Application of nanofluids flooding in the oil and gas industry is recently emerging as enhanced oil recovery methods. Nanoparticles have the ability to alter the rock formation in order to recover oil trapped in the pores of the rock to improve oil recovery. In this study, core plug samples were formulated in the laboratory to investigate the effect of nanoparticles on oil recovery. The formulated core samples were saturated in low salinity brine. However, low salinity brine was used because it has the ability to alter rock wettability. After core flooding with brine for secondary recovery process, extracted oil from Irvingia gabonensis was introduced into the formation to investigate the effect of Irvingia gabonensis on oil recovery. The result of the study showed that magnesium oxide, silicon oxide, aluminum oxide and zinc oxide had oil recovery of 38.1%, 45.6%, 47.7% and 35.1%, respectively. However, when the nanofluids with Irvingia gabonensis were injected into the formation as a displacing agent, the oil recovery greatly improved to 50.3%, 52.0%, 53.2% and 52.4% for (MgO, SiO₂, Al₂O₃ and ZnO). The result of the study showed that nanofluid flooding is a promising potential to improve oil recovery in the Niger Delta.

在尼日尔三角洲通过用Irvingia gabonensis纳米流体驱油来提高采收率

纳米流体驱油在石油和天然气工业中的应用最近作为增强的采油方法而出现。纳米颗粒具有改变岩层的能力，以回收被困在岩石孔隙中的油，从而改善油的回收率。在这项研究中，在实验室中配制了岩心塞样品，以研究纳米颗粒对石油采收率的影响。配制的岩心样品在低盐度盐水中饱和。但是，使用了低盐度盐水，因为它具有改变岩石润湿性的能力。用盐水岩心驱油进行二次采收后，将Irvingia gabonensis的提取油引入地层，以研究Irvingia gabonensis的效果。关于石油采收。研究结果表明，氧化镁，氧化硅，氧化铝和氧化锌的采油率分别为38.1％，45.6％，47.7％和35.1％。但是，当将具有Irvingia gabonensis的纳米流体作为驱替剂注入地层中时，（MgO，SiO ₂，Al ₂ O ₃和ZnO）的采油率大大提高到50.3％，52.0％，53.2％和52.4％。研究结果表明，纳米流体驱替是提高尼日尔三角洲石油采收率的有希望的潜力。
