Abstract

Petrophysical characteristics of the Hawaz Formation in H oil field, Concession NC186 of Murzuq basin have been evaluated through the analysis of well-logging data recorded for ten exploratory and development wells. These records have been analyzed through utilizing some cross-plots and use their outputs for controlling the interactive petrophysics software in order to identify the lithological constituents and fluid saturation parameters. The litho-saturation results indicated that Hawaz Formation is mainly oil-bearing Horizons H4 and H5 are the main productive zones. The evaluation reveals also that the lithological facies consists mainly of sandstone. This facies is characterized by coarsing upward.
