Summary: This study investigates the effect of green polymeric nanoparticles on the interfacial tension (IFT) and wettability of carbonate reservoirs for enhanced oil recovery (EOR). The performance of xanthan/magnetite/SiO2 nanocomposites and green materials, such as eucalyptus plant nanocomposites and walnut shell nanocomposites, were compared through spontaneous imbibition tests. The results showed that eucalyptus plant nanocomposites performed better than walnut shell nanocomposites in reducing contact angle (CA) and IFT under different salinities. The EOR of carbonate rocks was improved with eucalyptus plant nanocomposites at specific salinity concentrations.

Summary: This study investigates the effect of the flexible segment of polymer shells and inorganic shells on the dielectric properties. The results reveal that the intermediate polymer shell can limit carrier migration and decrease dielectric loss, while the double-layer structure improves the dielectric constant. Additionally, the energy density of the nanocomposite is significantly enhanced. Therefore, this research provides new insights for the design of hierarchical core-double shell nanoparticles and their derived polymer nanocomposite capacitors for high-energy-density storage applications.

Summary: In this study, a surface acoustic wave (SAW) sensor based on ZnO@MXene hybrid heterostructure was developed for ultrahigh NH3 gas detection under UV illumination at room temperature. The sensor exhibited enhanced frequency response, improved selectivity, low detection limit, short response/recovery times, long-term stability, and robust sensitivity under various relative humidity conditions. These unique NH3 sensing properties were attributed to the enriched functional groups, oxygen vacancies, and excellent charge transfer at the Schottky barrier via band bending. This study provides strategic insights for designing light-activated high-performance SAW-based NH3 sensors in safety assurance and environmental monitoring.

Summary: We have successfully developed SiO2-ZnO nanocomposites with morphological and compositional variation. The biocompatible and UV-active SiO2 spheres deposited by ZnO nanoparticles enable their usage in photocatalysis and antibacterial applications. Detailed investigation revealed the morphological contrast of the nanocomposites and their effects on related energy applications. Photocatalytic degradation of Rhodamine B in water under UV irradiation showed that the optimal nanocomposite with SSs embedded inside ZNPs achieved a 55% dye solution cleaning due to the significant constitution of ZnO and morphological efficacy.

Summary: Introduces a novel organometallic approach to synthesize polymer-coated ZnO nanocrystals, which allows precise control over the polymer/nanocrystal microstructure. The one-pot procedure combines the ring-opening polymerization of E-caprolactone mediated by an organozinc alkoxide initiator and an air-promoted transformation, resulting in quantum-sized ZnO crystals with a core diameter of ca 3 nm coated by poly(E-caprolactone). This method provides the ability to create well-defined hybrid composites for various nanosystems.

Summary: Oil production faces challenges such as limited production from carbonate reservoirs, high costs, and environmental issues. Chemical flooding as an enhanced oil recovery method can increase production by adding surfactants. However, synthetic surfactants are costly and harmful. Researchers have turned to natural surfactants and the use of nanoparticles for enhanced oil recovery. This study extracted a natural surfactant from Cyclamen persicum and optimized its performance with a zinc oxide/montmorillonite nanocomposite. Experimental results showed improved oil recovery with the synergistic usage of the natural surfactant and nanoparticles.

Summary: Nanomaterials, specifically silica-graphene quantum dots (Si-GQDs), have been synthesized and dispersed in water to form nanofluids. These nanofluids exhibit significant reduction in interfacial tension and wettability alteration, leading to enhanced oil recovery from carbonate reservoirs. The experimental results show that the nanofluids formulated with 1000 ppm Si-GQDs in distilled water enable an additional 14.4% oil recovery due to the reduction in interfacial tension and contact angle.

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: Injecting surfactants through cEOR has attracted significant attention in improving oil recovery by altering fluid/rock and/or fluid/fluid interaction. The reduction in interfacial tension (IFT) by adsorption of surfactants on the oil/water interface plays a crucial role in mobilizing trapped oil in porous media. However, the toxicity, high cost, and environmental issues associated with chemical surfactants have led to the search for natural alternatives. This study provides a comprehensive overview of natural surfactant types and their performance in EOR, including the impact of fabrication methods, nanoparticle addition, and salinity. It was found that natural surfactants synthesized from seed oil showed superior performance compared to those extracted from other plant parts, achieving IFT reduction of up to 98% and improving ultimate oil recovery by 2-40% of the original oil in place (OOIP).

Summary: In this study, the reservoir drill-in fluid (RDF) was modified and optimized to improve rheological properties and reduce filtration properties of drilling fluid for horizontal drilling in oil-bearing zones. Controlled polymer degradation proved to be useful in improving processability and cost efficiency of the drilling fluid. Results showed that the addition of a polymer temperature stabilizer (PTS-200) reduced filtration rate by 44.33% and improved rheological properties by 19.31% compared to the standard FLOPRO fluid. The cost analysis revealed that FLOPRO-based drilling fluid had a lower cost of USD 45,000 for horizontal drilling compared to USD 96,000 for NDF and USD 91,000 for SPM drilling fluids.

Summary: Chemical methods have been widely used in oil recovery, but they face challenges in displacing and mobilizing crude oil in porous media. To improve oil recovery and reduce costs, new techniques involving nanotechnology and combined methods can be developed. This study evaluated the wettability alteration of carbonate reservoir rocks using ethanol and methyl ethyl ketone under the influence of synthesized nanocomposites. The results showed that the contact angle decreased with decreasing salinity of the base fluid, and the synthesized nanocomposites had a significant effect on wettability alteration.
