Abstract
The off-shore Nile Delta is one of the most promising areas for gas exploration and production in Egypt and the Middle East. The present study deals with evaluation of the gas-bearing sand anomalies at the off-shore Nile Delta of Egypt using the available well logging and the pressure datasets. The early to middle Pliocene sediments (Kafr El Sheikh Formation) of eleven wells scattered in the Darfeel and Port Fouad Concessions are analyzed and studied for determining the different petrophysical parameters necessary for reservoir evaluation. This study reveals the presence of three gas-bearing sand zones (anomalies-1, -2 and -3), with good hydrocarbon potential, encountered at different depth levels at the Early Pliocene sediments of Kafr El Sheikh Formation. The detailed petrophysical analysis of these zones shows that anomalies-1 and 2 attain good reservoir parameters, while anomaly-3 is not penetrated in majority of wells in the study area. However, anomaly-2 exhibits unique characteristics; in terms of the good porosity (27 to 33%), low shale volume (Vsh
