Modeling Asphaltene Precipitation-Part II: Comparative Study for Asphaltene Precipitation Curve Prediction Methods

Journal of Engineering
Asphaltenes' solubility in crude oils is frequently affected by temperature, pressure, and oil composition changes. This could lead to the precipitation and deposition of asphaltene in various parts of the total production system, which would cause a ...

Insights into asphaltene stability, aggregation, deposition and molecular structure [PDF]

, 2019
Asphaltenes are the heaviest, most polar, and most surface-active species of crude oils which are fairly stable in the oil; however, a small variation in the pressure, composition, and temperature can cause asphaltene phase instability and alteration in ...
