10 Biggest Canadian Oil & Gas Companies

The oil and gas industry in Canada, as in other regions, is generally divided into three main segments: upstream, midstream, and downstream. Upstream companies engage in the exploration and production (E&P) of crude oil and natural gas. This entails searching for oil below the ground and drilling wells in order to access those reserves.

In some cases, such as in the Canadian oil sands, companies either mine for crude bitumen, a dense, viscous form of crude oil, or use in-situ recovery processes that inject steam and chemicals deep beneath the ground to separate the bitumen from the sand and pump it to the surface.

Both methods are relatively expensive compared to traditional well-extraction methods, making the break-even price of oil for oil-sand producers much higher than for more traditional producers.

Midstream companies are engaged in the storage and transportation of oil and gas, while downstream companies refine and sell finished petroleum products.
