Summary: The efficacy of low salinity water flooding depends on the wettability of the system, with seawater being optimal for oil-wet and intermediate-wettability systems. Sequential flooding with seawater followed by diluted seawater yielded the highest displacement efficiency of 88% in a water-wet system. Additionally, low-salinity brine followed by sulfate showed better performance in a water-wet environment compared to oil- and intermediate-wettability systems.

Summary: Combined low salinity water (LSW) and polymer (LSP) flooding is an effective method for enhancing oil recovery. The injection of LSW can alter the wettability and improve oil recovery in samples without clay particles. Secondary LSW injection can increase the oil recovery by 8% compared to secondary synthetic seawater (SSW) injection in oil-wet samples, and tertiary LSW injection or LSP flooding after secondary SSW injection can achieve even higher oil recovery in oil-wet samples.

Summary: The low salinity water flooding (LSWF) technique is cost-effective and environmentally friendly, but its mechanisms are not yet clear. Recovery in LSWF depends on fluid/fluid and rock/fluid interactions. This study investigated both interactions and found different optimal conditions for improved oil recovery. Rock/fluid interaction showed an incremental recovery of 14%, while fluid/fluid interaction showed an incremental recovery of 7% over simple seawater injection. Results highlight the importance of considering both interactions and wettability alteration in LSWF design.

Summary: The injection of low-salinity water into carbonate oil-reservoirs can alter the geochemical equilibrium and surface wettability of the reservoir rocks. Experimental results show that mineral dissolution and the precipitation of new secondary phases play a key role in the geochemical changes during low-salinity water flooding. The proposed geochemical pathway accurately describes the experimental observations and provides valuable insights into enhanced oil recovery methods.

Summary: Low salinity water flooding is a method used in the EOR process to change the surface wettability and reduce interfacial tension. This study investigates the effects of ions on the surface wettability of shale rocks and the interfacial tension of brine/oil. It is found that decreasing the concentration of monovalent ions changes the wettability of shale from neutral wet to weakly water wet, while decreasing the concentration of divalent ions induces an oil wet system. Time and salt ion concentration have significant impacts on shale wettability and interfacial tension.

Summary: This study examines the pulse-like behavior in coarse grid models of Low Salinity Waterflooding (LSWF) and analyzes the stability and causes of the pulses. The numerical solution was found to be stable despite the apparent growth of the pulses over time. The formation and propagation of the pulses are explained in terms of modeling wettability changes and their impact on relative permeability.

Summary: This study investigates the wettability alterations through imbibition/flooding and their synergy with interfacial tension (IFT) for alkalis, nanoparticles, and polymers. It demonstrates the influence of the oil total acid number (TAN), chemical agents, and reservoir mineralogy on fluid-fluid and rock-fluid interactions. A laboratory evaluation workflow combining various assessments is used to evaluate wettability alteration, IFT changes, and recovery. The study provides novel data on the synergy of IFT, Amott imbibition, and core floods for the studied chemical processes.

Summary: Foam-assisted deoxidized-air flooding is a promising technique for improving oil recovery in low-permeability oil reservoirs. This study conducted laboratory experiments and field pilot analysis in a low-permeability oil reservoir in China to investigate the displacement mechanism of foam-assisted deoxidized-air flooding. The results showed that the gas-liquid ratio had different effects on oil recovery at different water cut stages, and the differences in oil recovery were linked to changes in the displacement mechanism.

Summary: Understanding the interaction between rock and fluid is crucial for the success of enhanced oil recovery (EOR). However, the presence of calcium sulfate minerals, such as anhydrite, significantly affects EOR methods. The effectiveness of oil recovery techniques depends on the distribution and interaction between anhydrite and fluids. This review highlights the factors influencing anhydrite dissolution during EOR and discusses the implications for different EOR fluids. It also examines the prospects and challenges of using various EOR applications in anhydrite-containing reservoirs.

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.
