Title
(EN) DEGRADABLE FLUID SEALING COMPOSITIONS HAVING AN ADJUSTABLE DEGRADATION RATE AND METHODS FOR USE THEREOF
(FR) COMPOSITIONS FORMANT UNE ÉTANCHÉITÉ AUX FLUIDES DÉGRADABLE, PRÉSENTANT UNE VITESSE DE DÉGRADATION RÉGLABLE, ET LEURS PROCÉDÉS D'UTILISATION
Abstract
(EN)
When performing subterranean treatment operations, it can be desirable to temporarily divert or block fluid flow by forming a degradable fluid seal. Methods for forming a degradable fluid seal can comprise: providing a sealing composition comprising : a degradable polymer, and a water-soluble material comprising a first portion and a second portion of rigid particulates, each portion having a sealing time and a particulate size distribution associated therewith, the particulate size distributions of the first portion and the second portion differing from one another; determining an amount of the first portion relative to the second portion needed to produce a degradable fluid seal having a desired sealing time that is different than that of the sealing time of either the first portion or the second portion; introducing the sealing composition into a subterranean formation; and allowing the sealing composition to form a degradable fluid seal in the subterranean formation.

Lors de la réalisation d'opérations de traitement souterrain, il peut être souhaitable de dévier ou de bloquer temporairement le flux de fluides par la formation d'une étanchéité aux fluides dégradable. Selon l'invention, des procédés de formation d'une étanchéité aux fluides dégradable peuvent comprendre : la mise à disposition d'une composition formant une étanchéité comprenant : un polymère dégradable et un matériau soluble dans l'eau comprenant une première partie et une deuxième partie de particules rigides, chaque partie présentant un temps de formation d'étanchéité et une distribution de tailles de particules associée à celui-ci, les distributions de tailles de particules de la première partie et de la deuxième partie différant les unes des autres ; la détermination d'une quantité de la première partie, par rapport à la deuxième partie, nécessaire pour produire une étanchéité aux fluides dégradable présentant un temps de formation d'étanchéité souhaité qui est différent du temps de formation d'étanchéité de soit la première partie, soit la deuxième partie ; l'introduction de la composition formant une étanchéité dans une formation souterraine ; et la formation d'une étanchéité aux fluides dégradable dans la formation souterraine par la composition formant une étanchéité.
