Common frac fluid breakers include chemical oxidizers such as hydrogen peroxide and persulfates or organic acids. However, enzyme-based breakers such as hemicellulase, cellulose, amylase and pectinase have been widely used in water-based fracturing fluids for three decades. Enzyme breakers have several advantages over traditional oxidizer chemicals.

CROSS-LINKERS FOR HYDRAULIC FRACTURING FLUID

The ,fracturing fluid, is also ,used, to carry sand or other types of particles, called proppants, to hold the cracks open when the pressure is relieved. The cracks held open by the proppant provide additional paths for the oil or natural gas to reach the wellbore, which, in turn, increases the production of oil and/or natural gas from the well.
