Summary: Mode-coupling theory is utilized to compute the nanoparticle diffusion coefficient in polymer solutions, showing agreement with molecular dynamics simulation data. The theory explains the effects of nanoparticle size, mass, and concentration on the diffusion coefficient and offers a microscopic interpretation of the nonmonotonic dependence of diffusion coefficient on nanoparticle concentration. Both size dependence and mass dependence indicate a significant breakdown of the Stokes-Einstein relation for the model.

Summary: The apparent viscosity of binary particles decreases with the increase in coal powder content, and also drops by half with increase in gas speed. Adjusting gas velocity and magnetite powder content can effectively reduce the apparent viscosity and improve separation efficiency. A modified model for predicting the apparent viscosity of binary particles showed good performance with an overall standard deviation of 13.00% from experimental results.

Summary: This study focuses on developing a strong foam using nanoparticles and surfactants to improve oil recovery in fractured, oil-wet reservoirs. The ECNP/SF foam showed better foamability and stability than SF foam and AOS foam in the presence of oil, with a significantly larger mobility reduction factor. Foam injection into fractured oil-wet cores resulted in significantly higher oil recovery compared to gas injection and conventional AOS foam injection.

Summary: This research investigates a hybrid recovery scheme called TCF-IL co-injection for improving the recovery of extra-heavy oil. Through experiments and simulations, it is found that IL can interact and disperse with asphaltene, leading to reduced viscosity and improved flow properties. The final experimental results show that TCF-IL co-injection significantly increases the recovery of extra-heavy oil compared to TCF injection alone.

Summary: Low salinity water flooding is cost-effective and environmentally friendly, and the addition of nanoparticles and polymers can significantly increase oil recovery. The viscosity of complex chemical slugs can be increased by adding nanoparticles to polymer solutions. Low salinity water requires a lower concentration of polymer to reach the target viscosity compared to high saline formation water. The addition of nanoparticles reduces interfacial tension and contact angle, leading to higher oil recovery in low salinity water. Injection of low salinity water-based complex fluid results in incremental recovery of OOIP compared to low salinity water and conventional formation water flooding.

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.
