“…The nanofluid density is higher than that of the water or the base fluid, and its value increases as the nanoparticle concentration increases in the base fluid (Devendiran and Amirtham 2016). Also, there is a linear correlation between the nanofluid density and the concentration of nanoparticles, mainly at ambient temperature (Sommers and Yerkes 2010), although the potential of nanoparticles to control fines migration in the sand sample (Al 2 O 3 , SiO 2 , and MgO) increases with nanofluid concentration (Mansouri et al 2019).…”

“…Nanofluids have an inverse relationship with salinity, where the nanofluids become less stable when salinity increases accordingly, which in turn is an indicator of the occurrence of the agglomeration of particles in the fluid. Mansouri et al (2019) reported the effect of nanofluid on fines migration in low-salinity water. The results showed that the SiO 2 nanofluid could reduce the production of fines when mixed with low-salinity water.…”

A novel concept of treating oil reservoirs by nanofluids is being developed to improve oil recovery and reduce the trapped oil in hydrocarbon reservoirs. Nanoparticles show great potential in enhancing oil recovery under ambient conditions. In this paper, the approaches of wettability alteration by using nanofluid, stability of nanofluids, and the most reliable wettability alteration mechanisms associated with variant types of nanoparticles have been reviewed. Moreover, the parameters that have a significant influence on nanofluid flooding have been discussed. Finally, the recent studies of the effect of nanoparticles on wettability alteration have been summarised and analysed. Furthermore, this paper presents possible opportunities and challenges regarding wettability alteration using nanofluids.

“…Later, Khilar and Fogler found that when injected fluid salinity falls below a critical salt concentration (CSC), fines are released and migration starts within porous media. Fine migration and subsequent permeability reduction were also confirmed by experimental research. ,,,,,− Kumar et al and Mansouri et al used scanning electron microscopy (SEM), the field emission SEM, and atomic force microscopy to visually show the mobilization of mixed-wet kaolinite particles with high-resolution images.…”

Formation damage caused by fine migration and straining is a well-documented phenomenon in sandstone reservoirs. Fine migration and the associated permeability decline have been observed in various experimental studies, and this phenomenon has been broadly explained by the analysis of surface forces between fines and sand grains. The Derjaguin−Landau−Verwey−Overbeek (DLVO) theory is a useful tool to help understand and model the fine release, migration, and control phenomena within porous media by quantifying the total interaction energy of the fine−brine−rock (FBR) system. Fine migration is mainly caused by changes in the attractive and repulsive surface forces, which are triggered by mud invasion during drilling activity, the utilization of completion fluid, acidizing treatment, and water injection into the reservoir during secondary and tertiary recovery operations. Increasing pH and decreasing water salinity collectively affect the attractive and repulsive forces and, at a specific value of pH, and critical salt concentration (CSC), the total interaction energy of the FBR system (V T ) shifts from negative to positive, indicating the initiation of fine release. Maintaining the system pH, setting the salinity above the CSC, tuning the ionic composition of injected water, and using nanoparticles (NPs) are practical options to control fine migration. DLVO modeling elucidates the total interaction energy between fines and sand grains based on the calculation of surface forces of the system. In this context, zeta potential is an important indicator of an increase or decrease in repulsive forces. Using available data, two correlations have been developed to calculate the zeta potential for sandstone reservoirs in high-and low-salinity environments and validated with experimental values. Based on surface force analysis, the CSC is predicted by the DLVO model; it is in close agreement with the experimental value from the literature. The critical pH value is also estimated for alkaline flooding. Model results confirm that the application of NPs and the presence of divalent ions increase the attractive force and help to mitigate the fine migration problem. Hence, a new insight into the analysis of quantified surface forces is presented in current research work by the practical application of the DLVO theory to model fine migration initiation under the influence of injection water chemistry.

Effects of nanosilica on fine migration and location distribution of blockage at different pH and temperatures: Modelling and experimental studies

There are a lot of fine particles in sandstone reservoirs that are not strongly bonded to the rock's surface. These fine particles move with the fluid flow and cause formation damage and facilities' erosion. An effective method for preventing fine migration is using nanoparticles (NPs). In this study, modelling and experimental methods were utilized to investigate NPs' effect on fine migration. The Derjaguin–Landau–Verwey–Overbeek (DLVO) theory was used to model NPs' effect on the stability of fines on the rock's surface. Long sand packs were utilized to study the silicon dioxide NPs' effect on fine migration and location distribution of blockage in experiments at different pH and temperatures. Modelling results showed that the presence of NPs reduces the zeta potential of fine surfaces from −27.6 and −35.6 mV to −1.8 and −6.7 mV at pH = 8 and pH = 12, respectively. Based on the DLVO theory, it was concluded that NPs increase the particles' stability on the rock's surface. The experimental results showed that although fine migration increases with an increase in pH and temperature, the presence of SiO2 decreases it by 58% and 38% at pH = 8 and 12, respectively. The results showed that the performance of NPs reduced with an increase in pH and temperature. It was shown that the presence of NPs influences the location distribution of pressure drop and leads to permeability being more homogeneous in porous media during low salinity water injection.
