Xanthanase HT 20K

Applications

Hallux Xanthanases are highly efficient, patented (WO2019022789), specifically engineered enzymes to degrade Xanthan polymers under extreme bottom-hole conditions. Hallux Xanthan Enzyme is also specifically engineered to be most effective in open-hole drilling and drill-in fluid clean-ups, by maximizing regained permeability providing for potentially higher well productivity at elevated temperatures. Hallux Energy Xanthanases can also be effectively applied to Drill-Out applications, in order to minimize damage produced by Drill-Out fluid losses

Independent Laboratory testing have shown regained permeability and “filter-cake degradation” testing in excess of 90%, when utilizing Hallux Xanthan Enzymes. Effective Temperatures 100°F-275°F.

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

Features

Removes Filter Cake Damage

Removes filter cake damage created by drill-in fluids comprised of either starch, cellulose polymers, xanthan polymers, sized calcium carbonate or salt particulates.

Improves Fracture Conductivity

High Efficiency

Each of the enzymes utilized attack, or have an affinity toward, specific polymers in maximum degradation efficiency.

Customization

Polymer-specific enzymes allow each treatment to be customized for the specific type of polymeric damage.

Unique Chemistry

Enzymes do not undergo chemical or structural changes during the reactions they initiate and do not produce undesirable side reactions. They also possess an 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 275°F (135°C).

pH Stability

Effective in fluids that range in pH from 3 to 11. Recent advances in biotechnology have allowed for broader pH applications.

Non-Hazardous

Produced from all natural processes.

Compatibility

Compatible with all types of formations, base waters, tubular goods and proppants.

Benefits

Independent Laboratory Regained Permeability testing has shown that regained results can approach 100%.

Treatments are customized to the type of damage present, creating maximum cost and performance efficiency.

Applicable to a broad range of downhole temperatures.

Low and high pH stability of the enzymes allow for use in all fracturing fluids.

Environmentally friendly. Enzymes do not require any special handling or disposal.

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

Effective as a remedial treatment to clean up inadequately broken frac fluids.

Noncorrosive to any metals which may be encountered in the well.

Safety Precautions

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