Relationship between pore throat and permeability of porous carbonate reservoir in the Middle East

Abstract A significant behavior of carbonate reservoirs is poor correlation between porosity and permeability. With the same porosity, permeability can vary by three orders magnitude or more. An accurate estimation for reservoir has been a challenge many years. The aim this study was to establish relationships pore throat, This indicates that throat radius corresponding mercury saturation 20% (R20) best predictor carbonates with complex porous networks. Quantitative analysis made achieve different patterns 417 samples which cover all types rocks. Different radius, have identified in patterns, are utilized predict more patterns.
