Towards interactive seismic imaging with curvelets

Towards interactive seismic imaging with curvelets Hervé Chauris (Ecole des Mines de Paris) and Truong Nguyen (Ecole des Mines de Paris) SUMMARY____________________________________________________________ We present a new methodology towards interactive seismic imaging. A first seismic image is obtained with a prestack depth migration code run in a reference velocity model. The objective is to efficiently derive what the migrated section would be in a perturbed velocity model. Instead of migrating the full input data in the second velocity model the reference migrated section is first decomposed in the curvelet domain. This provides coefficients associated to the representation of local plane waves
