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 potassi.m (K)， thori.m (Th) and Th/U ratio contents have a general increase towards northwestern parts， whereas urani.m (U) content has a general increase towards southeastern parts. The sandstone facies is distinguished from the other facies by its thori.m 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 ion 71%–92%， and net pay thickness 17–63 feet).

Water stress is a critical environmental adversity that significantly impacts the growth, development, and yield of flax plants. in this study, flax seeds were cultivated under different water irrigation requirements (WiR) (100%, 75%, and 50%) to investigate the effects of exogenously supplied nitric oxide (NO) donor sodi.m nitroprusside (SNP) as foliar treatments at concentrations of 0.0 mmol/L, 0.5 mmol/L, 1.0 mmol/L, and 2.0 mmol/L. Drought stress led to a significant decrease in plant growth, photosynthetic pi.ments, yield components such as oil and total carbohydrate percentage. it also resulted in an increase in leaf H2O2 production, lipid peroxidation levels and activities of enzymatic antioxidants including polyphenol oxidase, superoxide di.mutase, and nitrate reductase enzymes. However, foliar application of SNP improved photosynthetic pi.ments and antioxidant defense system which mitigated the negative impact of water stress on growth and yield productivity by reducing oxidative damage caused by reactive oxygen species accumulation. The use of SNP also decreased H2O2 accumulation levels, lipid peroxidation levels, and improved membrane stability. SNP treatment at concentration of 2 mmol/L showed superior results compared to other concentrations with extremely significant increases observed in yield characteristics such as oil content, total carbohydrate percentages, and unsaturated fatty acids to saturated fatty acids ratio. © 2024 the Oil Crop Research institute, Chinese Academy of Agriculture Sciences
