Title (EN) COMPOSITIONS AND METHODS FOR DELAYED CROSSLINKING IN HYDRAULIC FRACTURING FLUIDS
(FR) COMPOSITIONS ET PROCÉDÉS POUR UNE RÉTICULATION RETARDÉE DANS DES FLUIDES DE FRACTURATION HYDRAULIQUE
Abstract:
(EN) Disclosed herein are compositions and methods for delaying crosslinking of aqueous crosslinkable polymers such as polysaccharides in injectable compositions for hydraulic fracturing and related applications. The compositions and methods provide delayed crosslinking at high temperatures and pressures, such as those encountered by hydraulic fracturing compositions injected into subterranean environments. Compositions include injectable solutions comprising a competing agent that is a reaction product of a dialdehyde having 2 to 4 carbon atoms with a non-polymeric cis-hydroxyl compound. Provided are methods of making and using delayed-crosslinking compositions comprising crosslinker compositions containing zirconium complexes and the competing agents.
(FR) La présente invention concerne des compositions et des procédés permettant de retarder la réticulation de polymères aqueux réticulables tels que des polysaccharides dans des compositions injectables pour la fracturation hydraulique et des applications associées. Les compositions et procédés permettent de retarder la réticulation à des températures et à des pressions élevées, telles que celles rencontrées par des compositions de fracturation hydraulique injectées dans des environnements souterrains. Les compositions comprennent des solutions injectables, comprenant un agent concurrent qui est le produit de la réaction d'un dialdéhyde comprenant de 2 à 4 atomes de carbone avec un composé à fonction cis-hydroxyle non polymère. L'invention concerne également des procédés de préparation et d'utilisation de compositions à réticulation retardée comprenant des compositions de réticulation contenant des complexes de zirconium et les agents concurrents.
