Abstract

En fremgangsmåte og loggeanordning for generering av et retningssignal som er assosiert med responsen på elektromagnetisk energi for en formasjon i undergrunnen. Fremgangsmåten er nyttig for å utlede både strøkvinkelen for formasjonsgrensen og det relative fall. Det sanne fall og asimut kan beregnes fra informasjonen om det relative fall som er forbundet med borehullets orientering. Andre anvendelser av fremgangsmåten er også beskrevet.
