Beam Depth Migration For Imaging Of Complex Geology

Kirchhoff migration has traditionally been the leading implementation for application of depth<br>migration to seismic data. There are many reasons for this, such as efficiency, ability to image steep and even<br>overhanging dips, and flexibility. In most parts of the world Kirchhoff migration produces images that are as<br>good as, or better, than the more expensive implementations using downward continuation algorithms.<br>However, the limitations of Kirchhoff migration are well known and its inability to image more than a single<br>arrival is the most damaging. Downward continuation algorithms, on the other hand, handle all arrivals but<br>their inability to image steep dips is a severe limitation.
