Surface mining is used for deposits located within 70 to 80 meters of the surface, where large trucks and shovels remove the material directly. This economic weight gives the sector considerable influence in energy policy and international trade negotiations, linking the fortunes of the regions involved to global oil prices.

Removing the overburden—the soil and rock covering the deposits—disrupts vast tracts of boreal forest and peatland. These resources consist of a mixture of sand, clay, water, and a dense, viscous form of crude oil known as bitumen.
Transportation and Refining Logistics Moving the raw material from the mine or wellhead to refineries requires a sophisticated logistics network. The result is a matrix where the bitumen coats the sand grains, creating a resource that is both abundant and challenging to access.

Because the bitumen is too viscous to flow through standard pipelines without dilution, it is often mixed with natural gas condensate or synthetic crude. Over time, this matter was buried under layers of sediment, where heat and pressure converted it into a heavy hydrocarbon blend.
