Summary: This study investigates the effects of imidazolium nano GSAILs, salts, and pH on the crude oil-water system. Results show that medium and long alkyl chain GSAILs significantly reduce interfacial tension and critical micelle concentration. Furthermore, alkaline conditions enhance emulsification with imidazolium nano GSAILs.

Summary: Interfacial tension (IFT) and wettability are important factors in determining oil/water distributions and hydrocarbon production in reservoirs. This study investigates the effects of ionic liquids (ILs) on IFT and wettability in sandstone reservoirs. The results show that ILs can lower alkane-water IFT and influence the interaction between oil droplets and the quartz surface. Molecular dynamic simulations indicate that ILs can reduce the interaction energy between octane droplets and the quartz surface. These findings have promising applications in enhanced oil recovery and oil contamination removal.

Summary: This study investigates the effects of a benzimidazolium cationic GSAIL and SDS surfactants on the properties of crude oil-water interface. Synergistic effects were observed in reducing interfacial tension (IFT), promoting emulsification, and altering wettability. The attractive interaction between the cationic GSAIL and the anionic SDS contributes to the remarkable performance.

Summary: In recent years, the use of smart water and surfactants to enhance oil recovery in carbonate reservoirs has gained significant attention. This study investigated the impact of various salts in smart water and two surfactants (CTAB and SDS) on wettability alteration and interfacial tension (IFT) in carbonate rock. Micromodel and core flooding tests were conducted to evaluate the oil recovery under different injection schemes. The results showed that CTAB or SDS in seawater (SW) had a stronger contact angle reduction effect compared to smart water. Increasing the concentration of SO42- and removing Na+ from SW resulted in more water-wet states. Divalent cations (Mg2+ and Ca2+) showed better performance in improving oil recovery. The combination of SW and surfactants had a more positive effect on boosting oil recovery compared to smart water flooding. The first-order injection scheme was more effective than the second-order injection scheme. SW + CTAB and SW + SDS in tertiary injection increased the oil recovery to about 59% and 57%, respectively, with CTAB being more effective than SDS.

Summary: Ionic liquids (ILs) have been widely used but difficult to purify and recycle due to their hydrophilicity. This study calculated the free energy of water crossing ILs and found a linear relationship between surface tension and water content at the interface. The nonlinear change of surface tension with total water content was explained by investigating the interface structure with water content.

Summary: The study investigated the impacts of low salinity waterbased fluids and a non-ionic surfactant on wettability alteration, interfacial tension changes, and fluid pH in Asmari formation carbonate and sandstone reservoirs. Experimental results showed that the calcium chloride dihydrate solution with surfactant had the most beneficial effects on improving oil mobilization in both reservoir samples. Glass micro-model fluid-flow experiments confirmed the efficacy of calcium chloride dihydrate in achieving higher ultimate oil recovery compared to other solutions tested.

Summary: Experimental measurements were carried out on the physical properties of aqueous tetrabutylammonium-based ionic liquids, showing that density and surface tension increase with higher concentration of [TBA][Br], while dynamic viscosity increases with increasing IL concentration. The interaction between [TBA][Br] and water was found to be stronger compared to other ILs, resulting in unique trends seen in the physical properties. Additionally, the experimental data was satisfactorily correlated and compared with the calculated model.

Summary: This study synthesized a hybrid material of TPA-POP and UiO-66-NH2 and evaluated its adsorption capacity. The results showed that the hybrid material achieved complete adsorption of BB41 dye within 60 minutes. The pseudo-second-order model provided the best fit for the kinetics, and the Langmuir isotherm yielded a maximum equilibrium adsorption of 260.7 mg/g. Furthermore, N2 adsorption/desorption isotherms indicated a reduction in BET surface area due to hydrogen bonding between TPA-POP and UiO-66-NH2. The adsorbent demonstrated recyclability without significant activity loss.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
