Abstract
Petrophysics is the study of rock properties and their interactions with all the fluids in the reservoirs. Since oil field industry is interested on porous and permeable rocks. This study is concerning to the study of the relations that connecting rock and fluids in certain Egyptian oil field which is Marine Belayim field in the Gulf of Suez. This study can be divided into two parts: First: a detailed study of sedimentological and petrographical analyses especially study of clay mineral and clay distribution and the impact of it on porosity, and then study the impact of them on water flooding projects by using Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) and Thin Section (TS) plates for the available core samples which obtained from Kareem and Belayim formations, Middle Miocene age in the Gulf of Suez to interpret the obtained information with regard to reservoir quality. Second: the object of this part is to provide a special core analysis (SCAL Data) for description and analysis of reservoir rock properties such as oil-water relative permeability, capillary pressure and wettability for the above mentioned formations and determine their influence on Improved Oil Recovery (IOR) especially water flooding projects. This study showed that the clay mineral (Smectite, Illite, Kaolinite and Chlorite), wettability, capillary pressure and relative permeability have major impact on the water flood sweep efficiency and hence on the distribution of remaining oil saturation. An incorrect understanding of the distribution of clay minerals and remaining oil saturation may lead to ineffective reservoir management and IOR/EOR decisions.
