Abstract
The present invention provides a method of generating an acid downhole that comprise providing a degradable surfactant; introducing the degradable surfactant into a well bore that penetrates a subterranean formation; and allowing at least a portion of the degradable surfactant to degrade, thereby releasing an acid. Also provided are methods of degrading an acid-soluble component present within a subterranean formation, and methods of reducing the viscosity of a viscosified treatment fluid.
