%X Internal multiple removal is a great challenge in seismic processing, and there is no successful approach to remove internal multiple. We present a method to remove internal multiple by discriminating primary reflections from multiple reflections during the migration process. Both the take-off and incidence angles are computed from the data so that rays can be traced from both the source and the receiver positions. An Eikonal equation is used for estimating the travel time table. Numerical results for a SEG/EAGE salt model show that the wavepath migration can clearly resolve the true interfaces and effectively remove multiple. Field data results show that the method can effectively remove the migration artifacts generated by internal multiples
