Where does oil come from? Update

Many years ago I posted: An Englishman's Castle: Where does oil come from?

It is still one of my more popular posts in terms of readers and requests, such as this one from Hayley:

hi im duin a skwl project on oil and need 2no where it cums from can u help me???

For her and other scholars the theory that oil was and is being formed by abiogenic processes has had another boost;

An article in Science today seems to suggest that the abiotic theory is correct. In a fairly dense article entitled "Abiogenic Hydrocarbon Production at Lost City Hydrothermal Field,"
researchers Proskurowski et al., find evidence of the abiogenic
formation of short-hydrocarbon chains in an area where hydrocarbons would not otherwise be able to form by the biogenic theory.

The biogenic and abiogenic processes of oil formation are clearly wrong as any fule kno Arab scientists made oil but the secret was stolen and lost by the Crusaders. That explains why so much of it is in the Middle East. Taken from the NuLabour Book of Herstory so it's true.

Hey - where do you think the methane atmospheres on Jupiter and Saturn came from? Must've been trillions of dinosaurs breathing it out. :-P

In fact, 99% of the hydrocarbons in the earth's crust were originally formed at the same time as 99% of the hydrocarbons in the rest of the solar system: in the early stages of the accretion disk that evolved into the planets. Then high temperatures and pressures inside the Earth would have polymerized the methane into longer chain molecues.

That's my Cosmic Methane theory. :-)
