Beschreibung
Zusammenfassung:	The invention relates to in-situ acidizing processes that involve the dissolution of an acid-soluble material. Treatment fluids have been identified that can effectively dissolve acid-soluble materials at low temperatures, such as temperatures of 30° C. or lower. In some embodiments, the processes may also be usefully employed at higher temperatures. The processes and treatment fluids of the invention can advantageously be used to dissolve acid-soluble materials, including filter cakes, in underground formations.
