North dakota oil production bakken
North Dakota crude oil production surpassed 1.0 million barrels per day (bbl/d) in April and May (the latest data available). This record is the result of increasing crude oil production from the Williston Basin's Bakken and Three Forks formations in North Dakota and eastern Montana. In April 2008, a report issued by the state of North Dakota Department of Mineral Resources estimated that the North Dakota portion of the Bakken contained 167 billion barrels (26.6 billion cubic metres) of oil in place.
