This paper passes over the literature for residual oil characterization. The methods for
residual oil characterization are classified in: characterization based on physical and …

The aggregates of asphaltene and resin molecules play an important role in stabilizing
heavy crude oil. Although many experiments are applied to investigate the complex …

With the increased water content in heavy oil gathering pipelines and application of cold
transportation methods, understanding adhesion behavior in heavy oil/water/pipeline wall …

In response to the problem of complex interaction between oil and water in the oil–water
interface, especially heavy oil and water, this study investigated the effects of complex …

The intermolecular interaction between various components in crude oil, such as saturates,
aromatics, resins, and asphaltenes, and the zwitterionic surfactant 3 …

A series of reactive pour point depressants (PPD) with anhydride group were prepared, and
their action mechanism had been investigated by Fourier transform infrared spectroscopy …

Removing oil droplets from O/W emulsion is a difficult problem at present. In order to explore
the effect of electric field intensity on the migration and deformation of oil droplets in O/W …

Asphaltene precipitation occurs in petroleum fluids under certain unfavorable conditions, but
can be controlled by tuning composition. Aromatic solvents in large quantities can prevent …

Computer simulation studies aimed at elucidating the phase behavior of crude oils inevitably
require atomistically detailed models of representative molecules. For the lighter fractions of …

The stability of heavy crude oil is closely related to the netlike structure formed by the
aggregation of asphaltene and resin molecules inside the oil droplets, and the aggregation …
