and mechanical winning of coal rocks (Jin et al.‚ 2014). Brittleness is one of the significant rock parameters in shale reservoirs. It recognizes as key information to evaluate the capability of formation to create an effective fracture network that conducts the hydrocarbons to each borehole. Thus differentiating brittle from ductile rocks has been the key to unique success in shale gas reservoirs. In the lab scale‚ The Brittle failure is occurred when the ability of the rock to resist load decreases

Economics Final Paper The Impact of US Shale Gas Exploration on the global LNG tanker market Abstract The triggers for this study have been several articles prophesying a shale gas revolution in the LNG tanker business. Following that‚ the author seeks to assess the real prospects that can be drawn from US shale gas exploration and whether their impact is long- or short-lived. The LNG tanker market is a market highly specialized and sophisticated with some of the most complex and expensive

is extremely harmful to the environment. Hydraulic fracturing‚ or “fracking”‚ is the process of injecting millions of gallons of water into the ground to crack shale rock around a gas well. When the shale rocks around the wells are cracked‚ it allows natural gas‚ specifically methane‚ to flow into the wells. To fracture the shale rock‚ the water injected into the ground has to be at a very high pressure and is loaded with sand and about 40‚000 gallons of 600 different dangerous chemicals. Once

“Wonderful Life” Science has been around us since the beginning of times. In the book “Wonderful Life: The Burgess Shale and the Nature of History” written by Stephen Jay Gould‚ attempts to tackle one of the broadest issues that since can address‚ the nature of history itself. Gould’s main focus is on limestone quarry high in the Canadian Rockies known as the Burgess Shale. “Wonderful life” teaches the reader about animals and the evolution of our understanding of these animals’ relationships to

(BBC‚ 2012). Studies have shown that petroleum and certain natural gases are found beneath the earth’s surface in certain “reservoir rock formations” or “shale formations” (shales are defined as a certain type of sedimentary rocks) (geology.com‚ 2010). The gasses trapped beneath the earth can be classified into two categories namely shale gas and conventional gas. The reservoirs of

specific tool known as a Perforation Gun is deployed down the hole vertically and horizontally. When this gun is set off‚ it creates fractures in the Marcellus Shale‚ which is located along Pennsylvania‚ New York‚ and West Virginia. these fractures in the shale then begin to release methane gases. This is a problem because Marcellus Shale has enough natural gases to supply all USA gas needs for 14 years. They then pull out the perforation gun and enter another type of pipe. This pipe is unique because

The primary source rock is the upper Akata Formation‚ the marine-shale facies of the delta‚ with possibly contribution from interbedded marine shale of the lowermost Agbada Formation. Oil is produced from sandstone facies within the Agbada Formation‚ however‚ turbidite sand in the upper Akata Formation is a potential target in deep water offshore and possibly
