The British Geological Survey has just produced a report on Scotland's shale resources, similar to the headline grabbing one it did last year for the Bowland. As previously, this is an estimate of the oil and gas in the ground rather than an estimate of what can be economically extracted.
This study offers a range of total in-place oil resource estimates for the Carboniferous shale of the Midland Valley of Scotland of 3.2-6.0-11.2 billion bbl (421-793-1497 million tonnes) (Table 1). Total in-place gas resource estimates are 49.4–80.3–134.6 tcf (1.40–2.27–3.81 tcm). The West Lothian Oil-Shale unit makes the largest contribution to this estimated resource.
