... by co-injection of nitrogen gas and surfactant solution in a glass bead pack. The foam continuously washes the upper end-face of a vertical core sample. This geometry simulates a foam flowing in a fracture. The resulting flows generated in the matrix and the low-IFT values gives a total oil recovery...

.... Adsorption losses of surfactants on core sample showed that the dynamic adsorption losses of surfactant AS-13 and SPS1708 were 0.46mg/g and 0.37mg/g respectively. Core flooding tests of chemical flooding proved that more than 17~18% incremental oil recovery over water flooding could be obtained with ASP...
