So although this is unusable, it's interesting to note that not only is there abiotic methane (i.e. natural gas) formed in a gigantic deposit on saturn's moons, but it turns out there is also abiotic oil and coal in space. Perhaps some of our own oil and coal were abiotically formed?
This is only interesting from a scientific perspective however, because even if large deposits of abiotic oil or coal were formed, we've still found most of it and still are unable to continue increasing production endlessly. Peak oil is still going to happen because it's a limit on effectively how fast you can pull it out. Where we're arguing is really about decline rates, but regardless this post is about abiotic oil.
Turns out that "Prof. Sun Kwok and Dr. Yong Zhang of The University of Hong Kong show that an organic substance commonly found throughout the Universe contains a mixture of aromatic (ring-like) and aliphatic (chain-like) components. The compounds are so complex that their chemical structures resemble those of coal and petroleum. Since coal and oil are remnants of ancient life, this type of organic matter was thought to arise only from living organisms. The team's discovery suggests that complex organic compounds can be synthesized in space even when no life forms are present."
Interesting. We apparently haven't learned all there is to know about petroleum just yet.
