See, the thing is that people who talk like this don’t understand geology.
It doesn’t matter if oil is biotic or abiotic. It still only gets trapped in certain geological folds of rock. Where it comes from isn’t important in the context of recovery. All that matters is . . . where are those folds and how many haven’t already been drilled.
The stuff can be created by meteors if you want, and it won’t make any difference in how you find it. There has been 100+ years of drilling dry holes to learn what formations can hold it and what can’t.
Also, try to remember there is no ocean of oil underground when you have an “oil field”. It’s rock. There are bubbles of oil in the rock pores. There is “permeability” as a measurement of that rock (the interconnectedness of the pores). You can have a field with a billion barrels of oil, but if the pores are tiny and very far apart, you can’t frack them to create interconnectedness and each bubble is small enough that a 20 million dollar hold would only tap 10 barrels of oil.
This is why “we will never run out”. Those 10 barrel bubbles can be there and never be worth the joules required to get them.
All that’s happened is we came upon several unlimited supplies of diamonds so we can drill deeper, and lo and behold, there’s a lot of rock down there that used to be at the surface ~ proving only that 4.5 billion years is a really long time!
