Heavy oil, commonly defined by high density, viscosity, and heavy components
distinguishing it from light oil, has a peculiar nature with respect to emulsification. In this …

The depletion of conventional resources and steady increase in the global oil demands has
led to the shift of attention to the unconventional resources which are difficult to extract due …

Asphaltenes comprise the heaviest and least understood fraction of crude petroleum. The
asphaltenes are a diverse and complex mixture of organic and organometallic molecules in …

Heavy oil and bitumen supply the vast majority of energy resources in Canada. Different
methods can be implemented to produce oil from such unconventional resources …

In recent years, the dominant organizing role of non-covalent π-stacking interactions in the
association of asphaltenes and porphyrins was criticized and replaced with cooperative …

The increase in global energy demand and decrease in easily extractable light crude oil has
generated a growing interest in heavy oil exploitation. However, the high viscosity of heavy …

To understand the millisecond pyrolysis behavior of heavy oil over solid base catalyst from
the near-molecular level and the relationship between the structural composition and the …

Asphaltene and asphalte precipitations during production, transportation and processing of
crude oil are one of the problems in the oil industry. The amount and characteristics of these …

Surface microstructures of bitumen are key sites in atmospheric photo-oxidation leading to
changes in the mechanical properties and finally resulting in cracking and rutting of the …

Aggregation of asphaltenes remains a scientific challenge. In the present contribution, at
first, transverse magnetization relaxation (T2) data from low-field NMR measurements of the …
