Abstract

Prosessering av gammatallratenedbrytingskurver ved bruk av neurale nettverk. Minst enkelte av de illustrerte legemliggjøringene er fremgangsmåter som innbefatter å skaffe en gammatallsratenedbrytingskurve for hver av et flertall av gammadetektorer i et nukleært loggingsverktøy (gammatallsratenedbrytingskurvene blir registrert ved en bestemt borehullsdybde), å tilføre gammatallsratenedbrytingskurvene på inngangsnoder i et neuralt nettverk, å predikere ved hjelp av det neurale nettverket en geofysisk parameter for formasjonen som omgir borehullet, å gjenta skaffingen, tilføringen og predikeringen for et flertall av borehullsdybder, og å fremstille en kurvetegning for den geofysiske parameteren til formasjonen som en funksjon av borehullsdybden.
