Summary: The main goal of Petroleum Exploration and Production (E&P) companies is to achieve sustainable hydrocarbon production throughout the oil field life, but asphaltene precipitation and deposition pose a major challenge to this goal. Proper screening of asphaltene stability in crude oils can help predict stability accurately and plan preventive measures. Different dead and live oil screening techniques have their own limitations, risks, and advantages, and a detailed analysis and comparison can help in selecting the best technique for monitoring asphaltene stability in crude oils.

Summary: Understanding the mechanisms of viscosity enhancement in crude oil phases is crucial for optimizing extraction and transportation processes. This study employed molecular dynamics simulations to investigate the behavior and viscosification mechanism of asphaltene molecules in complex oil phases. The research suggests that electrostatic interactions and interactions between asphaltene and crude oil molecules contribute to the enhanced viscosity. The findings provide insight into the viscosity enhancement mechanisms in crude oil phases.

Summary: Despite significant efforts to understand the reaction mechanism of asphaltenes during aquathermolysis reaction, knowledge about their molecular structures and reaction pathways remains limited. This work extensively reviews and discusses experimental results from different samples of asphaltenes during aquathermolysis reaction to obtain information on their elemental composition, functional groups, and average structural parameters. The findings provide theoretical support for future research on the aquathermolysis of heavy crude oils with various catalysts and highlight the impact of operating conditions, catalyst type, and asphaltene structure on the changes in asphaltenes.

Summary: An advanced method for fabricating highly effective ZnCo2O4-ZnO nanocatalyst using Polyethylene glycol (PEG) as a fuel and stabilizer was successfully developed. The dimensions, performance, and shape of ZnCo2O4-ZnO nanoparticles were effectively controlled by changing the type and quantity of PEG. Characterization of the produced ZnCo2O4-ZnO nanostructures was conducted using FTIR, XRD, TGA, SEM, and TEM. The ZnCo2O4-ZnO nanostructures showed excellent adsorption and elimination properties for asphaltene in crude oil, and the catalyst could be reused multiple times without significant loss in activity and selectivity.

Summary: The aim of this study is to examine the implications of high oil dependency on political stability in both oil-exporting and oil-importing countries. Using network analysis, we identify the most connected countries in global crude oil trade and their role in intermediating the flows. Our findings support the resource curse hypothesis for oil-exporting countries, connecting it to the emergence of rent-seeking behaviors. Interestingly, we also find a different type of resource curse hypothesis that affects intermediary countries. Furthermore, heavily oil-dependent countries that import oil as their main energy source are highly exposed to geopolitical turmoil and the risk of importing political instability together with oil.

Summary: Efficient demulsifiers with varying viscosities were evaluated for their demulsification potential on asphaltene stabilized crude oil emulsions. The demulsifiers showed better performance at ambient conditions in demulsifying emulsions formed from distilled water, while the higher viscosity demulsifier achieved a lower water removal. Seawater hastened demulsification. In the presence of salts, the demulsifiers demonstrated excellent demulsification and the performance varied depending on the type of salt. Injection of demulsifiers reduced the viscosity and shear stress of the emulsion, with the highest reduction observed in the lower viscosity demulsifier. A demulsification mechanism was proposed based on the analysis of optical microscopic images.

Summary: In this study, ultrafiltration membranes were developed for the removal of asphaltenes from crude oil using a nonsolvent-induced phase separation method. The addition of acrylic acid in acrylonitrile copolymers improved the fouling resistance of the membranes, resulting in a reduction in both total fouling and irreversible fouling. The membranes demonstrated high toluene permeance and effective rejection of asphaltenes, indicating their promising potential for efficient removal of asphaltenes from crude oil.

Summary: Graphene derivatives have been used as additives to enhance the properties of bitumen. However, previous research found that the poor compatibility between graphene derivatives and asphaltene aggregates in bitumen leads to negative effects. In this study, a surface chemistry modification of graphene was conducted to achieve phase compatibility with asphaltene aggregates. The functionalized graphene was stable in bitumen and successfully improved its material properties.

Summary: Some crude oils contain natural surfactants that prevent hydrate agglomeration, which is linked to the aggregation state of asphaltenes. Artificially modifying the aggregation state of asphaltenes can alter the natural hydrate antiagglomeration properties of crude oils. This finding could have implications for novel hydrate management strategies that utilize the intrinsic antiagglomerant properties of certain crude oils.

Summary: In this work, the phase behavior of a live presalt crude oil with high CO2 content was investigated using a combination of measurement and modeling techniques. The phase transitions were measured and modeled in the form of a (p, T) diagram, with additional measurements carried out in a pseudobinary oil + gas model system.

Summary: In this study, a series of multi-alkylated aromatic amides (MAA) amphiphiles were synthesized and evaluated as asphaltene dispersants for Saudi crude oil. Experimental results showed that adding MAA-3 significantly increased the initial flocculation point, reduced the size of asphaltene aggregates, and increased the viscosity of the oil sample. The number of alkyl side chains was found to affect the performance of the asphaltene dispersants, with MAA-3 exhibiting the best performance. Molecular simulation results further validated the experimental findings.

Summary: This study established a nanoindentation method to measure the turgor pressure and envelope elasticity of live bacteria, and found that the Young's modulus of bacterial envelope is sensitive to the external osmotic environment, and turgor pressure is significantly dependent on the external osmotic stress. This method can not only quantify these mechanical properties of bacteria, but also help understand their behaviors in different environments.
