英文摘要	Hydraulic flow units and rock types in the Middle and Lower Bahariya Formation encountered in different drilled wells in NEAG-1 field were investigated. These are governed by lithologic variations and flaser laminations characterizing the Bahariya deposits, while they have a direct impact on sedimentation and digenetic process. The measured pore throat radius (r35) using mercury injection capillary pressure (MICP) technique were used to develop self-reliant trend lines with reliable formula derived from laboratory petrophysical measurements. Petrographic investigations were used for outlining mineralogy, porosity types and mode of occurrence of formation fines. X-ray diffraction technique (XRD) of bulk samples was used for detecting rock forming minerals, mineralogy of cementing materials and their quantitative dominance in the pore spaces of the studied Bahariya sandstone samples. The Primary and secondary porosity either interparticle or intraparticle are controlling by pore space architecture while, four reservoir rock types (T-1, T-2, T-3 and T-4) are detected. Each rock type reflects different sedimentary environmental agent, degree of digenesis and variation in mineralogy. The calculated equations predict that up to 85 % of measured permeability data demonstrate 10 hydraulic flow units which reveal the value of r35 standing between 0.2 mu m and 3. 11 mu m. The relationship between helium porosity and nitrogen permeability for the studied samples are supported by high coefficients of correlation (R2 = range 0.75 to 0.85) allowing reservoir characterization and permeability prediction from measured average porosity of each reservoir rock type. Different empirical relationships were constructed in order to facilitate hydrocarbon exploration and development in the Neag-1 oil field in the Egyptian Western Desert.
