Polymer-Surfactant Interaction and its Effect on the Mobilization of Capillary-Trapped Oil
Surfactant slug/polymer drive systems which have proved to be effective in recovering waterdrive residual oil in 30 cm long Bentheim sandstone cores have been found to be much less effective in longer (90 cm) cores. This is attributed to polymer/surfactant phase separation, the phenomenon which has little time to develop in experiments with short cores.
