Reflected-transmitted non-converted and converted seismic waves as used for seismic imaging which is not limited by the angle of inclination of the seismic interfaces. These wave signals are recorded at the surface and are later used to obtain seismic imaging of geological discontinuities and the physical properties of the medium. Known duplex waves are used with transmitted waves for obtaining seismic images from much wider angles, ranging from horizontal to vertical. Two types of migration procedures are used: the first one being based on migration of transmitted compressional and converted duplex waves, and the second one being based on the joint migration of two interrelated fields, such as interferometric principles; for example, the first field of primary waves corresponding to the one time reflected monotypic compressional (non-converted) type of waves and a second wavefield corresponding to secondary waves of more complex origin, such as reflected waves and converted waves.
L'invention concerne des ondes sismiques réfléchies-transmises non converties et converties telles qu'utilisées pour une imagerie sismique qui n'est pas limitée par l'angle d'inclinaison des interfaces sismiques. Ces signaux d'onde sont enregistrés à la surface puis utilisés pour obtenir une imagerie sismique des discontinuités géologiques et des propriétés physiques du milieu. Des ondes duplex connues sont utilisées avec des ondes transmises pour obtenir des images sismiques à partir d'angles bien plus grands, allant de l'horizontale à la verticale. Deux types de procédures de migration sont utilisés : la première se base sur la migration des ondes duplex de compression et converties transmises; et la seconde procédure se base sur la migration commune de deux champs interdépendants, tels que des principes interférométriques, par exemple, le premier champ d'ondes primaires correspond au type d'ondes (non converties) de compression monotype réfléchies une seule fois et un second champ d'ondes correspond aux ondes secondaires d'origine plus complexe, telles que des ondes réfléchies et des ondes converties.
