Fracturing fluids are used for viscosity and proppant transport during hydraulic fracturing operations. These breakers are important in fracturing fluid to extensively degrade the polymer mass after fracturing operations reducing viscosity and thereby maximizing fracture conductivity with minimum residual damaging.
A fracturing fluid are made with higher viscous Gel loaded with proppant silica or Ceramic Proppant with the polymeric material this includes Guar Gum, Xanthan or hydrophilic polymeric along with water and Oil.
Usually Frac Proppant Gel is then pumped into a well bore at an appropriate rate and pressure to produce lateral fractures to open access to surrounding crude oil and natural gas.
Geocon Products manufacture EXPLORAX BRK Enzyme for Guar and Xanthan based breaking through Bio Process when injected the high viscosity fracturing fluid to immediately lower the viscosity. This allow controlled release time and the fluid to enter into cracks while leaving the proppant in position to hold the fracture open.
In Oil well applications Enzymes have been used successfully as breakers for fracturing fluids for many years. Enzymes are more polymer specific, environmentally friendly, easy & safe to handle, completely miscible in the fluid system, Equipment friendly. When we compare with the Oxidizers on the other hand, they are not environmentally nor equipment friendly. Oxidizers affect the activity of enzymes when mixed.
Activity of EXPLORAX GEL BREAKER and How it works?
Enzymes are proprietary blends and made suitable for gel breaking activity. The class hemicellulose and Mannanase Group, which cause reduction of the guar molecular weight. Enzymes are very economical and easier to handle but have some limitations of pH and temperature. The breaking two mannan groups leads to an immediate reduction in the average molecular weight, and hence reduction in viscosity.
Handling and Storage
EXPLORAX BREAKER should be stored in a cool, dry location. Shelf-life is typically 2 years but can be extended by storing under refrigeration. Keep all containers tightly closed.
EXPLORAX BREAKER is non-toxic. It may be irritating if contacted with the eyes. It may irritate the skin of extremely sensitive individuals.
Chemical splash goggles and impervious gloves are recommended when handling Refer to the Material Safety Data Sheet for more detailed information.
