Summary:
Modification of the application methods for duplex wave migration (DWM) has enabled us to obtain seismic images of sub-vertical boundaries which are formed by the waves having the fixed incidence angle ranges (partial DWM cubes). It allows the AVO analysis for sub-vertical objects (AVO-DWM) and on that basis the classification of the vertical boundaries and their properties. The role of the full-wave modeling for calculation of corrections needed for the creation of amplitude corrected AVO-DWM curves on vertical boundaries is shown. Example of the AVO - DWM on a real 3D data set is demonstrated.
