The studied oilfield is located in Algeria. The reservoir succession is subdivided in four lithological parts. Two main parts form the special focus of this study: part 1 and part 2. Results, based on permeability and porosity, show very low values, close to the standard cut off. The presence of fractures with a high frequency may have an important impact on production. These fractures have been identified by the use of the borehole image tools. These fractures are of different types: opened fractures and half opened and sealed. In their pattern, these fractures are longitudinal and transversal. Contribution of fractures towards the change in permeability and porosity shows a variable fluctuation, despite their considerable frequency. Thus and owing to the reservoir characteristics and their evolution, gathered to the fracture aspect presence and, for better efficiency, requirement for an application of advanced drilling technology is ideal. Therefore, the horizontal drilling type may remain an ultimate option. Since the target is to intersect a high number of fractures. The length of the horizontal section might not be long, and therefore high DLS might be tolerated. Productivity from horizontal wellbore can be as much as 20 times greater than from a comparable vertical well. The major reason for such improvement is that a horizontal wellbore affords much greater exposure to the producing zone. However, the drilling cost of a horizontal well will not exceed 2 to 2-1/2 times that of a vertical well. The advantage of horizontal drilling in such area will be also debated.
