Wettability Alteration by Nanofluids
Research Guide
What is Wettability Alteration by Nanofluids?
Wettability alteration by nanofluids uses nanoparticle-stabilized fluids to modify rock surface wettability from oil-wet to water-wet, enhancing oil mobilization in reservoirs.
This technique applies metal oxide nanoparticles like SiO2, ZrO2, and TiO2 dispersed in brine to alter wettability in carbonate rocks. Core-flood experiments demonstrate recovery improvements of 10-30% in oil-wet systems (Karimi et al., 2012; Hendraningrat and Torsæter, 2014). Over 20 papers since 2012 review mechanisms, stability, and EOR performance.
Why It Matters
Nanofluids enable chemical EOR in high water-cut carbonate reservoirs where traditional surfactants fail due to adsorption losses. Karimi et al. (2012) showed ZrO2 nanofluids shift contact angles from 140° to 40°, boosting recovery by 25% in core floods. Hendraningrat and Torsæter (2014) demonstrated SiO2 nanoparticles improve recovery in both water-wet and oil-wet sandstones by 15-20%. Gbadamosi et al. (2019) highlight applications in heterogeneous reservoirs, reducing residual oil saturation.
Key Research Challenges
Nanofluid Stability
Nanoparticle aggregation reduces dispersion stability under reservoir conditions. Hendraningrat and Torsæter (2014) report SiO2 nanofluids stable only up to 0.1 wt% in high-salinity brines. Sun et al. (2017) note thermal degradation limits field-scale use.
Adsorption Mechanisms
Excessive nanoparticle adsorption blocks pores without optimal wettability change. Karimi et al. (2012) observed ZrO2 adsorption alters zeta potential but requires optimization. Nazari Moghaddam et al. (2015) found varying adsorption rates across nanoparticle types in carbonates.
Core-Flood Scalability
Lab core-flood results show promise, but upscaling to reservoirs faces injectivity issues. Roustaei and Bagherzadeh (2014) achieved 15% recovery gain with SiO2, yet field trials lack data. Ali et al. (2018) stress need for heterogeneous model validation.
