We have modeled the warm-up phase of a SAGD project using a coupled reservoir simulator and stress model. We matched the injection pressure by adjusting the reservoir permeability. A fair match between data and model was obtained. Micro-seismic monitoring indicated localized injection at the toe, which was used in the model. Also, the seismic signature indicated strike slip and possibly overthrust fault slippage or casing failure as cause of the seismicity. This confirms the reservoir and stress model used in the interpretation. While most of the steam was injected at the toe, the uplift was largest at the heel of the well. This can be best explained by reservoir heterogeneity, which implies that surface heave measured with tiltmeters can best be interpreted using a geomechanical model. The matched coupled model can be used for optimizing the completion and injection process.
