Accurate integration of flow simulation and seismic modeling is one of the
cornerstones of reliable time-lapse (4D) seismic monitoring. However, the
question which scales flow simulations need to resolve to accurately capture
reservoir changes during production and whether these scales are resolvable in
seismic data is an open one. The answer impacts computational costs and our
ability to predict reservoir changes from seismic observations. A sensitivity
study is performed to determined the main seismic features due to pressure and
saturation changes in an oil-gas reservoir during production. Numerical
experiments show that saturation fronts can be effectively tracked at
different flow and seismic resolution levels.
