Proactive maintenance, which reduced plant capacity by approximately 50%, has been taken late in July to replace a number of coker valves and to address some very localized pipe wall thinning in the amine unit.  Planned maintenance activity in August includes Ore Preparation Plant screen changes, and a routine pigging cycle.  August 2010 production is expected to be between 102,000 and 107,000 barrels per day of SCO.

The Company targets stable production levels of approximately 110,000 barrels per day of SCO for the remainder of 2010 and will continue to complete strategic maintenance as required.

Canadian Natural is a senior crude oil and natural gas production company, with continuing operations in its core areas located in Western Canada, the U.K. portion of the North Sea and Offshore West Africa.
