It is wrong to say that 'nobody has a clue'

The quoted figures come from the British Geological Survey who have done quite a lot of work on it using geological models and seismic data gathered from existing wells and bore holes.

Whilst ('top down') data from producing wells would be useful and might mean that the estimates are revised. It would be wrong to completely dismiss their 'bottom up' approach to the estimate. And they would have to be staggeringly wrong if Bowland shale gas was going to have a substantive effect on energy security.
