... Abstract SAGD has been proven to be a commercially viable method to extract bitumen from oil sands reservoirs in Western Canada. To understand the influences of steam injection on reservoir and surrounding rocks and potential impacts of surface deformation on the environment, instrumentations...

... Abstract Thermal recovery methods (such as steam injection) are recent remarkable technologies to recover bitumen from oil sands. The injected steam contacts the oil sand and forms an interface. The steam changes to water transferring its heat to bitumen across this interface. The heated...

... Abstract Water availability and water storage will have impacts on oil sands development as surface-mined production increases. As a result, several technologies designed to increase the percentage of recycle water are being evaluated. One such option is the use of centrifuges to produce dry...

... Abstract The volume of heavy oil and bitumen in the oil sands deposits in Western Canada is similar to that of conventional crude oil in the Middle East. This resource is immense but is difficult and energy intensive to extract because the viscosity of the oil is high, typically over 100,000...

... Abstract The Burnt Lake Oil Sand Lease is located about 300 km northeast of Edmonton. The lease is estimated to contain 330 million m 3 of bitumen in place in the Clearwater oil sands formation. Cold production was tested in the lease to recovery 11–12 °API crude bitumen between 1990 and 1993...

... convectively to the outer edges of a steam depletion chamber. At the edges of the chamber, the steam releases its latent heat to the cool oil sand and raises its temperature leading to a reduction of the oil's viscosity to between 2 and 20 cP. The oil flows under the action of gravity to a horizontal...

... Abstract The role of natural surfactants in bitumen extraction from oil sands has been extensively researched, but these studies have focused primarily on surfactants that are soluble in the water phase. Recent work at CETC-Devon has shown strong correlations between bitumen weathering...
