(Reuters) - Oil companies cut more production in northern Alberta on Tuesday as they moved to protect employees and installations from wildfires raging through the region and cope with the shutdown of a key pipeline.
Spurred by warm temperatures and gusting winds, 100 wildfires were burning in Alberta with 23 considered out of control. The worst damage was concentrated in the Lesser Slave Lake region, about 200 km (125 miles) north of Edmonton.
Canada is the largest supplier of oil to the United States, exporting more than 2 million barrels a day. The amount shut in by fires and outages is a small percentage of that total.
Following is a list of energy companies affected by the wildfires.
Plains All American Pipeline LP shut the southern portion of its Rainbow pipeline on Sunday, from the Nipisi terminal 80 km (50 miles) northeast of Slave Lake, Alberta. The southern leg of the line carried about half the line's 187,000 barrel per day capacity at last report.
Cenovus Energy Inc said its 22,000 bpd Pelican Lake heavy oil field, served by the Rainbow line, has cut output to 11,000 bpd as oil is pumped into storage tanks. They are expected to fill early on Thursday unless the company further slows production to buy additional time before a full shutdown.
Canadian Natural Resources Ltd said it was slowing output at its 40,000 bpd Pelican Lake heavy oil operation ahead of an increasingly likely shutdown by Wednesday, when the tanks will be full.
Another 3,125 barrels of oil and 8 million cubic feet of gas a day have been shut in by the company in areas threatened by fire.
As well, it has evacuated about 1,300 people from work camps near its Horizon oil sands project near Fort McMurray, Alberta. Repair operations to the facility, following an explosion in January, have been halted in recent days.
Penn West Energy Inc has 25,000 to 35,000 bpd shut in the region affected by the fires. Along with some lost output because of flooding in Manitoba, the company has suspended up to 40,000 bpd of oil.
Royal Dutch Shell Plc shut in production from its Cliffdale and Seal heavy oil fields and slowed output at its Peace River in-situ operations -- all served by the Rainbow pipeline. Though the company did not specify how much production was shut in, the operations pumped about 21,000 bpd last year, with half of that coming from the Cliffdale and Seal properties.
Pengrowth Energy Corp said 5,000 bpd of its oil equivalent production has been halted.
Exall Energy Corp is shutting in 921 barrels of oil equivalent a day from its Marten Mountain field after Enerchem International Inc , which buys the field's production, declared force majeure at its Slave Lake plant. The company said its facilities are not affected by the fires.
BlackPearl Resources Inc halted 700 bpd of oil production at Mooney near Slave Lake and stopped construction on polymer facilities at the site. It said the facilities have not been damaged but employees had to leave because of evacuation orders.
Baytex Energy Corp has shut about 500 bpd of conventional light oil production from its Red Earth field.
