Abstract

Det er beskrevet fremgangsmåter og anordninger for å detektere og overvåke borehullseffekten i undergrunnsmålinger. Toroidale sensorkonfigurasjoner (12) tar hensyn til de uønskede, aksiale, elektriske strømmer som flyter langs borehullet når antennene (17, 19) med skråstilte eller transversale akser blir brukt til å ta elektromagnetiske målinger. Utførelsesformer benytter strømmer målt langs instrumentet for å bestemme kvaliteten av målte logger, borehullets dimensjon og instrumentets posisjon eller orientering inne i borehullet.
