Hi Chris
Thank you for your reply. And thank you for your paper reference - I'll
take a look at your probability plots.
Yes the apparent lognormality of oil and gas fields which moves more to a
Pareto form with progressive and mature exploration is explained by
undersampling at the low end

Hello list
I am a PhD student looking at developing a statistical model to predict
the size-distribution of an area's oil and gas fields.
It is clear that previous investigators prefer either a Pareto power law
or a lognormal distribution to approximate field-size distributions.
The data I
