“…The increase of SNP concentrations has led the accumulation of particles at the interface, resulting in particles aggregation. The formation of foam will be prohibited as the particles aggregation at foam film surface inducing the film to rupture [40,41]. Possible mechanism of liquid file stabilization by surfactant and nanoparticle is illustrated in Figure 4 as proposed by Xue et al [25].…”

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.

“…Nanoparticles are solids and the foams they stabilize are expected to be highly resistant to unfavourable reservoir conditions of high salinity and temperatures [130]. The stability of nanoparticlestabilized foam does not depend on the modification of the polymer chain or surfactant chemical structure like conventional chemical-stabilized foams [131].…”

Despite the progress made on renewable energy, oil and gas remains the world's primary energy source. Meanwhile, large amounts of oil deposits remain unrecovered after application of traditional oil recovery methods. Chemical enhanced oil recovery (EOR) has been adjudged as an efficient oil recovery technique to recover bypassed oil and residual oil trapped in the reservoir. This EOR method relies on the injection of chemicals to boost oil recovery. In this overview, an up-to-date synopsis of chemical EOR with detailed explanation of the chemicals used, and the mechanism governing their oil recovery application have been discussed. Challenges encountered in the application of the various conventional chemical EOR methods were highlighted, and solutions to overcome the challenges were proffered. Besides, the recent trend of incorporating nanotechnology and their synergistic effects on conventional chemicals stability and efficiency for EOR were also explored and analysed. Finally, laboratory results and field projects were outlined. The review of experimental studies shows that porescale mechanisms of conventional chemical EOR is enhanced by incorporating nanotechnology, hence, resulted in higher efficiency. Moreover, the use of ionic liquid chemicals and novel alkaline-cosolvent-polymer technology shows good potentials. This overview presents an extensive information about chemical EOR applications for sustainable energy production.

Enhanced oil recovery in fractured reservoirs is challenging because injected fluids flow mainly through the fractures without displacing oil from the matrix. Foam can enable injection into the matrix by creating a high pressure in the fractures. However, the foam has to be strong and stable in the presence of oil recovered from the matrix. This study focuses on developing a strong foam using nanoparticles and surfactants. Ethyl cellulose nanoparticles (ECNP) with a relatively narrow size distribution were prepared and dispersed in brine along with a nonionic surfactant (SF). The SF performed as both a nanoparticle dispersion agent and a foaming agent. The foam by ECNP/SF had better foamability and stability than the SF foam in the presence of oil. The mobility reduction factor of the ECNP/SF foam was 100 times larger than that of the SF foam and 3 times larger than an alpha olefin sulfonate (AOS) foam in a sand pack. Foam was injected into a fractured oil-wet Texas Cream limestone core saturated with oil. The oil recovery due to the ECNP/SF foam was significantly higher than those with only gas injection and conventional AOS foam injection. The novelty in this work lies in combining nanoparticles with surfactants to generate a strong foam which can be used to improve oil recovery from fractured, oil-wet reservoirs.
