Investigation of asphaltene adsorption in sandstone core sample during CO2 injection: Experimental and modified modeling

It can be concluded that the modified model is capable of predicting the permeability reduction experimental data with AADs of 1.1-1.3%, whereas modeling based on monolayer kinetic adsorption is less accurate in the modeling of CO2 flooding processes with AADs 5.7-7.4%. Therefore, the developed model based on multilayer adsorption theory is more accurate than models based on monolayer adsorption theory and is in good agreement with the experimental data reported in this work.
