The drilling for oil has clearly shown it it layers, trapped beneath different impermeable rock layers that hold the oil. If these cap rock layers didn't exist, the oil would not be trapped there.
How do you think that oil moved above one cap layer to then reside beneath another cap layer, but is still trapped beneath the lower layers as well?
And these oil deposits contain microfossils. And oil found under the same surface area, often have greatly different qualities like sweet/sour, heavy light, etc.

Aboitic theorist have produced cash from gullible investors and sometimes governments, but no commercial oil.
