Prediction of permeability in un-cored intervals/wells is necessary to developing an effective reservoir characterization program and providing information on various depositional and diagenetic controls on pore geometry. Permeability can be obtained from well tests, core analysis and well-logs. Usually using well-log data to derive estimates of permeability is the cheapest source. In this paper, routine core analysis and well-log data of an actually existed sandstone reservoir in Gulf of Suez (Egypt) were used to develop permeability correlations using Hydraulic Flow Units Approach (HFU's). The core data were statistically treated for identification of Hydraulic Flow Units. This involves the calculations of Reservoir Quality Index (RQI), Flow Zone Indicator (FZI), and Pore Level Heterogeneity Index(PLHI).Results showed that, Six HFU's were identified from core data and each unit has its own FZI. A correlation between FZI calculated from core data and that obtained from well-log data was developed for estimating permeability in un-cored intervals/wells. Application of the Pore Level Heterogeneity Index concept to the data ensured the existence of six rock types in the studied reservoir.
