Title
(EN) HIGH VISCOSITY FRICTION REDUCER FOR FRACTURING FLUID
(FR) RÉDUCTEUR DE FRICTION À HAUTE VISCOSITÉ POUR FLUIDE DE FRACTURATION
Abstract
(EN) A friction reducer includes a polysaccharide-graft-water-soluble polymer is provided. A polysaccharide in an amount of from about 0.1 to 50% by weight (wt.%) may make up the polysaccharide-graft-water-soluble polymer. A wellbore treatment fluid is provided that includes an aqueous base fluid and the friction reducer in an amount up to about 10% of the wellbore treatment fluid. A method of using a wellbore treatment fluid includes the step of introducing the wellbore treatment fluid as previously provided into a wellbore.
(FR) L’invention concerne un réducteur de friction comprenant un polymère soluble dans l’eau greffé sur un polysaccharide. Un polysaccharide en une quantité d’environ 0,1 à 50 % en poids (%-p) peut réaliser le polymère soluble dans l’eau greffé sur un polysaccharide. L’invention porte sur un fluide de traitement de puits de forage, qui comprend un fluide de base aqueux et un réducteur de friction en une quantité allant jusqu’à environ 10 % du fluide de traitement du puits de forage. Un procédé d’utilisation d’un fluide de traitement de puits de forage comprend l’étape d’introduction du fluide de traitement de puits de forage, telle que présentée ci-dessus, dans un puits de forage.
