The British Geological Survey in association with the UK’s Department of Energy and Climate Change has completed an estimate for the amount of shale gas and oil in the Midland Valley of Scotland. The estimate is in the form of a range to reflect geological uncertainty. The range of shale gas in place is estimated to be between 49.4 and 134.6 trillion cubic feet (tcf), with the central estimate for the resource being 80.3 tcf.
The range of shale oil in place is estimated to be between 3.2 and 11.2 billion barrels (bbl), with the central estimate for the resource being 6.0 bbl. The relatively complex geology and limited amount of good quality constraining data (seismic reflection and borehole) result in a higher degree of uncertainty to the Midland Valley of Scotland shale gas and shale oil resource estimation than previous studies. The prospective shale intervals occur within a stacked rock sequence; individually shales are thinner than in many unconventional gas and oil systems worldwide.
