Abstract
2D prestack depth S-G migration with focusing analysis is today one of the most widespread technique used in industry to solve the imaging problem in complex areas . This technique aims at determining the best migration velocity macro-model by focusing optimization. The procedure is iterative and at each step the macro-model should be improved .
