Subsalt Migration Velocity Analysis with the Common Image Cube Approach

K. Mansoor1, O. Hermant1, H. Baudon1, S. Warzocha1, and M. Van De Rijzen2



Accurate subsalt imaging requires both high fidelity imaging algorithms and accurate velocity models. One-way and two-way wave equation migration methods have evolved at a faster pace than the migration velocity analysis (MVA) methods used to build and update the velocity models. Ray-based tomography is still the basis of most commonly-used MVA methods. This updating method can be both incompatible with wave equation imaging algorithms and inaccurate in a complex velocity environment.
