| Summary: | We performed a simple 3D compositional reservoir simulation study to examine the possibility of waterflooding the Soku E7 gas-condensate reservoir. This study shows that water injection results in higher condensate recovery than natural depletion. To achieve this recovery, the reservoir should return to natural depletion after four years of water injection, before water invades the producing wells. Factors that affect the effectiveness of water injection in this reservoir include aquifer strength, reservoir property distribution, timing of the start of injection, and intra-reservoir shale thickness and continuity. Sensitivity analyses used to quantify the effects of these factors on condensate recovery indicate the need to acquire more production, pressure and log data to reduce the present large uncertainty on aquifer strength before proceeding on waterflooding this reservoir. The study also shows that the injection scheme should be implemented as soon as possible to avoid further loss of condensate recovery. The result of this study is applicable to other gas condensate reservoirs in the Niger delta with similar depositional environments. |
