Keystone Pipeline Is Likely Source of Oil Spill, Says TransCanada

TransCanada Corp. said its Keystone pipeline, which carries Canadian crude to the U.S., was likely the source of an oil spill in Missouri that prompted the company to shut a segment of the line.The disruption comes as U.S. Gulf Coast refiners seek alternatives to heavy crude after sanctions on Venezuela effectively cut off access to the country’s oil. Canada’s oil-sands crude serves as a similar substitute, but Alberta has struggled with pipeline bottlenecks that have forced rationing on export pipelines and prompted the province to impose mandatory production curtailments.
