Abstract: Within the UK there are several areas, including sizeable parts of north-west, central and eastern England, smaller parts of south and north east England, central Scotland and Northern Ireland, which have the potential to produce shale gas. Shale gas is produced by hydraulically fracturing shales, a process popularly known as fracking, which releases the gas and allows it to flow. This process typically involves drilling a borehole down into the earth and then using a mixture of water and chemicals, pumped at high pressure into the shale, to open up narrow fractures, which in turn creates paths for the gas to flow into the borehole and hence back to the surface.
