Hydraulic Fracturing

Abstract: The oil and gas industry has been using hydraulic fracturing (also known as hydrofracturing and fracking) a way to boost hydrocarbon production since1947. Recent advances in fracturing technologies are responsible for the latest hydrocarbon production boom in the U.S. The process of hydro fracturing is where fluids are pumped at high pressure underground to fracture a formation and release trapped oil and gas. This paper reviews the process of hydraulic fracturing, the environmental and economic effects of hydraulic fracturing, and the different characteristics that come along with this process.

Paragraph 1: Introduction: In today’s world sources of energy are becoming increasingly scarce. Many experts believe that hydraulic fracturing or “fracking” is an alternative that will create a clean source of energy for the future. The U.S. has a vast amount of natural gas reserved that is viable as a result of advances in horizontal drilling and hydraulic fracturing technologies enabling greater access to gas in “shale formations”. Paragraph 2: What is Hydraulic Fracturing? : Hydraulic fracturing is the process of drilling and injecting fluid into the ground at a high pressure in order to fracture shale rocks and release natural gas inside and extract oils. During the process of the natural gas wells being drilled, millions of gallons of water, sand and chemicals are pumped underground to ensure that the rock is broken and the gas is released. After a well has been drilled, and a steel pipe has been inserted in the well bore, the fracturing process begins. This process usually occurs within the target zones that contain oil or gas, so that when the fracturing fluid is injected into the well it flows through the perforations (and aperture passing through or into something) into the target zones. At this point, the amount of pressure causes the formation to crack or fracture. Once the fractures have been created, injection stops and the fluids begin to flow back towards the surface. Fracturing fluids that returns to the surface are referred to as “flow back” and these wastes are typically stored in open pits or tanks at the well site prior to disposal. Paragraph 3. What is Hydraulic Fracturing Used For? : Hydraulic fracturing enables the extraction of natural gas and oil from rock formation deep below the Earth’s surface. The main industrial use of fracking is in stimulating production from oil and gas wells, but it is also applied to disposing waste by injecting into rocks, to measure stress in the Earth and it is used as a means of enhancing waste remediation, usually hydrocarbon waste or spills. This technique is used in a number of countries, including the U.S., Australia, and South Africa. Paragraph 4. Economic Effects: Depending on the geological characteristics of the formation, specific technologies such as hydraulic fracturing are required because certain resources have lower permeability than conventional gas formation. Hydraulic fracturing is known as one of the key methods to make extraction economically viable. Sources say that as a result, the U.S.

In order to understand how controversial hydraulic fracturing is, the importance of how this technology is socially constructed among the relevant social groups constructivist approach is relevant in understanding how knowledge and debates are formulated by differing social groups. Using this theoretical framework provides us with a background on how a technology, in this case hydraulic fracturing, is constructed through separate discourses. According to Bijker, “In the…

Pros And Cons Of Hydraulic Fracturing

Did you know hydraulic fracturing may be polluting drinking water? Hydraulic fracturing is not good because it can be harmful, to the health of people and the environment. The new technology is used to get natural gas from deep underground. Hydraulic fracturing does this by injecting water mixed with chemicals and sand into a type of rock. Then the cracks in the rock release natural gas that can then be collect. Yet, in the process, hydraulic fracturing is polluting drinking water and is badly impacting…

Ch 1 - No name yet Hydraulic fracturing is a process used after a hole is drilled in the surface that extends up to 10,000 ft in depth and 1 mile in width. Once the hole is drilled, fluids are inserted into the well which create small fractures on the walls of the well. Using pressurized fluids pumped into the wells, the fractures expand due to pressure and spread 1000 ft to 2000 ft. The fractures on the wells are kept open by "proppants", which are solid particles with the mixture of fluids inserted…

What the frack is Hydraulic Fracturing and why has it been such a controversial topic for the past several years? Hydraulic Fracturing, better known as fracking, “involves the injection of more than a million gallons of water, sand and chemicals at high pressure down and across into horizontally drilled wells as far as 100,000 feet below the surface” (Granberg). The rock layer is then cracked due to the pressurized mixture. These openings, by the help of sand particles, are exposed in order for…

Hydraulic Fracturing Who wouldn’t want cheaper gasoline or cheaper oil to heat their houses? The opportunity for cheaper fuel is definitely an option but at what cost to our health and to the environment. The process for getting this cheaper fuel is called “Hydraulic Fracturing” or “Fracking”. There are two main views, one it provides fuel at a cheaper cost and the second opinion is that it is harmful to the environment and we shouldn’t continue fracking. The United States should continue…

Hydraulic fracturing Impact and Analysis The modern day definition of hydraulic fracturing, or fracking, is the forcing open of fissures in subterranean rocks by introduction of liquid/solid mixtures at high pressure in order to extract oil or natural gas from the rock formation or shale. Typically the liquid that is used in fracking is a mixture of water, sand, and other various chemicals that could be hazardous.
