SL-EBR02 is an encapsulated version of a peroxide breaker, it can be used in most guar or guar derivative based fracturing fluids, and polymer fracturing fluids.
Breaker
LT Encapsulated Gel Breaker SL-EBR02
Proppant-pack permeability can be severely damaged by gelling agents such as guar or polymers. The amount of damage increases as polymer concentration increases. Breakers are generally used to reduce the viscosity of the fracturing fluids by degrading the polymer that is concentrated in the proppant pack.

Product Description
Technical & Engineering Information
SL-EBR02 is a particulate material with specific size produced by coating (encapsulating) a peroxide breaker with a water-resistant barrier. If it is not encapsulated, the breaker will quickly reduce the fluid viscosity. The encapsulation of the breaker greatly reduces the contact between the fracturing fluid and the breaker, without coating, would reduce the fluid viscosity.
SL-EBR02 cannot leak off and be lost to the formation, SL-EBR02 remains in the fracture where it is needed to degrade concentrated polymers. After fracturing treatment, the release of the breaker occurs as the reservoir temperature increases and the fracture closes.
SL-EBR02 can be used in most guar gum and polymer based fracturing fluid systems. It is compatible with most additives used in these systems, except for reducing agents or strong oxidizing agents. Care should be taken to avoid the use of reduced additives and stronger breakers together with SL-EBR02.

Recommended Treatment
SL-EBR02 concentration depends on factors such as polymer concentration, temperature, break time requirement, and polymer type. Laboratory testing may be required for optimized breaker schedule design.
Because the breaker chemical is released slowly from SL-EBR02, it is recommended to shut-in at least 12 hours, for wells turn-around times less than 12 hours, a tail-in of breaker SL-BR05 is recommended to provide a more rapid, near-wellbore breaker.
Release Rate @30MPa ≥ 55%
Packing and Storage
SL-EBR02 is supplied in plastic-lined bags with net weight of 25 kg/bag. Keep it away from extreme conditions such as places wet and humid or direct sunlight.
Shelf life:1 year.
