The Syncrude oil sands project in northern Alberta has cut its production to zero for all of April following a fire last month, three market sources said on Monday. Syncrude, which is majority-owned by Suncor Energy, previously said shipments of synthetic crude were expected to restart at up to 50 percent of the plant’s 350,000 barrel-per-day capacity in mid-April.
