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 ...

Asphaltene Aggregation and Deposition in Porous Micromodel

, 2015
Asphaltene deposition is a common cause of flow assurance problems in wellbores and production equipment as well as near-wellbore regions in oil reservoirs. Therefore, understanding the mechanism by which asphaltenes deposit onto solid surfaces is highly
