Laboratory oil recovery tests using Marathon Oil Company's micellar solutions DS-9 (hydrocarbon based solvent) or FF-187 (crude based), followed by a polymer flood containing Dow Pusher, 500 ppM sodium chloride, and about 4 percent by volume isopropyl alcohol gave over 90 percent recovery of residual oil after waterflooding. Berea sandstone cores (19.8 to 23.5 percent porosity and 110 to 600 md permeability) and glass-bead packs (32.0 to 38.7 percent and 700 to 750 md) were used in the tests. The Berea cores were saturated with a 2 percent by weight sodium chloride brine, flooded with Bradford crude, and waterflooded with brine before the micellar solution flood. Distilled water was used in place of the brine for the unconsolidated packs.
