The shale gas deposit around Blackpool is 50 per cent bigger than previously estimated, The Times has learnt. The news will put more pressure on ministers who are due to lift the ban on extraction as early as next week, to support what could prove to be a gas bonanza for Britain. The British Geological Survey (BGS) is carrying out an independent analysis of shale gas reserves which it plans to publish in the new year. It is understood that the BGS will estimate that the 1,000 square kilometres covered by the Bowland Basin to the east of Blackpool contains 300 trillion cubic feet of gas, equivalent to 17 times the remaining known reserves in the North Sea. --Timm Webb, The Times, 8 December 2012
