Summary:Disclosed is a process for on- and off-site tagging of fracking sand and a composition of matter capable of being utilized in that process. The composition of matter includes a linker polymer conjugated to a rare earth particle. The method involves forming two mixtures, a first involving mixing a linker polymer conjugated to a rare earth particle into an aqueous blend of fracking sand, and a second involving an activated amine terminated polymer in an aqueous solution. The second mixture is then added to the first mixture, and covalent amide bonds are formed. La présente invention concerne un procédé de marquage sur site et hors site de sable de fracturation et une composition de matière susceptible d'être utilisée dans ledit procédé. La composition de la matière comprend un polymère de liaison conjugué à une particule de terres rares. Le procédé consiste à former deux mélanges, un premier mélange comportant le mélange d'un polymère de liaison conjugué à une particule de terres rares dans un mélange aqueux de sable de fracturation, et un second mélange comportant un polymère activé terminé par un groupe amine dans une solution aqueuse. Le second mélange est ensuite ajouté au premier mélange, et des liaisons covalentes d'amide sont formées.
