The migration process removes the effect of wave propagation from the recorded seismic data. As an application of this operator, seismic events will move towards their correct positions, diffractions have to collapse and dipping events have to move to their correct subsurface locations.
In this article different algorithms of the migration operator have been considered and applied on real data. Based on the results, the Kirchhoff migration, which is the most common algorithm, was chosen and used to apply for pre-stack depth migration on real data. The data obtained from an oil field in the southern part of Iran. Subsequently the obtained results were compared
