Fracking Technology On Extraction Of Shale Gas And Oil Essay

Fracking technology. What are the environmental and health issues related to fracking technology on extraction of shale gas and oil? Unconventional gas and oil extraction process known as hydraulic fracturing, hydrofracking or fracking is a technique used to extract shale gas and oil, on which high pressure fluid is injected, mainly water, containing sand, chemicals or other granular materials which are pumped with a fluid medium under pressure into rock, so that fractures formed in this process are held open when the pressure is released, allowing oil or gas to flow more freely suspended, with the aid of thickening agents. Once that unconventional gas and oil extraction (fracking) has becoming widespread practice and a concern in some countries, particularly in the United States of America (USA), relatively about potential environmental risks and human health outcome, as well as potential routes of human vulnerability, has been the focus of several studies by social researchers, health and environmental scientists, and epidemiologists. This essay will present and analyse the challenges imposed by hydraulic fracturing to extract oil and shale gas, particularly related with environmental and health issues. Hydrofracking began in 1947 as an application in the USA and was followed in 1950 by the first commercially successful application. Although, only recently (in 2007 the method was first used by Petroleum engineers under North Dakota and Montana known as the Bakken toShow MoreRelatedThe Effects Of Fracking On Middle East And Other Countries For Oil And Gas903 Words   |  4 Pagesespecially oil, and this has been literally referred to as the motor of the world. In an effort to reduce dependence on Middle East and other countries for oil and gas, U.S has heavily invested in other forms of energy extraction from the core of the earth through a process that has come to be referred as fracking. Fracking is a short term that is used to refer to hydraulic fracturing. Hydraulic fracturing is a form of technology that is being used to unlock vast quantities of natural gas from shale bedsRead MoreThe Importance of a Secure Energy Supply for the Future826 Words   |  3 Pagesform or anther. Petroleum, coal and natural gas are the most produced and used energy sources. Mining technologies are required to obtain the raw materials of these energy sources from nature. The energy crisis is due to the limited amount of the natural storages of the energy resources. A higher production rate of the raw materials is desired so that more resources can be extracted to meet the demand. There have been conventional technologies for gas drilling for over 100 years. However the conventionalRead MoreFracking, The Splitting Decision : An Analysis1726 Words   |  7 PagesFracking, The Splitting Decision: An Analysis of the Advantages and Disadvantages of Fracking Abstract Fracking, or hydraulic fracturing, is the process of drilling into the Earth and subsequently directly a high-pressure water, sand, and chemical mixture at shale rock to release the gas inside, out through the head of the well. Fracking allows firms to access previously inaccessible resources of oil and gas buried underneath the earth and hidden in the rocks. In the U.S., fracking has boostedRead MoreFracking : A Reliable Energy Solution1386 Words   |  6 Pages Over the past decade oil and gas producers have increasingly used hydraulic fracturing also known as fracking to extract oil and gas from the earth. Most people believe fracking is a new process but it has been around for over 100 years. Modern day fracking began in the 1990’s when George P Mitchell created a new technique by combining fracking with horizontal drilling. Since then, U.S. oil and gas production has skyrocketed. But the â€Å"new† perception of fracking leads people to incorrectly believeRead MoreFracking And The Gas Industry1573 Words   |  7 Pageshydraulic fracturing - a process for extracting natural gas- has spread rapidly across the United States. High volume hydraulic fracturing, or â€Å"fracking,† is a process in which water and chemicals are injected into shale formations underground in order to release trapped natural gas. As fracking spreads throughout the United States, there are more and more reported cases of contaminated drinking water and illness among citizens living near fracking sites. Even with these cases, it is still difficultRead MoreShale Gas And Its Effects On Human Health Essay2163 Words   |  9 PagesDue to innovations in technologies and techniques involved with shale gas extraction, shale gas production in the United States, as well its natural gas production as a whole, as increased tremendously over the past several decades. As the abundance of domestic energy continues to grow, American consumers have observed declines in gas prices across the nation. However, cheap gas comes with a price: the negative impacts that cheap oil prices and shale gas extraction have on the U.S.’s environmentRead MoreThe Effects Of Fracking On Environmental Impacts On The Environment1094 Words   |  5 PagesSubstantial societal concerns regarding fracking s environmental impacts have been rai sed. Firstly, the water requirements are significant, with an average of 20 million litres used per well. This is 50-100 times more water than in conventional natural gas extraction. An increase in fracking may exacerbate current global water stress due to pollution, climate change and population growth (Kim 2014). In addition to this, the water mixtures used in fracking contain an average of 200 000 litres ofRead MoreThe Oil And Natural Gas Industries1686 Words   |  7 Pages Around the globe, the oil and natural gas industries are a major part of stable and growing economies, as well as, the individual lives of most people. As individuals we use it to run our vehicles, heat our homes, cook, and much more. Economies, on the other hand, rely on the oil and natural gas industries for the jobs they create, the product they supply, and the added value created by government revenues. In 2011, these industries in the United States made up 5.6 percent of the nation’s totalRead MoreThe Economic Report On Fracking, Is It Worth It?1465 Words   |  6 PagesEconomic Report Fracking, is it Worth it? Ron Withall Business 630, Dr. Lynn Reaser SUBJECT Our dependence on foreign oil and natural gas has created a vulnerability affecting our national security and economic stability. Up until this past decade there was an appreciable decline in our oil and natural gas production in the US and we were tied to world market price fluctuations. Oil prices and natural gas prices rose and fell based on OPEC’s and other large oil and natural gas producers’ productionRead MoreThe Issue Of Hydraulic Fracturing1444 Words   |  6 Pageswhere the health of future generations is set against our energy needs and economic growth, is the issue of hydraulic fracturing, or fracking as it is colloquially called. America’s new-found energy independence has been made possible using technology that was only a pipe dream a mere decade ago, slashing the disparity between net imports versus exports of crude oil and petroleum products, with exports skyrocketing more than 400% since 2006 and the advent of hydraulic fracturing (1).
