.... It is in many cases difficult to understand the exact behavior of log responses especially in complex lithologies. A new cross plot approach is used in this paper to take into account all the lithological possibilities. The cross plots are normally used in well log analysis for interpreting both for lithology...

... carbonate facies model, several methods are introduced to classify carbonate facies using well log data. These methods can be generalized in two major directions: using empirical equation such as Archie equation or rock fabric equation to classify facies (Asquith, 1985; Holtz and major 2004; Lucia, 2005...
