The extraction and upgrading process are energy-intensive, resulting in higher greenhouse gas emissions per barrel compared to conventional oil. The Nature of Alberta's Tar Sands Unlike conventional oil reserves found in porous rock formations, Alberta tar sand oil is highly viscous and does not flow naturally to the surface.

Key Differences in Extraction Surface Mining: Used for deposits less than 70 meters deep, recovering approximately 20% of the total resource. In this process, steam is injected underground to heat the bitumen, reducing its viscosity so it can be pumped to the surface, minimizing the surface footprint compared to mining.
The resource is so substantial that Canada holds the world's third-largest proven oil reserves, with the vast majority located in the Athabasca region, making it a cornerstone of the nation's energy strategy. The industry continues to invest in rail transport as a temporary solution, though it is less efficient and more hazardous than pipeline transport.
