Abstract

En fremgangsmåte for å bestemme minst første og andre avstand fra en innretning til minst et første lag og et andre lag i formasjonen hvorved minst enten det første eller det andre lag omfatter en elektromagnetisk induksjonsanomali, idet innretningen omfatter en sender for å overføre elektromagnetiske signaler gjennom formasjonen og en mottaker for å påvise responsene. I fremgangsmåten blir en innretning brakt inn i et borehull i formasjonen og et elektromagnetisk signal blir sendt ved å bruke senderen, idet enten åpenbar konduktivitet eller åpenbar resistivitet blir beregnet basert på en mottaker påvist respons og overvåket over tid. Første og andre avstand blir bestemt basert på observerte endringer av enten åpenbar konduktivitet eller åpenbar resistivitet.
