This paper presents an implementation of 3D pre-stack Kirchhoff depth migration of SWD data. Practical solutions are proposed to equalize the illumination of the migration target, to reduce the migration artefacts and to control the alias. The procedure is tested on a real data set, kindly furnished by ENI-AGIP Division and OGS. The result is compared with the seismic section obtained from surface reflection data. The overall features are similar.

Abstract
This paper presents an implementation of 3D pre-stack Kirchhoff depth migration of SWD data. Practical solutions are proposed to equalize the illumination of the migration target, to reduce the migration artefacts and to control the alias. The procedure is tested on a real data set, kindly furnished by ENI-AGIP Division and OGS. The result is compared with the seismic section obtained from surface reflection data. The overall features are similar.File in questo prodotto:
