Abstract
Fremgangsmåte og system for fremskaffelse av en vertikal seismisk profil (VSP) hvorved avstands- intervallene mellom enheter, enten seismiske kilder eller mottakere, i et borehull esker eksponensielt ettersom avstanden fra overflaten øker, samtidig som avstandsintervallet mellom enheter, enten seismiske kilder eller mottakere, langs overflaten ¿ av bakken avtar eksponensielt ettersom distansen i fra overflatekrysningen for brennborehullet øker. Ved en foretrukken utførelsesform for den foreligg- ende oppfinnelse, blir den felles dybdepunkt (CDP) folding av data som er innsamlet, i det vesentlige utflatet over den reflektor som undersøkes.
