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 …

Asphaltenes are the heaviest components in crude oil. It is generally believed that
asphaltenes adsorbed at oil/water interface can form a protective layer to stabilize the water …

The potential of physical methods for in situ studies of the phase stability and
physicochemical evolution of heavy oils is analyzed. The basic principles of in situ …

Despite the existing literature, the mechanisms of asphaltenes aggregation, precipitation,
and adsorption/deposition in relation to the structural motifs of asphaltenes remains unclear …

Solvent bitumen extraction processes are alternatives to thermal processes with potential for
improved economic and environmental performance. However, solvent interaction with …

This paper presents results of our study of the kinetics of asphaltene aggregation as a
function of different precipitants, solvents, and the Hildebrand solubility parameter δ. The …

Asphaltene precipitation and deposition is a serious issue in all facets of petroleum
production and processing. Despite the numerous experimental efforts concerning …

Hypothesis Surface interactions of bubbles and oil with interface-active species like
asphaltenes influence many interfacial phenomena in various engineering processes. It …

CO 2 enhanced oil recovery has a great potential to improve the rate of oil production and
store carbon dioxide emission. However, CO 2 injection can destabilize the asphaltene-oil …

The study of the asphaltene deposition mechanism is critical to understand and solve
important problems in the petroleum industry. The same is valid for the selection of inhibitors …
