Alternative Water Source Case History

The oil field under investigation is characterized by two main geological formations, the upper one which is a carbonate and the lower one that is sandstone. In this field the injection is required to support the reservoir pressure, which is decreasing due to oil production as the development plans are implemented. While the current water supplies from the nearby river will not totally be able to supply the immediate injection needs, the field will be short of injection water required until the main water project becomes available. In order to cope with this shortage, alternative water sources were investigated and among them it was identified the regional saline aquifer as the most promising, this aquifer is located between the two main geological formations.
