Geomechanical modeling for InSAR-derived surface deformation at steam-injection oil sand fields

► Reservoir volume change was estimated using geomechanical inversion. ► InSAR-derived surface deformation is used for the inversion. ► The two-step inversion technique is based on the Okada model. ► Genetic algorithm inversion is used to estimate dislocation plane depth and geometry. ► Reservoir volume change was calculated using a least-squares inversion.
