The increasing demand for fossil fuels and the depleting of light crude oil in the next years
generates the need to exploit heavy and unconventional crude oils. To face this challenge …

Asphaltene precipitation/deposition is considered a problem of formation damage, which
can reduce the oil recovery factor. In addition, asphaltenes can be deposited in pipelines …

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

The solubility of oxygen in 21 pure organic solvents was measured at 298.2 K and 101.33
kPa using the static method. The Hansen solubility parameters (HSPs) of oxygen were …

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 …

In the present work, we investigate, by means of theoretical simulation, the preferred
orientation of a model asphaltene molecule at the oil–water interface (monomer). The …

The main objective of this study is to investigate the effect of resin I on the adsorption
behavior of n-C7 asphaltenes onto silica and hematite nanoparticles. It is worthwhile to …

Asphaltene nanoaggregates from three diverse source materials coal-derived asphaltenes
dominated by aromatic carbon, petroleum asphaltenes with comparable abundances of …

The Hansen solubility parameters (HSPs) of asphaltenes extracted from oil sand bitumen
samples produced at Athabasca in Canada and also from a vacuum residue fraction (VR) …

Unconventional rock or sediment units require stimulation to produce retained petroleum
due to the combined effects of petroleum viscosity and matrix permeability. Despite intense …
