Abstract

The Abu Gharadig Basin is located in the northern part of the Western Desert of Egypt. It has a great importance as it is considered the most petroliferous basin in the Western Desert as far as hydrocarbon production and potential.The BED-15 field forms part of Badr El Din concession in the Western Desert some 300 km west of Cairo and some 100 km west of the BED-1 producing field. It lies within the Abu Gharadig basin.
Abu Roash Formation is one of the most producing zones in the western Desert; It is characterized by a cyclic alternation of deltaic flood-plain sandstones, coastal sandstones and shales, and shallow marine shales and limestones. It attain about 700 m in thickness and is divided into seven members (from A to G).Using well log analysis 4 reservoir units are identified within Abu Roash “C”: Unit-2, Unit-2A and Unit-3,4. Units 1 and 4 donot contain sands.
From the petrophysical analysis, it was found that, the average porosity is 18% and its value ranges between 13% to 23%, such pores are filled with more than 85% of hydrocarbons. While Core measured permeability confirmed a
homogenous distribution through the main reservoir unit in the range of 300 – 500 md.
