Jurassic Shale of the Weald Basin shale oil and shale gas resource estimation
The British Geological Survey (BGS) in association with the Department of Energy and Climate Change (DECC) has completed an estimate for the amount of shale oil and shale gas in the Weald Basin in south-east England.
The estimate is in the form of a range to reflect geological uncertainty. The range of shale oil in place is estimated to be between 2.20 and 8.57 billion barrels (bbl) or 293 and 1,143 million tonnes, but the central estimate for the resource is 4.4 billion bbl or 591 million tonnes.
No significant gas resource is recognised using the current geological model. This is mainly because the shale is not thought to have reached the geological maturity required to generate gas.
