Improved oil production or water injectivity
Removing a flow-restricting filter cake can reduce resistance between the reservoir and the well, helping recover production or water injectivity.
Target starch, cellulose and xylan polymers in drilling fluids. Build your cleanup programme with specialist enzyme blends, bulk supply and dedicated technical support.

Targeted polymer removal can support better reservoir-to-well flow, less residual formation damage and more selective cleanup. For long intervals, optimise treatment placement and reaction time to promote uniform contact.
Starch-targeted cleavage can help dismantle polymer-bound filter cake and recover flow. Screen placement and reaction time for uniform cleanup.

Starch
Target starch polymers in drilling-fluid viscosity and cleanup trials.
Cellulose
Evaluate breakdown of susceptible cellulose-based drilling-fluid additives.
Xylan
Target xylan polymers where present in the fluid or plant-derived residues.
Potential cleanup benefits depend on polymer susceptibility and a validated treatment. Images illustrate the source polysaccharides used in drilling-fluid additives.
Compare enzyme activities, blend ratios, doses and treatment times in your complete drilling-fluid formulation.
Screen at the intended pH, temperature and salinity, including the actual polymer grades, solids and other additives.

Identify polymers, brine composition, additives and operating conditions. Send representative fluid and filter-cake samples.
Compare activities, doses and contact times with untreated controls. Measure retained activity, polymer breakdown and rheology.
Assess representative filter-cake removal and permeability before planning field treatment and scale-up.
Enzymes cleave susceptible organic polymers into smaller fragments, helping weaken the filter cake and remove residues that restrict flow. Develop the treatment around your polymer grades, reservoir and operating conditions.
Production, permeability and cleanup uniformity are potential outcomes of a validated treatment. Screen enzyme activity, dose, contact time and placement; rapid polymer cleavage alone does not establish uniform downhole coverage.

Removing a flow-restricting filter cake can reduce resistance between the reservoir and the well, helping recover production or water injectivity.
Breaking down accessible polymer residues can help restore near-well permeability. Confirm the response through filter-cake removal and return-permeability testing.
Match the enzyme to the polymer for targeted cleavage. A suitable treatment may reduce reliance on aggressive acids or oxidisers for the organic component; mineral bridging solids require complementary chemistry.
Controlled breaker kinetics and fluid placement can help maintain contact along a horizontal interval, reducing early leakoff through the first section cleaned. The complete treatment must be designed and tested for this outcome.
These blends target susceptible polysaccharides; they do not directly digest petroleum hydrocarbons or dissolve calcium carbonate. Xylan is distinct from xanthan gum. Outcomes must be confirmed for the selected formulation.
