252 literature sources and about 5000 crude oil assays were reviewed in this work. The
review has shown that the petroleum characterization can be classified in three categories …

Previously, asphaltene science had been hindered by many significant uncertainties
regarding molecular weight, molecular structure, and nanocolloidal characteristics in …

The molecules in petroleum asphaltenes follow a molecular structure continuum similar to
the rest of the oil but differ in the formation of nanoaggregates in solution. The nature of the …

The main objective of this study was to provide novel insights into the mechanism of
asphaltene aggregation in toluene/heptane (Heptol) solutions and the effect of alkylphenols …
