That's interesting. So for oil R/P is about 10 but for coal R/P jumps around. Does it jump around some median value in a white noise or Gaussian kind of way. In Deffeyes' book he uses anthracite coal (I think) as an example which does follow a Hubbert-type curve.

Hi Dudley,

Here is PA anthracite, with the cumulative and the gaussian fits. The reserves are indicated by circles. The reserves are too high, and they do not come down until too late.
