A tertiary recovery process is described for improving the recovery of oil from a reservoir which has been waterflooded. The process consists of injecting a material which is somewhat soluble in water and more soluble in the reservoir oil, injecting a second material which is miscible with the first injected material, and injecting a third material which is miscible with the second injected material.
