Summary: Betaine, specifically linear alkylbenzene sulfonate betaine (ASB), has been studied as a surfactant for enhanced oil recovery (EOR). The interfacial properties of ASB were characterized using various methods, and it was found that the difference in interfacial tension had a greater impact on EOR than the interfacial film strength of betaine.

Summary: Traditionally, soil decontamination or enhanced oil recovery procedures involve injecting surfactants and polymers separately to avoid aggregation. Recent studies suggest that in some cases, using interacting polymer and surfactant systems can be more effective for oil recovery, contrary to previous beliefs.

Summary: Research finds that enhanced oil recovery (EOR) polymer systems, such as hydrolyzed polyacrylamide (HPAM) solutions, exhibit shear-thickening in porous media under high flux conditions. To characterize the viscous and viscoelastic behaviors of polymer solutions in porous media, both oscillatory shear rheology based on linear viscoelastic data and extensional rheology based on nonlinear viscoelastic data have been used. However, this study shows that researchers should also consider using nonlinear steady-shear rheology, as the shear-thickening behavior in high-saline HPAM solutions correlates with their mechanical degradation.

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 systematically investigated the imbibition enhanced oil recovery (IEOR) effect of different surfactants in tight sandstone reservoirs. The results showed that the zwitterionic surfactant of erucic acid amide propyl betaine (EAPB) could effectively reduce rock wettability and oil-water interfacial tension (IFT) at low salinity and high temperature, thereby improving imbibition efficiency and IEOR.

Summary: The synthesis of nanosized polystyrene microspheres with good uniformity, strong absorptivity, and controllable size has been reported. The nanofluid can effectively reduce interfacial tension and alter wettability, making it favorable for chemical enhanced oil recovery.

Summary: Chemical surfactant injection is an effective method for Enhanced Oil Recovery (EOR) and the use of nanoparticles can further improve its efficiency. This study investigates the effect of nanoparticle surface hydrophobicity on surfactant efficiency. It is found that the nature of nanoparticles has a significant impact on oil-water interfacial tension and surfactant adsorption inhibition. Hydrophilic nanoparticles show better performance than hydrophobic ones. The results also demonstrate nonmonotonic trends in adsorption assessments, deviating from previous studies.

Summary: The study investigated the Marangoni propulsion of spheres and elliptical disks floating on the air-water interface to understand the influence of particle shape on their motion and stability at moderate Reynolds numbers. Self-propulsion of the particles was achieved by coating them with soap or isopropyl alcohol, creating a surface tension gradient that propelled them forward. It was observed that particle shape and surface tension gradient played a significant role in determining the motion characteristics of the particles.

Summary: The concentration of PAA carrier polymer affects the microstructure and rheological properties of catalyst inks for polymer-electrolyte membrane fuel cells. Both ionomer and PAA stabilize catalyst particles against agglomeration. Increasing PAA concentration enhances particle stability and extensional viscosities of inks, promoting the formation of uniform nanofibers. However, excessive PAA concentration can lead to increased shear viscosities and defective fiber morphologies.

Summary: A new theory is proposed to describe the conformation state of polymer chains in free turbulent shear flows of viscoelastic fluids. The theory shows the existence of minimum and maximum solvent dissipation reduction asymptotes and four different polymer deformation regimes, based on self-similarity arguments and new scaling relations for the turbulent flux of conformation tensor. In addition, analytical solutions for the self-similar transverse profiles of the conformation tensor components are obtained. The theory is validated through excellent agreement with direct numerical simulations employing the FENE-P rheological model.
