Abstract

En loggeenhet for anvendelse i et brønnhull utformet i en jordformasjon. Enheten omfatter et foringsrør egnet til å senkes gjennom brønnhullet og til å anordnes i en valgt del av dette, og en NMR loggeanordning omfat-tende magnetiseringsanordninger for å indusere et magnetfelt i en valgt sone av jordformasjonen, anten-neanordning for å sende radiofrekvens RF signaler inn i den valgte sone og for å motta respons RF signaler fra den valgte sone, og datasamlingsanordning for å samle data som representerer respons RF signalene, hvor datasamlingsanordningen er fjernbart anordnet i det indre av foringsrøret. Anordningen for å indusere magnetfeltet omfatter en magnetisert seksjon av foringsrøret.
