dc.description.abstractWater flooding is a process of hydrocarbon recovery where water is injected through injection wells into the reservoir to recover oil from the production well. It is usually injected in a reservoir rock that has fluid communication with the producing reservoir. Waterflooding is secondary recovery mechanism whose purpose is to maintain and support reservoir pressure thus displacing hydrocarbon towards the producing wellbore. In this study a reservoir in the Niger Delta, Reservoir OZ-70 is used for evaluation and economic analysis of the water flooding project using five spot pattern. Reservoir OZ-70 had oil at the start of the flood to be 2.38MMSTB. The reservoir was left depleted with the unrecovered oil in it. But based on the analysis carried out on secondary oil recovery by water flooding, 0.98 MMSTB was recovered from 2.38 MMSTB about 41.1% at a breakthrough period of 428 days. When water viscosity was increased from 0.60 to 0.65, 0.99MMSTB about 41.7% was recovered. Economic evaluation of the reservoir oz-70 water flooding project was also performed. Net present value (NPV) was calculated to be $8.74million while internal rate of return (IRR) at a discount rate of 10% was 126.3%. Therefore, since the NPV is greater than zero and IRR greater than hurdle rate (10%) the project is economically viable.
