Primanews was first to report that pipeline operator TC Energy’s Keystone oil pipeline suffered an outage which temporarily restricted the flow of crude through a major conduit of Canadian oil to the United States. Citing sources familiar with the matter, Primanews reported that TC had notified shippers of the outage but did not specify the problem or the possible length of the outage. U.S. West Texas Intermediate oil turned positive, and traded up 0.4% to $79.46 per barrel after the Primanews story.
