“…Silica NPs are cost-effective, relatively easy to manufacture, as well as safe to use. 27 Silica NPs are commonly used to reduce the polymer adsorption on rock surfaces. These NPs possess a large surface area and can be modified with surface functional groups that can interact with polymer molecules and prevent their attachment to the rock surface.…”

Polymer flooding improves reservoir tertiary recovery, especially in highly heterogeneous formations containing viscous crude oils. Because polymer adsorption can result in a significant loss of the injection fluid viscosity, polymer adsorption should be controlled by modifying the properties of the system. Alkali is widely used to improve the repulsive forces between the polymer and sand grains by making the rock surface more negative. Nanoparticles may also be effective to control polymer adsorption as a result of their large surface area and ability to interact with polymeric chains. Despite the positive synergy between nanoparticles and polymers, the research on the utilization of nanoparticles in minimizing polymer adsorption is limited with very few studies conducted under real field conditions. To improve oil recovery from a Kazakhstani oilfield, field A, by utilizing a previously designed optimum polymer concentration, this study aimed at controlling polymer adsorption with application of silica nanoparticles (NPs) and NaOH alkali. For this purpose, static and dynamic adsorption tests were performed, followed by oil recovery tests utilizing the optimum combination. The stable chemical concentrations for polymer, alkali, and nanoparticles were determined on the basis of aqueous stability and zeta potential measurements. Static adsorption results showed a noticeable effect of both silica NPs and NaOH alkali on lowering polymer adsorption. However, alkali was less efficient for longer contact durations with the rock. Silica NPs also facilitated around 18% reduction in polymer dynamic adsorption. At the same time, alkali was ineffective, leading to a 5% increase in polymer dynamic adsorption. Polymer–nanoparticle (P–NP) flooding as an enhanced oil recovery technique was successful, achieving a total recovery factor of around 95%, where incremental recovery of the remaining oil was 5% higher than the standalone polymer flooding scenario. On the basis of the results, it is recommended that the polymer flooding plan for field A can be improved by incorporating the findings of this study.

“…There has been a growing interest in the application of particle emulsifiers for stabilizing emulsions, particularly those composed of hard inorganic particles like titanium dioxide [3] and silicon dioxide [4]. However, these particles often suffer from limited biodegradability and biocompatibility, which restricts their use in the food and pharmaceutical industries.…”

Biocompatible particle-stabilized emulsions have gained significant attention in the biomedical industry. In this study, we employed dynamic high-pressure microfluidization (HPM) to prepare a biocompatible particle emulsion, which effectively enhances the thermal stability of core materials without the addition of any chemical additives. The results demonstrate that the HPM-treated particle-stabilized emulsion forms an interface membrane with high expansion and viscoelastic properties, thus preventing core material agglomeration at elevated temperatures. Furthermore, the particle concentration used for constructing the emulsion gel network significantly impacts the overall strength and stability of the material while possessing the ability to inhibit oxidation of the thermosensitive core material. This investigation explores the influence of particle concentration on the stability of particle-stabilized emulsion gels, thereby providing valuable insights for the design, improvement, and practical applications of innovative clean label emulsions, particularly in the embedding and delivery of thermosensitive core materials.

With the continuous exploitation of global oil and gas resources, the focus of oilfield development has gradually shifted to low‐permeability and tight reservoirs. Nowadays the nanofluid has become one of the most important methods to enhance oil recovery in low‐permeability reservoir since the wettability and fluid flow characteristics can be changed as hydrophobic nanoparticles are adsorbed on the surface. In this study, we focus on the fluid slip characteristics feature of nanoparticles adsorbed with different adsorption degrees through molecular dynamics methods. Our results show that the adsorption of hydrophobic nanoparticles on the wall induces a velocity slip effect. The fluid flows in a Cassie state in the micro‐channel, with a significant increase in density, velocity, and slip length. In addition, the velocity in the mainstream area is significantly greater than that near the wall. The fluid flow rate within the pore channel is maximized and the most optimal adsorption degree is around 65.08%. Meanwhile, this study provides not only of great significance for the microscopic mechanism of pressure reduction and injection enhancement technology by nanoparticles adsorbed, but also an efficient method in enhance oil recovery in low‐permeability oil reservoirs.
