Norway can be considered as the poster child of the Hubbert curve modeling approach with a production profile that is remarkably close to the logistic curve. Last time, we attempted to apply the Parabolic Fractal Law (noted PFL) to Saudi Arabia. Despite using very partial data, the PFL seemed to point toward an Ulimate Recoverable Ressource (URR) around 250 Gb when the PFL curvature is set to the value -0.07 established by Jean Laherrère for the entire world. In the present post, we propose to apply the same approach on Norway's oil field size distribution. The results seem to confirm that the PFL with a curvature value around -0.07 could be a good predictor of the URR.

[editor's note, by Prof. Goose] Hey folks, see these buttons to the left? Note that they include reddit and digg. If you recommend TOD articles at these sites (account required, but they take seconds to set up, and once setup and logged in, all you have to do is click!), we can get more traffic driven over here! Do it for every article you think is worthy.
Many natural object
geometry are well described by a fractal
(e.g. a
coastline). In particular, fractal self-similarity is a
powerful concept that has been investigated by Benoît
Mandelbrot. However, in practice the self similarity law is
not always perfectly respected. To remedy to this, Jean
Laherrère has proposed the Parabolic
Fractal Law (PFL) which adds a parabolic deviation to the
pure self-similar law, I quote: A complete or near complete
distribution of the larger objects, which in practice are usually
readily identified and quantified, can be used to define the parabola
following a rule of self-similarity, and hence describe the full
distribution down to the smallest object. The distribution can in turn
be used to determine the total population of the objects. I
believe that the PFL could be a complementary tool to analyze
production data under a different angle especially when the Hubbert
Linearization technique does not produce a clear result. For instance,
when applied to the United
Kingdom production data, the resulting Ultimate Recoverable
Ressource (URR) is very close to the value estimated by the Hubbert
Linearization technique. I intend here to apply this technique to Saudi
Arabia oil fields. Despite using coarse oilfield size estimates, the
PFL seems to point toward an URR close to the ASPO estimate at 270 Gb.
