The Zeit sand reservoir is one of the most prolific formations at Northwestern side of the Gulf of Suez. In this research we will try to coordinate between electrical， petrophysical properties， depositional environment and facies discrimination in order to evaluate the hydrocarbon potentiality of studied Zeit formation. The statistical parameters for potassium (K)， thorium (Th) and Th/U ratio contents have a general increase towards northwestern parts， whereas uranium (U) content has a general increase towards southeastern parts. The sandstone facies is distinguished from the other facies by its thorium content >4 ppm. U has high carbonate content (U ≥1 ppm). Rocks’ electrical properties vary greatly depending on a number of factors. Electrical measurements were taken at frequencies range of (5×10-4Hz–100 kHz) for fully saturated samples (clayey sandstone) with NaCl (20 gm/Littre). As salinity， clay content， and frequency increase， consequently does the electrical properties. The continental condition are present in northwestern part (back-sea) which is distinguished by high K percent， high Th， high Th/U ratio， and low U contents. Low K， Th， and Th/U ratio contents， with high U contents， characterize the marine depositional environment that existed around the east and southeastern parts (fore-sea coincide with the dipping of strata). Furthermore， the studied Zeit Formation has good petrophysical properties that coincide with marine conditions. The middle and eastern parts (around ISS-94 and CSS-288) is a good reservoir (porosity 36%–39%， shale content ydrocarbon saturation 71%–92%， and net pay thickness 17–63 feet).
