An acoustic system and method using well bore tube wave energy (103), converted to body wave energy (CODA) (106), at minor bore hole obstructions and casing rings (105), as point sources of seismic energy. Each casing ring obstruction or discontinuity position along the bore hole has an associated unique waveform source CODA that is measured for processing the body waves radiated into the earth formation surrounding the bore hole. A plurality of sensors (711), detects the radiated seismic signal after the signal transits the lithology formations. A time lapse profile is created and used for permanent monitoring of mineral resources and resource management.
