Abstract

In the case where subsurface structures are complex, it is recognized that correct depth imaging should be carried out with prestack data. When 3-D data are available, the implementation of a 3-D prestack depth migration is required. The quality of depth images heavily depends on the accuracy of the interval velocity function. Taking into account the computational effort associated with the migration, the problem of defining the interval velocity model must be solved prior to the execution of the migration task. Experience gained from 2-D work shows that structural imaging can be effectively used as a tool for interval velocity analysis in complex areas. This study tries to imp lement similar procedure in the 3-D case.
