Asphaltene is a component of crude oil that has been reported to cause severe problems
during production and transportation of the oil from the reservoir. It is a solid component of …

Because of the increasing importance of heavy and unconventional crude oil as an energy
source, there is a growing need for petroleomics: the pursuit of more complete and detailed …

Asphaltene structure is one of the most controversial topics in petroleum chemistry. The
controversy is centered on the organization of aromatic cores within asphaltene molecules …

Advances in high-resolution Fourier transform ion cyclotron resonance mass spectrometry
(FT-ICR MS) enable molecular-level characterization of ultracomplex asphaltene samples …

Sulfur-containing compounds (SCCs) are the most abundant heteroatom compounds in
petroleum. The characterization of SCCs in crude oils and petroleum products has great …

Produced water is a major byproduct in oil production and the largest waste stream
generated in the petroleum industry. At the Norwegian Continental Shelf, produced water is …

Asphaltenes have traditionally been conceived as highly aromatic, alkyl-deficient
compounds enriched in pericondensed aromatic “island” motifs. This structural definition …

Numerous studies of the water-soluble fraction (WSF) from crude oil have concluded that
polycyclic aromatic hydrocarbons (PAHs) are the primary causative agents for early life …

Chemical characterization of petroleum is a challenging task due to its inherently complex
nature. For example, crude oil is believed to have as many or more compounds than the …

Asphaltenes and maltenes are defined operationally by solubility (in, eg, heptane).
Asphaltenes self-associate in solution and form putative nanoaggregates composed of …
