CALGARY, Alberta, June 1 (Reuters) - Firefighters made progress tackling wildfires in the key oil-producing region of northern Alberta on Monday that shut in 10 percent of total oil sands production and workers are beginning to return to assess the damage.
For more than a week, 233,000 barrels per day of oil sands crude has been shut in after companies with facilities close to uncontrolled wildfires rushed to evacuate staff. The Western Canadian province of Alberta is the major source of U.S. oil imports.
Canadian Natural Resources Ltd said it has been allowed access to its Primrose oil sands project in Alberta's northeast, where production was suspended and workers evacuated due to the wildfire threat.
"A Canadian Natural team of operational staff were permitted access to implement a ... recovery plan, including the inspection of facilities and equipment, and the completion of repairs, if required," the company said in a statement. "Following this assessment, pre-start activities towards resuming full operations will begin."
Canadian Natural said the assessment will determine when 80,000 barrels per day of production can resume.
Over the weekend the number of fires dropped to 35 from 42 on Friday. Five are classed as out of control.
