With temperatures from North Dakota to Northern Alberta below zero Fahrenheit (-18 Celcius), TC Energy Corp.’s Keystone pipeline was shut late Tuesday, with the cold slowing oil flows and making it hard to restore service.
In North Dakota’s Bakken shale, production has started to succumb to the freeze, sending local crude prices to their highest since November. Canadian oil has also jumped.
The disruptions mean less supplies at a time when U.S. stockpiles have been shrinking every week since mid-November and getting closer to September’s three-year low. Drillers have been slow to restore output to pre-pandemic levels as they prioritize shareholder returns over growth.
This further supports growing predictions that the oil market will return to a deficit this year, with some like Pioneer Natural Resources Co. Chief Executive Officer Scott Sheffield expecting oil to range from $75 to $100 a barrel.
Even though Western Canada and North Dakota are usually cold this time of year, temperatures have been lower than usual.
Western Canadian Select crude’s discount to the U.S. benchmark has shrank by almost $3 dollars since Dec. 27, to $12.10 per barrel on Wednesday.
Bakken crude in the Clearbrook, Minnesota, hub rose 90 cents a barrel in the past two days to reach a $1.25 premium to Nymex futures Wednesday, a two-month high. The same grade traded this week in Wyoming at a premium to New York futures for the first time since Nov. 18.
Keystone carries 590,000 barrels a day of Canadian oil from Alberta to the U.S. Midwest.
TC Energy said it’s working to safely restore service as soon as possible but its staff are challenged by extremely cold temperatures impacting the oil flow through its Hardisty terminal. Temperatures there fell to about -24 degrees Celsius (-11 Fahrenheit) on Wednesday afternoon.
Meanwhile, Enbridge Inc. said it was seeking crude supplies for its main pipeline system across Canada and U.S. to keep its pipes running at scheduled rates.
