Patent ID: 7703531

Claim:
A method for reducing fines migration in a subterranean formation comprising: introducing into the subterranean formation a fluid comprising: an aqueous base fluid; a viscoelastic surfactant in an amount effective to increase the viscosity of the fluid; proppants; an amount of a particulate additive effective to reduce fines migration and further in an amount effective to have an effect selected from the group consisting of improved viscosity stability, improved fluid loss, and both, as compared with an otherwise identical fluid absent the additive, where the particulate additive: has a mean particle size of 100 nm or less, is selected from the group consisting of alkaline earth metal oxides, alkaline earth metal hydroxides, alkali metal oxides, alkali metal hydroxides, transition metal oxides, transition metal hydroxides, post-transition metal oxides, post-transition metal hydroxides, piezoelectric crystals, pyroelectric crystals, and mixtures thereof; and pumping the fluid against the subterranean formation with sufficient pressure to cause at least one fracture; and depositing the proppants and the particulate additive into the at least one fracture to form a proppant pack.
