Abstract

Une source sismique marine verticale décalée contient des ensembles supérieur et inférieur (10, 11) d'émetteurs d'énergie sismique (S11, S12; S21, S22). L'ensemble supérieur (10) est déplacé horizontalement par rapport à l'ensemble inférieur (11). La source est utilisée dans un agencement d'étude sismique marine comportant des moyens permettant de déplacer la source ainsi qu'au moins un récepteur sismique. Lors de l'utilisation, la source est déplacée à travers l'eau dans un sens parallèle au sens dans lequel les deux ensembles sont déplacés. Les ensembles (10, 11) sont déclenchés de manière séquentielle et le retard de temps entre le déclenchement de l'ensemble déclenché en premier et le déclenchement de l'ensemble déclenché en second est choisi de telle manière que chaque émetteur sismique se trouvant dans un ensemble soit déclenché aux mêmes coordonnées X et Y que les émetteurs correspondants se trouvant dans l'autre ensemble. Les champs d'ondes sismiques générés par le déclenchement des deux ensembles sont ainsi générés aux mêmes coordonnées X et Y mais à des profondeurs différentes. Les données sismiques enregistrées par le ou les récepteurs, suite au déclenchement du premier ensemble, peuvent être utilisées pour éliminer le dédoublement des données sismiques acquises après le déclenchement du second ensemble ou vice versa, éliminant ou réduisant ainsi l'effet de réflexions et de réverbérations fantômes du côté de la source.
