(Enzyme Chemistry – simplified)
Filter cakes often contain a network of hydrated polymer chains (and sometimes solids) that block pore throats and reduce permeability. BIOFILTER™ uses targeted hydrolytic enzyme activity to cleave polymer linkages within this network, reducing molecular weight and weakening the cake structure. As the polymer matrix breaks down, the cake becomes easier to disperse and remove during circulation, displacement, or flowback.
In simple terms: enzyme → polymer matrix breakdown → cake loosening → improved permeability / cleanup
Typical range: 0.05% – 0.50% (system dependent)
Dosage is influenced by:
✅ Best practice: jar testing / core testing / pilot trials to validate removal efficiency.

Compliance & quality
Primarily polymeric filter cakes formed from guar, starch, and cellulose derivatives used in drilling and completion fluids.
By degrading polymer networks that block pore throats, BIOFILTER™ can help restore near-wellbore flow efficiency (system dependent and best validated by testing).
BIOFILTER™ is designed to reduce reliance on mechanical intervention in many polymer-dominated cakes. For complex cakes with heavy solids or specific mineral scales, it may be used as part of a combined treatment program.
Yes, generally compatible—however additives, salinity, and temperature influence activity, so lab testing is recommended.
Typically during cleanup pills / pre-flush / displacement, or in post-drilling circulation prior to completion operations.
