A Comparison of Imaging Conditions for Wave-Equation Shot-Profile Migration

P272 A Comparison of Imaging Conditions for Wave- Equation Shot-Profile Migration J. Schleicher (Campinas State University (Unicamp)) J.C. Costa (UFPa) & A. Novais* (Unicamp) SUMMARY The application of an imaging condition in wave equation shot profile migration is important to provide illumination compensation and amplitude recovery. Particularly for true-amplitude wave-equation migration algorithms a stable imaging condition is essential to successfully recover the medium reflectivity. We study a set of image conditions with illumination compensation. The imaging conditions are evaluated by the quality of the output amplitudes and the artifacts produced. In numerical experiments using a vertically inhomogeneous velocity model the
