Formation Evaluation and Lithology Determination for Selected Wells at Aghar Field, Western Desert, Egypt

Abstract

The aim of the present work is the evaluation of the petrophysical parameters of The Lower Bahariya Formation using well logging data for seven wells scattered in the study. Petrophysical parameters  for Lower Bahariya Formation were calculated using a software program  in order to better development and understanding of hydrocarbon potentialities of Lower Bahariya  Formation at Aghar  Field, Western Desert , Egypt .

Also a lithology identification with cross plots (Neutron-Density), (Sonic-Density) and (Sonic-Neutron) show that the main lithology is sandstone ,limestone, dolomite and shale. It was found that, the porosity of  Bahariya Formation in AG-2x well varies from 4.8% to 32.4 % . Also, hydrocarbon Saturation in the studied area exhibit increase in middle and decreases in all direction where maximum value in AG-1X 0.75 %  at the studied area.
