Title (EN) METHODS AND MATERIALS FOR ZONAL ISOLATION
(FR) PROCEDES ET MATERIAUX POUR ISOLATION ZONALE
Abstract:
(EN) The invention relates to the use of one or more water-soluble reactive liquid component capable of subsequent polymerization or cross-linking to form a solid to improve the zonal isolation and alleviate the impacts of cracks and fissures in the cement sheath around a completed subterranean well. It includes the steps of injecting a wellbore fluid carrying the reactive component or additive into the wellbore, injecting a cementitious composition as slurry into the wellbore and letting said reactive liquid component pass through at least one of the interfaces between cement and formation, cement and filter cake, and filter cake and formation before forming a solid of said reactive liquid component that traverses said at least one of the interfaces.
(FR) L'invention concerne l'utilisation d'au moins un composant liquide réactif hydrosoluble capable de polymérisation ou de réticulation subséquente pour former un solide destiné à améliorer l'isolation zonale et éviter les impacts de craquelures et de fissures dans la gaine en ciment enveloppant un puits souterrain achevé. L'invention concerne notamment une étape d'injection d'un liquide de forage véhiculant le composant réactif ou l'additif dans le forage, une étape d'injection d'une composition à base de ciment telle une suspension épaisse dans le forage et une étape du passage dudit composant liquide réactif traversant au moins une des interfaces entre le ciment et la formation, le ciment et le gâteau de filtration, et le gâteau de filtration et la formation avant de former un solide du composant liquide réactif qui traverse lesdites interfaces.
