Abstract:
Methods, compositions, and systems that use hydrogels of graft polymers for diversion of acidic treatment fluids in subterranean formations. A method for acid diversion may comprise: applying a first acidizing treatment to a first treatment zone of a subterranean formation; introducing a hydrogel to the first treatment zone, wherein the hydrogel comprises a graft polymer that is crosslinked; and applying a second acidizing treatment to the subterranean formation, wherein the hydrogel diverts the second acidizing treatment to a second treatment zone.

Claim (Index 6):
The method of  claim 1 , wherein introducing the hydrogel to the first treatment zone comprises introducing an aqueous spacer comprising the hydrogel between the first acidizing treatment and the second acidizing treatment.
