North Dakota Governor Jack Dalrymple and industry leaders are holding a meeting in Bismarck to learn more about the future of pipelines in North Dakota.
The summit is happening today (Tuesday 24 June) at Bismarck State College's National Energy Centre of Excellence.
Dalrymple hosted a similar event two years ago that was attended by more than 100 industry and government officials.
North Dakota is the nation's number two oil producer behind Texas. The state is producing about 1 million bpd but about 70% of this is being moved by rail, as producers increasingly have turned to trains to reach US refineries, where premium prices are fetched.
Dalrymple says more pipelines will reduce truck traffic, curb natural gas flaring and create more markets for the state's oil and natural gas.
