Shale gas and hydraulic fracturing (fracking)
www.doncaster.gov.uk/services/planning/shale-gas-and-hydraulic-fracturing-frackingShale gas is the same as the natural gas (methane) obtained from gas fields in the North Sea. Methane is the gas used for domestic heating, cooking and electricity generation. Shale gas is obtained direct from the source rock (shale, sandstone, limestone) which has to be micro-fractured to allow the gas to flow. The fractures are so small they are held open by grains of sand!
