Keith, I'm confused as to the relevance of abiotic over biotic sources of oil.
Given that Hubbert predicted the decline of US fields, I think his approach may be relevant for any given field, whether abiotic or biotic. Even if the source were to be abiotic, I think the problem is resource depletion. Given our timescales, I would say that arguing over the where oil comes from is a moot point as fields tend to show similar output curves. Reserve growth or replenishment doesn't appear to have any solid foundation in history (although I'd be glad to be proven wrong). If oil is abiotic, it has still had many millions of years to form. At our current rate of usage, I don't think easily accessible fields will just renew themselves. I guess the only difference would be that there may be sources elsewhere where the western geologists haven't looked, due to their assumptions over where the deposits may lie. This doesn't seem to change the theory of peak oil (for a given field) for me. It's true that there are some elements in the peak oil crowd who have a dieoff agenda. But these are not in the majority, even if they are vociferous. I don't think that believing that oil will follow a traditional hubbert curve is necessarily either a scam from the oil companies or a reason to dribble over forced population reduction. It can also help individuals to decide for themselves that a more local and appropriate use of resources is the only way forward. Believe me, there are many who frequent the peak oil forums who have come to this conclusion. I'll leave it at that for now.
