Abstract
Surfactant adsorption is one of the crucial issues in surfactant flooding to enhance the oil recovery factor. In this paper, we investigated the profound impact of two different surfactants on the carbonate rocks adsorption density in different temperatures. According to the results of this experiment, carbonate rocks adsorption density increased with the increase of surfactant concentrations. Higher surfactants’ concentration, adsorption density had reached a plateau after 7 hours. Furthermore, temperature increase has caused to reduce the adsorption density for all surfactant concentration. The maximum adsorption density is about 50 mg/g at 20 °C. Besides, polyacrylamide addition would decrease the adsorption density.
