This requires a thorough understanding to the developed groundwater systems, particularly the shallow aquifers. In this study, well log data was integrated to a Vertical Electric Sounding (VES) survey acquired using Schlumberger configuration at the Khatatba area to characterize the aquifer systems. The results were interpreted using the published stratigraphic data of the study area, and consequently the extension of the identified aquifers can be laterally correlated. Two aquifer systems separated by an aquitard or basaltic layer were mapped and characterized in details. The upper aquifer corresponds to El Khashab formation that produces fresh to brackish water and generally shows unconfined condition that could locally change to partially semi confined. The second aquifer is commonly confined
