Well, I dunno what to say that hasn't been said on here already bigfish.
There appears to be some evidence for abiogenic hydrocarbons along with a lot of evidence for biogenic hydrocarbons, but from the point of view of this thread the key issue isn't the formation method, it's supply vs demand.
To make any real difference to that sort of discussion, I think the abiotic theorists need to demonstrate either the strong version of their thesis (ie that abiotic formation happens faster than projected exploitation) or that the oil industry has simply overlooked significant reserves because they're located in places where the biotic theories predict that they can't occur (e.g. in the basement rock). I'm unaware of any particularly convincing evidence to that effect despite reading the various links you've posted to this thread so far.
It's also worth bearing in mind that constraints on petroleum, natural gas etc production are just one set of constraints significantly affecting the future of the human race. They're important constraints, because oil-input agriculture is a fundamental reason why global resource use has reached levels which are probably unsustainable without a large supply of cheap oil and gas, but they are by no means the only significant constraints. There is a whole system of such constraints, also including climate change, the degradation of ecosystem services and so on. The issue here being that if the strong abiotic thesis were shown to be true, then the likelihood is that we face the more extreme climate change scenarios predicted for levels around 1000ppm of CO2.
To avoid both horns of the dilemma, we need to moderate our use of oil and gas in a controlled way, rather than having hundreds of millions die horribly.
