Summary: Wettability alteration from oil-wet to water-wet is proposed as a mechanism for enhanced oil recovery. However, in a specific crude-oil/brine/rock system, low salinity water flooding was found to be ineffective. Chemical EOR, by adding a cationic surfactant to the injecting brine, was suggested as a hybrid technique to improve oil recovery in such cases. Contact angle, zeta potential, and IFT tests, as well as dynamic micro-model tests in fractured porous media, were conducted to study the interactions and displacement mechanisms. Experimental results showed that the surfactant absorbed on the oil/brine interface, leading to detachment of oil droplets and enhancement of oil recovery.

Summary: A low salinity surfactant (LSS) system was developed to enhance the performance of immiscible surfactant alternating gas/CO2 (SAG) flooding in sandstone reservoir cores. LSS solutions showed positive impacts on various mechanisms responsible for enhanced oil recovery (EOR), including reducing surface and interfacial tension, altering wettability, improving CO2-foam stability, and decreasing surfactant adsorption.

Summary: The study examined the adsorption behavior of natural saponin surfactant on carbonate rock outcrops, showing that saponin adsorbed less than ionic surfactants due to weaker hydrogen bonding rather than electrostatic interactions. Compared to other nonionic surfactants, saponin had greater retention attributed to its molecular structure with more terminal functional groups. These findings are valuable in surfactant selection for EOR, highlighting the potential of natural and environmentally friendly surfactants.

Summary: Surfactants are commonly used in carbonate hydrocarbon reservoirs for enhanced oil recovery. This study focuses on injecting a single component surfactant to mitigate the risk of chromatographic and phase separation. The results show that the single component surfactant alone can achieve high oil recovery without the need for additional cosolvents or cosurfactants, and injecting a polymer can further improve the oil recovery.

Summary: This study investigates the synergistic effect of aluminum oxide nanoparticles on the efficiency of sodium dodecyl sulfate as an anionic surfactant in surfactant flooding. The results show that the nanoparticles significantly enhance the reduction of interfacial tension between the aqueous phase and crude oil, and reduce the adsorption density of the surfactant onto sandstone rock. Additionally, the addition of nanoparticles improves the oil recovery by approximately 15%.

Summary: This study examines the synergistic effect of sodium dodecyl sulfate (SDS) as an anionic surfactant and aluminum oxide (Al2O3) nanoparticles on the efficiency of surfactant flooding. The results show that the presence of nanoparticles significantly enhances the reduction of interfacial tension between the aqueous phase and crude oil and decreases the adsorption density of SDS onto sandstone rock. The study also finds that there is an optimal concentration of Al2O3 nanoparticles that maximizes oil recovery.

Summary: The surfactant EOR is considered a promising approach for enhancing oil recovery due to the changing energy supply and demand and the non-renewable nature of world oil reservoirs. However, surfactants face challenges such as high adsorption, low stability, and poor performance in harsh conditions like high temperature, high salinity, and dense carbonate rocks. There is currently no established procedure or framework for systematically selecting the best surfactant for EOR in dense carbonates.

Summary: This study explores the impact of wall roughness on mass transfer in a microtube with porous wall. The effects of corrugation amplitude and wavenumber on mass transport are assessed using perturbation approximations and numerical analysis. It is discovered that solute mass flux can be enhanced by 10% through appropriate tuning of corrugation amplitude. These findings contribute to a better understanding of mass transport in porous-walled, rough microtubes, which is crucial for applications such as micromixers and targeted drug delivery.

Summary: It is important to study the microstructure of kerogen and its effect on CH4 adsorption characteristics. The microstructure of core and outcrop kerogen samples from Longmaxi Shale in SW China were compared for the first time in this study using various experimental techniques. Significant differences in chemical structure between the two samples were identified. The CH4 adsorption capacity of the core sample was found to be higher than that of the outcrop sample, indicating the influence of kerogen microstructure on CH4 adsorption behavior. Therefore, core samples are recommended for accurately evaluating the adsorbed gas content in shale gas reservoirs.

Summary: This study examines the adsorption capacity of Berea sandstones with varying wettability states for hydrogen and hydrogen-methane mixture. The results show that the addition of CH4 increases the gas uptake, indicating a strong affinity of CH4 for aged rock. The adsorption capacity of the H2-CH4 mixture increases when rock samples are exposed to crude oil. The models used to describe the adsorption characteristics suggest multilayer adsorption on the rock surface.

Summary: Studied tracer dispersion in stratified porous media and found that the hydrodynamic coupling between two layers leads to the tensorial nature of dispersion and advection. The obtained dispersion tensor and advection are not symmetric unless both layers have similar thickness, porosity, and molecular diffusion. The study also revealed the presence of dispersion barrier, uphill dispersion and advection, and osmotic dispersion during tracer transport in stratified porous media.
