In 2007, the North Dakota State Legislature created the North Dakota Pipeline Authority to assist development of pipeline facilities to support energy-related commodities.
There are close to 20,000 miles of gathering and transmission pipelines in North Dakota (2013). This has increased from 11,700 miles in 2009, a 70 percent gain. The United States has the largest network of pipelines in the world.
North Dakota makes use of three product pipelines, 15 major crude oil pipelines, nine major natural gas pipelines, and one carbon dioxide pipeline. Several additional pipeline projects to transport the increased oil and gas production in the state have been proposed or are in the planning stages. The North Dakota Pipeline Authority provides a great resource of maps of these pipelines.
In early 2015, the N.D. Pipeline Authority reported that 60 percent of oil transportation occurred through rail transport, roughly 33 percent through pipelines, and the remaining oil went directly to the in-state Tesoro Refinery and via truck to Canadian pipelines. These percentages change rapidly depending on the Brent – WTI (West Texas Intermediate) price spread.
