The problems associated with asphaltene deposition generate significant production loss
and involve expensive corrective measures. The deposition of asphaltenes greatly reduces …

Asphaltene precipitation and its subsequent deposition is one of the major flow assurance
problems of oil industry. This issue could arise in upstream and downstream sectors. There …

Asphaltene adsorption at solid surfaces is a ubiquitous phenomenon that begins within the
production well and continues through the entire production chain. It is generally an …

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 …

Asphaltene adsorption onto nanoparticles is an attractive subject for the heavy oil industry
for two important reasons. First, nanoparticles would remove asphaltenes from the heavy oil …

In the colloidal hypothesis of vacuum residua and asphalt, micelles are assumed to have an
asphaltenic core with the greatest weight and aromaticity and an outer shell composed of …

Asphaltenes are known to be interfacially active in many circumstances such as at toluene−
water interfaces. Furthermore, the term micelle has been used to describe the primary …

Nanoparticles (NPs) have been recently recognized as effective asphaltenes adsorbents
and deposition deterrents. The objective of this work is to provide a critical review and …

The mass loss of bitumen due to volatilization is one of the deterioration mechanisms
through which the chemical composition of bitumen deviates from its original condition …

Asphaltene and resins are heavy fractions of petroleum responsible for serious problems
during petroleum production. These problems include the formation of organic deposits in oil …
