According to a government-commissioned report, more than half of the UK could be suitable for shale gas fracking.
The report says that under the maximum scenario, up to 2,880 wells could be drilled for oil or gas in a new licensing round, which would in turn generate 16,000 to 32,000 jobs.
BBC reporter John Moylan visited the British Geological Survey to find out which areas of the UK offer the best potential for fracking.
