Disclosed is a method of treating the wellbore area of an injection well to minimize polymer plugging around the wellbore during polymer injection. The treatment can be achieved by the injection of a dilute organic cation solution to the wellbore prior to the polymer injection and additionally having the cation present during the polymer injection. Data are shown that replacement of calcium, magnesium and sodium ions by the organic cation substantially reduce plugging.
