ABSTRACT:
A method for generating a three dimensional velocity model makes use of two dimensional depth images, which are the result of two dimensional pre-stack depth migration, and corrects the out of plane distortion by ray tracing through a three dimensional model. The three dimensional model boundaries are iterated until the three dimensional effects are minimized. The final model can be used for a final three dimensional pre-stack depth migration, or as a three dimensional interpretation of all the two dimensional depth migration results.
