The present invention provides a method of treating a subterranean formation with a particulate laden fluid whereby particulate flowback is reduced or prevented. The method includes the steps of providing a fluid suspension including a mixture of a particulate, a tackifying compound and a hardenable resin, pumping the suspension into a subterranean formation and depositing the mixture within the formation whereby the tackifying compound retards movement of at least a portion of the particulate within the formation upon flow of fluids from the subterranean formation and said hardenable resin subsequently consolidates at least a portion of said particulate within said formation.
La présente invention a pour objet une méthode pour le traitement d'une formation souterraine à l'aide d'un fluide chargé de particules dont l'utilisation réduit ou élimine le reflux des particules. La méthode comporte les étape suivantes : élaboration d'une suspension incorporant un mélange de particules, un agent collant et une résine durcissable, suivie du pompage de la suspension vers la formation souterraine et du dépôt du mélange à l'intérieur de la formation; l'agent collant ralentit le mouvement d'une partie des particules en dépit de la circulation fluidique à l'intérieur de la formation jusqu'à la solidification des particules par durcissement de la résine.
