The representative PVT was validated most properly using the Al-Shammasi correlation to describe oil formation volume factor, Casey-Cronquist correlation for gas solubility. Therefore, nine core samples from the reservoir were evaluatedAccurate reservoir characterization is a key step in developing, monitoring, and managing a reservoir and optimizing production. To achieve accuracy and to ensure that all the information available and have good accuracy. In this research study the fluid and rock properties for Belhedan Oil field that produced from a complex faulted sandstone reservoir. The available PVT laboratory tests and core data were analyzed to select the representative PVT sample and core sample that can be used with high certainty for reservoir and production engineering application required to develop and produce the field reserve, with high efficiency that leads to maximize the oil recovery.Integrated of the Relative Permeability, Capillary Pressure and Fractional Flow Curve to Present Fluid Distribution in Gargaf Formation, Belhedan Oil Field, Sirte Basin
