Oxidizing Breakers

Sunita offers a diverse range of breaker agents designed to effectively degrade both gelling agents and friction reducers. Through the thermal degradation of oxidizing breakers, free radicals are generated, which target the polymer backbone, cleaving it into smaller segments and thereby diminishing viscosity. This process enables the fracturing fluid’s viscosity to be lowered to levels comparable to water, facilitating a more efficient fluid return to the surface. Oxidizing breakers are available in both liquid and solid forms. Common examples include sodium and ammonium persulfate, which act as non-delayed breakers, initiating viscosity reduction at temperatures exceeding 120°F. However, an activator is necessary for lower temperature applications.

Encapsulated Breakers

Encapsulated breakers are engineered to gradually release an oxidizing agent, serving as an effective breaker in guar and guar derivative-based fracturing fluids operating at temperatures below 300˚F. This innovative solution enables the use of higher concentrations of breaker without compromising fluid viscosity during proppant placement. Consequently, operators gain flexibility in controlling the timing of fluid break or have the option to employ increased breaker concentrations for enhanced performance. Increased breaker concentrations often improve proppant pack clean-up, thereby bolstering fracture conductivity. Sunita offers encapsulated Ammonium Persulfate tailored for delayed applications at moderate temperatures, as well as encapsulated Sodium Bromate optimized for high-temperature environments.

Enzyme Breakers

Sunita provides enzyme breakers meticulously crafted for breaking down Guar polymer. These specialized enzymes efficiently decrease fluid viscosity, even in temperatures reaching up to 250°F. Notably, enzymes remain active throughout the breaking process, persisting over time. This continuous action enables the gradual reduction of polymer segments into shorter, cleaner fragments, resulting in a more refined broken fluid.
