Abstract

La présente invention concerne un procédé qui permet à deux équipes sismiques de travailler à proximité l'une de l'autre, ce qui impliquerait autrement un partage du temps coûteux avec une équipe disposant d'un système d'acquisition sismique classique et une équipe disposant d'un système d'acquisition sismique à codage de phase. Généralement, chaque système d'enregistrement reçoit de l'autre système, l'énergie sismique d'un ensemble de données qui ne sont pas très utiles. La présente invention envisage une certaine collaboration entre les équipes dans laquelle chaque équipe ajuste ses balayages pour comprendre une plage de temps différente de sorte que l'énergie des sources de l'autre équipe soit repérable dans l'ensemble de données et facilement éliminée de ce dernier. Les différences peuvent être renforcées plus encore lorsque les deux équipes utilisent leurs balayages de sorte que chaque équipe ait une fréquence de démarrage différente et une fréquence de fin visiblement différente.
