The entropy is the special index in the theory of the information and is employed as a criteria for the identification of the system.GIS gives us clear view about the how the different parameter of a reservoir changing with respect to entropy and anisotropy. The concept of the entropy is borrowed from the thermodynamics and statistical physics and it is a basic concept in the characterization of the lithological characteristics of a particular formation .Magnitude of the entropy, which express the degree of the heterogeneity or identification, may be used in geological studies and graphic representation of the heterogeneity of various geologic systems can be analyze by the GIS. Anisotropy coefficient is dimensionless it is dependent upon the ratio of the permeability. So anisotropy co-efficient determine the sequence of thickness of the beds by which we analyze the rock type, matrix, stratigraphy, cyclicity and fluid migration through the rocks.
