The processes occurring in reservoir during its development are complex and interdependent. Corresponding changes of elastic parameters within the investigated interval influence seismic wavefield. The origin of such changes can be various and integrated. In order to split the integrated effects, it is necessary to attract multidisciplinary geoinformation. Each of the studied processes must be represented in the corresponding Earth model. This study demonstrates the influence, caused by reservoir development processes, on 4D seismic response. 4D seismic modeling was performed using the set of Earth models built for one of the offshore oilfields. As the result of the modeling, the optimal 4D acquisition technique was designed to register such changes of seismic wavefield.
