Abstract

En fremgangsmåte for elektrisk undersøkelse av en vegg i et borehull i en geologisk formasjon innbefatter å injisere en strøm inn i formasjonen ved en første posisjon langs veggen, og å returnere strømmen ved en annen posisjon langs veggen, idet formasjonsstrømmen har en frekvens under omkring 100 kHz, å måle en spenning i formasjonen mellom en tredje posisjon og en fjerde posisjon langs veggen, hvor de tredje og fjerde posisjonene befinner seg mellom de første og andre posisjonene, og å bestemme en amplitude for en komponent av spenningen som er i fase med strømmen.
