Reserve estimates are just that...estimates. There is a decades long history of over or under estimating oil reserves for political or economic advantage. The doubling or tripiling of reserve estimates has been done before. Saudi Arabia is a classic example.
Besides it's not really a reserve issue, it's an extraction and refinement issue. Peak oil refers not only to reserve estimates, but to production results and available supply into the marketplace.
Good luck to us all.
