Reservoir Characterization plays an important role in Reservoir Management. Good understanding of how, why and where the reservoir produces, optimizing production can be determined. Understanding the reservoir means dissecting the data and studying the relation between all its components. Hence, the production prolife and ultimate recovery of individual wells and accumulation are heavily influenced by the environment of deposition. Accordingly, constructing a Reservoir Model will be vital for the correct setting of the optimum number of appraisal and development wells, the sizing of facilities and the definition of a reservoir management policy. Existing test and production data are also used to develop a better understanding of reservoir static and dynamic models to improve the hydrocarbon productivity.

This study describes the Reservoir Characterization Model of Zeit Bay field, Gulf of Suez, Egypt. The field represents one of the complicated oil fields as it comprises several reservoirs in complete hydraulic communication, making it one of the unique reservoirs. Hydrocarbons are produced from all the porous and permeable intervals from Hammam Faraun member of Belayim Formation down to Pre-Cambrian Fracture Basement.

The authors use all available data and various methods and techniques to construct a Reservoir Model for Zeit bay Reservoir units aiming to determine:

1. Facies distribution and reservoir quality.

2. Structural trends and trapping mechanism.

3. Fluid properties and distribution.

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