Abstract

En fasefeil i målinger gjort av et resistivitetsloggeverktøy blir estimert ved å posisjonere verktøyet over en elektrisk ledende overflate. Avvik fra 90° for den målte fasedifferansen mellom senderen og mottageren fra gir fasefeilen i elektronikken. Det er lagt vekt på at dette sammendraget er skaffet tilveie for å stemme med de reglene som krever at et sammendrag som tillater en søker eller annen leser raskt å sette seg inn i innholdet i den tekniske avsløringen. Det er utgitt med den forståelse at det ikke vil bli brukt til å tolke eller begrense rekkevidden eller meningen med kravene.
