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 …

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 …

One of the main approaches for compositional analysis of crude oils is SARA fractionation in
which the sample is separated into saturate, aromatic, resin, and asphaltene fractions based …

A number of indices generated from SARA analyses data are used for characterization of
petroleum mixtures (eg colloidal instability index I c=(As+ S)/(R+ A) and asphaltene index I …

Asphaltene is one of the component of asphalt binder. Asphaltene certainly contributes to
the elasticity and stiffness of a binder's traditional viscoelastic behaviour. Introducing …

Carbon dioxide (CO 2) injection is one of the most applied enhanced oil recovery methods
in the hydrocarbon industry, since it has the potential to increase oil recovery significantly …

Twenty-two straight run vacuum residues extracted from extra light, light, medium, heavy,
and extra heavy crude oils and nine different hydrocracked vacuum residues were …

The petroleum refining industry employs a wide variety of heat transfer‐based equipment
which tend to foul due to the complex nature of associated fluid streams and process …

Crude oils are usually associated with many compounds, some of which are favorable and
others, which are not. One of the most unfavorable components of crude oil that pose severe …

Abstract Poly (ethylene glycol)/chitosan (PEG/CH) hydrogel and its composite containing
carbon nanotubes (PEG/CH/CNTs) were prepared using a simple blending method. The …
