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: In this study, a two-dimensional visual model of a fractured-vuggy reservoir was designed based on geological data and injection-production characteristics. Flooding experiments were conducted to investigate the oil-water flow characteristics and residual oil distribution. The results showed that a low injection/high production strategy is the most optimal for achieving maximum oil recovery. The findings of this study provide insights for optimal production in fractured-vuggy carbonate reservoirs and enhance the understanding of oil-water flows within the reservoir.

Summary: Recent studies have shown that adjusting the concentration of SO42- can greatly enhance low-salinity waterflooding in carbonate reservoirs. This study investigated the effects of adding Cr2O72- and C6H5COO- to low-salinity water on enhanced oil recovery, compared with SO42-. The results support the use of Cr2O72- in low-salinity waterflooding, as it helps improve the parameters that are effective in enhanced oil recovery.

Summary: Porosity, permeability, and wettability play crucial roles in the process of oil-water displacement. The study found that the wettability of reservoir rock is negatively correlated with residual oil saturation. It is important to comprehensively evaluate the characteristics of reservoirs before implementing waterflooding or wettability modification techniques during oilfield development.

Summary: This research provides an atomistic perspective on how ions impact the microstructural features of an oil-contaminated calcite surface. It shows that divalent cations, especially calcium ions, play a crucial role in promoting the desorption of oil molecules, while sulfate ions assist in preventing the reabsorption of carboxylate compounds.

Summary: This study evaluates the effects of reaction kinetics and dispersion during low-salinity waterflooding, constructing a mechanistic binary model on carbonate reservoirs. The impact of reaction kinetics on wettability alteration rate is significant, with dispersion having little effect on ultimate oil recovery compared to reaction kinetics. Ultimately, the model reproduces experimental results well and provides insights into the importance of considering comparable Damkohler numbers for field-scale response.

Summary: This study investigates the impact of ion concentration in seawater on the wettability of dolomite rock, with results showing that increasing sulfate concentration up to a certain level leads to increased water-wetness. Additionally, seawater without calcium ions was found to have the best effect on altering the wettability of dolomite rock and increasing oil recovery. The same trend was observed for seawater without magnesium ions.

Summary: Wettability plays a crucial role in the distribution of oil and water in tight oil reservoirs, as well as subsequent oil recovery. This study employs integrated experimental techniques to examine the impact of wettability on micro-distribution and production performance. The results show that wettability alteration affects the oil and water distribution, with strong water-wetting leading to oil droplets and weak oil-wetting resulting in an oil film. The findings highlight the importance of wettability in oil recovery.

Summary: Carbonate reservoirs containing oil reserves can have low recovery rates due to their oil-wet nature, but studies have shown that using low salinity waterflood with modified ionic compositions can increase oil recovery. A new reservoir simulator was developed in this study to model low salinity waterflood in carbonates, considering key geochemical reactions. The model focuses on reactions occurring on water-wet surfaces and at the three-phase contact line, differentiating from previous models that consider reactions on the entire rock surface.

Summary: Foam generated by surfactants can effectively reduce CO2 mobility and improve efficiency in CO2 storage and enhanced oil recovery. Experimental studies are conducted to evaluate the behavior of surfactants in reservoir conditions, and numerical simulations are used to predict the impact of foam. Results show that different surfactants can significantly reduce CO2 mobility and stabilize foam for improved performance in subsurface applications.

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: Transitioning to a sustainable future requires a transformation of energy and environmental technologies. Lab-on-a-chip (LoC) systems can contribute to this transition by studying and developing new processes and materials in areas such as carbon sequestration, hydrogen storage, geothermal energy extraction, bioenergy, critical materials recovery, and water filtration. It is important to engage the LoC community and raise awareness among researchers, industry experts, and policy makers about the potential of LoC approaches in achieving a low-carbon future.
