HOUSTON, Jan. 7 -- Suncor Energy Inc., Calgary, is investigating a Jan. 4 fire at its Fort McMurray, Alta., oil sands facility that cut production to 110,000 b/d from 225,000 b/d.
It was not immediately known when full production might resume.
The fire was extinguished the same day it started at one of the facility's two upgraders, which convert bitumen into refinery feedstock and diesel. The blaze primarily affected a coker fractionator. Although 250 employees work in the immediate area, only minor injuries related to cold weather were reported.
