Numerical Validation of Asphaltene Precipitation and Deposition during CO2 miscible flooding

Petroleum Research, 2020
Asphaltene precipitation, flocculation, and deposition can significantly reduce oil production by impacting wellbores, flowlines, and more importantly, formations’ pore space around the well.

Liquid–liquid equilibrium studies of n‐butane–bitumen system with application to solvent‐aided in situ bitumen recovery

The Canadian Journal of Chemical Engineering, Volume 104, Issue 1, Page 425-441, January 2026.
Abstract Solvent‐assisted recovery methods have gained attention as an alternative to conventional thermal methods which have significant environmental drawbacks and high greenhouse gas emissions. Solvent‐assisted recovery methods can lead to various phase equilibria, such as vapour–liquid equilibrium (VLE) and liquid–liquid equilibrium (LLE), under ...

Experimental and mechanism study on the synergistic influence of asphaltene and pressure on the flow and rheological characteristics of waxy oil

Journal of Pipeline Science and Engineering
In underground reservoirs and offshore oilfields, the production and transportation of waxy oil inevitably involve pressure and asphaltene environment.

Asphaltene Stability of Some Iraqi Dead Crude oils

Journal of Engineering, 2019
Asphaltene is one of the fractions of the crude oil which is soluble in aromatics such as benzene or toluene and insoluble in alkane such as n-heptane, n-pentane or petroleum ether (mixture of alkane compounds).

Enhancing asphaltene precipitation modeling by cubic-PR solid model using thermodynamic correlations and averaging techniques

Petroleum Science, 2019
Cubic equation-of-state solid models are one of the most widely used models to predict asphaltene precipitation behavior. Thermodynamic parameters are needed to model precipitation under different pressures and temperatures and are usually obtained ...

Evaluation of rock and fluid intermolecular interaction between asphaltene and sand minerals using electrochemical, analytical spectroscopy and microscopy techniques

Scientific Reports
Long-time contact of heavy crude oil with rock leads to an adsorption phenomenon, which causes the rock surface to become oil-wet and appears as a barrier to the fluid flow in the porous media.
