Example of seismic time-lapse velocity sag effects. The presence of steam (or other fluid and pressure changes) can change the seismic velocity of the fluid-filled rock enough to result in differences in arrival time for rays passing through the steamed zone. This map shows the change in travel time between two layers encompassing the steamed interval, indicating the movement of steam between two time-lapse seismic experiments. The greatest changes have taken place in the circled areas (from Eastwood et al.78).
