Oil Sands Reservoir Characterization in Athabasca, Canada

Reservoir characterization was conducted by combining geological and geophysical methods in the oil sands area, Athabasca,<br>Canada. For the production of bitumen from the reservoir 200 to 500 meters in depth, the Steam Assisted Gravity Drainage<br>(SAGD) method (Steam Injection EOR) has been adopted as bitumen is not movable at the original temperature. It is essential<br>to understanding the detailed reservoir distribution as bitumen is produced just from the vicinity of the producing wells by the<br>SAGD method.
