In order to successfully use time-lapse seismic data to monitor dynamic effects occurring in carbonate reservoirs, the development and adaptation of tools for seismic attribute analysis are necessary. In particular, since carbonate reservoirs tend to compact and subside under production, it is desirable to estimate this effect from the time-lapse seismic data and to separate this response from fluid effects that influence the seismic response. Furthermore, it is very important to identify and classify the fault network of carbonate reservoirs in detail due to its strong influence on the fluid flow. New tools are presented that address these problems. These tools are applied to seismic time-lapse data from the Ekofisk Field to demonstrate how compaction distributions can be quantified in 3D and how migration paths of injected water along fault and fracture zones can be identified.
