What date is that? Petrochemicals aren't all stored in a big tank somewhere. My model is that there are many marginal sources which are not cost-effective to exploit, but which could be exploited with better technology or at a higher cost. I do not think we will ever extract all of these; instead, the cost of extraction will increase gradually, shifting incentives towards other energy sources.
I don't think anyone really knows what the future will look like.
