The Energy Information Administration (EIA) Assignment

The slide fastener Information Administration (EIA) - Assignment Examplein the extraction process, oil sands production follow is relatively high and therefore investments in oil sands argon quite sensitive to unflinching changes in oil prices. Gas emissions into the air, water pollution, toxic tailing ponds and the chances of oil spills from pipelines in the oil producing areas are environmental concerns in tar sand processing (Miller 456).According to Kuuskra( 3), shale is a close grained, sedimentary quaver made up of mud from flakes of clay minerals and small particles of other materials, which is processed to produce natural suck and oil. Large deposits of shale are found in United States, China, Argentina, Algeria, Canada, Mexico and Libya (kuuskra 9).Extraction process starts with identifying economically viable healthful areas. Then, horizontal drilling and hydraulic fracturing methods are used in the extraction process.In the hydraulic fracturing method, hydrocarbon in a shale formation is released by injecting water, chemicals and sand into a well. Release of the hydrocarbon opens fractures in the rock allowing the natural gasoline to flow into the well. (exploration and extraction of shale 10).Use of both methods together enables economical extraction of the shale gas. Unfortunately, mining of shale leads to pollution of the environment through emission of toxic gases in the air and also a poses a great danger to aquatic life if poisonous materials leaks in to the
