Product Overview
Description
persulfates are commonly used as breakers for aqueous fluids viscosified with guar or cellulose derivatives. These breakers are necessary to minimize permeability damage to proppant packs at temperatures where there is little thermal degradation of the polymers. Unfortunately, dissolved persulfates are much too polymers. Unfortunately, dissolved persulfates are much too reactive, even at moderate temperature (140 to 200 degs F), to be used at concentrations sufficient to degrade concentrated, high-molecular-weight polymers thoroughly.
SJ-11 Encapsulated Breaker is a type of "delayed" breaker. It is prepared by encapsulating ammonium persulfate (APS) with a water-resistant coating. The coating shields the fluid form the breaker so that high breaker concentrations can be added to the fluid without causing the premature loss of fluid properties, such as viscosity or fluid-loss control. SJ-11 Encapsulated Breaker has advantages such as complete gel breaking, high viscosity decreasing rate, easy flowback etc. And it also can improve the permeability of the reservoir and benefit for the fracturing construction.
