Abstract

Electrofacies study is one of the useful methods in the petrophysical analysis of wells without real geological data that can be used in the study of reservoir properties. In this research, on the basis of thin section studies from the Bangestan reservoir in one of the wells within the Mansouri oil field, four sedimentary facies were identified. Based on electrical logs analysis and using clustering method of MRGC, electrical models with 14 electrofacies were identified. The combination of electrofacies, based on average values of their CGR, led to an optimized model which was composed of three facies. Because of a good correlation between the optimized model and real geological data in one of the studied wells, this model can be used for the evaluation of other wells in this field. We hope this model can be used in the future studies of this field in the evaluation of reservoir properties and modeling
