The present invention relates to aqueous tackifiers and methods of controlling particulates in subterranean formation using aqueous tackifiers. Some embodiments of the present invention provide methods of controlling particulates, comprising placing an aqueous tackifier compound into a portion of a subterranean formation comprising unconsolidated particulates; and, activating the aqueous tackifier compound. Other embodiments of the present invention provide methods of coating a portion of a surface in a subterranean formation comprising substantially coating an aqueous tackifier compound onto a portion of a subterranean formation; and, activating the aqueous tackifier compound. Other embodiments of the present invention provide treatment fluids for controlling fine particulates, comprising a servicing fluid and an aqueous tackifier compound.

L'invention concerne des agents poisseux aqueux et des procédés de commande de matières particulaires dans une formation souterraine au moyen d'agents poisseux aqueux. Dans certains modes de réalisation, l'invention propose des procédés de commande de matières particulaires qui consistent : à placer un composé d'agent poisseux aqueux dans une partie d'une formation souterraine comprenant des matières particulaires non consolidées ; et à activer le composé d'agent poisseux aqueux. D'autres modes de réalisation de l'invention propose des procédés de revêtement d'une partie d'une surface dans une formation souterraine qui consistent : à revêtir sensiblement un composé d'agent poisseux aqueux sur une partie d'une formation souterraine ; et à activer le composé d'agent poisseux aqueux. D'autres modes de réalisation de l'invention concernent des fluides de traitement permettant de commander des matières particulaires fines, qui comprennent un fluide d'entretien et un composé d'agent poisseux aqueux.
