Title (EN) EMULSION-BASED BREAKER FOR NANOPARTICLE CLAY FLUID
(FR) AGENT DE RUPTURE À BASE D'ÉMULSION POUR FLUIDE ARGILEUX NANOPARTICULAIRE
Abstract:
(EN) A method of treating in a subterranean formation including forming an acid internal/oil external emulsified fluid, wherein the emulsified fluid comprises an oil based fluid, an aqueous fluid, an emulsifier, and an acid; forming a nanoparticle clay fluid, wherein the fluid comprises a nanoparticle clay, a gelling agent, and a crosslinking agent; combining the emulsified fluid and the nanoparticle clay fluid to form a treatment fluid; introducing the treatment fluid into the subterranean formation; breaking the acid internal/oil external emulsion fluid portion of the treatment fluid, thereby releasing the acid; and breaking the nanoparticle clay fluid portion of the treatment fluid with the released acid. Treatment fluids include an acid internal/oil external emulsified fluid, wherein the emulsified fluid comprises an oil based fluid, an aqueous fluid, an emulsifier, and an acid; and a nanoparticle clay fluid, wherein the fluid comprises a nanoparticle clay, a gelling agent, and a crosslinking agent.
(FR) L'invention concerne un procédé de traitement dans une formation souterraine comprenant la formation d'un fluide émulsifié interne acide/externe huileux, le fluide émulsifié comprenant un fluide à base d'huile, un fluide aqueux, un émulsifiant et un acide; la formation d'un fluide argileux nanoparticulaire, le fluide comprenant une argile nanoparticulaire, un agent gélifiant et un agent de réticulation; la combinaison du fluide émulsionné et du fluide argileux nanoparticulaire pour former un fluide de traitement; l'introduction du fluide de traitement dans la formation souterraine; la rupture de la partie fluide interne acide/externe huileuse du fluide de traitement, libérant ainsi l'acide; et la rupture de la partie fluide argileux nanoparticulaire du fluide de traitement avec l'acide libéré. Les fluides de traitement comprennent un fluide émulsifié interne acide/externe huileux, le fluide émulsifié comprenant un fluide à base d'huile, un fluide aqueux, un émulsifiant et un acide; et un fluide argileux nanoparticulaire, le fluide comprenant une argile nanoparticulaire, un agent gélifiant, et un agent de réticulation.
