I work with a former petroleum chemist and he says there is a geochemical case for abiotic oil. There are larger number of chemists in this field who do not demise this as bunk.
Read the “Hot Deep Biosphere” by the late Thomas Gold.
Gold is a relatively famous astrophysicist (Austrian extraction... I think his last academic posting was at Cornell.) He once was an associate of Hoyle & Bondi, in short he is no slouch ! The Wikipedia article on him is quite good!(Yes I know that Wikipedia is not an academically definitive source!)

I have read about Gold and for years I have read about the Russians who claim to to be producing abiotic oil from super deep wells. However, Russian production has been down or flat. Moreover, no one has been able to produce oil that does not contain biotic material and very, very few have been able to produce oil that does not contain markers of its source rock or reservoir rock.

In order to accept abiotoc oil theory you not only have to disregard all existing data in geology and chemistry but you also have to believe that the entire oil industry is involved in a mass conspiracy.
