Asphaltene is the heaviest and most polar fraction of crude oils, which is usually defined as
a solubility class, soluble in light aromatics, benzene and toluene, and insoluble in paraffins …

The problems associated with asphaltene deposition generate significant production loss
and involve expensive corrective measures. The deposition of asphaltenes greatly reduces …

Precipitation of asphaltene is considered as an undesired process during oil production via
natural depletion and gas injection as it blocks the pore space and reduces the oil flow rate …

Heavy and extra heavy crude oils usually have a high weight percentage of asphaltene,
which could induce many problems during production to refining processes. Also …

We apply a cubic-plus-association equation of state (CPA-EOS) to study the asphaltene
precipitation in live oils from temperature, pressure, and composition effects. The live oils are …

We apply a cubic-plus-association equation of state to study the asphaltene precipitation
from n-alkane diluted model solutions (asphaltene+ toluene), and heavy oils and bitumens …

Precipitation and deposition of asphaltenes and other organic substances in formation rock
causes formation damage and reduces effective hydrocarbon mobility, which can result in …

Asphaltene deposition mostly occurs when the thermodynamic conditions, like temperature,
pressure, and oil composition of crude oil change. Therefore predicting asphaltene phase …

One of the major issues in the oil industry is asphaltene precipitation. Modeling asphaltene
precipitation is still considered as a complex problem due to various characteristics of …

Numerical modeling of asphaltene precipitation in petroleum reservoirs is important in
relation to possible precipitation around the wellbore in the producing well. Production from …
