o 3D wave-equation based multiple modeling to fully benefit from the available rich subsurface reflectivity representation. Along with this, an innovative and specific implementation of wave equation modelling enabled the construction of diffracted multiples “only” models. These separated models were fed into a multi-model adaptive subtraction using AVO-driven primary models as a constraint to preserve primary information (especially low frequencies). The ensemble lead to improved demultiple results.
