Canada wildfire evacuations curb oilfield, pipeline flow

(Reuters) - The wildfire that raged on Thursday in Fort McMurray in the heart of the Canadian oil sands region knocked out as much as a third of Canada's daily crude capacity and closed some pipelines. While oil sands facilities are not in the fire's path, seven production companies and two pipeline operators have curbed activities to take precautions to move workers and others to other areas. At least 690,000 barrels per day of capacity were offline on Thursday, according to calculations by Reuters. That does not include the unspecified reduction in Syncrude output or Suncor thermal operations, meaning the total is likely higher. Following is a list of what oil producers and pipeline companies have said about nearby operations: - Statoil ASA said production at its Leismer oil sands project has been cut by 50 percent to 10,000 bpd to preserve supplies of diluent, which is added to viscous oil sands bitumen so it can flow through pipelines. - Canadian Natural Resources Ltd said there had been some operations outages at its Horizon project, but current operations are stable. - ConocoPhillips said it had shut its 30,000 bpd Surmount operations and evacuated people and workers from the site. - Nexen Energy, a wholly owned subsidiary of China's CNOOC, said late on Wednesday that it was shutting its Long Lake oil sands facility. Long Lake can produce around 50,000 bpd of synthetic crude but has been operating at reduced rates since late January, when an explosion at the plant left two employees dead. - Suncor Energy Inc, whose oil sands operations are closest to the city, has closed its main mining site, which can produce up to 350,000 bpd. Before the shutdown, the site was operating at reduced levels because of a turnaround there. Due to the reduced availability of diluent in the region, the company said its thermal oil sands operations, including the Syncrude facilities, are all working at reduced rates. It said its main plant 25 km (16 miles) to the north was safe. - Royal Dutch Shell Plc said it had closed its Muskeg River and Jackpine oil sands mines, whose combined capacity is 255,000 bpd. - Husky Energy said it had cut production at its Sunrise oil sands project to 10,000 bpd from 30,000 bpd after a pipeline that supplies the project with diluent was shut down. - Connacher Oil and Gas Ltd said on Thursday morning it was bringing its Great Divide production back up to 8,000 bpd, after cutting it to 4,000 bpd on Wednesday. Great Divide is 80 km south of the city, and produced 14,000 bpd in the fourth quarter. - The Syncrude oil sands project, owned by a consortium of companies including Suncor, said it was reducing operations to help support employees affected by the fire. Syncrude has 2,000 evacuees staying at its camp. - The following oil sands companies with operations in the region said they were not affected: Imperial, a subsidiary of Exxon Mobil; Cenovus Energy; MEG Energy; and Japan Canada Oil Sands Ltd. Athabasca Oil Corp did not respond to requests on Thursday for an update on operations. PIPELINE COMPANIES: - Enbridge Inc was starting shutdown procedures, an Alberta government official said on Wednesday, without elaborating further. An Enbridge spokesman would not confirm, but said mainlines were not affected. They are 10 or more kilometers away from the fire and below ground, he said. Statoil said on Thursday Enbridge had stopped pipeline shipments out of its Cheecham terminal near Fort McMurray. Enbridge did not respond to a request for comment. - Inter Pipeline Ltd has shut down its Corridor pipeline system that serves Shell's oil sands facilities and partially shut down its Polaris diluent pipeline. - TransCanada Corp said it does not expect the wildfire to affect deliveries of natural gas. The nearest pipeline is about 20 km west of the current wildfire.
