Thanks great report on the opportunities in the Bakken. Do your estimates include only the Bakken or also the Williston Basin. I have tended to notice the two discussed interchangably but it appears from your analysis they are separate as the Bakken is contained within the Williston Basin. Do you have any ideas on the Williston basins' productive capability?

This only includes the Bakken in the US. The Bakken is a subset of all the production in the Williston Basin, but it's the hottest play going at the moment in the Williston. It would not be difficult to do the same exercise for the Williston, but we'll leave that for another day.

There are probably quite a few different types of analyses that could be done like this.

It would seem like it would on other oil locations, like Gulf of Mexico, or shallow water separate from deep water in the Gulf of Mexico.

It might also work on natural gas, as with Barnett Shale in Texas.
