Summary: This study investigates the co-current spontaneous imbibition in two-dimensional reservoir formations. The anisotropic ratio between the vertical and horizontal intrinsic permeability significantly affects the recovery dynamics. Cross-flow behavior leads to early water breakthrough and bypassing of oil/non-wetting phase. The onset of forced imbibition is regulated by the mean pressure distribution of the underground formation.

Summary: Fluid flow in naturally fractured reservoirs is complex and heterogeneous, and understanding fracture-matrix interactions is crucial. Fluid movement between fractures and matrix occurs through spontaneous imbibition, which can be affected by wettability. Low-salinity water injection is considered as an effective enhanced oil recovery approach for fractured and non-water-wet carbonate rocks. This review summarizes experimental and numerical studies on the imbibition process and highlights the need for further research on wettability alteration and simulation models for co/countercurrent flows in naturally fractured reservoirs.

Summary: In this study, a new analytical model of spontaneous imbibition height in low-permeability reservoirs was derived, considering various factors such as effective viscosity, surface roughness, slip, and gravity effects in a single tortuous capillary tube. The analytical model showed good agreement with experimental results from literatures in typical low-permeability core samples. Sensitivity studies indicated that parameters like surface fractal dimension, effective viscosity, and contact angle have an inverse relationship with imbibition height on rough surfaces, while pore radius, interfacial tension, and slip length have a proportional relationship with imbibition height. Neglecting slip effects may lead to underestimation of imbibition height in nanopore sizes. The presented models provide clear physical interpretations for each parameter affecting imbibition height performance.

Summary: This research systematically analyzed the physical properties and thin-section images of tight sandstone reservoirs and examined the efficiency of spontaneous imbibition through core tests. The results showed that quartz and feldspar predominantly contributed to mineralogy, and low brine salinity, high oil viscosity, and high interfacial tension were associated with strong spontaneous imbibition ability and fast process. High interfacial tension was identified as the dominant controlling factor in this field. Furthermore, the parameter simulation model established using the dimension reduction method provided a reliable prediction of spontaneous imbibition efficiency.

Summary: Formation damage caused by the injected working fluid reduces the production of coalbed methane (CBM) wells. The traditional method to evaluate the severity of formation damage focuses on permeability, but neglects the damage caused by the pure liquid phase of the working fluid on the gas transport process of CBM. Therefore, a multiscale working fluid filtrate damage evaluation method was proposed in this study, which demonstrated significant damage to the desorption-diffusion and seepage ability of CBM by pure liquids with different pH values and salinities.

Summary: Formation damage caused by the injected working fluid affects the production of coalbed methane wells. The severity of damage to coal has been evaluated using permeability as a parameter, but less attention has been given to the formation damage from the liquid phase of the working fluid. In this study, a multiscale working fluid filtrate damage evaluation method is proposed to evaluate high-rank coal in China. The results show that different liquids significantly damage the desorption-diffusion and seepage ability of coal, and the damage severity in the seepage process is higher. Effective channel reduction and resistance increase in gas transport are the mechanisms of working fluid filtrate-induced formation damage.

Summary: Large-scale hydraulic fracturing is crucial for efficient shale oil production, but the mechanisms of fracturing fluid flow in shale micropores and the impact of shale microstructure and physical properties are not well understood. This lack of understanding hinders the optimization of fracturing flowback and limits shale oil recovery enhancement. This study analyzes the characteristics of shale pores using SEM and XRD experiments, finding multiple pore types including organic pores, brittle mineral pores, and clay pores. The study investigates the influence of cross-section shapes on capillary force and analyzes the dynamics of imbibition in different pore types. A shale semi-analytical solution that considers imbibition time, fluid properties, pore cross-section shapes, tortuosity, and forced pressure is established using a shale multi-pores physical model and fractal theory.

Summary: This study reports the production of a hybrid nanostructure based on iron nanoparticles on montmorillonite nanoclays as an oxygen scavenger and barrier additive in polymeric packaging materials. The interactions between iron nanoparticles and montmorillonite nanoclays were demonstrated to effectively limit particle growth and agglomeration, resulting in smaller nanoparticles with higher specific surface area. Different solvent and primary cation types showed different preferences in interacting with the nanoclays, leading to different site selection. The results suggest the possibility of tailoring the properties of the hybrid nanoparticles for specific applications.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.
