Title (EN) SYNTHETIC HYDRATABLE POLYMERS FOR USE IN FRACTURING FLUIDS AND METHODS FOR MAKING AND USING SAME
(FR) POLYMÈRES HYDRATABLES SYNTHÉTIQUES DESTINÉS À ÊTRE UTILISÉS DANS DES FLUIDES DE FRACTURATION ET LEURS PROCÉDÉS DE PRÉPARATION ET D'UTILISATION
Abstract:
(EN) Downhole fluid compositions including a base fluid and an effective amount of a synthetic hydratable polymer system including a hydrophobically modified, cross-linked polyacrylate polymer, a hydrophilic, anionic, high molecular weight, cross-linked polyacrylic acid polymer, or mixtures and combinations thereof, where the effective amount is sufficient to achieve a desired viscosity profile and a desired breaking profile in the present of a breaking system in the absence of natural hydratable polymers.
(FR) La présente invention concerne des compositions de fluides de fond de trou comprenant un fluide de base et une quantité efficace d'un système polymère hydratable synthétique comprenant un polymère polyacrylate réticulé modifié de manière hydrophobe, un polymère acide polyacrylique réticulé, de poids moléculaire élevé, anionique, hydrophile, ou des mélanges et des combinaisons de ceux-ci, ladite quantité efficace étant suffisante pour obtenir un profil de viscosité souhaité et un profil de rupture souhaité en présence d'un système de rupture et en l'absence de polymères hydratables naturels.
