Abstract

En seismisk prosesserings-fremgangsmåte hvor eikonalligningen løses for å bestem-me gangtidene for en lydbølge mellom en seismisk kilde og et punkt under bakken, hvor fremgangsmåten kjennetegnes ved at for å løse eikonalligningen utføres ekstrapolerings-prosessering på den hastighets-variabelen som er lik forhol-det mellom avstanden mellom den seismiske kilden og det underjordiske punket delt på utbredelsestiden mellom kilden og punktet.
