The research of the current study is primarily focused on evaluating the reservoir performance by utilizing waterflood technique, based on a case study at Lanea oil field located in Chad; various mechanisms along with approaches were used in considering the best suitable pattern for waterflooding. All the simulation work was compared against a base case, where there was no involvement of water injection. Moreover, for the base case, a significant amount of oil left behind and cannot be swept, because of lower reservoir pressure at the downhill. The recovery factor obtained was in the range of 14.5–15% since 2010, and in order to enhance the oil production, an injection well was applied to boost the reservoir pressure; oil recovery is improved. In addition, sensitivity analysis study was performed to reach the optimum production behavior achieved by possible EOR method. Parameters, such as grid test, injection position, proper selection production location, permeability, and voidage substitution, were defined in the simulation study.

目前的研究主要集中在利用乍得的Lanea油田的案例研究，通过注水技术评估储层性能。在考虑最合适的注水模式时，采用了各种机制和方法。将所有模拟工作与不涉及注水的基本情况进行了比较。此外，对于基本情况，由于下坡油藏压力较低，因此会留下大量油且无法清除。自2010年以来，获得的采收率在14.5％至15％的范围内，并且为了提高石油产量，使用了注入井来提高油藏压力。石油采收率得到改善。此外，进行了敏感性分析研究，以达到通过可能的EOR方法获得的最佳生产性能。在模拟研究中定义了参数，例如网格测试，注入位置，正确选择的生产位置，渗透率和空隙率替代。
