摘要：Pre-coated particulate for use in a subterranean operation comprising aparticulate; and a film coated onto a surface of the particulate. The film is formed byallowing an anionic polymer and a cationic surfactant to contact the surface of theparticulate, and allowing the anionic polymer and the cationic surfactant to interact witheach other. In some cases, the anionic polymer is selected from the group consisting of apolyacrylamide; an alkylpolyacrylamide; a copolymer of polyacrylamide, with ethylene,propylene, and styrene; a copolymer of alkylpolyacrylamide with ethylene, propylene,and styrene; a polymaleic anhydride; and any derivatives thereof.
