It is found in deep underground formations of natural rock along with other hydrocarbons like coal, methane clathrates, etc. (b) Natural Gas Reserves According to a recent assessment by the Potential Gas Committee the reserves of natural gas in the US have increased by 26 percent by the end of 2012 than it used to be in 2010. Now the present estimated reserve is 2,384 trillion cubic feet. The reserves of the natural gas in the US are primarily located in Texas, the Gulf of Mexico, Federal Offshore, Alaska, California, and North Dakota and Texas is the largest reserve (Cathy Proctor, 2013). Extracting natural gas from the ground is a complicated and expensive process. The gas is odorless and colorless requiring extra precautions. Extracting the gas from deep underground decreases the pressure in the reservoir and decrease in pressure might cause sinking of the above ground affecting ecosystem, water and sewer systems, water ways, foundations, etc. The process used to release the natural gas from low-permeability reservoir is called hydraulic fracturing or “hydrofracking”. Water is forced inside the shale to release the natural gas which breaks or fracks the shale for releasing the gas. Sand and chemicals are added to the frack fluid for reducing friction and combating corrosion. It is a challenge to deal with fracking fluid (Cathy Proctor, 2013).
