文摘

Biosurfactant ethoxylated phytosterols are used in chemical EOR for the first time. Cosurfactant alcohols show the synergistic effects with the BPS-30 in IFT reduction. There is a close relationship between the IFT reduction and the alcohol chain length. Ultra-low IFT can be achieved with the assisted of cosurfactant n-pentanol.
