Mannanase HT 20K

Applications

Hallux Mannanase HT (High Temp) Enzymes (US Patent #10,227,523, 1 1,401,457 and 12,227,695) are highly efficient, specifically engineered enzymes to degrade guar and derivatized guar polymers under extreme bottom-hole conditions. Hallux Mannanase HT is also specifically engineered to optimize proppant pack conductivity and regained permeability providing for potentially higher well productivity at elevated temperatures. A unique feature of these seventh generation enzymes is that they are stable but show minimal activity under mixing conditions and/or pumping at ambient temperatures and below 110°F. However, under down-hole conditions of high temperature and pH, Hallux Energy Mannanases become maximally active and rapidly and virtually completely break any polymeric damage in the proppant pack or formation faces, thereby optimizing well productivity. Frac Design Models and Case Studies have shown production uplifts between 20-60% compared to Oxidative breakers and other enzymes.

Independent Laboratory testing show proppant pack Regained Conductivities between 90%-100% at 140°F, 180°F, 250°F and 315°F within 24 hours of flowback, when utilizing Hallux Mannanase HT.

Effective Temperatures 110°F-315°F+. Can be used in fluids with a pH range from 3 to 12.

All Hallux Enzymes are Non-Hazardous, Not DOT Regulated, Environmentally Friendly products.

Features

High Efficiency

Enzyme complex attacks, or has an affinity toward, specific polymer linkages resulting in mono-and di-saccharides, which maximizes degradation efficiency.

Customization

Hallux Energy enzymes are custom-designed for any guar or derivatized guar polymer.

Unique Chemistry

Enzymes do not undergo chemical or structural changes during the reactions they initiate and do not produce undesirable side reactions. They have a unique property called “turn-over” number. Typical “turn-over” numbers are in excess of one million which means that more than one million linkages of polymer substrate can be cleaved per minute. A great many more can be cleaved over the “life span” of the enzyme unit.

Temperature Stability

Stable at temperatures up to 315°F (157°C). Recent advances in biotechnology allow for extreme temperature applications.

pH Stability

Effective in fluids that range in pH from 3 to 12. Recent advances in biotechnology also allow for broader pH applications.

Non-Hazardous

Produced from all natural processes.

Compatibility

Compatible with all types of formations, base waters, tubular goods and proppants (especially resin-coated proppants).

Benefits

Independent Laboratory Proppant pack testing has shown that retained conductivities approaching 100% are possible.

Mannanase LT 20K

Applications

Hallux Mannanase LT (Low Temp), which are highly efficient, specifically engineered enzymes to degrade guar and derivatized guar polymers under extreme bottom-hole conditions. Hallux Mannanase LT is also specifically engineered to optimize proppant pack conductivity and regained permeability providing for potentially higher well productivity at low to medium temperatures.

Independent Laboratory testing has shown proppant-pack Regained Conductivities and “filter-cake degradation” regained conductivities in excess of 90% at 80°F and 160°F, when utilizing Hallux Mannanase LT Enzymes. Effective Temperatures 80°F-160°F. Can be used in fluids with a pH range from 3 to 10.

Cost effective. High retained conductivity and high regained permeability result in high productivity, which is a cost savings for the operator.

Non-corrosive to any metals which may be encountered in the well.

Highly compatible, with the only affinity toward specific linkages in the guar molecule; does not react with anything else.

Safety Precautions

Although prolonged contact and breathing can produce an irritation in sensitized people, there are no special storage, handling, toxicity or environmental precautions necessary.

Limitations

Suggested maximum temperature of 315°F (157°C).

Competitive Products

None.

Field Proven

Reported in the Bakken Scout, volume 6 number 3, produced Feb 26, 2019, Bruin Bakken HZ delivers ~100,000 bo in 30 days by using Hallux Energy’s patented Mannanase enzyme, which is the third-highest oil volume delivered by a well in the basin. In 2018, Bruin E&P stimulated 33 wells in the Bakken Formation, of which 30 of the wells were fracture stimulated by a crosslinked guar fluid containing Hallux Energy’s patented Mannanase. The remaining 3 wells were stimulated with a High-Viscosity FR fluid with similar proppant/ sand volumes as the crosslinked wells. All the wells fraced with the crosslinked gels and patented enzymes greatly outperformed the wells fraced with High-Vis FRs.
