Abstract

Nanoparticles (NPs) based techniques have shown great promises in all fields of science and industry. Nanofluid-flooding, as a replacement for water-flooding, has been suggested as an applicable application for enhanced oil recovery (EOR). The subsequent presence of these NPs and its potential aggregations in the porous media; however, can dramatically intensify the complexity of subsequent CO2 storage projects in the depleted hydrocarbon reservoir. Typically, CO2 from major emitters is injected into the low-productivity oil reservoir for storage and incremental oil recovery, as the last EOR stage. In this work, An extensive serious of experiments have been conducted using a high-pressure temperature vessel to apply a wide range of CO2-pressure (0.1 to 20 MPa), temperature (23 to 70 °C), and salinity (0 to 20wt% NaCl) during CO2/water interfacial tension (IFT) measurements. Moreover, to mimic all potential scenarios several nanofluids at different and NPs load were used. IFT of CO2/nanofluid system was measured using the pendant drop method as it is convenient and flexible technique, particularly at the high-pressure and high-temperature condition. Experimentally, a nanofluid droplet is allowed to hang from one end of a dispensing needle with the presence of CO2 at the desired pressure and temperature. Regardless of the effects of CO2-pressure, temperature, and salt concentration on the IFT of the CO2/nanofluid system, NPs have shown a limited effect on IFT reduction. Remarkably, increased NPs concentration (from 0.01 to 0.05 wt%) can noticeably reduce IFT of the CO2-nanofluid system. However, no further reduction in IFT values was noticed when the NPs load was ≥ 0.05 wt%. Salinity, on the other hand, showed a dramatic impact on IFT and also on the ability of NPs to reduce IFT. Results showed that IFT increases with salinity particularly at relatively low pressures (≤ 5 MPa). Moreover, increased salinity can eliminate the effect of NPs on IFT. Interestingly, the initial NP size has no influence on the ability of NPs to reduce IFT. Consequently, the potential nanofluid-flooding processes during EOR have no negative effect on the later CO2-geosequestration projects.

压力和温度对co2 -纳米流体界面张力的影响:对提高采收率和固碳的启示
基于纳米颗粒的技术在科学和工业的各个领域都显示出巨大的前景。纳米流体驱油作为水驱的替代品,被认为是提高石油采收率(EOR)的一种适用应用。这些NPs随后的存在及其在多孔介质中的潜在聚集;然而,这可能会极大地增加枯竭油气储层后续二氧化碳储存项目的复杂性。通常情况下,主要排放者的二氧化碳被注入到低产能油藏中进行储存和增加采收率,作为最后的EOR阶段。在这项工作中,在二氧化碳/水界面张力(IFT)测量期间,使用高压温度容器进行了广泛的实验,以应用广泛的二氧化碳压力(0.1至20mpa),温度(23至70°C)和盐度(0至20wt% NaCl)。此外,为了模拟所有可能的情况,使用了几种不同负载和NPs的纳米流体。由于垂滴法是一种方便、灵活的技术,特别是在高压和高温条件下,采用垂滴法测量CO2/纳米流体体系的IFT。在实验中,允许纳米液滴在二氧化碳存在的情况下,在所需的压力和温度下悬挂在点胶针的一端。无论CO2压力、温度和盐浓度对CO2/纳米流体体系的IFT的影响如何,NPs对IFT的降低作用有限。值得注意的是,增加NPs浓度(从0.01 wt%到0.05 wt%)可以显著降低co2 -纳米流体系统的IFT。然而,当NPs负荷≥0.05 wt%时,IFT值没有进一步降低。另一方面,盐度对IFT和NPs降低IFT的能力有显著影响。结果表明,IFT随盐度的增加而增加,特别是在相对较低的压力下(≤5 MPa)。此外,增加盐度可以消除NPs对IFT的影响。有趣的是,初始NP大小对NP减少IFT的能力没有影响。因此,提高采收率过程中潜在的纳米流体驱油过程对后期的二氧化碳封存项目没有负面影响。
