Summary: In this study, the extract of the Passiflora plant was used as a natural surfactant for enhanced oil recovery. The optimal critical micelle concentration (CMC) was found to be 4 wt%, which resulted in a minimum interfacial tension (IFT) of 13 mN/m and a contact angle (CA) of 55 degrees on the surface of the carbonate rock. The surfactant solution enabled an additional 7.5% original oil in place (OOIP) to be extracted from the rock plug.

Summary: This study analyzed the performance of three imidazolium-based ionic liquids in reducing the interfacial tension between crude oil and IL solutions under a wide range of salinities. It was found that longer alkyl chain ILs accumulated more at the solution interface under high ionic strength conditions, leading to a greater reduction in IFT. Additionally, under low salinity conditions, longer alkyl chain IL exhibited a lower IFT value in diluted seawater compared to diluted formation water.

Summary: This study demonstrates that the use of ionic liquids can effectively enhance the recovery of heavy oil from oily sludges. Both [C(12)mim] [PF6] and [C(12)mim][Br] ionic liquids show promising results in terms of increasing the oil recovery and improving the sands' hydrophilicity. The high recovery rate and recyclability make the ionic liquids a viable option for enhancing oil recovery.

Summary: The study evaluated the performance of two CEOR agents and found that both chemicals, especially IL, significantly increased oil recovery, while the addition of CTAB to DES solution greatly reduced the oil-brine interfacial tension. The XDLVO theory was used to analyze molecular interactions between the chemicals and dolomite samples, showing a stronger adhesion between the brine and oil-wet dolomite surface.

Summary: In recent decades, low salinity water flooding (LSWF) has gained attention for its effectiveness in oil recovery. However, there is a lack of studies in the literature on the potential of using Ionic Liquids (ILs) as candidates for chemical enhanced oil recovery (CEOR) combined with LSWF. This study evaluates the synergistic effect of ILs with varying chain lengths with low saline ion tuned seawater (ITSW) for enhanced oil recovery from carbonate reservoirs. The analysis shows that ILs demonstrate a better synergistic effect with ITSW, reducing interfacial tension, altering rock wettability, and exhibiting less adsorption density at the reservoir temperature. ILs with the longest chain length ([C12mim] [BF4]) show superior properties and significantly increase oil recovery in low saline ITSW.

Summary: Effective oil displacement from a reservoir requires adequate and properly directed pressure gradients in areas of high oil saturation. This study examines how the pressure-barrier concept limits the size and viscosity of the polymer bank during a polymer flood. Analytical and numerical methods are used to address this issue. The relevance of the pressure modification concept for different conditions and factors is analyzed, and the relation between the pressure-barrier concept and fractures during polymer injection is examined.

Summary: In Chemical Enhanced Oil Recovery (CEOR), various chemicals are injected to mobilize the remaining oil, and microfluidic chips are the best tools to mimic and visualize these microscale processes. The aim of this paper is to review and analyze the current knowledge and efforts in microfluidic for CEOR processes, and discuss potential improvements for future research. Microfluidic methods can address the limitations of conventional CEOR experimentation and provide fast, accurate, and reliable analyses, leading to better understanding of fluid flow and associated mechanisms in porous media.

Summary: Solvent-assisted heavy oil recovery methods, especially the addition of CO2, have shown to reduce the viscosity of bitumen. This study investigates the thermophysical properties of different solvent/bitumen systems and develops a thermodynamic model to predict their behavior. Experimental data indicates that CO2 addition significantly reduces the bitumen viscosity, especially at lower temperatures. A diluent also has a significant effect on the viscosity and density of the mixtures. The developed model successfully predicts the liquid density, C1 solubility, and CO2 solubility with good accuracy.

Summary: In situ solvent-aided thermal recovery processes are efficient and environmentally friendly methods for recovering unconventional oil resources. However, the challenge lies in separating the highly stable water-in-oil emulsion produced, as conventional approaches lead to solvent loss and sample contamination, rendering current solvent content measurement techniques invalid. Therefore, developing analytical techniques for solvent detection without sample dehydration, solvent loss, and contamination is crucial for production surveillance, process optimization, and economic evaluation.

Summary: We present new data on the molecular diffusion coefficient and saturated liquid viscosity of dimethyl ether (DME) in n-decane. Viscosity measurements are modeled using the Pedersen correlation with an AARD of 4.7%. The diffusion coefficient of DME in n-decane exhibits nonmonotonic behavior with respect to pressure, and is modeled using Arrhenius-type kinetics with an overall AARD of 3.38%. Empirical correlations by Siddiqi-Lucas and Hayduk-Minhas are also used to analyze the diffusion data, with AARDs of 7% and 6.2% respectively. The swelling factor of the DME/n-decane binary system is calculated for the diffusion process.

Summary: This study reports a new set of vapor-liquid equilibrium (VLE) data for the solubility of dimethyl ether (DME) in n-decane and DME-saturated liquid density. The experimental data are modeled using the Soave-Redlich-Kwong equation of state (SRK EoS). The results show accurate predictions with Absolute average relative deviation (AARD) values of 4.15% and 0.40% for solubility and DME-saturated liquid phase density, respectively. Additionally, Henry's law constant of DME solubility in n-decane is estimated and correlated with temperature using the van 't Hoff equation.
