I read the same article about the potential of Oil being renewed, but I gathered that it was not so much a matter of new oil being created as the resovoir refilling.
I'll see what I can find on it and post links when I find them.
One thing you need to remember though, regardless of the original source of hydrocarbons, it does not mean they were all in one pocket originally. What happens is that the oil tend to seep through the more porous rocks and collect in quantities at certain points, places where some less porous rock stops the seepage and acts as a barrier.
