Tesoro: Better Yields Bolster Value of Railed-in Bakken Crude

Tesoro Corp sees continued value in railing North Dakota Bakken crude to its Washington state refinery despite higher costs because of improved yields, Chief Executive Greg Goff told analysts on Thursday.

"We still see economic value to be able to move Bakken to the West Coast and achieve the benefits that we have always stated, which primarily are driven by the yield improvements in the refineries," he said.

Bakken's discounts to other crudes have narrowed in the fallout of the global oil price rout, siphoning some profitability of oil-by-rail.
