Canadian Natural Resources Limited Provides Update on the Scotford Upgrader
Canadian Natural Resources Limited ("Canadian Natural" or the "Company") provides a follow up report on the event which occurred at the Scotford Upgrader, in which the Company has a 70% interest, on Monday April 15, 2019 at approximately 8:45am. Shell Canada, as Operator of the Scotford Upgrader, along with Strathcona County Emergency Services responded to a fire in the upgrader expansion area ("North Upgrader") at the Scotford Upgrader, while it was being shut down for planned maintenance. The fire was promptly extinguished, all personnel were accounted for, and there were no reported injuries.

The fire was contained to a process furnace in the North Upgrader, while operations at the base upgrader plant ("South Upgrader") were not impacted by the fire. While the cause of the fire is being investigated by the Operator, an assessment is underway to determine the extent of damage to the North Upgrader and the cost and timing for repairs are yet to be determined. The investigation and planned maintenance activities continue on the North Upgrader.

The planned 38 day turnaround at the Scotford Upgrader is targeted for April and May 2019, during which time the South Upgrader will run at a restricted gross processing rate of approximately 200,000 bbl/d of SCO. Upon completion of the planned maintenance, May and June average gross production at the Albian mines is targeted to be approximately 245,000 bbl/d versus the Company's previously targeted gross curtailment production volumes at the Albian mines of approximately 255,000 bbl/d. The Company continues to optimize other assets in Alberta to mitigate the impacts of curtailment on its production.
