In the UK, the regulators will require full disclosure of chemicals used in fracking fluid and they do not permit use of hazardous chemicals.

Mitchell ・The father of fracking, George Mitchell, was the embodiment of the American dream. Mr Mitchell had to work his way through university, but graduated top of his class. He left a fortune of more than $2 billion and a Texas landscape studded with examples of his philanthropy. ・He started injecting high-pressure fluids into the ground to fracture the rock and create pathways for the trapped oil and gas(fracking)and drilling down and then sideways to increase each well’s yield(horizontal drilling). ・Fracking; was first tried in the late 1940s and helped along by Department of Energy research in the 1970s. During the 1980s and early 1990s, Mitchell Energy drilled well after well, many of whose sites were determined personally by Mitchell, for 15 years, the company struggled to show that its fracking could produce reliable and economical gas. ・Running out of funds to keep drilling, an employee decided to substitute water for the more expensive silicone mixture being used. The process worked and in 1997 established that fracking could prove financially viable over the long term. ・Not long after, Mitchell sold his company for $3.5 billion. By then, fracking was on its way to resurrecting America’ s oil-and-gas industry. ・New horizontal drilling techniques made shale gas wells even more productive, and by 2012, shale gas accounted for about 35 percent of the country’s natural-gas production.

Although the overall demand for energy is decreasing in the UK, due to increased energy efficiency and less demand from energy intensive industries, the baseline need for energy is still quite significant. The North Sea is a mature field, and production is at an all-time low. The UK energy policy therefore needs to accommodate the void created by the lack of sufficient domestic production.
