Abstract

En fremgangsmåte for å bestemme viskositet, ?, til et nedihullsfluid, påkaller utførelse av en kjernemagnetisk resonansundersøkelse (NMR) av fluidet; å bestemme en longitudinal relaksasjonstid, T1 og en tilsynelatende transversal relaksasjonstid, T2app, for fluidet; å danne et forhold R av T1/T2app for fluidet; og å bestemme viskositeten, ?, i henhold til forholdet, R. Et datamaskinprogramprodukt for implementering av fremgangsmåten er også tilveiebrakt.
