Hydraulic fracturing or fracking was developed around the 50’s in America but techniques used today are more recent due to advancement in technology. The process made extracting gas and oil trapped deep in underground a more viable option. Instead of trying to drill individual pockets of gas fracking uses liquid pressure. Directional drilling is used alongside hydraulic fracking to extract the resources. Once the drill reaches a layer of shale, the EPA states that a mixture of water, proppant, and chemical additives to use for liquid pressure. Once the shale is fractured the trapped gases come together and flows back, along with the mixture, through a wellbore. (EPA 2017) This technique allows companies to tap into reserves providing cheaper natural gas and oil. Companies are able to provide jobs for many people and reliance on imported …show more content…
A reported study from Stanford writer Mark Golden, states that though previous conventional drilling techniques use less water initially in mining natural gas. Fracking would use less water if not utilizing electricity from coal. Replacing coal as a way to power machinery with natural gas or nuclear power would effectively cut water consumption.(Golden 2014) The waste water that comes from the rigs also pose a threat to the environment. The waste water is often injected underground where it has been known to trigger seismic activity in the dig site and surrounding areas. The injection of the waste water causes stress and ruptures in faults deep underground. Waste water seeping upwards into aquifers is deemed as rare cases due to the techniques used by companies. Though the use of waste water for livestock and forestry creates problems due to the run offs entering aquifers. Certain loopholes in the Safe Drinking Water Act mean the EPA do not regulate fracking fluids so harmful chemicals are present in the waste waters. (Cho

Pros And Cons Of Fracking

Fracking: Pro and Con Hydraulic fracturing, often referred to as “fracking,” is method of extracting natural gas from shale deposits several thousand feet underground. Although it’s led to a natural gas boom in the U.S. that’s resulted in cheap energy, fracking has been the cause of much controversy. Proponents of fracking like Bruce McKenzie Everett, an international business professor, cite how much Americans have benefitted from the explosive growth of the fracking industry. It’s dropped energy…

The Pros And Cons Of Fracking

Fracking, is an innovative and cost-saving process for drilling oil and gas from rock formations far underground. It is a strong and controversial topic with opinions that stem from both the pros and cons. To begin with the cons in Source A, it states, “ The fracking cocktail includes acids, detergents and poisons that are not regulated by federal laws but can be problematic if they seep into drinking water.” This goes to show that even with the advancements we have made to extract natural gas and…

The Pros And Cons Of Fracking

Fracking is when you are drilling down into the earth before a high-pressure water blend is aimed at the rock to release the gas inside. Water, sand and chemicals are infused into the rock at high pressure which allows the gas to stream out to the head of the well. The procedure is most commonly done by drilling the stone layer which can make new pathways to release gas but it can also be used to develop existing channels. The term fracking shows how the rock is fractured apart by the high pressure…

Hydraulic Fracking Pros And Cons

The developing evidence has begun to stir conflict between industry representatives and environmental groups and U.S. citizens. Industry representatives claim that hydraulic fracking is precise, safe and an environmental friendly alternative because it lessens dependency on coal and oil energy. Spokesperson for the Marcellus Shale Coalition, a business lobbying group, Travis Windle stated, “The technology rivals NASA” with its precision (McGlynn 1051). Hydraulic fracturing is also toted at as sustainable…

Fracking is a method for harvesting fossil fuel that is for almost six decades. Although, it has its pros, it only lasts for a short period of time. In contrast, the downside of fracking has a high chance of lasting for a lifetime. It is evident that the negative affect will harm us in many ways such as food poisoning. Fracking is a energy harvesting method that must be illegalized so it won’t contribute to any problems we face today. Hydraulic fracturing, or fracking is a dangerous method that…
