    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

    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

    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

    as an intracratonic basin (Bois and Pelet 1982). The Illinois Basin began as a rift complex which eventually failed, the New Madrid fault is associated with this rifting (Hasenmueller and Comer 1994). The depositional thickness of the New Albany Shale was strongly affected by the regional down-warping in southeastern Illinois (Lineback 1980). The Illinois basin is separated from the Michigan basin by the Kankakee arch, which is located primarily in Indiana (Nelson 1995). To the South East lies the

    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
