A new type of green low surface energy surfactant (LSES) that is stable in the harsh conditions of enhanced oil recovery (EOR) has been reported. This efficient surfactant examined by scientists at Swansea University is shown to improve the oil recovery by 72% in both low and high brine solutions, a remarkable result for only a single chain surfactant flooding, compared to 45% recovery in the presence of other surfactants alone.
