DESCRIPTION- EB-1 and EB-10 are two enzyme based fracturing fluid breakers. The enzyme contained in these breakers is a hemicellulase derived from the fermentation of Aspergillus niger. EB-10 is approximately 10 times more active than EB-1. Both breakers are readily soluble in water if a liquid is
preferred.

ADVANTAGES
• EB-1 and 10 are powders that are readily soluble in water on location.
• EB-1 and 10 can be packaged and labeled to meet your requirements, including in water-soluble bags.
• Quality assurance insures consistent break times with each batch of EB-1 and 10.

APPLICATION
• EB-1 and 10 can be used in fracturing fluids below pH 9 and 140°F.
• EB 1 and 10 may be used in conjunction with delayed release acids (EnCap-A or SBS) in high pH fluids below
120°F. After the pH of the fluid decreases due to released acid, the enzyme will activate and break the fluid.
