Binary and ternary surfactant blends for enhanced oil recovery in reservoir brines with extremely high total dissolved solids


A binary or ternary surfactant mixture for use in enhanced oil recovery within a reservoir having total dissolved solids greater than approximately 80,000 parts per million (i.e., heavy to extreme brine conditions) includes at least two of a propoxylated/ethoxylated alcohol sulfate, an ethoxylated alcohol sulfate, and a monoalkyl or dialkyl diphenyloxide disulfonate. The surfactant mixture is used without alcohol, which is unnecessary to maintain solution stability and good coalescence rates and thus improves compatibility with polymers added to improve the mobility ratio.
