Two primary extraction methods exist, dictated by the depth of the deposit. For shallow deposits, surface mining is employed, where massive shovels remove the overburden and scoop up the oil sands.

Surface Mining: The Visible Impact Surface mining operations create a distinct landscape in the boreal forest. These operations have the largest physical footprint of any oil extraction method, transforming dense forest into open-pit mines that can be seen from space.
In-Situ Extraction: The Subterranean Approach When oil sands are buried too deeply for mining, the industry turns to in-situ methods, which account for the majority of current production. Economic Significance and Infrastructure The oil sands industry is a cornerstone of Alberta's economy, contributing billions to the provincial GDP and providing thousands of high-paying jobs.
