Summary:
An integrated study was performed to monitor the steam front in a heavy oil reservoir in Kuwait. Simultaneously processing VSP data provided important attributes for calibrating 4D surface seismic processing, inversion and reservoir characterization. The imaged data sets of both VSP and surface seismic data were inverted to take advantage of the fine resolution of VSP and wide coverage of surface seismic data. A calibrated viscoelastic rock physics model was built based on the heavy oil properties. This model was used to invert for temperature cubes at the time of base and monitor surveys. The seismic-driven temperature maps revealed the size and orientations of the steam anomalies that were well-correlated to reservoir engineering data. This study proved the value of the land time-lapse seismic for updating the reservoir engineer’s models.
