FYI oil migrates upwards not downwards because water is heavier than oil. This is why we have oil seeps and why we used to have blowouts not blowdowns.
The oil industry disagrees

The source rocks are igneous not sedimentary. Sedimentary rocks are merely reservoirs.
Strawman - regardless of the nature of the source or reservoir rock - it can still migrate downwards through processes like subduction / burial etc.
At least I use links. You don't have any evidence whatsoever to support your case. Not one scientific paper. Not one scientific link.
Posting links and references that don't say what you think they say is worse that providing no links - a great deal of your links are merely op-ed, the science is either ignored, out-of date, or discredited - look at those google books links you posted - stuff from 1904 FFS!
here's some more links that you have misunderstood:
http://www.geotimes.org/june03/NN_gulf.html
- describes hydrocarbons being generated by jurassic marine carbonates - marine carbonates are predmoninatly biogenic.
http://www.worldnetdaily.com/news/article.asp?ARTICLE_ID=47673
Oil is seeping from sediments into granite - not being spontaneously generated from deep in the earth -furthermore Wallace G. Dow, an AAPG member and consultant in The Woodlands, Texas states "the oil's components indicate a lacustrine organic facies with lipid-rich, land-plant debris and fresh-water algal material, refuting theories of abiogenic origin in this area."

I have edited your Wikipedia article on this oilfield to include this information just in case someone gets misled by it
http://www.gasresources.net/DisposalBioClaims.htm
contradictory claims of biomarkers - Gold claims they ARE biomarkers from the hot deep biospehere - others claim they aren't biomarkers at all - fundamental contradictions like this need to be resolved to elevate this from hypothesis to theory

http://www.sciencemag.org/cgi/content/short/319/5863/604
describe the abiotic generation of methane by means of reactions with basaltic types rock - contradicts abiotic predictions of oil generated in granitic sequences.
Furthermore this does nothing to prove that all hydrocarbons are abiotic - indeed some of the articles stress the difference between biotic and abiotic hydrocarbons.
You have also been extremely selective with this
http://www.aapg.org/explorer/2002/11nov/abiogenic.cfmarticle - picking out bits that have suggestions of abiotic oil and ignoring the bits that don't agree 100% with what you say - its a technique called Quote Mining - its what creationists do.
I can quote mine from the same article look
Katz said Western science recognizes that abiogenic hydrocarbons can result from natural processes, including the possibility of hydrocarbons originating at great depth.
"I don't think anybody's arguing that gas couldn't be generated from the mantle," he said.
However, even the Russian scientists he has worked with accept the organic origin of petroleum found in large, commercial accumulations.
"I have yet to have anyone show me that there are commercial quantities of these hydrocarbons," Katz said.
"I'm a scientist, so I have to keep an open mind. But I need to see some evidence."
This is why I have asked
you to explain it
in your own words instead of relying on links that don't quite say what you think they say.
I'm doing you a favour pal - offering a way for you to look less of a fool
Finally to save you from complaining that you are not getting any peer review from other posters here, here's a doozie for you to refute:
http://www.osti.gov/energycitations/product.biblio.jsp?osti_id=7052010
the median abiogenic methane content of commercial gases is estimated to be less than 200 ppm by volume
this calculation suggests that little confidence should be placed in the resource potential of abiogenic natural gas
