ABSTRACT:
Gelled acidic compositions suitable for either matrix-acidizing or fracture-acidizing of subterranean formations, and methods of using said compositions in acidizing operations, are provided. Said compositions comprise water, a water-dispersible polymer of acrylamide, an acid, and an aldehyde capable of causing gelation of an aqueous dispersion of said polymer, said acid, and said aldehyde. Preferably a mixture of aldehydes is used. However, either a mixture of aldehydes or a single aldehyde can be used with certain polymers, and in certain methods comprising particular combinations of steps.
