N2 - Combining 4D seismic data with fluid-flow modelling can improve hydrocarbon reservoir development and recovery efficiency. However, several challenges remain to achieve an overall consistency of geological, geophysical and reservoir engineering data. This thesis demonstrates that 4D seismic amplitudes can be more accurate than 4D seismic impedances for quantifying water saturation changes. Next, combining 4D seismic amplitude and production data to assess fluid-flow models demonstrated to improve consistency with multidisciplinary observations. Finally, broadband 4D seismic data better resolves reservoir changes in thin layers compared to conventional seismic, thereby reducing quantitative interpretation uncertainties associated with upscaling/downscaling effects.
