A system and method for determining a 4D difference from 4D seismic data including receiving a baseline seismic dataset and a monitor seismic dataset; identifying a 4D signal present in the monitor seismic dataset to create a 4D monitor dataset and a signal in the baseline seismic dataset which matches the monitor seismic dataset to create a baseline matching signal dataset; differencing the baseline matching signal dataset and the baseline seismic dataset to create a 4D baseline dataset; and differencing the 4D baseline dataset and the 4D monitor dataset to create a 4D difference dataset. In an embodiment, a multi-scale, multi-directional transform is used to identify the 4D signal present in the monitor seismic dataset and the signal in the baseline seismic dataset which matches the monitor seismic dataset. |
