Pipeline crew setting in pipe. Jefferies says TC Energy ’s Keystone pipeline shutdown following a spill in Kansas creek to have a relatively minor impact on its coverage. Assuming shutdown for two weeks (for no other reason than precedent), crude sales in Q4 for Cenovus Energy , Canadian Natural Resources and Suncor Energy will be affected only by an estimated ~2.2%, ~0.2% and ~1.5%, respectively. Says production shouldn’t be impacted given excess storage regionally. The ~622,000-barrels-per-day pipeline was shut down after more than 14,000 barrels of crude oil spilled into a creek in Kansas, making it one of the largest crude spills in the United States in nearly a decade. TRP says it has not yet determined the cause of the leak and did not give a timeline as to when the pipeline will resume operation.
