Three-dimensional seismic data using vertical cables was modeled and processed using equivalent offset migration (EOM), a pre-stack time migration method developed by CREWES.

The data was generated using 3-D ray tracing over a geological model obtained from seismic interpretation performed on a giant Brazilian offshore oil field. Velocity variations in three directions were obtained from 3-D seismic data acquired over the field.

The results show EOM is capable of handling a very large data set, but some noise created by the method is not attenuated after stacking.
