(Reuters) - Wildfires raging through northern Alberta are forcing oil companies to chop production, with more than 100,000 barrels per day shut in, while smoke from the blazes prompts oil sands operations to evacuate staff.
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.
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. The company said on Thursday it had no indication of when it will restart, but the chances of that happened Thursday was deemed unlikely.
* Cenovus Energy Inc said its 22,000 bpd Pelican Lake heavy oil field, served by the Rainbow line, has cut output to 4,000 bpd as oil is pumped into storage tanks. They were expected to be full later Thursday, which would force a complete 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, also because of the Rainbow outage.
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 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 thermal 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.
The company said on Thursday it was limiting nonessential personnel at its 255,000 bpd Albian oil sands operation near Fort McMurray, which includes the Muskeg River and Jackpine mines, due to heavy smoke. Production has yet to be affected.
* Syncrude Canada Ltd evacuated nonessential employees and contractors from its Aurora oil sands mine north of Fort McMurray on Wednesday because of thick smoke from nearby fires. It said its facilities were not a risk.
* Apache Corp has shut in 6,200 barrels of oil equivalent a day at its Marten Hills, House Mountain and Kaybob properties due to the Rainbow outage and fire threats.
* Murphy Oil Corp has shut 6,000 bpd from the Peace River, Alberta, region due to the Rainbow outage.
* 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.
