Abstract: Fuzzy system consisting of fuzzy rules, defuzzying and self-learning process is applied in reservoir modeling. A new reservoir modeling method by interpolation and stochastic simulation is proposed. Correlation analysis is made using measured data from famous GSLIB software. Study shows that using the fuzzy system can make a modeling of geologic parameters, effectively. Such a method is better than the traditional geostatistics methods (Kriging and sequential gaussian simulation) in modeling precision, histogram and characteristic parameter recovery.
