Abstract
Anordningen omfatter en sender/mottaker-spole (5) som kan beveges i brønnen og en anordning (8) for å generere et periodisk eksiteringssignal som skaper en overspenning i sender/mottaker-spolen. Variasjonen av spolens overspenningsfaktor blir bestemt ved hjelp av en måleanordning (9) og analysert ved hjelp av en behandlingsanordning (10) for å tilveiebringe informasjon om verdien av konduktiviteten i den formasjon som befinner seg omkring brønnen.
