Summary: A multi-functional composite fracturing fluid system HC-5 was constructed in this study to enhance the oil recovery in low permeability heavy oil reservoirs. The system combines fracturing, viscosity reduction, wettability change, and interface modification. The evaluation results show that the improvement of the water-oil mobility ratio is more significant than the reduction of viscosity in enhancing oil recovery. Furthermore, it is not recommended to blindly pursue extremely low interfacial tension, and the synergistic effects of various factors should be considered for optimal results. The field test also demonstrates a significant increase in the primary production of wells using this fracturing fluid system by 20-25%.

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: Studies have shown that a combination of interfacial tension reduction and wettability alteration is the main mechanism for increased oil recovery. Residual oil is divided into five categories based on location and form, and the effect of IFT reduction and WA varies on different residual oil categories.

Summary: A new Gemini hybrid surfactant DFCS was developed to enhance the salt resistance and interface activity of fluoro-nated surfactants. It can be used as a cleanup additive in fracturing and an active agent in water flooding for shale and superlow-permeability sandstone reservoirs. DFCS exhibited lower interface tensions than current fluorinated surfactants at high salinities, showed temperature resistance below 70 degrees Celsius, and had large molecular area and strong spontaneity in micelle formation.

Summary: Solid-liquid interfacial free energy (gamma SL) is difficult to measure, but this study presents a direct experimental measurement method for different solid materials. The results show that water-metal adhesion is 80% stronger than the cohesion energy of bulk water, which is consistent with previous quantum chemical calculations.

Summary: A bifunctional imidazolium-based ionic liquid surfactant was synthesized and its surface-active, emulsification capacity, and CO2 capture performance were investigated. The synthesized surfactant showed characteristics of reduced interfacial tension, emulsification, and CO2 capture. The surface-active and emulsification capacity improved with increased alkyl chain length. The absorption capacity for CO2 reached 0.48 mol per mol of ionic liquid surfactant. This study provides theoretical support for further research and application of ionic liquid surfactants in carbon capture and utilization storage-enhanced oil recovery (CCUS-EOR).

Summary: This study explores the use of novel nanostructure multicationic surface active ionic liquids (MSAILs) as alternatives to traditional surfactants in enhanced oil recovery (EOR). A new MSAIL, [(C4benzim)3TA][Cl3], was synthesized economically using a two-step method. Characterization techniques such as FT-IR, NMR, XRD, TGA, DTG, SEM, and DLS were used. The effects of the product on interfacial tension, micellization, emulsification, and wettability alteration of the oil-water system were investigated.

Summary: This study investigates the wettability alterations through imbibition/flooding and their synergy with interfacial tension (IFT) for alkalis, nanoparticles, and polymers. It demonstrates the influence of the oil total acid number (TAN), chemical agents, and reservoir mineralogy on fluid-fluid and rock-fluid interactions. A laboratory evaluation workflow combining various assessments is used to evaluate wettability alteration, IFT changes, and recovery. The study provides novel data on the synergy of IFT, Amott imbibition, and core floods for the studied chemical processes.

Summary: This study investigates the effect of different surfactants on changing rock surface tension and interfacial tension, as well as their impact on enhanced oil recovery in tight oil reservoirs. The results show that fluoride FC-1 and GS surfactant have the potential to alter wettability and reduce interfacial tension. The study reveals that changing rock wettability is more favorable for oil recovery in tight sandstone oil reservoirs than reducing interfacial tension.

Summary: This study investigated the effects of adding anionic surfactants on the flow characteristics of wet sand particles and the mechanical properties of silicate-bonded sand. The experimental results showed that adding a small amount of anionic surfactants can significantly improve the flowability of wet particles, but it also reduces the flexural strength of the bonded sand.

Summary: This study investigates the adsorption behavior of a potentially identified non-ionic surfactant on reservoir rock surfaces. The adsorption is found to be affected by mineral composition and surface area, with the Langmuir isotherm model and pseudo-second-order kinetics providing the best fit for the data. Additionally, the use of hydrophilic nanoparticle-surfactant flooding shows promise in improving oil recovery mechanisms.

Summary: This study investigates the adsorption behaviors of surfactants in sandstone reservoir rocks with different amounts of carbonate cement/minerals and their impact on wettability alteration under low-salinity conditions. The results show that the mineralogy of sandstone reservoir rocks, especially carbonate minerals, affects the brine-rock interactions, including wettability alteration and surfactant adsorption. Low salinity surfactants can positively alter the wettability of both rock types to water-wet conditions, with the most favorable wettability alterations achieved with cationic surfactant solutions.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

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.

Summary: This study aims to develop a nano-biofungicide comprising of volatile essential oil molecules to enhance its efficacy in the field of agriculture through easily scalable green synthesis technique. The nano biofungicide was prepared through one pot hot melt ultrasonication technique with easy water dispersibility and long term stability. The physico-chemical analysis revealed that, nano bio-fungicides were amorphous sphere-shaped nanoparticles with low melting point. The encapsulation efficiency of major components of essential oil was determined, and it was found that they followed Higuchi model of release kinetics. The essential oil loaded nanostructured lipid carrier showed significantly higher mycelial growth inhibition compared to pure essential oil, indicating enhanced bio-efficacy.
