Time-lapse seismic is now recognized as a powerful tool for monitoring CO2 floods and provides valuable information on the advance of the flood, the area which has been swept, and in many cases identifies areas that are unswept or poorly swept. However, these programs typically include just a baseline and one or a limited number of monitor surveys recorded over a relatively long time period. As such, they do not yield the full value of which they are capable. Recording a multiplicity of monitor surveys at fine time intervals can provide significantly more complete characterization of the flood, enabling us to monitor the evolution of the flood in a true time-lapse sense.
