Static Adsorption of dodecyl alkyl sulfate onto kaolinite: An experimental investigation for enhanced oil recovery purpose

초록

The injection of surfactants into depleted reservoirs to enhance oil production is a well-known EOR method. Surfactant flooding has issues with porous media in reservoirs, such as adsorption, which diminish the efficiency of the chemical slurry. Static experiments were performed to investigate the adsorption of dodecyl alkyl sulfate in kaolinite by determining the critical micelle concentration (CMC) and by investigating its behavior with adsorption isotherms models.
