The crude oil recovery process is frequently associated with the formation of stable
emulsions due to factors such as turbulent flow in pipelines and the presence of surface …

Asphaltenes, complex aromatic compounds from various carbonaceous sources, could be
obtained by solvent dissolution, filtration and adsorption. It was difficult to clarify the …

This study investigates the effects of asphaltene, resin and petroleum acid on the phase
inversion, stability and oil–water interface characteristics of emulsions. First, different ratios …

To further develop the microscopic structure of asphalt, the new asphalt molecular model
including 50 types of molecules was proposed. The dipole moment, molecular electrostatic …

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

One major challenge often encountered during the production and transportation of crude oil
in petroleum industries is the formation of extremely stable emulsions. This problem is …

Gas hydrates constitute a major flow assurance issue in the transportation of oil and gas
from the reservoir to the point of sale via pipelines. They can reduce or arrest the …

After years of research into the heavy components of crude oil, asphaltenes are still one of
the most complex and unknown organic molecules. During these years, asphaltene has …

Resin accounts for over 30% of the composition of Liaohe heavy crude oil and can result in
severe difficulties in oil recovery and transportation. To determine the structure of the resin …

Air injection is a promising method to enhance light crude oil recovery. To effectively utilize
this technology, understanding the oxidation behaviour and interactions of SARA …
