Murzuqbasin represent one of the most important basins in libya. It has many oil fields; (A) field is one of the new discoveries in NC186 concession in Murzuqbasin. The present paper deals with evaluation of petro-physical parameters of Hawaz Formation in (A) oil field, Murzuq basin through the analysis of well-log data available for two exploratory wells, distributed in (A) oil field. A comprehensive formation evaluation has been applied through numbers of cross-plots and using their output parameters as input data for interactive petro-physics software (IP) in order to evaluate the lithological constituents and fluid saturations. The litho-saturation cross-plot indicated that the Hawaz Formation consists of sandstones with few shale. These sandstones are generally fine to very fine grains but occasionally coarse to very coarse grained. Generally coursing upward sequence is indicated. The litho-saturation cross-plots also illustrated that horizon H4, H5 and H6 are the main reservoirs in Hawaz formation
