The Bakken and the Permian show almost no change month-over-month. Interestingly enough, the Eagle Ford showed the "biggest" change, albeit trivial in the big scheme of things. It surprised me because so many writers / analysts have suggested the Eagle Ford is the fastest declining oil field in the country.
