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.
