Hydraulic fracturing fluids rely on polymers — primarily guar and derivatized guar — to carry proppant into the fracture. After placement, residual polymer remains in the proppant pack and on formation faces, restricting fracture conductivity, reducing permeability, and limiting production.
This damage directly impacts well economics. Even small reductions in proppant pack conductivity translate to significant production losses over the life of the well.
Conventional oxidizer breakers underperform. Independent testing at PropTester showed ammonium persulfate recovering as little as 20% conductivity at 80°F and 49% at 120°F — leaving the majority of polymeric damage in place. Oxidizers react stoichiometrically and are consumed in the reaction, limiting their effectiveness.
Hallux enzyme breakers are biological catalysts specifically engineered to degrade the polymers used in fracturing fluids. Unlike oxidizers that are consumed in a single reaction, enzymes continue working until the polymer is fully degraded — restoring proppant pack conductivity to near-original levels.
Each enzyme system targets a specific polymer type, ensuring complete and predictable cleanup without damaging the formation, proppant, or other fluid components.
Our patented Mannanase systems are the flagship — seventh-generation guar-specific enzymes with temperature-activated, delayed-break design. They remain stable during mixing and pumping at surface, then become maximally active under downhole conditions.
For completions using xanthan, starch, or cellulose-based fluids, Hallux also offers Xanthanase, Amylase, and Cellulase enzyme systems — each purpose-built for its target polymer.
Temperature-Activated Design
Enzymes remain stable at surface temperatures and activate at reservoir conditions — eliminating the risk of premature fluid break during pumping and proppant placement.
Complete Polymer Degradation
Enzymes degrade polymers to very low molecular weight fragments. Reduced viscosity alone does not indicate a broken fluid — Hallux enzymes ensure actual cleanup at the molecular level.
Independent Study Validation
Four independent fracture modeling studies across Cotton Valley, Bakken, Spraberry, and Niobrara basins confirm 20–65% production uplift using Hallux enzyme breakers.
Non-Hazardous & Made in USA
All Hallux enzymes are manufactured in the USA, environmentally friendly, not DOT regulated, and compatible with fresh, brackish, high-salinity, produced, and recycled waters.
Patented, seventh-generation guar-specific enzyme breakers. Independent lab testing shows 90–100% regained conductivity across temperatures from 80°F to 315°F — with 20–60% production uplift compared to oxidizer breakers.
The only patented enzyme breaker purpose-built for xanthan gum. Restores formation permeability and proppant pack conductivity to near-original levels in completions using xanthan-based fluids. No competitive equivalent exists on the market.
Specifically engineered to degrade starch-based polymers used in drilling and fracturing fluids. Targets starch viscosifiers and fluid loss control agents, restoring permeability in formations damaged by starch-based systems.
Engineered to degrade cellulose and cellulose derivatives (CMC, HEC, PAC) used as viscosifiers and fluid loss control agents in drilling and fracturing fluids. Restores formation permeability by eliminating cellulose-based polymer damage.
Not all enzymes are created equally. Hallux enzyme breakers deliver 90–100% regained conductivity and 20–65% production uplift over conventional oxidizer breakers — validated by independent laboratory testing and fracture modeling studies across four major US basins. Each enzyme system targets a specific polymer type for complete, predictable cleanup.
