Bitumen, a product mostly used as a binder in road construction, has been subject of
numerous scientific investigations with the goal to optimise its function as an engineering …

Asphaltene is the heaviest and most polar fraction of crude oils, which is usually defined as
a solubility class, soluble in light aromatics, benzene and toluene, and insoluble in paraffins …

For decades, discussion of asphaltene structure focused primarily on molecular weight. Now
that it is widely accepted that asphaltene monomers are between∼ 250 and 1200 g/mol …

Molecular modeling is applied to a representative array of kerogens for the purpose of
obtaining quantitative predictions of thermodynamic properties from quantum mechanics …

New chemical compositions of model asphalts to represent the AAA-1, AAK-1 and AAM-1
asphalts of the Strategic Highway Research Program are proposed to enable molecular …

Despite kerogen's importance as the organic backbone for hydrocarbon production from
source rocks such as gas shale, the interplay between kerogen's chemistry, morphology and …

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 …

Asphalt materials are uneven and complex organic matter, and the properties of asphalt–
aggregate interfaces are also complex. This makes it difficult for researchers to understand …

Asphaltene deposition in the reservoirs, tubbing, and surface facilities causes serious flow
assurance problems with significant economic implications. Asphaltene flow assurance …

In petroleum science, asphaltenes are well-known as the most refractory fraction of crude oil
and remain infamous for problems in production, transportation, and refining processes …
