In total, we hold over 2,000 mineral leases in Canada (mainly in Alberta and British Columbia). We produce and market natural gas, NGL, sulphur, synthetic crude oil and bitumen. Bitumen is a very heavy crude oil produced through conventional methods as well as through enhanced oil-recovery methods, such as those based on heating the reservoirs. Synthetic crude oil is produced by mining bitumen-saturated sands, extracting the bitumen from the sands, and transporting it to a processing facility where hydrogen is added to produce a wide range of feedstock for refineries.
