Abstract

Foreliggende oppfinnelse tilveiebringer et brønnhullsverktøy som innbefatter et magnetometer og en kjernemagnetisk resonanssensor (NMR-sensor). Én eller flere kompenseringsmagneter er tilveiebrakt på verktøyet for å kansellere eller utligne virkningen av magnetfeltet til magnetene i NMR-sensoren på magnetometermålingene tatt under boring av et brønnhull. Kompenseringsmagnetene kan ha de samme magnetfeltkarakteristikkene som sensormagnetene og kan være laget av det samme materiale.
