In this study, having the data drawn from petrophysical diagrams of well #2 of Sardar-e-Jangal field located in south Caspian, the reservoir features including effective prosity, volume shal, and electrofacies in Abshoron formation were considered. Through SOM method and petrophysical diagrams data, Apshoron formation electrofacieses located in Sardar-e-Jangal field were determined. Based upon SOM method which is carried out with the direct intervention of supervior, the efficient dimensions of clusters are selected through merging petrophysical data and there were determined five electrofacieses. Electrofacies #1 and #5 demonstrate the bestand worst quality, respectively. Well logging data analysis indicates that in this reservoir the effective prosity is negatively related to volume shal, in the sense that with the increase of volume shal, a consequent decrease in thedegree of effective prosity will be spotted.
