Fracking is a process in which a drill is inserted into a shale, which is a cracked surface, usually rock or clay, under which oil is expected or estimated to lie. The drill then blasts the underground well with large amounts of a liquid, usually water with added chemicals for fluidity. The fracturing occurs within the ground and/or rock formation when the water pressure is applied and veins are created for oil to flow through freely. Whereas a typical oil rig can only pump for oil vertically, many companies that induce fracturing will drill vertically as well, creating more possibilities for the procurement of natural gas and oil. The first instance of the processes's use was in Barnett, TX, in the Barnett Shale, and has been going on for over 50 years with what some would say has been spotty government regulation, and which others would say has been too much or unwarranted in the instances in which it has occurred.

- With the age of constant industrial and technological growth has come the necessity for not only cost effective and efficient methods for industry, but also the need for obtaining fuel for the machines that make the modern world possible. Oil has become as precious a commodity as gold, if not more so; its attainments constantly driving the world's largest businesses and governments across the world into action. Naturally, a "quick-fix" solution to this problem is constantly sought after by oil companies wishing to provide oil on a massive scale.... [tags: hydraulic fracturing]

- Do you ever wonder how we have constant supplies of oil all around the world. Over the past couple of decades, oil companies have created an obscene amount of different methods for extracting oil, such as fracking. According to BBC News, fracking is defined as the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Water, sand, and chemicals are injected into the rock with high pressure which allows the gas to flow out to the head of the well.... [tags: Natural gas, Petroleum, Greenhouse gas]

- Ever since knowledge of fracking has entered the common domains, people have been bombarded with arguments for or against the process. Fracking is a process in which a drill is used to drill into the earth and extremely high-pressure water, combined with sand and chemicals, is used to force natural gas out of the ground to be used in any number of ways. The article being analyzed in this instance is firmly within the anti-fracking camp. Unfortunately, the article is also very much unreasonable mostly for the lack of evidence for its claims....

- ... However local governments can still be given the accountability of fracking by the general public and therefore fracking is said to disempower local communities (De Rijke 2013). Global Geopolitics of Fracking The success of hydraulic fracturing will have huge geopolitical implications around the world. As the production of shale gas increases, the global price to import fossil fuels will decrease. Countries will a dependence on the production of conventional oil and gas such as the Gulf monarchies and Russia will lose trade and income where as big importers such as China and India will have a lot to gain from an increase in hydraulic fracturing (Blackwill & O’sullivan 2014)....

- FRACKING Fracking is the method of extraction gas and oil that are under the Earth’s surface. Although many scientists say it’s a less harmful technique for the environment, there are several facts that show us that there are dangers that not only threaten the stability of nature, but also our own health. This method consists of introducing huge amounts of water, sand and dangerous chemicals into the earth in order to break the layer underground in order to pump out gas and oil. There are chemicals involved in this process, which causes contamination of the environment and the atmosphere.The hydraulic fracturing started several decades ago in the United States.The first enterprise that inves...

- Fracking or hydraulic fracturing is when some corporations extract gas and oil from rocks that lay deep underground. The United States of America have used the fracking method since the 1940s, but in recent years, it has become popular within investors to make a profit out of. Despite that the oil industry has become a higher demand now in today’s society for the demands of people. According to statistics around 60% of oil consumption is made possible by hydraulic fracking. Additionally, corporations such as Halliburton that drill a well that injects millions of gallons of toxic fracking fluids make the extraction of oil possible....

- Is harming the environment ever justified. What if there was a way to develop a natural resource but you harmed the environment in the process, would that be fine. As a matter of fact there is a new innovative way to acquire a natural resource, natural gas, but the process brings as many risks as benefits. Hydraulic fracturing, or fracking, is a process where shale rocks are fractured in order to release natural gas by puncturing and injecting fluid into the ground at high pressures. This procedure is very important because it provides us with abundances of natural gas, which is a fossil fuel that can provide many benefits to us especially now that we are lacking natural, alternative fossil...

- Have you ever been to Hell. No one is quite sure how far underground you have to go to get there or what you have to do to be sent there, but no one truly wants to go. Fracking might be putting people closer to Hell than the government thinks. What is fracking. “…hydraulic fracturing… as a means of extracting natural gas and oil from shale formations located deep underground (Davis and Fisk 1). Fracking has caused many ethical issues due to the many problems it has caused for the people who live around the fracking sites.... [tags: Water supply network, Water]

- Hydraulic fracturing is the propagation of fractures in a rock layer by a pressurized fluid. Fracking is one such highly dynamic source of getting natural gas.The technique is used to increase or restore the rate which fluids, such as oil, gas or water, can be produced from the formation. By creating or restoring fractures, the surface area of the formation exposed to the borehole is increased and the fracture provides a conductive path connecting the reservoir to the well, which effectively increases the rate that fluids can be produced from the reservoir formationsIt cannot be denied that people and governments need this resource in wake of technology changes....

- Overview of Environmental Concerns related to Oil and Gas Fracking As long as the world continues to need energy from fossil fuels, the oil and gas industry will develop new techniques for maximizing recovery of deposits in the ground. Fracturing, a relatively expensive new process for accessing major oil and gas formations across the US and other energy-producing nations, is at the center of an important ethical and environmental controversy. Hydraulic fracturing (“fracking”) and unconventional shale gas recovery are processes for speeding up the production and harvesting of natural gas and/or oil in underground formations....
