Integrated Machine Learning Model for Predicting Asphaltene Damage Risk and the Asphaltene Onset Pressure [PDF]
Asphaltene precipitation can promote a drastic reduction in oil production because of asphaltene precipitation and deposition damage. Therefore, screening models to predict the risk of asphaltene damage and equations of state (EoS) to predict the ...

Modeling of Asphaltene Precipitation and Deposition [PDF]
The tendency of Asphaltene to deposit and block tubing can potentially lead to production loss and significant cost of remediation. Unlike other deposits, the deposition behavior of Asphaltene is still not fully understood and is hindered by asphaltene ...

Investigation of Asphaltene Stability in the Iranian Crude Oils [PDF]
The influence of different factors on the asphaltene stability in three iranian crude oils was evaluated. Compositional studies and structural characterization of resins and asphaltenes were carried out in order to study a possible relationship between ...

Research Progress in Nanoparticle Inhibitors for Crude Oil Asphaltene Deposition
Currently, the alteration of external factors during crude oil extraction easily disrupts the thermodynamic equilibrium of asphaltene, resulting in the continuous flocculation and deposition of asphaltene molecules in crude oil.
