Summary: The results of visual studies show that during the growth of methane and carbon dioxide hydrates in acid and alkali solutions, hydrate films form at the water-gas interface and on the walls of the reactor. Additionally, hydrate films also grow on the free walls of the reactor, possibly formed from wetting water films on the walls. This study also observes the growth of relatively large hydrate agglomerates directly from the reactor walls, potentially facilitated by film transfer of water between the hydrate films and the walls.

Summary: The study explores the influence of silica nanoparticles on the thermal stability of gel foams based on a mixture of fluorocarbon and hydrocarbon surfactants. Results indicate that NP concentration significantly affects the molecular interactions, surface tension, conductivity, and viscosity of the dispersions. Addition of NPs reduces the foaming ability of the solution and slows down coarsening, drainage, and decay of the gel foams under thermal action, ultimately enhancing their thermal stability.

Summary: The study compared the thickness of common black films stabilized by different ionic-nonionic surfactant mixed adsorbed films. It was found that the surface charge density and surface tension have a minor effect on equilibrium film thickness, while specific interactions between imidazolium head groups and BF4- ions in an ion-concentrated environment can lead to irregular behavior in certain systems.

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: The synergism of a mixture of CO2-soluble surfactants composed of 2 ethoxylated amine headgroups with cocoalkyl tails and a nonionic surfactant was quantitatively investigated in this study. The addition of nonionic surfactant to the switchable CO2-soluble surfactant resulted in lower CMC and negative interaction parameters, indicating positive synergism. The optimal surfactants ratio was found to be 8:2, where the foam stability and viscosity increased significantly due to more compact surfactants adsorption layers at the interface.

Summary: In this study, mixed foam dispersions were prepared using hydrophilic silica nanoparticles, siloxane surfactant, and hydrocarbon surfactant. The interaction between surfactant molecules and nanoparticles, as well as the foamability of the dispersions, were analyzed. The thermal stability of the foam was evaluated through foam drainage, coarsening, and volume decay under thermal radiation. The presence of nanoparticles enhanced foam stability and delayed foam coarsening, drainage, and volume decay under thermal radiation. This research provides theoretical guidance for the development of fluorine-free firefighting foams.

Summary: The study investigates and classifies possible analytical solutions for a simplified foam bubble population model by varying injection conditions and kinetic foam generation parameter. The behavior of analytical solutions changes at the transition between two regions, with one region exhibiting traveling waves and the other region showing a sequence of waves: one spreading wave and one traveling wave. These findings differ from previous experiments.

Summary: This study characterizes the wettability of hydrogen and methane, as well as their mixtures, in subsurface reservoirs. The findings show that the wettability behavior of hydrogen and methane is similar, and their mixtures exhibit similar behavior to pure gas systems. The study also validates that under similar conditions, the contact angles of hydrogen and methane bubbles and their mixtures are comparable. This has implications for large-scale subsurface storage systems where buoyancy and capillary forces are the main factors affecting wettability.

Summary: This study investigates the propagation and transport dynamics of nano-sized particles in subsurface water injection. Experimental and modeling approaches are used to explore the dispersion of silica nanoparticles and their agglomeration under different conditions. The results show that nanoparticles remain dispersed at low salinity and within a specific pH range, but agglomeration occurs at higher salinity, pH outside the range, or in the presence of iron ions. Core flood experiments demonstrate stable injectivity with proper pH and salinity of the injected fluid, but injectivity decline still happens and can be explained by a mechanistic model. This study contributes to a better understanding of nanoparticle transport dynamics and modeling prediction in subsurface applications.

Summary: This paper describes how improved oil recovery techniques can reduce the CO2 intensity of oil production by efficient use of injectants. The study shows that the CO2 emissions associated with the injection of chemicals can be significantly reduced by reducing the water cut and improving the utilization factor. Implementing enhanced oil recovery methods earlier can also extend the lifetime of mature fields. CO2 enhanced oil recovery using captured CO2 from gas power plants can greatly reduce overall CO2 emissions of oil.

Summary: Enhancing the recovery from existing oilfields is crucial due to increased energy demand. Polymer flooding, the most frequently used chemical enhanced oil recovery (cEOR) method, has gained growing interest in recent years. This is attributed to the improved properties of polymers at high-salinity and high-temperature conditions and an increased understanding of their transport mechanisms in porous media. Advanced water-soluble polymers and the viscoelastic behavior of polymers in porous media have shown promising results in cEOR applications.

Summary: This study aims to investigate the conditions for the formation of free gas bubbles in CO2-water mixtures and determine the bubble point pressure and rate of bubble formation through experiments and image analysis. The results show that there is a decent agreement between experimental results and theoretical predictions for CO2 in its gaseous state at moderate temperatures, but significant deviations are observed at elevated temperatures. More pronounced differences in bubble point are observed for mixtures starting out at high pressures where CO2 is a supercritical fluid.

Summary: One of the main objectives of foam flooding enhanced oil recovery (EOR) is to mobilize remaining oil in the reservoir after primary recovery and water flooding. This study investigates the impact of Newtonian and non-Newtonian viscosifying agents on foam flooding, and explores the potential use of glycerol as an economically and ecologically viable alternative to polymers. The experiments reveal that glycerol can achieve similar levels of mobility reduction as polymer solutions, and even reaches maximum mobility reduction faster.

Summary: An understanding of how CO2 foam flows through a reservoir rock is beneficial for subsurface applications such as enhanced oil recovery and CO2 storage. This study investigates the behavior of supercritical CO2 foams flowing through a high-permeability Indiana Limestone by conducting core flood experiments. The foaming behavior and concentration response of two surfactants, a betaine and a sultaine, were studied and compared with N2. The results show that CO2 exhibits better foaming behavior at high foam qualities, while N2 generates stronger foam at low foam qualities.
