Aspects of the invention relate to compositions and methods that are used for the remediation of near-wellbore damage in regions of formations near injection wells in communication with subterranean reservoirs. The damage is caused by previous injection of a polymer emulsion into the injection well. A specific aspect is a method of injecting into the subterranean reservoir a composition containing an olefin sulfonate, a sulfosuccinate, and a chemical selected from an alcohol alkoxylated sulfate, an alcohol alkoxylated carboxylate, or a combination thereof. The polymer emulsion is thereby dissolved, cleaned and/or flushed away from the region near the injection well.
