Abstract
In the context of velocity estimation, we investigate the differential waveform inversion method. The approach is formulated in the data domain and consists of two main steps. First, for a given shot, we derive the optimal reflectivity section. From the result, we then compute the next shot gather. The new formulation measures the differences between the predicted shot and the observed shot at the nextposition. The main interest of the Differential Waveform Inversion strategy resides in the possibility to take into account surface-related multiples. The key point is the iterative migration.
