Abstract

Fremgangsmåter for oppnåelse av seismiske signaler som er representative for egenskaper ved jordens indre, innbefattende de trinn å oppnå akustiske nærfeltsignaler registrert i nærheten av en seismisk kilde (13), fjerne fra de akustiske nærfeltsignaler i det minste delvis signaler som representerer direkte ankomster fra den seismiske kilde (13), og bruke en øvrig del av de oppnådde signaler som estimat av et nullforskyvningsdatasett. Nullforskyvningsdatasettet kan så brukes til å interpolere data fra konvensjonell datafangstlokalitet, så som streamere (11), til lokaliteter nærmere kilden (13).
