摘要： Pre-coated particulate for use in a subterranean operation comprising a particulate; and a film coated onto a surface of the particulate. The film is formed by allowing an anionic polymer and a cationic surfactant to contact the surface of the particulate, and allowing the anionic polymer and the cationic surfactant to interact with each other. In some cases, the anionic polymer is selected from the group consisting of a polyacrylamide; 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.
