在美国路易斯安那州WhiteCastle（W．C．）油田的一个油藏中进行了一次无聚合物流度控制的注助表面活性剂－强化碱的三次采油工艺试验。尽管注入液是不稳定的，但作为真正的三次采油工艺，它至少采出了油层注水后残余油的38％。并表明它的驱替效率为100％。碱与助表面活性剂在油层中的损耗是可以接受的，而且也可预测。
An oil-free surfactant-enhanced alkali recovery test was conducted in a reservoir in the WhiteCastle (W.C.) oil field in Louisiana, USA. Although the injection fluid is unstable, it has at least 38% of the residual oil remaining after water injection as a true tertiary recovery process. And showed that its displacement efficiency is 100%. The loss of alkali and cosurfactants in the reservoir is acceptable and predictable.
