The study of petrophysical parameters plays a major role in the evaluation of hydrocarbon reservoirs. In this study, using well data in Geolog software, the petrophysical parameters of the Arab Formation (equivalent to Surmeh) in one of the oil fields in southern Iran were studied in two ways. Based on the petrophysical evaluation and using conventional cross-plots (neutron-density) and histogram of porosity and water saturation, the lithology of the Arab Formation was determined. The lithology consists of a combination of calcite, dolomite, and anhydrite. Comparison of the results of porosity changes is more consistent with the values obtained from core analysis. According to the calculated petrophysical properties, the upper part of the Arab (Surmeh) Formation was divided into seven parts. Comparison of water saturation showed that in all zones, the range of changes is high. By comparing the zones quality, zones 5 and 6 are introduced as the best reservoir zones. [ABSTRACT FROM AUTHOR]
