Abstract

A delayed acid breaker comprising: an inclusion compound comprising: a host molecule of cyclodextrin; and a guest molecule of an acid precursor, wherein the acid precursor hydrolyzes in water to form an acid, and wherein the acid degrades at least a portion of a filtercake located within a subterranean formation (118). A method of removing a filtercake from a subterranean formation comprising: introducing the delayed acid breaker into the subterranean formation; and allowing the acid precursor to form the acid after a desired amount of time has elapsed since the introduction of the delayed acid breaker into the subterranean formation.
