OIL RECOVERY USING POLYMER PRESLUG
Oil recovery from reservoirs having connate water containing at least 500 ppm of divalent cation is improved by first injecting an aqueous preslug containing 50 - 2,000 ppm of a biopolymer and thereafter injecting a displacement slug, preferably a micellar dispersion, followed by a mobility buffer f...

| description | Oil recovery from reservoirs having connate water containing at least 500 ppm of divalent cation is improved by first injecting an aqueous preslug containing 50 - 2,000 ppm of a biopolymer and thereafter injecting a displacement slug, preferably a micellar dispersion, followed by a mobility buffer fluid and this, in turn, followed by a water drive. The preslug containing the biopolymer "insulates" the micellar dispersion from the connate water, the divalent cation tends to degrade the micellar dispersion. |
