Suncor Notes Oil Sands Production for January

Suncor's oil sands production during January averaged approximately 156,000 barrels per day (bpd). Production was impacted by unplanned maintenance activities following a fire at one of two upgraders (U2) in December. The repairs were successfully completed and the upgrader has returned to production.

Production numbers include upgraded sweet and sour synthetic crude oil and diesel, as well as non-upgraded bitumen sold directly to the market, from all Suncor-operated facilities. Reported volumes do not include Suncor's proportionate production share from the Syncrude joint venture.

On a monthly basis, Suncor reports production numbers from its oil sands operation in order to provide stakeholders with a more timely review of operational performance. These numbers are preliminary and subject to adjustment. Production volumes will be confirmed when Suncor's first quarter results are released.
