Using the dinitrosalicylic acid methodology –DNS-, were evaluated seven breakers to degrade the polymer used in the water-based fracturing fluids. Four of them, including different oxidizing agents and an inorganic acid are traditionally used in hydraulic fracturing operations. The three additional breakers were proposed in this study and corresponded to two organic acids and a commercial enzyme. Evaluations were performed at three temperatures: 60, 80 and 100 ° C in a time not more than 24 hours of reaction. It was evident that some traditional breakers that reduce the viscosity of fracturing fluids are not effective to degrade the polymer and could increase the polymeric damage in the porous system and in the fractured formation. The commercial enzyme showed better degradation results than oxidants, although its catalytic activity decreased at high temperatures. Acids presented great efficiency to degrade the polymer in the fracturing fluids. However, organic acids require special conditions of time and temperature to activate and degrade the polymer.
