Abstract
Treatment fluids comprising hydrofluoric acid, a hydrofluoric acid-generating compound, or any combination thereof can be used in conjunction with acidizing a subterranean formation that contains a siliceous material. Inclusion of a salt block inhibitor in the treatment fluids may eliminate or reduce the formation of insoluble fluorosilicates and aluminosilicates that can occur when an acidizing operation is conducted. Methods for treating a subterranean formation can comprise: providing a treatment fluid that comprises a salt block inhibitor comprising a fructan, and hydrofluoric acid, a hydrofluoric acid-generating compound, or any combination thereof; and introducing the treatment fluid into a subterranean formation.
