Title (EN) ENHANCED HIGH TEMPERATURE CROSSLINKED FRACTURING FLUIDS
(FR) FLUIDES DE FRACTURATION RÉTICULÉS À HAUTE TEMPÉRATURE AMÉLIORÉS
Abstract:
(EN) A fracturing fluid including a mixture of an aqueous terpolymer composition including a terpolymer, an additive, and crosslinker. The terpolymer includes 2-acrylamido-2-methylpropanesulfonic acid, acrylamide, and acrylic acid monomer units, or a salt thereof. The additive includes a sugar alcohol or a derivative thereof, and the crosslinker includes a metal. The weight ratio of the metal to the terpolymer is in a range of 0.01 to 0.16, and a concentration of the additive is in a range of 0.001 wt.% to 10 wt.% of the fracturing fluid. Treating a subterranean formation includes introducing the fracturing fluid into a subterranean formation, and crosslinking the fracturing fluid in the subterranean formation to yield a crosslinked fracturing fluid. The crosslinked fracturing fluid mitigates damage caused by substantial amounts of total dissolved solids or significant water hardness.
(FR) L’invention concerne un fluide de fracturation comprenant un mélange d'une composition terpolymère aqueuse comprenant un terpolymère, un additif et un agent de réticulation. Le terpolymère comprend de l'acide 2-acrylamido-2-méthylpropanesulfonique, de l'acrylamide et des unités monomères d'acide acrylique, ou un sel de ceux-ci. L'additif comprend un alcool de sucre ou un dérivé de celui-ci, et l'agent de réticulation comprend un métal. Le rapport en poids du métal au terpolymère est dans une plage de 0,01 à 0,16, et une concentration de l'additif est dans une plage de 0,001 % en poids à 10 % en poids du fluide de fracturation. Le traitement d'une formation souterraine comprend l'introduction du fluide de fracturation dans une formation souterraine, et la réticulation du fluide de fracturation dans la formation souterraine pour produire un fluide de fracturation réticulé. Le fluide de fracturation réticulé atténue les dommages causés par des quantités importantes de solides dissous totaux ou de dureté d'eau significative.
