The accurate determination of saturation-height relationships, based on individual facies, is an important prerequisite for the delineation of hydrocarbons within a reservoir. Various methods for modeling saturation-height relationships are compared, including advantages and disadvantages. For the cases considered, it is shown that a modified hydraulic Flow Zone Unit (FZU approach offers greater flexibility and accuracy than other methods, integrating core data with petrophysical log analysis results. Saturation profiles for Australian offshore fields are determined for a wide range of FZUs, where geological attributes and petrophysical characteristics can be traced back to "Global Characteristic Envelopes" (GCE. This approach of deriving saturation profiles is able to accurately predict reservoir connate fluid distributions.
