5 Biggest Oil Producers in the World

4. Canada

Total Oil Production: 5,576,000 b/d

While Canada produces more oil than required to meet its domestic refining needs, some refineries import crude oil for a variety of reasons, such as higher transportation costs, limited pipeline access, and the inability of refineries to process WCSB heavy crude oil. 

The Irving Oil Refinery at St. John, New Brunswick, is the largest oil refinery in Canada. With a capacity of 320,000 b/d, the refinery supports 2,440 jobs through its supply chain and accounts for about half the dollar value of the province’s exports.
