There seems to be a lot of excitement in the blogosphere over this press release, claiming that there is a large oil field in North Dakota. From the looks of the map, I wonder if the field is some sort of extension of the tar sands in Canada.
That said, the release claims the oil is difficult to extract, and that only now, with prices as high as they are, is it economically viable.
If true, this would be great. However, like the occasional shale oil boomlet, I will believe it when I see oil coming out of the refineries.
