Historically, there are three main means of extracting natural gas: vertical drilling, horizontal or directional drilling, and hydraulic fracturing, each playing a role in both oil and natural gas development throughout history. Vertical drilling is typically used to access reserves that are in more porous reservoir rock. Vertical drilling is the extraction technique used to retrieve natural gas from a highly permeable formation that will allow the gas to flow toward the end of the wellbore. This method only extracts gas from the portion of the well that intersects with the reservoir rock. Vertical drilling is a traditional method for easily accessible natural gas reserves.
Horizontal drilling and fracturing have also been used to extract conventional oil reserves, however with advances in technology this technique has been fine tuned to extract unconventional sources that are trapped in shale formations (Ratner and Tiemann, 2014). Horizontal drilling allows for gas extraction from less permeable rock formations. Horizontal drilling allows the wellbore to follow a formation for a significant distance and a much larger portion than a vertical well could. Horizontal wells also allow for as many as 9 or more wells to be drilled from a single well pad. Although, horizontal wells are more cost intensive and time consuming generally there is an increased amount of production and more natural gas can be extracted.
Hydraulic Fracturing is not a new extraction method; technology has simply developed to allow fracking to become a viable option when extracting unconventional oil and gas. The process by which fracking releases gas trapped in its shale formation is multi step and requires precision and timing. Ultimately, th...

intensity of violent ethnic conflict has likely to be reduced since the signing of peace accord in 1997. However, the people in CHT are dealing with new dynamics of conflict which has caused less violent but protracted social tensions and conflicts. Natural resource conflict is becoming paramount dynamic of social conflict in CHT region. The CHT region is the only extensive hill area in Bangladesh. The region consists of 3 districts which are located in southeastern part of Bangladesh. The population
Introduction: Environmental and socioeconomic debate over an alternative method of extracting natural gas thousands of feet below the surface using horizontal drilling and hydraulic “fracking” has risen in last twenty years. Fracking is the technique of drilling deep wells under high pressure with sand, water and a variety of chemicals to crack open rocks to release natural gas (hydrogen carbons) and oil from shale or coal bed methane deposits. Townships in Colorado like Lafayette and Fort Collins
into the ground at high pressure in order to crack shale rocks and release trapped natural gas from the ground. Fracking was first used in 1947, at the Hugoton field in southwestern Kansas. Stanolind Oil (AMOCO) was the company that conducted the experimental fracking method. Floyd Farris, who works for AMOCO, is the person who preformed studies of the pressure of injecting water and certain chemicals into oil and gas wells; the process of fracking was introduced. Fracking can produce a lot of energy
The United States as well as the rest of the world are dealing with the issue that the world supply of oil is dwindling. Ever since our peak consumption year in 2005 the United States has been a major consumer of crude oil and petroleum products. As of 2012 according to the U.S Energy Information Administration “The United States consumed 18.6 million barrels per day of petroleum products, making us the world’s largest petroleum consumer.” The U.S. has long been dependent on foreign petroleum products
Pennsylvania Andrew Turner University of Maryland University College ? Different Attitudes Towards Fracking in New York State and Pennsylvania The United States has become one of the leading producers of natural gas in the world, and now is an exporter of natural gas as well. As natural gas imports increase, the U.S. Energy Information Administration, ?Expects the United States to
Hydraulic Fracking, the method of getting natural gas from the ground, has caused a number of negative affects on not only people but the earth. Numerous amounts of health problems are being noticed, air pollution is rising and the waste being dumped has caused issues for people in the area. Many people don’t quite understand what Hydraulic Fracking is doing to us and it is an issue that needs to be recognized.. The air pollution from the gas that is leaked during the process of drilling
fracking. Hydraulic fracturing is a process in which people drill into the earth, and then, at high pressure, a water mixture is sent down to release the natural gas from the shales. This process essentially fractures the rock the release natural gas. The reason for all the arguments is that businessmen want the money and value that natural gas has for energy, while environmentalists point out that the process hurts both people and the environment. Fracking should be regulated to the extent so

The main positive aspect is that, when burned, natural gas gives off lower emissions to our environment oil. In the future, due to its great abundance
including propane, natural gas, gasoline and coal. The government of British Columbia estimates it could reduce emissions by up to 3million tons annually and by 33 percent of greenhouse gas emissions by 2020. A strong and predictable price on carbon will lead to effective environment and provide new fiscal revenues. First, the carbon tax has a great effect on emission reductions for the purpose. It is considered as the most economically efficient way to tackle the greenhouse gas market failure. 6
control. Whereas when artificial light, generated by gas, is present the sentiments shown are those contrary to the urges of nature and more in accordance with the dictates of society at the time. Many of the main events that occur within the two houses reflect the difference between simulated emotions and artificial light, and true light and heart-felt sentiments. Within Thrushcross Grange, a symbol of success in the society of the day, the magnificent gas candelabra bathes the house in man-made light
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. The
The energy producing market has always been a staple in Pennsylvania's history. Being rich in coal, natural gas, and other forms of energy, Pennsylvania has produced much of the nation's fuel or electricity. With a location so rich in coal, companies began to open many mines in order to either stay ahead of competitors, improve production, or for easier transportation of the commodity. The large amounts of coal being mined ushered in the many railroad systems bringing another powerful business to
the future. The monitoring of temperatures in the Arctic have demonstrated that, over roughly the past 50 years, there has been a warming of about 2 to 3°C as of 2009. The average temperature in the arctic has increased almost twice as fast than the rest of the world. In 2020, the projected increase is up to 4°C as well as 8°C by 2050. A numbers of studies have shown that, based on previous climate records, there has been issues of rising sea levels, alterations in sea-ice dynamics, and permafrost
in the garden. The speaker in turn tries to remove the woodchucks by using humane gas to kill them and when that is unsuccessful, she resorts to more violent means. This poem uses the annoying woodchucks to signify the Jewish people during the Holocaust by the Nazi Party. In the first stanza of the poem, the speaker clearly identifies that some woodchucks are annoying her. To solve this problem, the speaker uses gas as a way to eliminate the pests quickly and painlessly much like the Nazis tried to
