The accuracy of petrophysical models of permeability from conventional methods is relatively low. In this paper, the concept of flow units is used to evaluate formation permeability for a carbonate reservoir located in Iraq. Based on comprehensive analysis of core and well log data, flow units are established and subsequently are used to model permeability among several flow units. Correlation between porosity and permeability in each flow unit improves significantly, resulting in the establishment of a permeability model for each unit. Comparison of calculated permeability and core results indicates a highly accurate permeability model. Mercury injection data including Pc10, Rc50 and pore throat size, integrated with thin section observations, are also used to evaluate the physical properties of three distinct flow units. Permeability profiles are generated for each flow unit using well log data agree with core data. This agreement illustrates the potential and applicability of the flow unit method in complicated carbonate reservoirs.
