Ok, it's hypothetically possible that there could be very deep sources of abiogenic oil deep within the earth. Hypothetically, as in far out thought experiment, but no evidence that I've ever heard of. Is it possible to access it directly? Or are we talking temperatures where drill pipe melts? Can it be accessed economically? I seriously doubt it.

But I think it's all academic anyway, the world is shifting to renewables, or at least a lot of it. The developed world will pave the way with the technology, and the rest will slowly follow along due to political pressure, or possibly the price of crude. If much of the world stops most oil production, third world poop holes are going to have a hard time producing their own in hard-to-access locations requiring advanced and expensive technology.

If fusion technology makes some big advances, that will be the end of most oil demand. Still be some for niche applications, mostly related to chemical production vice energy. They could even go far with advanced fission energy, if they can get over some political hurdles.
