Title (EN) METHOD FOR PROVIDING ZONAL ISOLATION IN AN UNDERGROUND WELLBORE
(FR) PROCÉDÉ DE RÉALISATION D’ISOLATION ZONALE DANS UN PUITS DE FORAGE SOUTERRAIN
Abstract:
(EN) Slugs of a cement slurry and of a resin composition are injected into an underground wellbore. The resin composition contains at least a curable resin, a filler, a swelling agent, a curing initiator, and a crosslinking retarding agent. The curing initiator activates the curing in response to temperature. The crosslinking retarding agent delays curing of the resin, to permit pumping the composition into the wellbore. After injection, the cement slurry and resin composition are allowed to cure, to create a stacked cement and cured resin column that provides a zonal isolation seal within the wellbore. The resin composition may suitably be an elastomer-forming composition. The cured resin may be swellable by allowing contact with a wellbore fluid.
(FR) La présente invention décrit des bouchons de suspension de ciment et d’une composition de résine injectés dans un puits de forage souterrain. La composition de résine contient au moins une résine durcissable, une charge, un agent gonflant, un initiateur de durcissement, et un agent de retardement de réticulation. L’initiateur de durcissement active le durcissement en réponse à la température. L’agent de retardement de réticulation retarde le durcissement de la résine, afin de permettre le pompage de la composition dans le puits de forage. Après l’injection, la suspension de ciment et la composition de résine sont laissées à durcir, pour créer une colonne de ciment et de résine durcie empilés qui fournit un joint d’isolation zonale à l’intérieur du puits de forage. La composition de résine peut de manière appropriée être une composition formant un élastomère. La résine durcie peut gonfler en permettant le contact avec un liquide de puits de forage.
