P068 AUTOMATIC AND CONTINUOUS IMAGE GATHER ANALYSIS AFTER PRE-STACK DEPTH MIGRATION LAURENT LEMAISTRE CHRISTIAN HANITZSCH and ANNE LEHEC Introduction 1 Pre-stack depth migration (Pre-SDM) becomes a conventional tool in seismic processing. Pre- SDM is used mainly when time processing assumptions are no longer valid for example in structured zones with strong velocity variations. As the quality of Pre-SDM result is very sensitive to the accuracy of the input velocity model the control and the validation (QC) of the input velocity model become essential in the Pre-SDM processing sequence. We present an innovative and fast method which allows the processing geophysicist
