For deeper resources, in-situ techniques such as Steam-Assisted Gravity Drainage (SAGD) are employed, involving the injection of steam to heat the bitumen and allow it to flow to a production well. The oil sands were formed millions of years ago when organic matter settled in ancient riverbeds and deltas.

Once transported to refineries, usually located far from the extraction site, the material undergoes an upgrading process to remove impurities and increase its value, integrating it into the broader fuel supply chain. Because the bitumen is too viscous to flow through standard pipelines without dilution, it is often mixed with natural gas condensate or synthetic crude.
Economic Significance and Global Market Role Despite the controversies, the economic impact of these resources is undeniable, particularly for Canada, which holds the third-largest proven oil reserves globally. Surface mining is used for deposits located within 70 to 80 meters of the surface, where large trucks and shovels remove the material directly.

Removing the overburden—the soil and rock covering the deposits—disrupts vast tracts of boreal forest and peatland. The result is a matrix where the bitumen coats the sand grains, creating a resource that is both abundant and challenging to access.
