demand and is only expected to grow. Shale gas is natural gas that is found trapped in shale. Shale is sedimentary rocks that consist of clay minerals that have low permeability. Natural gas that is found in shale is buried in fractures below ground and must be extracted by hydraulic fracturing, also known as fracking [10]. One of the most recognized sites for the extraction of natural gas by fracking has been at the Barnett shale in the last decade. The Barnett shale is a region that extends west of
Chapter 1 Research purpose and meaning 1.1 Concept Shale gas is a kind of unconventional nature gas, which is trapped or gathered in the dark shale or carbon rock. The rock layer has low permeability and low porosity, which means that the best way to get this recourse is fracturing to enhance connectivity and porosity. The shale gas reservoirs are mainly located in North America, Central Asia, China, Latin America, Middle East, North Africa and Russia and other countries and regions. The United State
With its abundance of genera, the Burgess Shale is one of the world’s most important fossil fields. It’s discovery in 1909 led to over 100 years of paleontological study in the Canadian Rockies, a majority of which has been carried out in two quarries known as the Walcott and Raymond quarries (Hagadorn, 2002). Though he was originally in search of trilobites in the Burgess Shale Formation, paleontologist Charles Walcott also discovered a diverse group of soft- and hard-bodied fossils, from algae

It is a known fact Pennsylvania is greatly impacted by the Marcellus Shale. The Marcellus Shale is a layer of black shale located under the Appalachian basin from Prehistoric times. Natural gas and oil are being extracted from this layer for their increasing economic value, with natural gas having a worth of $10 for every thousand cubic feet of it. Furthermore, improved technology such as “hydraulic fracturing” and “horizontal wells” has made Marcellus drilling more efficient and has increased the
actually distinguish, ‘What IS the Burgess Shale?’ Well, it is said to be a “shrouded legend” deep in the Canadian Rockies discovered in the early 1900s by Charles D. Walcott, notorious Smithsonian Secretary (Adler 2013). According to Haug, Caron, and Haug in their research article ‘Demecology in the Cambrian: Synchronized Molting in Arthropods from the Burgess Shale’ the Burgess is “arguably the best-known Konservat-Lagerstätte”. While the Burgess Shale is primarily known for the intricate preservation
features in Glacier National Park is the color banding. This feature can be seen in nearly every mountain within the park as they are composed of different layers of rocks and colors. The rock strata are mainly composed of sedimentary rocks limestones, shales, sandstones, and lightly metamorphosed rocks (Dyson,1957). These rocks all belong to a single large unit known as the Belt series. The rocks are very unusual in that they were deposited in late in the Precambrian between 1600 and 800 million years

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. “…, it has become increasingly controversial because of rising
I. Introduction-The Grand Canyon The river has cut through the earth, which allows us to see the passing of eons before our eyes. The Grand Canyon is an impressive one mile deep canyon with red, grey, white, brown, and black rock formations, cliffs, and slopes. The Grand Canyon runs along the Colorado River from Marble Canyon, near the Utah-Arizona border, to Grand Wash Cliffs in Mojave County, Arizona. It is considered to be one of the seven wonders in the natural world. The Grand Canyon became
Additionally, the principle of original horizontality establishes that when rock layers are flat, they have not been disturbed and therefore are in their original horizontal sequence. Using the Grand Canyon as an example, scientists recognize that layers still have their original horizontality because they have not been folded and thus they have not experienced significant crustal disturbances. Furthermore, relative dating uses the principle of cross-cutting relationships which states that features
than conventional resources due to presence of additional, more sophisticated processes such as hydraulic fracturing and steam assisted gravity drainage. An example of an unconventional resource would be shale rock, which contains shale oil and shale gas. Unlike regular sedimentary rocks, shale rock requires a combination of hydraulic fracturing and horizontal drilling in order to be commercially viable for further marketing purposes. Unsurprisingly, unconventional hydrocarbon recovery poses much
Marcellus Shale drilling causes a problem because it involves the use of hundreds of deadly chemicals. Over three hundred chemicals are used in the Marcellus Shale drilling process (Environmental). According to Howells, author of the article “Don’t Frack with Our Water!,” these chemicals are especially dangerous because the companies that use them will not tell the public what specific chemicals are being used. However, through studies of the chemicals, some of them can be identified. Some of the

I discussed my interests with Dr. John Doe, who has also obliged to serve as my supervisor should I be admitted into the doctorate program. The role of shale oil, shale gas, tight oil and tight gas reservoirs, generally classified as unconventional reservoirs, in meeting with the ever-increasing energy demand has come under serious considerations in recent times. While significant successes have been achieved
Pierre Shale Introduction: Millions of years ago, the earth had a different geographical look and the seas covered vast quantities of land that can now be seen. Many present day coastlines were completely submerged and the waters invaded deep into continents making vast portions of the landmasses an aquatic environment. These aquatic environments supported many different types of living creatures, from large mammals all the way down to plankton, algae, and microscopic organisms like bacteria and
The notion of sustainability sometimes seems vague when applies to real world decision making process. But one universal agreement with regard to how sustainability functions in the political and economic arena unfolds as decisions made today would have huge impact on both nowadays and the future. According to Goulder and Stavins, economists, in order to help decision makers implement policy evaluations, would commonly discount future impacts. Basically, discounting serves as a mechanism to convert
and their difficulty spoke volumes about the risks involved in fracking. According to the DRBC website, ?In connection with natural gas drilling, the commission has identified three major areas of concern: 1. Gas drilling projects in the Marcellus Shale or other formations may have a substantial effect on the water resources of the basin by reducing the flow in streams and/or aquifers used to supply the significant amounts of fresh water needed in the natural gas mining process. 2.On-site drilling
Hydraulic Fracturing and Directional Drilling have allowed the production of oil and gas from “unconventional” resources, like shale gas and shale oil. Natural gas demand is increasing, in addition, is increasingly becoming an important role in meeting demand for energy in the United States. Thus Hydraulic Fracturing stimulated shale among the fastest emergent energy sources in the United States, a source that seemed impossible to few years ago. Natural gas, the cleanest burning fossil fuel, now
when you type in “evolution”. In stark contrast to this idea of evolution, Stephen J Gould presents a less restricted idea of evolution. He left some of the decision up to chance and showed this theory by discussing it within the Cambrian Burgess Shale. More specifically, there are two main themes represented in this book by Stephen J Gould: showing evolution as a ladder or cone, and if it were possible to “replay the tape of evolution” the results would be considerably different and specifically
Introduction “Hydraulic fracturing involves the use of water pressure to create fractures in rock that allow the oil and natural gas it contains to escape and flow out of a well (Energy From Shale).” Fracking has served to extract natural gas and oil where other methods would not be as successful but many environmentalists argue that fracking is affecting the environment and our drinking supply of water. Although fracking is still a controversial topic, it provides Americans jobs, increases the economy
