Sensitivity and Economic Analysis of Solvent Assisted SAGD Considering Geomechanics

Solvent Assisted SAGD (SA-SAGD) has the potential to lower steam oil ratio and increase oil production rate compared to SAGD alone and is usually operated close to reservoir pressure. Three Key design parameters are solvent type, injected solvent concentration and solvent retention in situ. However, the impact of oil sands Geomechanics, i.e. in situ dilation due to pressurization and thermal stresses, on the design parameters and on the economy of the process in general, has received less attention.
