Not trying to put you on the spot but as a practicing geologist can you explain why oil reservoirs show a probability distribution that is 1/Size2?

Or do geology schools never teach or theoretically discuss why a certain statistical distribution comes about?

Web,

Explain "1/Size2" please.

That is telling. The volume size probability distribution goes as 1 divided by the square of the size of the reservoir. That means that for reservoirs that are 10 times larger than a particular size, they are 100 times more rare.
