TULSA, Oklahoma - A proposed 1,300 mile crude oil pipeline from North Dakota to Cushing has been called off. In a news release from Tulsa-based ONEOK Partners, the $1.8 billion Bakken Crude Express Pipeline won't be built, because the company couldn't find enough producers to promise long-term use of the pipeline.

"Despite the robust outlook for crude-oil supply growth in the Williston Basin in the Bakken Shale, we did not receive sufficient long-term commitments under the terms we needed to construct the Bakken Crude Express Pipeline," said Terry K. Spencer, ONEOK Partners president.

The proposed pipeline would have had the capacity to transport 200,000 barrels per day of light-sweet crude oil from the Bakken Shale in the Williston Basin in North Dakota to the crude oil market hub in Cushing.
