Oil jumped to number 4 among oil producing states in the United States this past year.
Last year (2009) North Dakota set a record in oil production for the state: 80 million barrels.
2010: we've already surpassed that level of production and it is estimated that North Dakota will produce 110 million barrels in calendar year 2010. This represents a 38 percent increase over 2010, and everything suggests 2011 will be even bigger.
How big is the Bakken? North Dakota oil production now represents six percent of total US production, up from one percent less than three years ago.
