How "Big" Is The Bakken? -- The Williston Basin, North Dakota, USA

Crude oil supply growth will double from 2011-16, including production increases of 547,000 b/d in the Williston Basin and 131,000 in the Utica Shale. Anticipation of U.S. and Canadian crude oil supply growth is leading to significant U.S. infrastructure projects in all sectors of the industry, including more than 75 crude oil pipeline projects, 25 crude oil rail projects and seven crude oil refinery expansions.

If I read that correctly, "increases of" when added to current 500,000 b/d, puts the Williston Basin easily over one million bopd.

Now if only the administration would get on board.
