Title (EN) HYDROCARBON-BASED FILTERCAKE DISSOLUTION FLUID
(FR) FLUIDE DE DISSOLUTION DE GÂTEAU DE FILTRATION À BASE D'HYDROCARBURES
Abstract: front page image
(EN)Embodiments of this invention relate to a composition and a method for dissolving a filtercake in a subterranean formation comprising forming a mixture comprising a dissolution fluid and a fluid comprising hydrocarbon; introducing the mixture into a subterranean formation containing a filtercake; introducing an aqueous fluid to the mixture; and dissolving the filtercake. Embodiments of this invention also relate to further exposing the mixture to swellable packer. Embodiments of this invention relate to a method for a composition, comprising a fluid comprising hydrocarbon; and a dissolution fluid, wherein the fluid comprising hydrocarbon and dissolution fluid are combined to form a miscible mixture that dissolves a filtercake in a subterranean formation.
(FR)Des modes de réalisation de cette invention portent sur une composition et un procédé pour dissoudre un gâteau de filtration dans une formation souterraine comprenant la formation d'un mélange comprenant un fluide de dissolution et un fluide comprenant des hydrocarbures ; l'introduction du mélange dans une formation souterraine contenant un gâteau de filtration ; l'introduction d'un fluide aqueux dans le mélange ; et la dissolution du gâteau de filtration. Des modes de réalisation de cette invention portent également sur une nouvelle exposition du mélange à une garniture d'étanchéité gonflable. Des modes de réalisation de cette invention portent sur un procédé pour une composition, comprenant un fluide comprenant des hydrocarbures ; et un fluide de dissolution, le fluide comprenant des hydrocarbures et le fluide de dissolution étant combinés pour former un mélange miscible qui dissout un gâteau de filtration dans une formation souterraine.
