The migrating including generating an initial model of velocities below the salt layer. The initial model is scaled by a plurality of scale factors at at least one image position. At least one of the plurality of scale factors for which a depth migrated image below the salt layer is optimum is selected as the scale factor.1/6 GENERATE INITIAL VELOCITY MODEL TO BASE OF 1 IMAGE CONVENTIONAL DEPTH 12 MIGRATION TO TOP OF SALT LAYER USE KNOWN SALT VELOCITY TO DEPTH 14 MIGRATE TO BASE OF SALT LAYER SCALE ALL VELOCITIES BELOW SALT BY PLURALITY 16 OF SCALE FACTORS IN SELECTED RANGE PERFORM SCALING ON COMMON IMAGE GATHERS AT PLURALITY 18 OF POSITIONS PROXIMATE IMAGE OUTPUT LOCATION SELECT SCALE FACTOR THAT PRODUCES SHARPEST MIGRATED IMAGE FIG. 1
