Oil sands output at Syncrude expected to drop this year following an unplanned upgrader turnaround this spring.
Canadian Oil Sands, the company's largest shareholder, says it's reduced production targets to an average of 301,000 barrels per day, down from 309,000 bpd forecast in February.
The moves follows a small fire that knocked one of Syncrude's three cokers offline early in March.
Meanwhile, net income for Canadian was on par with the first quarter of 2011, with profits reaching $321 million.
