X-ray Photoelectron Spectroscopy Analysis of Hydrotreated Athabasca Asphaltenes
, 2017C7 asphaltenes from Athabasca crude oil were hydrotreated using a commercial NiW/Al2O3 catalyst and analyzed using X-ray photoelectron spectroscopy. Results showed that the catalyst performed better in the removal of sulfur rather than nitrogen and that ...

Nanoparticles for Inhibition of Asphaltenes Deposition during CO2 Flooding
, 2016The deposition of asphaltenes in porous media is one of the most difficult problems during CO2 flooding. In this paper, the adsorption of asphaltenes onto Al2O3 nanoparticles was studied through two methods: (i) by adding a certain mass of nanoparticles ...

Reservoir impairment by asphaltenes: A critical review
, 2016Precipitation and deposition of asphaltenes and other organic substances in formation rock causes formation damage and reduces effective hydrocarbon mobility, which can result in significant production losses.

Asphaltene constituents are best known for the problems they cause as solid deposits that obstruct flow in the petroleum production systems and refining as well as the formation of coke during processing. Asphaltene separation (phase-separation) can also be a cause of asphalt instability.
