surfactant flooding
3.Study on the Feasibility of OCS Oil - displacement Surfactant Used for Surfactant Flooding in Different Block - faulted Oilfield
4.FIELD TESTS OF ENHANCING RECOVERY BY SURFACTANT FLOODING IN THE ZHOUCHENG OIL FIELD
5.The alkali/surfactant/polymer(ASP) flooding is generally considered as a new technology that not only increase sweep efficiency but also improve displacement efficiency, and that it is regarded as a very important technology in EOR process and have awarded tremendous success both in pilot test and industrialized application stages.
6.The multivariate foam is generated by natural gas and an ASP flooding solution, which is composed of 1.2×10 4 mg/L NaOH, 3×10 3 mg/L surfactant ORS41, and 1.2×10 3 mg/L HPAM 1275A in water of TSD=3 700 mg/L.
