ABSTRACT:
Methods of acidizing subterranean formations or well bores, and more specifically, to acidizing systems involving acid-generating fluids that comprise acid-generating compounds and associated methods are provided. An example of a method of the present invention comprises: providing an acid-generating fluid that comprises an acid-generating compound; placing the acid-generating fluid into a well bore penetrating a subterranean formation; and allowing the acid-generating compound to produce an acid that then acidizes at least a portion of the subterranean formation or damage contained in the formation or well bore.
