Abstract
Migration-based AVO analysis is known to be highly sensitive to the vetocity macro model [3,4,12]. In case of inaccurate velocity macro model, common image gathers are badly focused and the comparison of near and far depth migrated images requires residual depth corrections for flattening the events [11].
