Encap-SB High Temperature (HT) is an encapsulated viscosity modifier for use as a delayed release breaker in hydraulic fracturing applications. Encap-SB HT slowly releases Sodium Bromate breaker into the fracturing fluid, thus enabling a higher concentration of breaker to be used without fluid rheology being compromised. This product is a solid form of breaker that is not lost within the proppant pack during fluid leak-off. Encap-SB HT can be used in fracturing fluids with temperatures of 280°F to 330°F.
Encap-SB HT can be substituted for persulfate breakers currently used at temperatures above 250°F. With any fracturing application, we recommend that break tests be conducted with the fluid formulations to determine the best possible concentrations.
