I think I see where we are missing each other. My meaning is that it is spatially continuous. There are no places that it drains to, it is just one wide layer or trap. Your meaning is that the oil is located where it formed (or nearly so). My picture is probably too simplistic, as some areas will have more oil than others and those will be the commercial portions. This model is a little above my head but it might help you get a feel for what people are thinking: http://www.searchanddiscovery.net/documents/2006/06035flannery/index.htm
Again, what is interesting to me is that there seems to be something to be remarked on in the aggregate production numbers from the conference call. Perhaps this is a slow motion discovery that is significant. I'm paying attention because I'm trying to figure out how much carbon dioxide needs to be cleaned up. An extra 20 years of US oil consumption could be a problem.

From peakoil.com: Finally, the Bakken makes the national media (NY Times). Lots of links there. Peak oil: Do you want it to occur? detoured into Bakken territory as well.

Also would love to see a TOD piece on this. API of 41 they say.
