Claim:
1. A treatment fluid for reducing fines migration and comprising: a base fluid selected from the group consisting of water-based fluids, alcohol-based fluids and oil-based fluids, and coated carrier particles consisting of: carrier particles, an effective amount of a particulate additive coated on the carrier particles to reduce fines migration and to facilitate identification of a zone in a well having more than one treatment-based zone, and taggants coated on the particulate additive; wherein the carrier particles are selected from the group consisting of sand, gravel, ceramic beads, glass beads, and combinations thereof; wherein the particulate additive has a mean particle size of 1000 nm or less and is selected from the group consisting of alkaline earth metal oxides, alkaline earth metal hydroxides, transition metal oxides, transition metal hydroxides, post-transition metal oxides, post-transition metal hydroxides, piezoelectric crystals, pyroelectric crystals, and mixtures thereof; and wherein the taggant is selected from the group consisting of alkaline earth metals, transition metals, post-transition metals, lanthanoids; and mixtures thereof, where the taggant is selected to be distinguishable from the primary component.
