Delays of the Keystone XL pipeline are providing little obstacle to Western Canadian oil producers getting their crude to the U.S. Gulf Coast, with shipments set to more than double next year. The volume of Canadian crude processed at Gulf Coast refineries could climb to more than 400,000 barrels a day in 2015 from 208,000 in August, according to Jackie Forrest, vice president of Calgary-based ARC Financial Corp. The increase comes as Enbridge Inc.'s Flanagan South and an expanded Seaway pipeline raise their capacity to ship oil by as much as 450,000 barrels a day.
