The role of CO2 and ion type in the dynamic interfacial tension of acidic crude oil/carbonated brine

Abstract The effects of CO2 and salt type on the interfacial tension (IFT) between crude oil and carbonated brine (CB) have not been fully understood. This study focuses on measuring the dynamic IFT between acidic crude oil with a total acid number of 1.5 mg KOH/g and fully CO2-saturated aqueous sol...
