Summary: Nanofluids, particularly silica, show promise in enhancing oil recoveries with economic and environmental acceptability. However, understanding the two-fold impact of parameters like concentration and salinity is key to optimizing recovery mechanisms and stability. Experiment results indicate that 0.05 wt. % silica nanofluid concentration is optimal for enhanced recovery and stability under high salinity conditions.

Summary: The main objective of this study is to develop a novel green nanofluid from Sapindus Saponaria for its application in enhanced oil recovery (EOR) processes. The study successfully extracted green active compound (AGC) from soapberry Sapindus Saponaria and mixed it with bio-ethanol and commercial surfactant at a low concentration to form a bio-nanofluid. The AGC was characterized and the performance of silica-based nanoparticles was evaluated. The adjusted system showed excellent performance in coreflooding tests, indicating an increase in crude oil production with the best bio-nanofluid.

Summary: This study employed Design-Expert Software tool to modify the surface of pure Halloysite nanotube (pHNT) with Cerium and Silver nanoparticles for enhanced oil recovery (EOR). The modification improved the chemical properties of the pHNT and significantly reduced the interfacial tension (IFT) in the brine/oil system. The optimization process yielded m-HNT with improved wave numbers, crystallography, morphology, and thermal stability. The results suggest that modifying pHNT with Ce/Ag is important for achieving good IFT reduction effect in EOR.

Summary: One efficient method to extract hydrocarbons is to use nanoparticles for wettability alteration. This study investigates the impact of synthesized Fe3O4, SiO2, and Fe3O4/SiO2 nanomaterials on wettability alteration and asphaltene removal in an oil/water system at two temperatures. The results show that nanoparticles can reduce surface energy and oil area fraction, and the optimal condition for wettability alteration is achieved with 0.075 wt% C1000 nanoparticles at 80°C. This study provides useful insights for controlling asphaltene precipitation and enhancing oil recovery in the petroleum industry.

Summary: This study investigated the performance of different types of surfactants on the surface activity, emulsion size, and surface charge of five oil samples. The effects of various parameters on the interfacial tension of crude oil/surfactant solutions were comprehensively analyzed. The results showed that the properties of the surfactants, crude oil type, and ionic strength influenced the interfacial tension, surface charge, and microemulsion size, but not in a straightforward manner. Among the surfactants considered, the cationic surfactant showed the lowest dependency on the crude oil type, while the non-ionic surfactant showed the highest dependency. CTAB cationic surfactant exhibited the most efficient performance with a microemulsion size of 102 nm and surface charge near the isoelectric point.

Summary: The interfacial properties of conventional and functional modified nanofluids, including tension and contact angle, were experimentally investigated. The results showed that the surface tension of both types of nanofluids decreased with increasing nanoparticle concentration and temperature. The contact angle was affected by the surface roughness of copper plates as well as the nanoparticle loading. The surface tension and contact angle of conventional nanofluids decreased with increasing surfactant concentration.
