Abstract
The paper presents some examples of using migrational transformations according to the 2D and 3D seismic prospecting data from two areas from within the Saratov part of the Pricaspian Depression. Migration efficiency acquired from Kirchhoff’s integral algorithm was compared with that based on solving the wave equation. Using the migration based on the wave equation was shown to lead to better quality results in the geologic section intervals known for the problems with calculating raypaths in migration obtained from Kirchhoff’s algorithm.
