Very little oil is found at deep depths (greater than 20,000 feet subsurface), and it all seems to be related to temperature and pressure. The cooler rocks and basins, like the Permian Basin of West Texas, have the deeper oil reservoirs.

Generally, the deeper you go, the more likely the hydrocarbons are to be natural gas, not oil. As it gets hotter and deeper, even that is cooked off and what is found is mostly carbon dioxide or hydrogen sulfide.

That's my main objection to the theory that oil or gas is oozing up from deep inside the earth. It's too hot for it to exist there in the first place.

I could accept a theory that at least some of the natural gas is methane which is being spun off of the hotter earth material, but I think oil is a much harder sell.

I'm glad someone here knows what he's talking about. I find it amazing that the jury is still out on where oil came from in the first place.
