Summary: This study investigated the performance of different types of surfactants on the surface activity, emulsion size, and surface charge of five oil samples. The effects of various parameters on the interfacial tension of crude oil/surfactant solutions were comprehensively analyzed. The results showed that the properties of the surfactants, crude oil type, and ionic strength influenced the interfacial tension, surface charge, and microemulsion size, but not in a straightforward manner. Among the surfactants considered, the cationic surfactant showed the lowest dependency on the crude oil type, while the non-ionic surfactant showed the highest dependency. CTAB cationic surfactant exhibited the most efficient performance with a microemulsion size of 102 nm and surface charge near the isoelectric point.

Summary: Wettability alteration is a key mechanism for enhanced oil recovery during low salinity water flooding, but the role of oil type in this process is still not well understood. This study investigated the contact angle, interfacial tension, and zeta potentials for various rock/brine/crude oil systems. The results showed that the contact angle behavior varied with oil type and salinity, and a comprehensive model was successfully used to predict the contact angle. The study also revealed that interfacial tension and electric double-layer forces play important roles in controlling wettability behavior in different rock substrates.

Summary: The chemical composition of the aqueous phase is important in water-based enhanced-oil recovery processes. The ionic profile of the aqueous phase affects the snap-off response of a crude oil-brine system. Solutions with higher ionic strength form more rigid interfaces, while solutions with polyvalent anions in the low-salinity regime produce more viscoelastic interfaces at faster rates. There is an excellent correlation between the relative stability of the interfacial film predicted in liquid bridge tests and the ratio of interfacial tension and interfacial elastic modulus.

Summary: This study investigates the fluid-fluid interaction between low salinity water and microbial enhanced oil recovery (MEOR) and demonstrates that the injection of GeoBacillus stearothermophilus bacteria can reduce interfacial tension in both acidic and basic oil. The presence of different salts, especially CaCl2, affects the performance of biosurfactants. Furthermore, the combination of low salinity water and bacteria results in lower interfacial tension compared to using them individually.

Summary: This paper focuses on the mechanism of surfactant production enhancement in the reservoir during the exploitation of tight reservoirs. It provides a detailed description of the factors affecting the stripping of crude oil by different surfactants, as well as the two spontaneous imbibition mechanisms of the surfactant. The results show that the particle size of emulsion, the interfacial tension between the surfactant and oil, and the wettability change all play important roles in the efficiency of oil stripping and the imbibition process. The study also utilizes X-ray computed tomography to determine the surfactant imbibition distance of different permeability types of cores. These findings contribute to a better understanding of enhanced oil recovery by surfactants and have significant implications for the exploitation of tight reservoirs.

Summary: The study investigated the dynamic interfacial tension (IFT) between oil and VES solution using a porous glass micromodel, showing that IFT increases with shear rate and then reaches a plateau. The findings indicate that the IFT of high concentration VES can be reliably estimated during multiphase flow without the need for separate experiments and waiting for equilibrium to be reached.

Summary: The salinity of upper seashores can surpass seawater due to evaporation, potentially inhibiting the biodegradation of oil spills. Under high salt concentrations, the activity of hydrocarbon-degrading bacteria was significantly inhibited, especially for alkanes. This study suggests that occasional irrigation of oiled supratidal zones could support remediation processes by promoting biodegradation.

Summary: This paper examines the time-varying conditional higher moments of daily returns on WTI crude oil futures using the GJR-GARCH model with Gram-Charlier expansion. The empirical results show significant time variations in conditional skewness and kurtosis, and suggest the advantage of models with dynamic higher moments in out-of-sample VaR forecasting.

Summary: The motion behaviors, rheological properties, and mechanical properties of a wax crystal mesoscale force chain network in gelation of waxy crude oil were studied experimentally and numerically. The relationship between the structure of the force chain network and the motion behaviors of the wax crystals and its rheological properties was analyzed. Results showed that as the temperature decreased, the motion velocity of wax crystals decreased, average coordination number increased, and viscosity of waxy crude oil increased. A complex and stable force chain network was observed during gelation.

Summary: The study explored the surface-free energies on carbonate surfaces in contact with different aqueous solutions and crude oil, focusing on parameters such as interfacial tension (IFT), contact angle, works of cohesion (WC) and adhesion (WA), and spreading coefficient (SC). MgSO4 showed the greatest IFT reduction, MgCl2 and KCl had the shortest and longest adsorption times, respectively. Na2SO4 was able to change wettability from strongly oil-wet to strongly water-wet, while other salts could alter contact angle.

Summary: This study investigated the effect of blending crude oils on fouling propensity and found that the compatibility of crude oils significantly influences fouling. The results showed that higher fouling propensities were observed as the blends approached the threshold of incompatibility. The stability of the blends increased after fouling testing, indicating a decrease in the solubility of asphaltenes. These changes in the fluid and deposits' characteristics are associated with thermal degradation. However, further analysis is required to understand the underlying complex behavior.

Summary: In this study, the solubility of etoricoxib in supercritical CO2 was measured using a gravimetric method over a wide range of pressures and temperatures. Different solubility values were obtained depending on the applied pressure and temperature. It was found that pressure directly influenced the solubility of etoricoxib at all temperatures, while the effect of temperature depended on the crossover point in the solubility curve. Before reaching the crossover point, solubility decreased with increasing temperature, while after the crossover point, a direct relationship between solubility and temperature was observed.

Summary: This study determines the costs of using CO2 capture technologies in the refining and petrochemical sectors. Depending on the process and method used, CO2 emissions costs of EUR 30 to 40 per ton of CO2 can be avoided. Advanced low-temperature CO2 capture technologies may not provide significant benefits compared to conventional technologies. An analysis estimated a reduction potential of about 0.5-1 Gt/yr for the oil and gas industries using short- and long-term technologies. The integration of CO2 capture into the oil production process helps reduce costs and emissions.

Summary: The purpose of this research is to investigate the use of aluminananoparticles in low-salinity brine for enhanced oil recovery in carbonate oil reservoirs. Analyses including oil/water interfacial tension, zeta potential, and rock wettability were performed to select the optimized dispersions for spontaneous imbibition tests. The results showed that the addition of alumina nanoparticles in low-salinity brine can significantly reduce the oil/water interfacial tension, improve the wettability of the rock, and enhance oil production.

Summary: The surfactant EOR is considered a promising approach for enhancing oil recovery due to the changing energy supply and demand and the non-renewable nature of world oil reservoirs. However, surfactants face challenges such as high adsorption, low stability, and poor performance in harsh conditions like high temperature, high salinity, and dense carbonate rocks. There is currently no established procedure or framework for systematically selecting the best surfactant for EOR in dense carbonates.

Summary: Experiments and simulations were conducted to study the air volume fraction and hold-up in a bubble channel reactor. A new signal processing method was proposed to avoid the loss of bubble residence time. The results were in agreement with previous studies and a bubble-scale model was developed to explain the relationship between hold-up and air superficial velocity.
