The present disclosure relates to systems and methods for using aldehydes as a catalyst for oxidative breakers. An embodiment of the present disclosure is a method comprising: providing a treatment fluid that comprises: an aqueous base fluid, a polymeric gelling agent, a breaker that comprises an oxidative salt, and a catalyst that comprises an aldehyde; allowing the breaker to interact with the polymeric gelling agent; and allowing the viscosity of the treatment fluid to reduce. L'invention concerne des systèmes et des procédés d'utilisation d'aldéhydes comme catalyseur pour agent de rupture oxydative. Dans un mode de réalisation, l'invention concerne un procédé consistant à utiliser un fluide de traitement qui comprend : un fluide de base aqueux, un agent gélifiant polymère, un agent de rupture oxydative qui comprend un sel oxydant et un catalyseur qui comprend un aldéhyde; à amener l'agent de rupture oxydative à interagir avec l'agent gélifiant polymère; et à permettre la réduction de la viscosité du fluide de traitement.
