Abstract

Fremgangsmåte for seismisk prosessering for å eliminere multiple refleksjoner av marine seismiske data. Seismiske data migreres i tid eller i dybde (110), og dataene som således migreres behandles for å bestemme en approksimasjon av multiple refleksjoner som skal subtraheres fra seismiske data (120-160).
