Abstract Gamma oil field is considered as oil producer from Nubia sandstone Formation. It lies in the southwestern part of the Gulf of Suez. The penetrated Nubia Formation in the available wells has good reservoir characteristics. It is mainly sand and shale (kaolinite) facies . Moreover, the porosity model reflects a good porosity in the area with values ranging from 11% to 22%. Conversely, the water saturation values show that all available wells are located under the oil-water contact and are highly saturated with water. Consequently, a 3D static model was carried out to distinguish the hydrocarbon distribution, mapping, and validate any Nubian sandstone reservoir upside exploration potential in the area. Accordingly, the property models and maps results show that the upside potential blocks at the southeastern direction reflected a highly promising for hydrocarbon prospecting where the water saturation values reflect an obvious decrease and the volumetric calculation of the OOIP (original oil in place) in the upside blocks is about 19.3 MMSTB, this reflects the economic importance of hydrocarbon accumulations in the Nubia sandstone Formation in the predicted area.
