Patent ID: 7721803

Claim:
A method for reducing fines migration within a particle pack in a subterranean formation comprising introducing into the subterranean formation a fluid comprising: a base fluid selected from the group consisting of water-based fluids, alcohol-based fluids and oil-based fluids; particles selected from the group consisting of sand, gravel, ceramic beads, glass beads and combinations thereof; a coating agent comprising oil, where if the base fluid is oil-based, the oil is the same as or different from the oil-based fluid; and an amount of a particulate additive effective to reduce fines migration, the particulate additive having a mean particle size of 100 nm or less, being 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 coated on the particles with the coating agent.
