Suncor Energy reporting a 10% spike in four quarter profits.
Canada's largest oil and gas company earned $1.4 billion in the final quarter of 2011, up from $1.3 billion in the same time frame last year.
The increase came as a result of higher crude prices.
Oil sands output averaged 326,500 barrels per day in Q4, a slight increase over 2010.
Suncor has also restarted production at three of its five fields in Libya, while its operations in Syria, remain suspended.
