%X The application of new mathematics using fuzzy logic has been successful in several areas of petroleum engineering. This paper reviews the state-of-the-art of fuzzy logic applied to reservoir evaluation, especially in the area of petrophysical properties prediction and lithofacies prediction from well logs. In this paper, we will also review some fuzzy methods that have been successfully applied to case studies. Besides using fuzzy logic in establishing the model itself, fuzzy logic is also used in some cases as pre-processing or post-processing tools. This paper will act as a guide for petroleum engineers to take advantage of these advanced technologies as well as those undertaking research in this field.
