UK shale gas reserves may be ‘bigger than first thought’ June 3rd, 2013 admin Latest News Shares Comments One of the energy firms hoping to exploit the UK’s resources of shale gas says it may be sitting on significantly more gas than previously thought. UK firm IGas says there may be up to 170 trillion cubic feet (4,810 cubic km) of gas in the areas it is licensed to explore in northern England. But it remains unclear how much of the gas will be economically extractable. Shale gas is extracted by fracking – pumping water, chemicals and sand at high pressure into rock to release gas. Critics argue that the process may cause earth tremors and want investment in green energy. Fracking has revolutionised the US energy market and the energy industry has hopes for a similar transformation in the UK. ‘Benefit communities’ Visit BBC link below for full story http://www.bbc.co.uk/news/business-22748915 Related Comments comments!
