Fractured Reservoirs provide over 20% of the world reserves and production. However, few of these reservoirs are optimally developed. It is undeniable that the reservoir characterization modeling and simulation of naturally fractured reservoirs present unique challenges that differentiate them from conventional reservoirs which also mean that they require unique solutions and strategies for optimum production.

Zeit Bay field is considered as the first field in the Egyptian Petroleum Sector that explored and produced oil from the Fractured Basement. This field is located in the southwestern offshore part of the Gulf of Suez. The field was discovered in June 1981 and started to produce commercially since December 1983. Hydrocarbons are produced from all the porous and permeable intervals from Hammam Faraun of Belayim Formation down to Pre-Cambrian basement. These units are in complete hydraulic communication, making it one of the unique reservoirs.

In this study, the authors use all available data and various methods and techniques in this study to construct a Reservoir Model for Basement Reservoir of Zeit Bay field aiming to:

1) Identify and model Basement Reservoir that predicts content and behavior of wells.

2) Explain the past Basement reservoir performance and predict its future performance.

3) Formulate a reservoir management policy and development plane of the field throughout its life with minimum expenditures
