Abstract
En fremgangsmåte for å rekonstruere (13 8) et valgt bølgefelt i en angitt felles midtpunkt og offset - posisjon (132) fra et sett av prestakk seismiske datatraser (126).Fremgangsmåten bruker virkelige datatraser fra andre felles midtpunkt og offset-posisjoner til å rekonstruere det valgte bølgefelt i den angitte rekonstruksjonsposisjonen. Fremgangsmåten brukes til å rekonstruere ethvert valgt bølge-felt, inkludert både primærrefleksjonsbølgefelt og sekundære bølgefelt slik som bølgefelt fra vann-bunnsmultipler, og kan bruks med både 2-D og 3-D seismiske data. Hvis det rekonstruerte bølgefelt er et sekundært bølgefelt, kan det subtraheres fra de prestakk seismisk datatraser for å eliminere inter-ferens mellom bølgefelt. Fremgangsmåten kan også brukes til å rekonstruere data fra manglende skudd for å unngå problemer med romlig overlapping (alia-sing) i andre dataprosesseringsoperasjoner.
