Abstract
Et verktøy (1) benyttes for elektrisk undersøkelse av geologiske formasjoner (GF) som omgir et borehull (BH). Verktøyet (1) er omfattet i en streng med verktøy (TS). Verktøyet (1) omfatter en strøminjeksjonsseksjon (CIS) og en strømreturseksjon (CRS). Verktøystrengen (TS) omfatter minst én annen seksjon (OS1). Strøminjeksjonsseksjonen (CIS) er elektrisk dekoplet fra strømreturseksjonen (CRS). Strøminjeksjonsseksjonen (CIS) er elektrisk avkoplet fra den minst ene andre seksjonen (OS1) når strøminjeksjonsseksjonen (CIS) og den minst ene andre seksjonen (OS1) er nærliggende hverandre. Strømreturseksjonen (CRS) er elektrisk avkoplet fra den minst ene andre seksjonen (OS1) når strømreturseksjonen (CRS) og den minst ene andre seksjonen (OS1) er tilliggende hverandre.
