By Edward Welsch Of DOW JONES NEWSWIRES CALGARY -(Dow Jones)- The Syncrude oil-sands project in northeastern Alberta is operating at reduced capacity after a fire at its refinery, a spokeswoman for the project's largest stakeholder said Monday. A fire late Friday at one of three coking units at the Syncrude project will reduce Syncrude's production to two-thirds of its normal capacity of 350,000 barrels of oil a day, said Siren Fisekci, a spokeswoman for Canadian Oil Sands Ltd. (COS.T). There is no word yet on when the coker will be restarted, or what caused the damage, Fisekci said. Syncrude is a joint venture operated by Imperial Oil Ltd. (IMO). The other stakeholders are Suncor Energy Inc. (SU), China Petroleum & Chemical Corp. (600028.SH), Nexen Inc. (NXY), Murphy Oil Corp. (MUR) and Mocal Energy Ltd. -By Edward Welsch, Dow Jones Newswires; 403-229-9095; edward.welsch@dowjones.com
