Conclusion

Real data offer an opportunity to test our imaging techniques further. Common-azimuth migration (CAM) is an attractive method for seismic imaging in complex media and it remains a subject for further research. Its computational cost and its high resolution in depth slices, illustrated in this particular example, can make it an attractive alternative to widespread Kirchhoff methods. Both approaches show different specificities and are equivalently valuable in our seismic imaging toolbox.
