Abstract

The relative reduction in proppant-pack permeability caused by the residue remammg after injecting slickwater. Even small concentration of polymer can lead damage in proppant-pack permeability. The productivity of the well directly depends on clean-up proppant-pack. Clean-up is achieved by "breaking" fracturing fluid, reverting to a thin, water-like condition. Chemical additives, which reduce fluid viscosity, called breakers. They can be oxidizers and enzymes. Breaker performance depends on bottombole temperature, breaker concentration and polymer concentration. Different type of breakers gives different results according to concentration and working temperature. The project was aimed at studying effectiveness of breakers in cleaning. Concentration of breakers was optimized. Results were given by varying the breaker concentration adjusting temperature. Viscosity profiles were improved for every breaker. Break time was detected by using viscometer, which shows time where breaker works at full capacity. This study provides bet1er understanding of various breaker type performance and optimization of breaker concentration in order to get better results and minimum damage caused by polymer degradation.
