This link will download a PDF of the December, 2010, North Dakota Pipeline Authority summary of North Dakota's Oil Transportation Infrastructure.
As noted by "Bri-VA" these projections were based on 120 and 150 rigs. Currently there are 167 active rigs (high) in North Dakota. See 2nd comment.
I will post the link in the "Data Links" tab above.
Note: it is projected that North Dakota will produce 500,000 bbls/day by September this year (2011).
[Note: one day after posting, the Williston Herald posts a story that Enbridge will be putting in two short segments (26-mile and 29-mile segments) that will increase capacity by 145,000 bopd in the region.]
