A method for determining the optimum positioning of source-receiver pairs capable of acquiring seismic data comprising: - a first step of identifying a zone of interest in a subsoil having been the subject of an earlier seismic acquisition by means of source-receiver pairs whose exact location is known, and used to obtain an image of the subsoil; - a second step of obtaining seismic data acquired during the earlier seismic acquisition corresponding to said zone of interest during a time of interest; - a third step of applying a partial or total demigration of said seismic data corresponding to said zone of interest, in order to determine the positions of each source-receiver pair (31, 34) having contributed, in the image of said subsurface, to the image of said zone of interest during said time of interest; - a fourth step of obtaining unprocessed traces (41, 42, 43, 44, 45) of the seismic data acquired during the earlier seismic acquisition for said positions of the source-receiver pairs (31, 34); - a fifth step of selecting at least one optimal unprocessed trace (43, 44) from said unprocessed traces, the at least one optimal unprocessed trace (43, 44) being the one(s) having a higher signal-to-noise ratio than the other unprocessed traces, having contributed to the identification of a change in the zone of interest; - a sixth step of determining the optimal positions of the source-receiver pairs (31, 34) corresponding to said at least one optimal unprocessed trace (43, 44); - a seventh step of placing source-receiver pairs (31, 34) at said optimal positions; - an eighth step of acquiring new seismic data at said optimal positions. - a first step of identifying a zone of interest in a subsoil having been the subject of an earlier seismic acquisition by means of source-receiver pairs whose exact location is known, and used to obtain an image of the subsoil; - a second step of obtaining seismic data acquired during the earlier seismic acquisition corresponding to said zone of interest during a time of interest; - a third step of applying a partial or total demigration of said seismic data corresponding to said zone of interest, in order to determine the positions of each source-receiver pair (31, 34) having contributed, in the image of said subsurface, to the image of said zone of interest during said time of interest; - a fourth step of obtaining unprocessed traces (41, 42, 43, 44, 45) of the seismic data acquired during the earlier seismic acquisition for said positions of the source-receiver pairs (31, 34); - a fifth step of selecting at least one optimal unprocessed trace (43, 44) from said unprocessed traces, the at least one optimal unprocessed trace (43, 44) being the one(s) having a higher signal-to-noise ratio than the other unprocessed traces, having contributed to the identification of a change in the zone of interest; - a sixth step of determining the optimal positions of the source-receiver pairs (31, 34) corresponding to said at least one optimal unprocessed trace (43, 44); - a seventh step of placing source-receiver pairs (31, 34) at said optimal positions; - an eighth step of acquiring new seismic data at said optimal positions.
