Here we present a technique for performing residual move-out correction of
all CRP gathers output from the final iteration of a 3-D pre-stack depth mi
gration. We Will show the effectiveness of this approach for improving the
imaging of seismic events not explicitly described in the velocity-depth mo
del, and for compensating for residual move-out resulting from small errors
in the velocity-depth model. The results will be demonstrated on North Sea
3-D pre-stack depth migrated data examples.
