Adsorption of surfactants from aqueous solutions in porous media is fundamental in enhanced oil recovery (EOR) because surfactant loss reduces the effectiveness of the chemical solution injected, making the process economically unfeasible. This paper

Large investments in exploratory activities have stimulated new oil discoveries, generally in carbonate reservoirs. These reservoirs tend to be oil-wet, an aspect that impairs the mobilization of oil in the reservoir. However, different methods can b
