Abstract:
The rapid reaction of hydrofluoric acid with siliceous materials can make it difficult to achieve localized dissolution of siliceous minerals during subterranean stimulation operations. Methods for stimulating a subterranean formation in the presence of a particulate pack can comprise: providing a latent hydrofluoric acid composition comprising a degradable matrix, and a hydrofluoric acid precursor dispersed in the degradable matrix; setting a particulate pack in a wellbore or in a subterranean formation comprising a siliceous material that is penetrated by the wellbore, the particulate pack comprising particulates and a solid form of the latent hydrofluoric acid composition; degrading at least a portion of the degradable matrix, thereby exposing at least a portion of the hydrofluoric acid precursor; converting the exposed hydrofluoric acid precursor into hydrofluoric acid; and reacting the hydrofluoric acid with the siliceous material adjacent to a location in the particulate pack where the latent hydrofluoric acid composition was present.

Claim (Index 18):
The method of  claim 11 , wherein the first treatment fluid is introduced into the wellbore at or above a fracture gradient pressure of the siliceous material.
