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.

“…Nanotechnology can be applied for EOR in three major approaches: nanoemulsions, nanocatalysts, and nanofluids [3]. A nanofluid is a fluid in which nanoparticles are suspended in a base fluid such as brine or deionized water [4]. The injected nanoparticles into the reservoirs can improve oil recovery by wettability alteration, interfacial tension reduction, and disjoining pressure [5].…”

Jang et al [4] used GPTMS, (3-Glycidoxypropyl) trimethoxysilane to modify the stability of silica nanoparticles in high-salinity and high-temperature conditions. They used these nanofluids to alter the wettability of carbonate rocks from oil-wet to water-wet and neutral-wet conditions.…”

The main challenge of the application of nanofluids for enhanced oil recovery (EOR) in oil-wet carbonate reservoirs is maintaining their stability under high-temperature and high-salinity which is normally seen in reservoir conditions. In this work, surface-modified TiO2 nanoparticles were synthesized by N-(2-Aminoethyl)-3-Aminopropyltrimethoxysilane (AEAPTMS) as a coupling agent for surface modification of nanoparticles. Zeta potential and dynamic light scattering analyses were used to evaluate the stability of the prepared nanofluids. Results indicated that nanofluids had high stability in 90 °C and 20 wt.% salinity. The influence of nanofluids on wettability alteration of carbonate rocks was studied by measuring the contact angle value. Untreated rock samples were strongly oil-wet, with water advancing and receding contact angles of 165.1° and 166.2°, respectively. After treatment with 3wt.% concentration of surface-modified TiO2 nanoparticles, the rock plate wettability changed to a water-wet state, with water advancing and receding contact angles of 37.6° and 48.2°, respectively. Suggested surface-modified TiO2 nanoparticles were more effective in wettability alteration of the rock surfaces compared to the un-modified TiO2 nanoparticles. Furthermore, higher concentration of nanoparticles, higher the ability of the nanoparticles on changing the rock wettability.

“…The stability of nanodispersions can be improved by electrostatic or steric stabilization mechanisms [ 23 ] to make them suitable for EOR applications. Recently, (3-glycidyloxypropyl) trimethoxysilane (GLYMO), a hydrophilic silane, has been proposed by many researchers to stabilize nanodispersions in hostile environments [ 24 , 25 , 26 , 27 ]. Worthen et al [ 24 ] compared silica nanoparticles of 7–20 nm size stabilized by three types of nonionic ligands namely, GLYMO, polyethylene glycol (PEG), and zwitterionic sulfobetaine (SB) in seawater and American Petroleum Institute (API) brine.…”

“…The stability at pH > 3.5 is not reported. GLYMO also provided colloidal stability for 3 days even at 120 • C. Jang et al [25] achieved colloidal stability of silica nanofluid up to salinity of 20% at 90 • C by modifying silica nanoparticles with GLYMO. Their wettability tests on oil-wet carbonate rocks showed effective wettability alteration to neutral-and water-wet by modified silica nanofluids.…”

The stability of nanoparticles at reservoir conditions is a key for a successful application of nanofluids for any oilfield operations, e.g., enhanced oil recovery (EOR). It has, however, remained a challenge to stabilize nanoparticles under high salinity and high temperature conditions for longer duration (at least months). In this work, we report surface modification of commercial silica nanoparticles by combination of zwitterionic and hydrophilic silanes to improve its stability under high salinity and high temperature conditions. To evaluate thermal stability, static and accelerated stability analyses methods were employed to predict the long-term thermal stability of the nanoparticles in pH range of 4–7. The contact angle measurements were performed on aged sandstone and carbonate rock surfaces to evaluate the ability of the nanoparticles to alter the wettability of the rock surfaces. The results of static stability analysis showed excellent thermal stability in 3.5% NaCl brine and synthetic seawater (SSW) at 60 °C for 1 month. The accelerated stability analysis predicted that the modified nanoparticles could remain stable for at least 6 months. The results of contact angle measurements on neutral-wet Berea, Bentheimer, and Austin Chalk showed that the modified nanoparticles were able to adsorb on these rock surfaces and altered wettability to water-wet. A larger change in contact angle for carbonate surface than in sandstone surface showed that these particles could be more effective in carbonate reservoirs or reservoirs with high carbonate content and help improve oil recovery.
