Due to a high quality oil sands reservoir with critical cap rock spread over the area, Connacher is able to utilize the proven technology of steam-assisted gravity drainage (SAGD) for its projects to date. This allows us to extract bitumen from oil sands formations, which are located approximately 475 meters below the surface of our leases. Connacher is not engaged in oil sands mining. SAGD is demonstrated in the diagram below.
The term in-situ refers to the process whereby bitumen is separated from the sands while still underground in the oil sands original location. This stands in contrast to oil sands mining operations, where the separation takes place after the oil sands are moved from their original location.
