Abstract:
Methods of introducing a treatment fluid into a subterranean formation having a filtercake deposited thereon, wherein the treatment fluid comprises a base fluid and an inclusion complex comprising a cyclodextrin compound and an acid precursor ester, and wherein the cyclodextrin compound delays hydrolysis of the acid precursor ester; contacting the treatment fluid with the filtercake; and hydrolyzing the acid precursor ester, thereby removing at least a portion of the filtercake.
