There has always been chatter that the Three Forks formation will produce wells every bit as good as the middle Bakken, and perhaps better.
As you scroll through this site, note the outstanding Helis Three Forks wells in the Grail oil field, and the nice TFS wells being reported by Whiting.
Most of the TFS wells will be in the south/southeastern edge of the Williston Basin profile. Though somewhat dated, this article will help bring you up to speed on formations in the Williston Basin. For those serious about the North Dakota oil and gas industry, the link should be bookmarked.
