Title (EN) HIGH TEMPERATURE CROSSLINKED FRACTURING FLUIDS
(FR) FLUIDES DE FRACTURATION RÉTICULÉS À HAUTE TEMPÉRATURE
Abstract:
(EN) A fracturing fluid including a mixture of an aqueous copolymer composition including a copolymer, the copolymer having 2-acrylamido-2-methylpropanesulfonic acid, acrylamide, and acrylic acid monomer units, or a salt thereof, and a crosslinker. The crosslinker includes a metal, and the weight ratio of the metal to the copolymer is in a range of 0.01 to 0.08. 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 has a viscosity of at least 500 cP for at least 80 minutes when the gel is subjected to a shear rate of 40 s-1 at a temperature in a range of 300°F to 400°F.
(FR) L'invention concerne un fluide de fracturation comprenant un mélange constitué d'une composition aqueuse de copolymère comprenant un copolymère, le copolymère comportant des motifs monomères d'acide 2-acrylamido-2-méthylpropanesulfonique, d'acrylamide et d'acide acrylique, ou un sel de ceux-ci, et un agent de réticulation. L'agent de réticulation comprend un métal, et le rapport pondéral du métal au copolymère est compris dans la plage allant de 0,01 à 0,08. Le traitement d'une formation souterraine consiste à introduire le fluide de fracturation dans une formation souterraine, et à réticuler le fluide de fracturation dans la formation souterraine pour obtenir un fluide de fracturation réticulé. Le fluide de fracturation réticulé possède une viscosité supérieure ou égale à 500 cP pendant au moins 80 minutes lorsque le gel est soumis à un taux de cisaillement de 40 s-1 à une température comprise dans la plage allant de 300 °F à 400 °F.
