Prestack Kirchhoff migration
Conventional NMO + Stack processing does not work well in structurally complex areas. Especially in the case of converted waves, true CCP stacking is not always achievable in such areas. Therefore, prestack migration is a preferred alternative. In this paper, some aspects of prestack Kirchhoff migration are reviewed and test results for both P-P data and P-SV data are presented. It turns out that the Kirchhoff algorithm migrates both P-P data and P-SV data very accurately.
