CALGARY, July 7 /PRNewswire-FirstCall/ - Suncor Energy Inc. reported today
that production at its oil sands facility during June averaged approximately
306,000 barrels per day (bpd). Year-to-date oil sands production at the end of
June averaged approximately 289,000 bpd. Suncor is targeting average oil sands
production of 300,000 bpd (+5%/-10%) in 2009.
In addition to Suncor's proprietary production of sweet and sour synthetic

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 year-to-date total due to rounding,
the impact of sales and changes in inventory. Production volumes will be
confirmed when Suncor's second quarter results are released on July 22, 2009.

This news release contains forward-looking statements, including an outlook
production range of +5%/-10%, which are based on Suncor's current
expectations, estimates, projections and assumptions and are subject to
change. Assumptions are based on management's experience and perception of
historical trends, current conditions, anticipated future developments and
other factors related to Suncor's business. Assumptions of the 2009 outlook
include implementing reliability and operational efficiency initiatives which
we expect to minimize unplanned maintenance in 2009. Readers are cautioned
