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. 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.
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. This method is utilized when the oil sand is found within 70 meters of the surface, making it economically viable to remove the earth above.
