Abstract
A method for the acquisition of seismic signals, in which at least two sources of the air gun type are placed within one or more vertical holes extending in the subsoil and in which one or more seismic sensors record the seismic propagated from said sources, that arrive at said sensors either directly, or by being reflected by the interfaces between the various layers of the subsoil, characterised in that the triggering of the various sources is adjusted so that the various seismic signals generated by said sources are simultaneously received by at least one reference sensor which is placed in a vertical hole which extends at the vicinity of the hole(s) which receive(s) the sources or which is one of said holes.
