Ammonium Persulfate Encapsulated Breaker Hydraulic Fracturing Fluid Gel Breaker-Low Temperature Customized Products-01

Introduction

Proppant-pack permeability can be severely damaged by gelling agents such as guar or its derivatives. The amount of damage increases as polymer concentration increases. Breakers are used to reduce the viscosity of the fracturing fluid by degrading the polymer that is concentrated in the proppant pack. Encapsulated Breaker is the encapsulated version of, which is used for breaking polymers in fracturing fluids at high temperatures.

Chemical Properties and Application

Encapsulated Breaker is a particulate material with specific size produced by a thicker coating (encapsulating) of live with a water-resistant barrier. Encapsulation of the breaker greatly reduces fracturing fluid exposure to the breaker and enables the use of high concentrations of breaker that, without coating, would rapidly reduce the fluid viscosity. Encapsulated Breaker cannot leak off and be lost to the formation, Encapsulated Breaker remains in the fracture where it is needed to degrade concentrated polymers. After the fracturing treatment, release of the breaker occurs as reservoir temperature increase and the fracture closes.
The effective working temperature for Encapsulated Breaker is in the range of 200-350oF (93 to 177oC).
Encapsulated Breaker can be used in most guar and derivative based fracturing fluid systems. It is compatible with most additives used in these systems except for reducers, acids, salts, and other oxidizers, which require extra care to confirm using them together.
