Abiotic Oil

What do you guys think of abiogenic petroleum origin?

Here is a website dealing with it if you don't know what I'm talking about: http://oilismastery.blogspot.com/

Seems pretty far fetched.

That sight looses considerable credibility by even going as far as to claim there isn't biogenic oil. There's lot of evidence going back nearly a century of the biological origin of crude oil, and we have a good understanding of the chemistry as well--including many chemicals that could only come from surface plants.

While there's little doubt that organic gasses can come from abiotic processes nothing in the article is compelling to show that those processes are happening on earth in large quantities. The only exception is probably methane that's a main constituent of volcanoes.

I do wonder about the early pre-biotic soup that some think existed prior to the origin of life. If it existed what happened to that sea of hydrocarbons?
