| Abstract | ||
| The offshore Nile Delta is emerging as an important source of natural gas for Egypt. Port Fouad Marine field is a big gas field discovered in 1992 by the international Egyptian oil company in the eastern part of the offshore Nile Delta, it is a gas producer from Wakar reservoir. It is located between longitudes 31° 84’, 32° 44’E and latitudes 31° 52’, 31° 30’N.The aim of this study is to determine the petrophysical parameters of wakar reservoir that are estimated from the analysis of the available log data such as (GR, neutron,density and Resistivity logs) of four wells (PFM-1, PFM-2, PFMSE-1and PFM-3 by using Schlumberger techlog, (2015.3) software. The Wakar reservoir classified into three levels of S-1, S-2 and S-3. The lithologic components of the three levels are mainly shale and some `sandstone that determined using neutron & density cross plot. The resultant petrophysical parameters values revealed that Wakar level S-1 is gas bearing zone except PFM-2 well and Wakar level S-2 is gas productive zone in PFM-3 only. But Wakar level S-3 is mainly water bearing in all wells. Wakar level S-1 show the most advanced petrophysical characterization as a desired reservoir with shale volume ranges from 5.6% to 17.2%, good effective porosity ranges from 14.7% to 24.9% and high values of hydrocarbon saturation ranges from 46.4% to 72.1%. wakar level S-2 in PFM-3 with shale volume 0.7%, effective porosity 21.8%, water saturation 63.8%n and hydrocarbon saturation 36%. Finally drawing Iso-parametric maps of petrophysical parameters to reflect the variation of reservoir properties in the area of study. | ||
