Canada holds the largest known reserves of tar and oil sands in the world, primarily in the Athabasca region. For deeper resources, in-situ techniques are used, which involve injecting steam underground to heat the bitumen and allow it to flow to the surface without disturbing the land above.
In-Situ Recovery Steam Solvent Techniques for Tar and Oil Sands
The term "tar" is a misnomer that harks back to the historical byproducts of coal processing, whereas the modern resource is a complex hydrocarbon mixture that requires sophisticated refining to become usable fuel. Unlike conventional light crude that flows freely, this resource is a dense combination of sand, clay, water, and a thick hydrocarbon called bitumen.
Defining the Resource: Tar vs. In-Situ Recovery: Used for deeper deposits, utilizing steam or solvents to reduce viscosity and pump the resource to the surface.
In-Situ Recovery Steam Solvent Techniques for Oil Sands
Surface Mining: Used for deposits less than 75 meters deep, involving excavation and truck transport. The substance is technically bitumen, a highly viscous form of petroleum, which is mined from vast deposits found primarily in Canada, Venezuela, and the Orinoco Belt.
