Abstract

Oppfinnelsen angår en transmittersløyfekonfigurasjon som anvendes til elektromagnetiske geofysiske nedihulls- og jordundersøkelser. Sløyfetråden er spredt ut på jordoverflaten på en slik måte at den danner flere seriekoblede undersløyfer. Hver undersløyfe kan være anbrakt ved siden av hverandre eller være atskilt med en fast avstand. Hver undergruppes bidrag til det primære elektromagnetiske felt forbedres i intensitet og vektorretning for å aktivere begravde geologiske ledere på en mer effektiv måte. Denne utformingen genererer et sterkt subhorisontalt primært felt i en i-sløyfe-sone av den globale sløyfe. En hvilken som helst subvertikal leder som er skjult under denne i-sløyfe-sonen, vil være maksimumskoblet og vil generere et sekundært elektromagnetisk felt som er detekterbart med en mottakeranordning. Denne oppfinnelsen innbefatter muligheten av å anvende en kombinasjon av flere sløyfepar.
