Abstract

The method involves producing a signal sample (42) with a given, temporally variable frequency spectrum by an acoustic event. The signal sample is radiated as oscillation event into a borehole (10). The signals coming at the earth surface (11) from the borehole are caught to be analyzed, and from the caught signals, the analysis oscillation events are filtered and correlate the radiated signal sample. An independent claim is included for a device for execution of the method.
