Beschreibung
Zusammenfassung:	A method comprises providing a treatment fluid comprising a gelling agent, an aqueous base fluid, a buffer composition comprising a plurality of salts, and a crosslinking agent; and contacting a subterranean formation with the treatment fluid. The method may be used in subterranean formation having a temperature greater than about 200° F., and the treatment fluid useful with the method may have a high shear recovery greater than 100%.
