The invention relates to a process for two separate seismic crews to work in proximity to one another that would otherwise require expensive time sharing where one crew is a conventional seismic acquisition system and the other is a phase encoded seismic acquisition system. Typically, each recording system would receive seismic energy from the other that neither data set would be very useful. The invention primarily envisions some collaboration between the crews where each adjusts its sweeps to comprise a different time duration so that the energy the other crew's sources are distinguishable in the data set and easily eliminated therefrom. Distinctions may be further enhanced when the two crews use construct their sweeps so that each crew has a distinctly different start frequency and a distinctly different end frequency.
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.
