Starch Breaker Pro is an enzyme blend containing alpha-Amylase (high temperature), alpha-Amylase (medium temperature), beta-Amylase, for laboratory evaluation of susceptible polymers in drilling fluids and oilfield cleanup treatments. Screen polymer breakdown, rheology and filter-cake cleanup under representative process conditions.
Application benefits
- Targeted enzymatic cleavage of susceptible starch polymers.
- Evaluate viscosity reduction and polymer-residue removal in your complete fluid.
- Available in 1 L, 10 L and 25 L liquid enzyme packs, with technical support and bulk supply.

The product photograph shows the 1 L pack. Select 10 L or 25 L for the corresponding larger liquid enzyme pack.
How to evaluate
- Identify the polymers and obtain representative fluid and filter-cake samples.
- Compare untreated controls with enzyme doses and treatment times under actual process conditions.
- Measure rheology, polymer breakdown and cleanup; assess filter-cake removal and permeability before planning a field treatment.
Complementary products & formulation notes
Cellulose Breaker Pro can complement amylase where the fluid also contains susceptible cellulose derivatives. Add Xylan Breaker Pro only where xylan is present.
- Cellulose Breaker Pro — select by the polymer present in your fluid.
- Xylan Breaker Pro — select by the polymer present in your fluid.
Blend ratios require testing. These enzymes do not directly digest petroleum hydrocarbons or dissolve mineral bridging solids.
