Abstract

Fremgangsmåte for å undertrykke støy i dataene fra den elektromagnetiske undersøkelsen med den styrte seismikkilden, basert på frekvensinnholdet i støyen (51) som dataene inneholder. Oppfinnelsen tar hensyn til at noen datavariasjoner på tvers av bingene ikke kan henføres til variasjoner i spesifikk motstand i jorden. Denne variasjonen over bingene utgjør en modell av støy i slike undersøkelser, og oppfinnelsen reduserer støy som følger denne modellen.
