Abstract

Prestack migration is a successful tool for imaging complex structures and has recently become quite popular. Experience with prestack migration indicates that the quality of the image is very sensitive to the velocity model, and therefore prestack migration is also used as a velocity analysis tooI. The migrated image is usually obtained in an iterative procedure and the velocity model is updated between iterations. In other words, prestack migration and velocity estimation are related procedures. The velocity model is required so a good depth image can be obtained while the migration process itself is the tool for deriving the velocity models.
