Abstract
A method of controlling a permeability zone in a reservoir includes introducing a diverter agent comprising a morpholinium based zwitterionic surfactant including a sulfonate terminal moiety, an ammonium-based zwitterionic surfactant, and an activator in a wellbore. Once introduced, the diverter agent contacts a high permeability zone in the reservoir. The diverter agent heats and gels to form a gelled diverter agent in the high permeability zone, subsequently forming a zone of decreased permeability.
