Heterogeneity analysis and hydraulic flow unit (HFU) determination of the hydrocarbon reservoirs play an important role in the reservoir behavior. In the present research work hydraulic flow units of the Dalan and Kangan formations in selected two drilled wells (Well# B and Well# A) of one of oil fields in the Persian Gulf basin were determined. Heterogeneity value of the Kangan-Dalan reservoir is 0.84-0.86 in wells under study based on Lorenz coefficient calculation which is indicated high heterogeneity. The results revealed 3 flow units using improved stratigraphic Lorenz plot, core data, well logs and related equations. The method was used to divide formation in view of flow units in the environment of Geolog software. The results revealed that HFU1 - HFU3 and HFU2 are indicating higher and lower reservoir quality, respectively. Based on petrographic analysis of 1600 thin sections of Kangan and Dalan formations twelve sedimentary lithofacies were determined. These facies were also discussed in view of reservoir quality and diagenetic processes effects. Hydraulic flow unit distributions in 5 reservoir zones were exhibited that zone -4 is in the best quality state due to predominance of HFU1. Therefore, according to the present results the reservoir behavior is too much difficult to predict in other locations.
