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: Shale reservoirs with low porosity and permeability benefit from volume fracturing of horizontal wells for the development of shale oil resources. Recent advances in high pressure forced soaking technology in horizontal wells have shown improved recovery rates through shut-in and imbibition methods, attracting increased attention from researchers. However, the stimulation mechanism and effects of this technology in shale reservoirs remain unclear due to the complexity of shale mineral composition and crude oil composition. Further research is needed to quantitatively characterize the enhanced oil recovery mechanism and the movable lower limit of imbibition in fragmented fluid transport mechanisms.

Summary: Chemical flooding is efficient in releasing trapped oil in porous media. This study explores the use of nanostructured materials to enhance the rheological, phase, and flow behaviors of common CEOR agents, particularly in low-permeable carbonate rocks. Results indicate that dispersing HSNPs in a polymer solution with lower MW can improve the viscosity and non-Newtonian behavior of the solution.

Summary: The flow of CO2 foam in porous media is influenced by the foam texture, or bubble density. In this study, we investigated the real-time dynamics of foam texture at high pressure using a realistic pore network. We found that snap-off is the main foam generation mechanism, and foam coalescence results in large gas channels that decrease the overall foam viscosity. A significant fraction of the CO2 foam remains trapped in the pores, diverting CO2 flow and increasing sweep efficiency. Understanding the evolution of foam texture can help validate numerical foam models and facilitate the implementation of CO2 foam for carbon utilization and storage applications.

Summary: Understanding and predicting non-Newtonian fluid flows in porous media is crucial for geophysical and environmental problems. Through numerical simulations, a predictive function was established between critical Reynolds number (Re-c) and hydraulic shape factor (beta) and power law exponent (n), providing a method to estimate Re-c based on measurable properties via imaging techniques. This mechanistic modelling work sheds light on predicting nonlinear flow for non-Newtonian fluids at the continuum scale by understanding under what conditions significant inertial effects occur.

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.
