Title: Petrophysical Studies on Samples from Eocene Exposures West Cairo-Egypt
Author: Hassan, N. M. [ناصر محمد حسن]
Abstract: The present work deals with petrophysical and petrochemical studies on 58 limestone samples of Eocene age in two localities west of Cairo (Sakkara and Giza Pyramids Plateau). The determined petrophysical properties are: effective and total porosity, grain and bulk density, gas permeability and electrical resistivity. The petrochemical properties are weight percentages of CaC03, MgCOs, shale and sand. The computational methods used for processing the obtained data include regression analyses (least square method), correlation analysis, cluster and linkage analyses. They are used to classify and correlate rock samples using their petrochemical and petrophysical parameters. All Eocene rocks of the Giza Pyramids Plateau area were found to be more dense and less porous than those of the Sakkara area and hence the electric resistivities of rocks in the former area are higher than those of rocks in the latter area. The stratigraphic subdivisions made by conventional geologic methods for Eocene rocks are very well represented by noticeable variations in the different studied petrochemical and petrophysical properties.
