Summary: Efficient demulsifiers with varying viscosities were evaluated for their demulsification potential on asphaltene stabilized crude oil emulsions. The demulsifiers showed better performance at ambient conditions in demulsifying emulsions formed from distilled water, while the higher viscosity demulsifier achieved a lower water removal. Seawater hastened demulsification. In the presence of salts, the demulsifiers demonstrated excellent demulsification and the performance varied depending on the type of salt. Injection of demulsifiers reduced the viscosity and shear stress of the emulsion, with the highest reduction observed in the lower viscosity demulsifier. A demulsification mechanism was proposed based on the analysis of optical microscopic images.

Summary: Surfactant adsorption is a significant challenge for cEOR techniques and it depends on the presence of silicate and clay minerals in carbonate outcrops. The higher the impurities, the higher the surfactant adsorption. The addition of a novel adsorption inhibitor, methylene blue, dramatically reduced the surfactant adsorption on carbonate outcrops. Curve fitting analysis showed that the Redlich-Peterson model described the adsorption isotherm well, while the pseudo-second-order model described the adsorption kinetics accurately.

Summary: Surfactant flooding is an effective method to enhance oil recovery, but the loss of surfactant due to adsorption on reservoir rocks hinders its efficiency. This study investigates the use of formic acid to reduce the adsorption of cationic gemini surfactant on carbonate rocks. The results show that the addition of 1% formic acid dramatically reduces the surfactant's adsorption on carbonate rocks. It is believed that the carboxyl group released by the formic acid-rock reaction shields the surfactant from the rock surface, resulting in lower adsorption. This study provides a low-cost option for reducing cationic surfactant adsorption on carbonate rocks.

Summary: Wettability alteration is an important mechanism in enhancing oil recovery methods. However, it depends on various parameters such as aging time, aging temperature, core nature, and oil properties. This paper compiles relevant literature to investigate the effect of these parameters on wettability alteration and finds the shortest and most reliable aging time for different rock-oil systems. Results show that carbonates generally require shorter aging time (1-7 days) compared to sandstones (14-21 days).

A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.
