It has now become one of the most popular debates between the supporters of Greenpeace or environmentalists and the energy companies. Now it’s a centrepiece of discussion in the context of the energy solution and considered as a really important source of energy by last few decades. Recent developments in the field of natural gas have led to a renewed interest in fracking. Energy seekers support a lot of arguments for their strength at the same on their counterparts. However, this essay will give a brief overview of the history, process, the benefits and the drawbacks of fracking within next few paragraphs below; Fracking is a stimulating process used by the energy company to initiate extra pressure in a producing formation to speed up the flow of gas more smoothly into the wellbore from the pocket of thousand feet deep underground rock. Moreover it can be used to remove natural obstacles to the flow of fluids by million gallons of water with various chemicals and sand with an ultimate pressure injection to the wellbore. Growth of microorganism can be protected by water and other additives like biocides. Fracture can be uncovered by the chemical gelatinous material and ball bearing which accepting the pressurise fluids to escape of again – along with the gas. Shanon (2011) said “Thousands of gallons gelatinous materials are pumped under extremely high pressure followed by jet turbines for the fracturing of rock formations.”

The first natural gas well drilled in the US by Devonian Shale in 1821.Than at 1860s, stimulator like Liquid solidified Nitro glycerine were used in shallow hard rock well in Pennsylvania. Later, horizontally drilled wells were first noticed in Texas in the 1930s. The technology has been endurably matured and developed; and in 1980s, it shows like a standard industry practice. Subsequently in 1990s, Barnett shale made it enabled to get the shape in economically viable for both horizontal drilling and hydraulic fracturing technologies. It seems that fracking has an enormous economic potentiality like accelerating the revenues, foreign investment, increasing national income, improving infrastructure, employment generation, safety reserve for future demand and much more. According to Shannon (20011), “There are huge possibilities, so, shale gas is chased by everybody.” It is North America, which already got a sufficient positive impact by natural gas through fracking. It could be creating a huge number of permanent and temporary jobs for residents and lead to gain energy independence. “It’s necessary to produce the gas with significant care, hope we will able to do it. It's necessary for us, both energy independence and contributes to job creation and growth will be achieved by it.” (Clinton, n.d). Obama(2012) spoke” we have a sufficient gas for America nearly one hundred years and there is a possibility to create more than 600.000 jobs by the end of the decades.” Fracking could be enhancing the tax revenue and national income of a country as well as economic enrichment. Mr. Moorman (2012) explicitly mentioned “Northern Ireland has a huge possibility of economic gain and of 14000 direct jobs by the year 2050 from £6 billion investments”.. In most recent studies suggested that fracking could be helpful for sustainable green environment as shale gas has low carbon content compared to other fossil fuels and acting as a bridge to reduce carbon in the future. It will result in a lot of foreign investment in the development of a country. For the purpose of a safe, secured, sustainable and economically viable technology, its design was incorporated by state of the art and sophisticated procedure to...
