"Economic and environmental aspects of Fracking -
Fracking is an economically beneficial and essential process for oil companies. Fracking is a process of drilling and injecting fluid into ground at a high pressure to fracture shale rocks to release Hydrocarbons, but it has raised certain environmental concerns that that have burdened oil companies to overlook at the processes they are using to extract hydrocarbons. Certain concerns about Fracking are:
Hydraulic fracking is quenching the water resources - 9.5 million gallons of water is used daily in places like Texas and California; out of which Natural gas devolvement (fracking) consumes 1.9 Millions gallon per day on the contrary livestock uses 62 Million gallons per day, mining uses 96 Million gallons per day and industry uses 770 Million gallons per day. Fracking does require a large volume of water but it is not negligible that it is comparatively small when put in context of broader public demand. Still, to solve this issue states and oil and gas operators are pursuing to make use of seasonal changes in river flow …show more content…

Seismic traces of fractures showed that the fractures extending more than 350 meters was around 1 %. Most fractures were between 200-400 meters. Whereas, aquifers are occasionally found at great depths and fracking companies ensure to maintain a safe distance between the aquifers and the fracking zone.
