Abstract

En fremgangsmåte for måling av en resistivitet i en undergrunnsformasjon (24a, b) som inkluderer kontinuerlig sending av et signal ved en første fundamental frekvens med full effekt over en første tidsperiode innenfor et enkelt tidsvindu, hvilket forårsaker at elektromagnetisk energi forplanter seg i undergrunnsformasjonene (24a, b), kontinuerlig sending av signalet ved en annen fundamental frekvens ved full effekt over en annen tidsperiode innenfor det enkelte tidsvindu, hvilket forårsaker at elektromagnetisk energi forplanter seg i undergrunnsformasjonene (24a, b), måling av variasjoner i den elektromagnetiske energi som har forplantet seg gjennom undergrunnsformasjonene (24a, b) ved mottakere (20) ved den første og den annen fundamentale frekvens, og bestemmelse av resistiviteten i undergrunnsformasjonene (24a, b) ved anvendelse av målingene av variasjonene i elektromagnetisk energi ved mottakerne (20).
