Asphaltenes, the most aromatic of the heaviest components of crude oil, are critical to all
aspects of petroleum utilization, including reservoir characterization, production …

We review the existing literature on asphaltenes at various types of interfaces: oil–water, air–
water, gas–oil and solid–liquid, with more emphasis on the oil–water interfaces. We address …

The Yen–Mullins model, also known as the modified Yen model, specifies the predominant
molecular and colloidal structure of asphaltenes in crude oils and laboratory solvents and …

Asphaltenes, the most aromatic of the heaviest components of crude oil, are critical to all
aspects of petroleum use, including production, transportation, refining, upgrading, and …

Emulsions of oil droplets in water but more typically water droplets in oil are common in the
production, transportation, and refining of petroleum and related products. Emulsions of …

The components of petroleum asphaltenes exhibit complex bridged structures comprising
sulfur, nitrogen, aromatic, and naphthenic groups linked by alkyl chains. These components …

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 …

Asphalthenes are typically defined as the fraction of petroleum insoluble in n-alkanes
(typically heptane, but also hexane or pentane) but soluble in toluene. This fraction causes …

Complementary neutron and X-ray small angle scattering results give prominent information
on the asphaltene nanostructure. Precise SANS and SAXS measurements on a large q …

After a nearly decade absence, we present a review of noteworthy contributions in
petroleum analysis over the past 3 years, intentionally limited to∼ 250 references. The …
