Abstract

Et første NMR-ekkotog samles inn med en enkelt TE. Et annet NMR-ekkotog samles inn med en første andel som har den samme TE og den annen andel som har en lengre TE. Når målinger foretas med en lav magnetfelt-gradient, kan behandling av de to ekkotog brukes til å fastlegge gass i formasjonen.
