The "BDS" oil field volumetrically has Original Oil in Place (OOIP) of 56.84 MMSTB. This field has produced 20.45 MMSTB with a current recovery factor (RF) value of 35.89%. Because the remaining reserves are still large, this field is still suitable for development. The type of driving force is a water drive with very high water production, where the water cut is more than 95% so that it has the potential to carry out secondary recovery projects using the waterflooding method using reservoir simulation. Optimization is carried out by changing the reactivated suspended well into a production well and changing it into an injection well. This effort is intended to obtain an optimum scenario for the water injection project. Specifically, the aim of this research is to utilize suspended wells to become production wells and injection wells as well as to overcome the problem of surface formation water waste with limited water treatment facilities.
