Our enzyme technologies are designed to deliver controlled polymer degradation with lower residue formation and improved system cleanliness—supporting safer handling and more sustainable operations.
Enzyme gel breakers selectively degrade polymer chains such as guar gum and starch without generating aggressive oxidation by-products. This enables controlled viscosity reduction, lower residue formation, and reduced formation damage compared to oxidizer breakers.
Our enzyme systems are designed to break down:
These polymers are commonly used in drilling, fracturing, and completion fluids.
Most oilfield enzymes operate effectively between 40°C and 120°C, depending on grade, exposure time, and fluid chemistry. Higher temperatures typically accelerate gel breaking activity.
Yes. GEPZYMES® enzyme solutions are biobased and biodegradable, making them environmentally compatible alternatives to conventional chemical breakers in many oilfield systems.
No. Enzymes are designed for selective polymer degradation and help reduce polymer residue that could otherwise impair formation permeability and hydrocarbon flow.
Typical dosage ranges from:
0.05% – 0.50%
Actual dosage depends on:
Lab testing is recommended for optimization.
Yes. Oilfield enzymes are formulated to remain functional in fresh water as well as high-salinity brines used in drilling and completion operations.

Our technical team can recommend the most suitable BIOBREAKER™, BIOFILTER™, or BIOMUD™ grade after lab evaluation.
| Parameter | Typical Operating Window | Remarks |
| Temperature | 40–120°C | Activity depends on grade & exposure time; higher temperatures generally accelerate breaking |
| pH Range | 4.5–9.0 | Works in most drilling/completion fluid pH ranges; extreme pH can reduce activity |
| Salinity / Brine Tolerance | Fresh water to high-salinity brines | Designed for compatibility with common oilfield brines and salts (grade-dependent) |
| Polymer Compatibility | Guar, modified guar, starches, cellulose derivatives, xanthan blends | Select grade based on polymer system and target break profile |
| Contact Time | 0.5–24 hours | Controlled break: shorter for cleanup; longer for delayed breaking (system-specific) |
| Typical Dosage | 0.05–0.50% (on fluid / polymer system) | Dosage depends on polymer loading, temperature, pH, salinity, and desired break time |
| Shear Compatibility | High-shear mixing compatible | Add under circulation/mixing; avoid localized overdosing |
| Recommended Addition Point | Mixing tank / hydration stage / pre-flush / cleanup pill | Choose based on application: viscosity control, filter cake removal, or mud cleanup |
| Oxidizer Compatibility | Not recommended with strong oxidizers | Strong oxidizers can deactivate enzymes; consult if oxidizers are present |
| Surfactant / Biocide Tolerance | Generally compatible (grade-dependent) | Some biocides/surfactants can reduce activity; best practice is jar testing |
Enzymes such as amylases, cellulases, and mannanases effectively degrade polymers like starch, cellulose, and xanthan gum present in drilling fluids. This enables thorough wellbore cleaning, reducing filter cake thickness and improving drilling efficiency. Enzymatic cleaning is safer and more environmentally friendly compared to harsh oxidizers or acids, ensuring smooth well operations and reduced downtime.
Enzymes assist in breaking down organic deposits, waxes, and polymer residues in reservoirs, improving permeability and fluid flow. Their ability to degrade organic blockages enables increased hydrocarbon recovery from mature wells without damaging formation integrity. Enzymatic EOR solutions are eco-friendly and compatible with a wide range of oilfield conditions, supporting sustainable production enhancement.
Enzymatic gel breakers efficiently break down guar gum, xanthan gum, and other biopolymers used in fracturing fluids. This ensures controlled viscosity reduction, efficient proppant placement, and smooth flowback, minimizing formation damage. Compared to chemical breakers, enzymes work at lower dosages and produce fewer undesirable residues, optimizing fracturing operations while lowering environmental footprint.
Enzymes and enzyme-based microbial blends are used to degrade hydrocarbons and other organic contaminants in drilling muds, cuttings, and produced water. This facilitates safe disposal or recycling of oilfield waste while reducing environmental liability. Enzymatic bioremediation supports compliance with environmental regulations and helps oil & gas companies meet sustainability goals.
