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 the evaluation of the gas-bearing sand intervals at the off-shore Nile Delta of Egypt using the available geophysical logs and pressure datasets. The Middle to Late Miocene sediments (Wakar and Sidi Salim Formations) of four wells distributed in Port Fouad concession are analyzed and studied for determining the different petrophysical parameters that are necessary for reservoir evaluation. This study reveals the presence of multi gas-bearing sand zones in Wakar S1 level and Sidi Salim Formation, with good hydrocarbon potential, encountered at different depth levels. The detailed petrophysical analysis of these zones show that S1 level has good reservoir parameters and gas potentiality in all wells except in PFM S-1 well which is dry, while S2 and S3 levels are either shaled out or water bearing in the study area. However, the Wakar S1 level exhibits unique characteristics in terms of the good porosity (18 to 30%), low shale volume (Vsh<10%) and high gas potentiality (41 to 92%). The analysis of pressure data is concerned mainly with locating the different fluid contacts, determining the pressure gradients of the gas-bearing zones, and defining the different hydrocarbon densities. Pressure gradient ranges of 0.065 to 0.325 psi/ft are indicated for Wakar S1 level.
