摘要：
A method is for treating a subterranean formation penetrated by a wellbore is given which comprises providing a treatment fluid comprising a viscoelastic surfactant having at least one degradable linkage, a hydrolysable material, and a pH control material, wherein the pH control material has a pH equal or greater than about 9 and comprises a strongly alkaline material and an oxidizing agent; and injecting into the subterranean formation the treatment fluid.
