“…However, the addition of 0.5 wt% SNP at 0.5 wt% AOS, decreased the stability of the foam. Mohd et al [18] have found the most stable foam achieved at 0.4 wt% nanoparticle, slightly higher than this finding possibly due to combination effect with surfactant as foaming agent during the investigation. While [22] claimed that stable CO2 foam could only be generated at SNP concentrations ranging from 0.3 wt% to 0.5 wt% at 1000ppm AOS concentration for 15nm SNP.…”

“…Higher SNP concentrations lead to more stable foam due to attachment of more particles spreading along the foam film interface [38]. However, the foam generated was unstable when excessive SNP concentration exceeded its optimum concentration used at 0.5 wt% based on the experimental condition [18,39]. The increase of SNP concentrations has led the accumulation of particles at the interface, resulting in particles aggregation.…”

“…Foams stabilized by nanoparticle have become interest among researchers these past few years [14]. Many research efforts have been given related to nanoparticle-stabilized air in water foams [17,18,19]. Small particles can stabilize foams in the absence of any other surface-active agent [1].…”

Carbon dioxide (CO2) foams have been introduced to improve mobility of CO2 in CO2 flooding. However, using surfactant alone to stabilize CO2 foam has potential weaknesses such as high surfactant retention in porous media and the foam is thermodynamically unstable for a long-term. Nanoparticle has been an alternative in stabilizing CO2 foam longer. This study aims to analyze CO2 foam stability at varying concentrations of surfactant, silica nanoparticle (SNP) and brine. The additions of SNP in anionic surfactant of alpha olefin sulfonates (AOS)-water and in AOS-brine towards foam stability were demonstrated in this study. CO2 foam stability was measured through the foam height observation and bubble size analysis. The performance of SNP and AOS suspensions in stabilizing foam were observed at different concentrations of AOS (0.1, 0.3 and 0.5 wt%), SNP (0.1, 0.3 and 0.5 wt%) and brine (0.1, 1 and 5 wt%). The results revealed that the CO2 foams were most stable at 0.3 wt% SNP suspension in 0.5 wt% AOS-water. It was found that the most stable foams formed at concentration of 1 wt% of brine. Smaller and uniform bubble size has been produced at 0.3 wt% SNP in 0.5 wt% AOS solution. Thus, concentrations of surfactant, SNP and brine have significant effects on CO2 foam stability.

“…In recent years considerable research efforts have also been devoted to develop CO 2 foams for EOR and hydraulic fracturing applications [14][15][16][17][18]. CO 2 foam flooding has all the advantages of CO 2 flooding and in addition the low viscosity problem is mostly solved as the stable CO 2 foams have few orders of magnitude higher viscosities.…”

Abstract. Application of Enhanced Oil Recovery (EOR) in oil and gas industry is very important to increase oil recovery and prolong the lifetime of a reservoir but it has been very costly and losing properties of EOR agent due to harsh condition. Nanoparticles have been used in EOR application since they are not degradable in reservoir condition and used in smaller amount compared to polymer usage. Commonly, EOR techniques are focusing on increasing the sweep efficiency by controlling the mobility ratio between reservoir fluid and injected fluid. Thus, this research aimed to analyze the nanofluid viscosity at different particle size and shape, volumetric concentration and types of dispersing fluid, as well as to determine the oil recovery performance at different nanofluid concentration. The nanofluid viscosity was investigated at nanoparticle sizes of 15nm and 60nm and shapes of 15nm spherical-solid and porous. Five nanofluid samples with concentration ranging from 0.1wt.% to 7wt.% were used to investigate the effect of volumetric concentration. Distilled water, ethanol, ethylene glycol (EG) and brine were used for the effect of dispersing fluids. Oil recovery was investigated at five different concentrations of nanofluid samples through flooding test. It was found that viscosity of nanofluid increased with decreasing particle size and increasing volumetric concentration. Solid shape particle and increasing dispersing fluid viscosity resulted in higher nanofluid viscosity. The higher the nanofluid concentration, the higher the oil recovery obtained. It can be concluded that nanofluid properties have been significantly affected by the environment and the particle used for potential EOR application.
