The main objective of the process of hydraulic fracturing is to access oil and gas resources that are locked in non-porous rock (Howarth, Ingraffea, and Engelder 3). The main type of rock surface that is used in this process is shale rock due to its vast amounts of trapped natural gas mostly consisting of methane (1). When hydraulic fracturing occurs, a well is drilled horizontally into the shale rock surface at about 1000 meters deep (Kramer 2). The next step in the process is to create channels for the gas trapped in the rock to escape through. This is done by injecting a substance known as fracking fluid deep inside the well at consistently high pressure, causing the rock to fracture. Once the channels are made, pressure is released and the fracking fluid flows back up to the surface supposedly into a confined disposal area.
This newly developed technology has strong supporters for three main reasons. First pro-fracking companies stress the fact that the United States has an abundance of natural gas just waiting to be extracted for our use. Secondly it is thought that the energy obtained from shale gas is more efficient and economically feasible th...

- In today's global economy, energy is one of the most crucial and sought after commodities. Who supplies it and how much they supply determines how much influence they have over other countries as well as the global economy. This is why hydraulic fracturing is currently such an important and controversial topic in the United States. Hydraulic fracturing, more commonly known as "fracking" or hydrofracturing, is the process of using pressurized liquids to fracture rocks and release hydrocarbons such as shale gas, which burns more efficiently than coal....

- If the question: “what hydraulic fracturing or fracking is?” was asked to the average person, depending on their location their answer could vary. Most likely though most or many people would not know what Fracking truly is but most would say that they have heard at least a little about it from the news. Hydraulic fracturing also known as fracking is a process that occurs after well has been drilled or bored, and the process through use of a perforated casing that injects fracking fluid which travels through the holes and to target zones and soon when the target zones can’t absorb the fluid and pressure is created causing natural gas or oil to flow up to the surface (Hydraulic Fracturing 101...

- In recent years there has been great concern over the growing demand for energy, and the lack of non-renewable energy resources to meet the demand in the future. In addition, the question of “sustainability”—the ability to balance social, economic, and environmental needs in energy production to meet both current and long-term requirements—has come to the fore. It is clear that America must expand energy production quickly, and that we must develop renewable, sustainable energy sources to meet long-term demand and protect our future....

- One of life’s truly rarest treasures is human unselfish charity. The greatest thing in the world is mutual understanding and the endless feeling of appreciation of having a Home. A place that every one of us has to have: where a happy, loving family could be born, where love, support and acceptance, no matter what, always are, and where kindness, warmness, understanding are sincere and never go away. I think those of us who have homes have to count ourselves exceedingly fortunate, because we are blessed.... [tags: Are the Homeless Crazy?, 2015]

- An individual’s environment plays a pivotal role in their overall health. The environment can affect a range of physical and mental processes, and is considered a defining factor of well-being. As a result, specific geographic areas are instrumental in shaping an individual’s health profile. This is clearly seen in the disparity between those living in areas exposed to toxic substances, versus individuals living in clean environments. Individuals in unpolluted environments experience the advantage of a body system free from the barrage of chemical assault.... [tags: hydraulic fracking research paper]

- Hydraulic Fracturing is the cracking of the Marcellus Shale by injecting more than one million gallons of water, sand, and other chemicals at a high pressure into wells that go as far as 10,000 ft. deep. Miners and people who work for gas companies do this to collect the natural gas that shale rock produces. “Fracking” was developed by Haliburton about 60 years ago. This was a big break through because there was a point in time where the United States was considered energy poor. With this relatively new finding, the U.S.... [tags: fracking, energy, natural gas]

- Introduction Shale gas is a natural gas that is found deep in the earth’s crust. This type of natural gas usually forms in shale deposits and can be released with a drilling technique known as fracking. Shale gas has become the most important source of natural gas in the United States. Scientist and researchers have always known of shale gas, but none have had the technologies to reach it till now. In early 2000, shale gas compensated for one percent of the United States supply of natural gas resources, but by 2010, shale gas accounted for over twenty percent of the United States supply of natural gas....

- Hydraulic fracturing, also known as fracking, is a method of extracting natural gas from underground by drilling and pumping large amounts of water beneath the Earth to open up natural gas deposits (Banerjee). Countries with large natural gas deposits, such as France and Bulgaria, have already banned the practice of hydraulic fracturing. Though fracking may seem like a new concept, it is not; about one million wells have been fracked since the mid-1900s in America (Brantley). Fracking has only become so controversial recently because the most current proposals have been in more residential areas.... [tags: hydraulic fracturing, natural gas extraction]

- Crazy Horse The European settlement of North America met its fiercest opponent, the Lakota also known as the Western Sioux, who inhabited most of the Great Plains. The Oglala tribe, a branch of the Sioux nation were key in the resistance against the white man. At the heart of their resistance stood crazy horse, a warrior that had no equal. Crazy Horse fought for the traditions of his people, until those same people wearied of war and in some cases, turned against him. Chief Crazy Horse led an extraordinary life and will always be remembered.... [tags: Biography Biographies Bio]

- When I think back of the stories that I have heard about how the Native American Indians were driven from their land and forced to live on the reservations one particular event comes to my mind. That event is the Battle of the Little Big Horn. It is one of the few times that the Oglala Sioux made history with them being the ones who left the battlefield as winners. When stories are told, or when the media dares to tamper with history, it is usually the American Indians who are looked upon as the bad guys.... [tags: Battle of the Little Big Horn]
