| dc.description.abstract | In this thesis, I present the results of a new approach to pre-stack Kirchoff depth migration using the Kirchoff algorithm and the Fresnel aperture features in order to improve the signal-to-noise ratio of the seismic data in depth imaging. Another advantage of this method is that it requires no additionnal measurments compared to the traditionnal PSDM. Indeed, the Fresnel apertures are picked interactively, in a way that is similar to velocity picking, and thereafter used during the migration process. This tecnique was tested on both synthetic and field data. | nor |
