Summary: Chemical surfactant injection is an effective method for Enhanced Oil Recovery (EOR) and the use of nanoparticles can further improve its efficiency. This study investigates the effect of nanoparticle surface hydrophobicity on surfactant efficiency. It is found that the nature of nanoparticles has a significant impact on oil-water interfacial tension and surfactant adsorption inhibition. Hydrophilic nanoparticles show better performance than hydrophobic ones. The results also demonstrate nonmonotonic trends in adsorption assessments, deviating from previous studies.

Summary: This study investigates the impact of chemical enhanced oil recovery on the oil recovery of mature oil fields, identifying ultralow interfacial tensions as crucial for increasing the capillary number and mobilizing trapped oil droplets. Among the five types of equilibrium interfacial tensions studied, it was found that formulations with the lowest type IV equilibrium interfacial tension exhibited the highest oil recovery ratio in core flood tests. This highlights the importance of identifying surfactant formulations with low or ultralow interfacial tensions, particularly of type IV or V, for effective screening and predicting oil recovery performance in core flood tests and field applications.

Summary: In recent decades, low salinity water flooding (LSWF) has gained attention for its effectiveness in oil recovery. However, there is a lack of studies in the literature on the potential of using Ionic Liquids (ILs) as candidates for chemical enhanced oil recovery (CEOR) combined with LSWF. This study evaluates the synergistic effect of ILs with varying chain lengths with low saline ion tuned seawater (ITSW) for enhanced oil recovery from carbonate reservoirs. The analysis shows that ILs demonstrate a better synergistic effect with ITSW, reducing interfacial tension, altering rock wettability, and exhibiting less adsorption density at the reservoir temperature. ILs with the longest chain length ([C12mim] [BF4]) show superior properties and significantly increase oil recovery in low saline ITSW.

Summary: The study investigated low salinity water alternating CO2 injection for enhanced oil recovery in oil-wet carbonate reservoirs, considering various interfacial mechanisms. Results showed that monovalent ions inhibit CO2 dissolution due to the salting-out effect, and more water shielding effect was observed in low salinity formation water. The study also highlighted the significant change in reservoir wettability and the effectiveness of low salinity alternating CO2 injection in overcoming late-production problems.

Summary: In this study, the extract of the Passiflora plant was used as a natural surfactant for enhanced oil recovery. The optimal critical micelle concentration (CMC) was found to be 4 wt%, which resulted in a minimum interfacial tension (IFT) of 13 mN/m and a contact angle (CA) of 55 degrees on the surface of the carbonate rock. The surfactant solution enabled an additional 7.5% original oil in place (OOIP) to be extracted from the rock plug.

Summary: The mechanism of imbibition displacement in oil-wet rocks is unclear. In this study, a mathematical model was established based on the Marangoni effect to investigate the driving force of oil displacement in oil-wet capillary tube. The results show that the breakdown of the initial capillary equilibrium state due to solute diffusion plays a key role in the spontaneous imbibition of low-salinity fracturing fluid into oil-wet samples.

Summary: This study aims to investigate the synergistic effects of two nonionic surfactants (Tergitol 15-S-12 and PEG 600) on surface properties, including surface tension, interfacial tension (IFT), and wettability alteration, in chemically enhanced oil recovery (EOR). The optimum composition of the surfactant mixture, determined through surface tension measurement, showed a minimum surface tension value of 30.3 mN/m at a concentration of 225 ppm of Tergitol 15-S-12 and 1 wt % of PEG 600. The surfactant mixture exhibited an ultra-low IFT of 0.672 mN/m at optimum salinity. The wettability alteration study revealed a shift in rock wettability from oil-wet to water-wet region through contact angle observations and X-ray diffraction analysis.

Summary: Investigating the effects of surfactant concentration and droplet size distribution on the rheology of water-in-oil emulsion systems is important for understanding the antiagglomeration properties and finding suitable strategies for flow assurance issues. This study focuses on the rheological characterization of hydrate slurries with a mixed surfactant system and demonstrates that the presence of surfactants can increase the viscosity of the slurries up to a certain concentration, but higher concentrations can reduce viscosity and act as antiagglomerants.

Summary: This study investigated the impact of chain length of saturated hydrocarbons on methane hydrate formation and dissociation kinetics in oil-in-water dispersions. Sodium dodecyl sulfate was used as a surfactant to simulate natural surfactants. The results showed that an appropriate concentration of SDS enhanced the hydrate formation during initial stages, but higher concentrations disrupted the structure of local water. With a fixed SDS concentration, higher carbon chain length accelerated the hydrate formation during initial stages before reaching similar formation kinetics. Higher concentrations and higher alkane content delayed the gas release during dissociation.
