Much of Bakken crude oil from western North Dakota is leaving the state via rail.
State mineral resources director Lynn Helms says 47 percent of Bakken crude is shipped by rail, compared with 43 percent by pipeline – and ten percent by truck. Helms says the reason is financial.
"It allows us to displace foreign crude oil that would come in from the North Sea of the Pacific Rim into the East or West Coast," said Helms. "The pipelines only get us to Cushing, Oklahoma, or once the Keystone XL pipeline is in place, to the Gulf Coast."
