CALGARY, ALBERTA--(Marketwire - Dec. 2, 2010) - Suncor Energy Inc. reported today that the company's oil sands production during November averaged approximately 325,000 barrels per day (bpd). Year-to-date oil sands production at the end of November averaged approximately 279,000 bpd. Suncor is targeting average oil sands production of 280,000 bpd (+/- 5%) in 2010.

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. Monthly totals may differ from the year-to-date total due to rounding, the impact of sales and changes in inventory. Production volumes will be confirmed when Suncor's fourth quarter results are released.
