A new screening technique was developed in which optimum values of parameters such as ultimate liquid recovery, recovery at breakthrough, cumulative liquid produced to cumulative air produced ratio, liquid injection pressure ratio, and breakthrough time during the porous media tests were used to select the surfactants that are most likely to help diversion. Seven surfactants were analyzed and four were selected for further evaluation under high-pressure diversion conditions using four different permeability contrast values. To further validate the proposed screening criterion, foam diversion results were obtained in the presence of residual oil.
