ABSTRACT:
A method to invert an inverse emulsion water compatible polymer product using a combination of surfactants that have specific chemical structures is disclosed. A combination, or blend, of two or more surfactants provides for an effective breaker system. The blend of surfactants is more effective than the individual surfactants.
