These cross plots are similar in format to standard industry charts, which provide a further tool for improved petrophysical characterization using rapid, non-destructive magnetic susceptibility measurements.Evaluating and identifying faults and fluid contact in hydrocarbon bearing reservoir rocks are challenging tasks. The work presented in this thesis has shown for the first time that raw magnetic susceptibility measurements performed on drill cuttings can be used to detect faults and fluid contacts in sedimentary sequences. Such measurements can be performed at well site, thereby enabling companies to make important field developments decisions quickly.HYDROCARBON RESERVOIR
