Literature Review Summary - IEAGHG

The surfactant solution used was 1% Alipal CD-128 in a 1% NaCl brine. Results show that sweep efficiencies were generally lower for pressures below the MMP. However, the effect of pressure on sweep efficiency for CO2-foam displacements was less than for WAG displacements and much less than for pure CO2 displacements. ................
