review Oil (petroleum) 2003

Microbes made heavy oil

Head, Jones and Larter argued most of the world's oil was biodegraded by microbes under anaerobic conditions, often producing methane, turning it into heavy oil.

As reported in: Head, Jones, Larter (2003). Biological activity in the deep subsurface and the origin of heavy oil. Nature. doi:10.1038/nature02134
