... is a commercially proven technology for Athabasca reservoirs. It produces high oil rates and high ultimate recoveries. Injecting a solvent with the steam can reduce required steam rates and/or improve oil rates and recovery. Oil viscosity is reduced both thermally and by solvent dissolution. A scaled model...

... of heavy oil within the Faja reservoirs. The process is based on a repetitive pattern using horizontal wells acting alternatively as oil producers and steam injectors. The recovery mechanism is a combination of horizontal steam flooding between wells and cyclic steam stimulation of each of the horizontal...

... Abstract The design and analysis of well tests for heavy oil producers is complicated due to both the mechanics of artificial lift and the properties of the fluids produced. Traditional analysis methods and assumptions used for light oils and flowing wells are only practically applicable...
