Determining the stone species of the reservoir is a collaborative process between Geology and Petrophysics that identifies the geological facies by their dynamic behavior. This study has been done based on available information from 3 wells existed in the field and in this case the Bangestan reservoir has been divided into 6 reservoir and non-reservoir zones. Because each zone can be composed of one or more rock types with similar lithological and petrophysical characteristics that subsequently shows almost identical dynamic behavioral characteristics, therefore in this research 5 rock type from Bangestan reservoir succssetions have been determined in this field that are arranged in the presented zoning structure. To achieve the main purpose of this study, the target succssetions has been evaluated in different steps such as: identifying the facies in 2 Microscopic and macroscopic levels, studying the current texture and fabric of the facies, Understanding the environmental conditions of the area at the time of deposition, analyzing the processes after the deposition and understanding the changes caused by these effects, the thickness of each zone and understanding its changes in the ranges of field, identifying the types of the pores and understanding the effective factors in their creation, Petrophysical measurements based on core data and well loge graphs and Finally creating are as on able relationship between the fabric of rock types and petrophysical features related to them. Based on these presented research process, Ilam formation has been divided into (A and B) reservoir zones ,Sorgah formation has been divided into one nonreservoir zone, and Sarvak has been divided into 3 (D,E,F)reservoir zones, that A zone related to upper section of  Ilam formation and C zone -belonged to entire sequence of Sorgah formation-  are identified with Highest and lowest reservoirquality between the other zones.
