Reprocessing of digital seismic data by means of the FX - Decon method: example from Tyrrhenian sea

The most significant results from a reprocessing of old multichannel seismic data are presented and discussed. The reprocessing procedure was applied to the Apenninic tracts of the profiles MS-5, MS-6 and MS-7, digitally recorded in the Tyrrhenian Sea in 1969. The procedure has effectively attenuated both seismic noise and reverberations, and has also evidenced many seismic horizons originally masked by noise. The reprocessed sections, of which parts are illustrated, supply much more geologic information than the 1969 versions. As a consequence, this test clearly demonstrates that proper reutilization of old seismic surveys will be an important step for future exploration activities, not only in the planning but also for integrating new and old data.
