Title (EN) FLUID LOSS ADDITIVE AND BREAKING AGENT
(FR) ADDITIF CONTRE LA PERTE DE FLUIDE ET AGENT DE FRACTURATION
Abstract:
(EN) A system includes a hydraulic fracturing fluid including a polymeric constituent and an additive having particles including poly-vinyl acetate in an amount sufficient to control fluid loss. The system includes a formation of interest having a downhole temperature, and the particles including poly-vinyl acetate have a size and/or shape such that the poly-vinyl acetate hydrolyses at the downhole temperature. The particles may have a size and/or shape such that the particles are deformable at the downhole temperature. The poly-vinyl acetate in the particles may be a part of the particle substrate, a coating on the particles, and/or the entire particle may be poly-vinyl acetate. The poly- vinyl acetate may be included in any portion of the hydraulic fracturing fluid, or only the portion of the hydraulic fracturing fluid that is not proppant laden.
(FR) La présente invention concerne un système qui inclut un fluide de fracturation hydraulique comprenant un constituant polymère et un additif comportant des particules renfermant de l'acétate de polyvinyle dans une quantité suffisante pour contrôler la perte de fluide. Le système inclut une formation d'intérêt se caractérisant par une température de fond, et les particules renfermant de l'acétate de polyvinyle ont une taille et/ou une forme telles que l'acétate de polyvinyle s'hydrolyse à cette température de fond. Les particules peuvent avoir une taille et/ou une forme telles qu'elles sont déformables à la température de fond. L'acétate de polyvinyle peut être présent dans le cœur des particules ou dans un revêtement sur les particules, et/ou constituer la totalité des particules. L'acétate de polyvinyle peut également être inclus dans une quelconque partie du fluide de fracturation hydraulique, ou seulement la partie de ce fluide qui n'est pas chargée en agent de soutènement.
