Abstract
We present examples of 4D time-shifts obtained with offset and angle sub-stacks of seismic data acquired in deep (Gulf of Mexico) and shallow water (North Sea) marine environments. We compare the observations with two proposed rock-physics models using different linear relationships between the velocity change and the strain field induced by reservoir compaction. The model involving only vertical strain component predicts a similar time-shift with offset behavior as that observed from the data. We do not observe a strong decrease of time-shifts with offset as reported in previous publications.
