Title (EN) HIGH-SALT GELLING COMPOSITION FOR WELL TREATMENT
(FR) COMPOSITION GÉLIFIANTE RICHE EN SEL POUR LE TRAITEMENT DE PUITS
Abstract: front page image
(EN) A fluid including: (i) a continuous aqueous phase, wherein the continuous aqueous phase has total dissolved solids in a concentration of at least 30,000 mg/l; (ii) an alkyl amido quaternary amine; (iii) a polymer, wherein the polymer is water-soluble or water-hydratable; and (iv) a crosslinker for the polymer. The continuous aqueous phase of the fluid can include a water source selected from the group consisting of flowback water, produced water, and any combination thereof. Methods include: (A) forming a fluid according to any of the various embodiments of the disclosure, and (B) introducing the fluid into a well. For example, the fluid can be used as a fracturing fluid for fracturing a treatment zone of a well.
(FR) L'invention concerne un fluide comprenant : (i) une phase aqueuse continue, la phase aqueuse continue possédant une teneur totale en solides dissous en une concentration d'au moins 30 000 mg/l ; (ii) une amine quaternaire alkylamido ; (iii) un polymère, le polymère étant hydrosoluble ou hydratable par l'eau ; et (iv) un agent de réticulation pour le polymère. La phase aqueuse continue du fluide peut comprendre une source d'eau choisie dans le groupe constitué de l'eau de reflux, l'eau produite et n'importe quelle combinaison de celles-ci. Les procédés consiste à : (A) former un fluide selon l'un quelconque des divers modes de réalisation de la description et (B) introduire le fluide dans un puits. Par exemple, le fluide peut être utilisé en tant que fluide de fracturation pour la fracturation d'une zone de traitement d'un puits.
