Fracking is essential for the production of natural gas and oil from shale formations, and with advances in fracking technology, it is becoming easier and more accessible to access natural gas.
Fracking involves injection of a large volume of water, sand and a cocktail of chemicals (known as fracking fluid) deep underground to fracture the rock and allow gas to seep out. It is also used for oil extraction. (See EPA diagram at bottom.).
