with sand and chemicals to pump at high pressure into the shale rock. According to U.S Geological Survey (USGS) “This process is intended to create new fractures in the rock as well as increase the size‚ extend‚ and connectivity of existing permeability rocks like tight sandstone‚ shale‚ and some coal beds to increase oil and/or gas flow to a well from petroleum bearing rock formations”. The shale rocks contain the oil and gas. The shale rock will fracture from the fracturing fluid‚ which will hold

The quarry has exposed layers of limestone‚ shale‚ sandstone and coal. In Carboniferous times the land that became Britain lay astride the equator and was periodically covered by tropical seas‚ huge river deltas and rainforests. The tropical seas of the Carboniferous Period were full of life such

Do you remember in 2010 when every news station and every newspaper across the country had a headline about the BP oil spill? Do you think if America would have started converting to another resource such as wind‚ this would’ve still happened? Are oil and oil based products are taking over the economy? Think about everything you used today that uses or is made with oil such as gas‚ plastic‚ ink‚ and tires. Americans consume petroleum products at a rate of three-and-a-half gallons of oil and more

North Dakota estimated 5.5 billion gallons of water per year are used for releasing oil from Bakken shale. However‚ a statistic suggests that 70% of the water used in hydraulic fracturing gets contaminated‚ so 78‚571‚428 gallons of water got infected in North Dakota. Injected fluids can flow from the site where the hydraulic fracturing occurred to other

A social constructivist approach is relevant in understanding how knowledge and debates are formulated by differing social groups. Using this theoretical framework provides us with a background on how a technology‚ in this case hydraulic fracturing‚ is constructed through separate discourses. According to Bijker‚ “In the social construction of technology approach (SCOT)‚ relevant social groups are the starting point. Technical artifacts are described through the eyes of the members of these groups

Nucleolus Nucleolus is a small dense small dense spherical structure in the nucleus of a cell during interphase. The nucleolus is located inside the nucleus in the category eukaryotic cells. The nucleolus make ribosomal subunits from proteins and ribosomal RNA‚ here is a fun fact RNA could be also called rRNA.Ribosome makes proteins and nucleolus makes proteins inside a cell . A ribosomes they have two category‚ one is the large the other is the small. Each subunit is separately from nucleolus. Nucleolus

From meeting energy needs to creating jobs and helping the economy‚ natural gas is an invisible miracle. Many precautions are taken during the fracking process in order to ensure it is safe as possible. Natural gas is something I work around every day due

local energy sources in the United States poses many benefits. The oil and gas industry is one of the biggest industries in the United States. Fracking is the process of injecting water‚ sand and small amounts of chemicals into the ground‚ causing shale to crack‚ releasing natural gas. We don’t have a choice; we depend on fossil fuels every day to survive. Fracking provides many economic benefits that outweigh the disadvantages associated with the matter. As population increases‚ the demand for natural
