Potential benefits of UK shale gas development
• Potential jobs created in the UK – 74,000
• £1.1bn over a 25 year period for local communities
• Lower wholesale energy costs that could total £17 billion between 2014 and 2035
• A 21% reduction in the UK gas import dependence
• Increased Energy Security

North West
• IGas’ 14 North West Licences contain a total of 170 tcf (GIP)
• Key players in the region are Igas, GDF Suez, Ineos
• It covers two shale basins namely the Cheshire basin and the Bowland-Hodder shale basin.
• There is a good shale presence in the Bowland-Hodder basin matching US shale plays notably Marcellus and Fayetville
• Shale has natural fractures
• Acreage is about 1,737km2

Scotland
• There is approximately 49.4 – 80.3 tcf (GIP) in the Broxburn
Shale horizon
• The estimate has a higher degree of uncertainty when compared to the Bowland-Hodder estimate
• Key players in the region are IGas and Ineos
• The PEDL 133 in the midland valley of Scotland licence which produces
