Abstract

Fremgangsmåte for dybdemigrasjon av seismiske data. Fremgangsmåten innbefatter pre-stakk tidsmigrasjon av de seismiske dataene for å danne en stakket, tidsmigrert avbildning. Den stakkede, tidsmigrerte avbildningen de-migreres, og post-stakk dybdemigrasjon utføres deretter på den de-migrerte avbildningen. I noen utførelser tar pre-stakk tidsmigrasjonen og demigrasjonen hensyn til stråleavbøyning i vertikalt transversale isotrope media.
