Suncor Energy provides operational update

Suncor Energy provides operational update 
CALGARY, ALBERTA -- (Marketwire) -- 12/06/12 -- Suncor Energy today
provided an update on its Firebag in situ facility, Oil Sands Base
plant, and the Terra Nova Floating, Production, Storage and
Offloading (FPSO) facility. 
The company reports that it has achieved first oil throughput at its
Firebag 4 facility. Firebag 4 was safely commissioned during the
third quarter, approximately three months ahead of the original
schedule. The Firebag complex exited the month of November producing
approximately 130,000 barrels per day (bbls/d). 
As a result of unplanned maintenance in early November at Suncor's
Oil Sands Base plant, November oil sands production was lower than
anticipated averaging approximately 312,000 bbls/d. Maintenance
issues have been successfully resolved and the oil sands plant exited
the month producing in excess of 380,000 bbls/d. No significant
maintenance is planned for the month of December and the company
expects the facility to produce at full rates for the remainder of
the year. Despite the maintenance issues in November, it is expected
that oil sands production for 2012 will be at the lower end of the
guidance range of 325,000 to 340,000 bbls/d. 
Production numbers include upgraded sweet and sour synthetic crude
oil and die
sel 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. 
In the Exploration and Production business, the Terra Nova FPSO
facility operating offshore Newfoundland and Labrador is in the final
stages of commissioning in preparation for start-up following planned
maintenance. The FPSO is expected to return to full production rates
around the end of December. 
Suncor expects total production to be within the company's annual
guidance range of 540,000 to 580,000 barrels of oil equivalent per
day.

Certain natural gas volumes have been converted to barrels of oil
equivalent (boe) on the basis of one barrel to six thousand cubic
feet. Any figure presented in boe may be misleading, particularly if
used in isolation. A conversion ratio of one bbl of crude oil or
natural gas liquids to six thousand cubic feet of natural gas is
based on an energy equivalency conversion method primarily applicable
at the burner tip and does not represent a value equivalency at the
wellhead. Given that the value ratio based on the current price of
crude oil as compared to natural gas is significantly different from
the energy equivalency of 6:1, utilizing a conversion on a 6:1 basis
may be misleading as an indication of value.
