Summary: A novel functional magnetic nano-demulsifier with efficient oil-water separation and recyclability was prepared by one-pot method. The magnetic fluorinated polyether composite demulsifier (Fe3O4@C-F) was successfully compounded on Fe3O4, improving the crystallinity of the composites. The demulsification experiment showed that Fe3O4@C-F had the best demulsification effect at a dosage of 600 ppm, 65°C, 120 min, and pH value of 6.

Summary: In this study, carboxymethyl cellulose (Walocel) and methyl cellulose-E5 were found to be more effective for deionized water-in-crude oil demulsification. The presence of ions slowed down the demulsification of Methocel-E5 more than that of Walocel, likely due to the different hydrogen bond strength and van der Waals interactions with water molecules. The polar 2-hydroxypropyl substitutes in Methocel E5 resulted in much less effective saline demulsification compared to Walocel.

Summary: To address the demulsification issue of oil-water emulsion, a highly efficient and recyclable magnetic fluorine-containing polyether composite demulsifier (Fe3O4@Ti-F) was synthesized. Fe3O4@Ti-F was prepared by combining magnetic nanomaterial TiO2 with Fe3O4 and grafting fluorinated polyether using a one-pot method. The successful synthesis of Fe3O4@Ti-F was confirmed using SEM, FTIR, TEM, and XPS. The demulsification performance of Fe3O4@Ti-F was evaluated using a self-made crude oil emulsion, and the demulsification mechanism and the effect of external factors such as temperature and pH were discussed. The results showed that Fe3O4@Ti-F achieved a demulsification efficiency of 90.83% for a 50:50 (v/v %) W/O emulsion at a dosage of 600 mg/L, a temperature of 65 degrees C, and a time of 30 min. Fe3O4@Ti-F exhibited good magnetic properties and could be recovered and recycled from the two-phase system for up to 4 times with a demulsification efficiency of over 60%. Fe3O4@Ti-F has great potential in energy-saving oil-water separation.

Summary: A series of amphiphilic copolymers (PIDs) were synthesized by copolymerization of isobutyl acrylate (IBA) and N,N-dimethylacrylamide (DMAA). The structure, composition, and molecular weights of these copolymers were characterized. The solubility and aggregation behavior of these copolymers in different solvents were studied. The demulsification experiment showed that PID demulsifiers had excellent efficiency for super heavy oil emulsions. The morphology and activity changes during demulsification proved the role of lipophilic segments in accelerating water droplet condensation.

Summary: Interfacial tension (IFT) between crude oil and water is a critical property that affects multiphase flow in porous media. Measuring IFT in the laboratory is challenging, and tools for downhole measurement are currently unavailable. Existing reservoir simulators rely on empirical models that do not accurately account for crude oil chemistry. This study developed a potential model for downhole IFT measurement using crude oil samples from different fields. The model can improve saturation height function modeling, aid in field development planning and production strategies, and serve as a monitoring tool to prevent technical issues.

Summary: A new type of ionic liquid demulsifier, HDEA-TFA, with both hydrophilic and hydrophobic chains, was synthesized and identified with its chemical structure. It showed excellent demulsifying ability for two water-in-crude oil (W/O) emulsions with different ratios. The influences of demulsification conditions on the demulsifying efficiency (DE) were discussed, and the results indicated that HDEA-TFA could achieve 100% DE within 120 minutes at a concentration of 500 mg/L and a temperature of 60℃. Moreover, HDEA-TFA exhibited remarkable resistance to acidity, alkalinity, and salinity. The demulsifying mechanism was investigated through various measurements, and this study provided a reference for further research on demulsification mechanisms.

Summary: This study focuses on the poor demulsification performance of light crude oil emulsions in low-permeability oilfields at low temperatures. The composition of the emulsion samples, clay particle size distribution, and the viscosity-temperature relationship curve of the samples were analyzed. The demulsification effect of different commercial types of demulsifiers was examined using the bottle test method, revealing the demulsification mechanism. Field tests confirm the demulsification capabilities of PR demulsifiers, which combine features of decreasing interfacial tension and adsorbing SiO2 for quick demulsification and flocculation at low temperatures. This research provides a theoretical and practical foundation for the study and advancement of low-temperature demulsification technology in oilfields.

Summary: The study showed that the combination system of amphiphilic polymer and surfactant exhibited better emulsifying ability and emulsion stability compared to using either component alone. The improvement was attributed to the low interfacial tension generated by the addition of surfactant, as well as higher external viscosity and stronger interfacial film strength in the emulsion formed by the combination system. These factors collectively slowed down emulsion droplet migration velocity and prevented droplet coalescence, ultimately increasing emulsion stability.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
