I'm inclined to agree that petroleum is biological in origin. About the only problem I'm aware of with the theory is the absence of known petroleum sources in Cambrian and Pre-Cambrian sedimentary rocks. There's lots of evidence for abundant life in those rocks, but, so far as I know, no formation older than the Ordovician has petroleum deposits. Any thoughts — like that, not being a petroleum geologist, I don't know what I'm talking about?
