Abstract

Den presenterte fremgangsmåten tar hensyn til 3D effekter ved ekkofjerning i marine seismiske data. Fremgangsmåten beror på å ha annen ordens romderiverte i krysslinjeretningen tilgjengelig. Den annen ordens krysslinjederiverte kan estimeres direkte eller ved indirekte målinger av andre bølgefeltstørrelser og ved åbruke bølgeligningsteknikker til å beregne det ønskede leddet. Fremgangsmåten anvender fortrinnsvis en multikomponentstreamer slept i nærheten av havoverflaten, en dobbelstreamerkonfigurasjon nær havoverflaten eller en konfigurasjon av tre streamere som er atskilt enten vertikalt eller horisontalt til å estimere den annen ordens vertikalderiverte av trykk.
